Three findings emerge. (1) The most important determinant of access of these farmers to more modern markets is their territorial (spatial) context and the way in which those territories interact with different markets, followed by fixed capital assets. Farm size, education and participation in organizations are not significant determinants. (2) Farmers working in the more modern markets compared to those in the traditional markets, are labor-constrained and overuse chemical inputs to a lesser extent. (3) Farmers that have accessed the more modern market channels, have substantially higher net income per hectare. Policies and projects aimed at promoting the inclusion in more modern markets of small-scale farmers such as those producing guava in Michoacán, must act on the territorial dimension of the problem of inclusion/exclusion, and not restrict themselves to actions aimed at improving the supply chains or the capacities of the households or their farms and organizations. Key words – Mexico, horticulture, supermarkets, wholesale, rural development.

SUPERMARKETS and MICHOACÁN GUAVA FARMERS in MEXICO
1. INTRODUCTION
In 2004 supermarkets in Mexico for the first time sold more food than did traditional
retailers, achieving a market-share of 57% (supermarkets and chain convenience stores
combined, with a 49% share for hypermarkets/supermarkets, and 8% for chain convenience
stores), up from 5% ten years ago (Acosta, 2005). In the five years leading to 2004,
supermarkets expanded their food sales by 144% (PECC, 2005), and the traditional retail
sector was displaced at 2% a year! Left behind are the traditional forms of food retail: central
markets (Centrales de Abasto), open-air fixed or mobile markets (tianguis), municipal
markets, and family-owned and operated neighborhood stores (tiendas de abarrotes), which,
however, continue to serve the poor and those living in remote areas (PECC, 2005;
Schwentesius and Gomez, 2002)1.
Concentration and multi-nationalization of food retail markets are nearly universal
correlates of the rise and spread of supermarkets in Latin America (Reardon and Berdegué,
2002), and Mexico is not an exception. The supermarket sector in Mexico is dominated by
only four chains whose sales account for 76% of the industry, or 43% of the food retail
market (PECC, 2005). The local subsidiary of Wal-Mart leads with about 41% of the industry
food sales (Euromonitor, 2004, cited by PECC, 2005). Since opening its first store 14 years
ago, Wal-Mart de México reached sales in 2005 of almost $ 16 billion (5% of its global
banner sales) through its 420 stores in close to 100 cities, of which 95 stores in 60 cities were
opened in 2005; on average, each Mexican citizen shops 7 times per year in a Wal-Mart
store2.
The supermarket market share of fresh fruits and vegetables (FFV), at around 28%
(Acosta 2005), is significantly lower than their share of total food retail, a trend observed in
3
many countries, both developed and developing (Reardon and Berdegué, 2002) – but steadily
taking share from the traditional sector. In 2000, traditional retailers sold FFV at a
substantially lower price than the supermarket (Schwentesius and Gomez, 2002), while at the
same time offering a broader spectrum of quality and ripeness, which allows them to tailor
their supply to the preferences of different groups of consumers. Four years later, evidence
emerged that the price gap is closing; Martínez (2005) cites preliminary evidence (from
2004) that for 7 of 10 key produce items in Mexico City, at least several of the leading chains
sold at or lower than the price of the traditional retailers.
Consumption of fresh fruits and vegetables in Mexico is growing by over 10% per
year among the low income social strata, and by more than 3% per year in the high income
households (Acosta, 2005), and the participation of the supermarket sector is growing at a
faster rate than that shown by traditional retailers. In addition, the smaller share of
supermarkets is dominated by a handful of very large firms, while the larger market share of
the traditional sector is dispersed among close to half a million very small stores; hence, due
to market concentration and economies of scales, supermarkets exert an influence along the
FFV supply chains which is far greater than their market share.
It has been shown elsewhere (Reardon and Berdegué, 2002; Berdegué et al., 2005;
Vorley et al., forthcoming) that the rise of supermarkets is correlated with disproportionate
opportunities for the larger producers or more capitalized small producers or both, and
typically exclusion from the dynamic food retail markets of the least-capitalized smaller
farmers, which of course are the majority of producers. Our hypothesis is thus that small-
scale and poor producers face significant difficulties in implementing the technological,
organizational, managerial and financial changes that are required to meet the grades and
standards and other contractual conditions of the supermarkets’ FFV procurement systems.
Widespread exclusion of the Mexican smallholder sector from the dominant and fastest-
4
growing food retail market, would have significant social, economic, political and even
international repercussions, in a country where about half the rural population is poor and
where literally tens of thousands of farmers each year leave their homes to become
undocumented migrants in the USA or to be underemployed in the informal economy of the
large Mexican cities.
This paper addresses the following questions: (1) What are the determinants of access
to the supermarket market as compared to the traditional market?; (2) What are the
technological, organizational, and managerial changes at the farm and farmers’ organization
levels that are concomitant to participation in the supermarket market, and what are their
financial implications?; and (3) What are the costs and benefits to farmers of these changes?
The paper proceeds as follows: Section 2 presents the data and methods. Section 3
presents findings, first with a summary of the main findings that are then substantiated by the
evidence introduced progressively in the rest of the paper, second with a basic description of
guava (Psidium guajava L.) production and producers in Michoacán and their marketing
systems; third with a description of guava supply chains leading from Michoacán to the
supermarkets; fourth with an analysis of different types of farmers according to the type of
supply chain in which they participate predominantly, and last with a presentation of the
results of our econometric analysis of determinants of access to more-modern-market
channels, output supply and input demand, and production relations, followed by an
evaluation of allocation and technical efficiency. Section 4 presents the conclusions and the
policy implications of our study.
2. DATA AND METHODS
The study analyzes the case of guava producers from the state of Michoacán
(population, 4 million). The state is located in the Central-Western part of Mexico, with its
5
capital city, Morelia, about 280 km northwest of Mexico City. Michoacán was selected as the
site of this study for the following reasons: (1) in the past decade, the agricultural sector in
Michoacán has grown at a rate substantially higher than the national average, led by a very
rapid expansion of fruits such as avocado, guava, strawberries, pears, peaches, lemon, and
grapefruit; (2) over 50% of the agricultural land is in the hands of small-scale producers
(ejidatarios), which include both market-oriented and subsistence farmers; (3) the state of
Michoacán has a decades-long tradition of small farmers’ organizations; (4) there is a strong
private sector in Michoacán of traders, agribusinesses, and agro-processors; (5) the state
government has put in place a vigorous, market-oriented policy of agricultural development,
with a strong bias in favor of small-scale farmers and their organizations. Hence, the
Michoacán agricultural sector, and its small farmers in particular, are in principle well poised
to participate in the supermarket revolution in Mexico.
Guava was selected because: (1) small growers produce a very high percentage of the
national harvest; (2) there are large variations in quality and productivity, which in principle
correlate with access to different markets; (3) the production areas are quite concentrated
geographically and this facilitates the study, and; (4) the Michoacán State government has
prioritized guava and guava small farmers in its support programs.
The data sources included: (1) a one-month (June-July 2005) very detailed rapid rural
appraisal in all the guava-producing municipalities of Michoacán, which included dozens of
interviews and meetings with members of numerous guava farmers’ organizations and ejidos
(rural communities that originated in the Agrarian Reform, but with independent, family-
owned and managed farms), large and small guava traders (retailers, wholesalers,
supermarket agents), officials from the municipal, state and national government agencies,
etc.; (2) a survey of 25 guava wholesalers and retailers in Mexico City, including
supermarkets and traditional retailers, by far the most important market of Michoacán
6
producers; (3) a survey of several different types of retailers in traditional retail markets in
Mexico City; (4) a household and farm survey of a representative sample of the state’s guava
producers.
The sample for the household/farm survey was drawn from a sampling frame of
(nearly) all the guava producers in Michoacán, compiled during the rapid rural appraisal from
the lists of members or beneficiaries of the guava farmers’ organizations, the Local
Phytosanitary Boards (Juntas Locales de Sanidad Vegetal), the ejidos, and the government
projects and programs; several key informants agreed that it was highly unlikely that a guava
farmer did not belong to at least one of those organizations or projects, and, in fact, it was
usual that the same name appeared several times in the initial, pre-filtered list. A random
sample of 373 observations was drawn from the list of 3,337 guava farmers; the sample is
randomly distributed in the nine municipalities in which there is guava production in
Michoacán. The sampling error is of 5% with a probability of 95%. The survey was done by
six enumerators and two field supervisors between 23 August and 15 September 2005.
3. RESULTS
(a) Preview of key findings
In this paper we provide evidence that leads to the following main findings of our
research:
(1) The supply of guava from Michoacán to supermarkets – even to the largest
multinational chains- in Mexico in 2005 was heavily dependent on the complex, diffused
supply networks ultimately developed and governed by wholesalers in the traditional Central
Markets (Central de Abastos) of Mexico City and other large cities. This is not what we had
expected at the outset; extrapolating from recent findings in Nicaragua, Guatemala,
7
Honduras, and Costa Rica (Balsevich 2005; Balsevich et al., 2006; Hernandez et al, 2006.),
as well as from recent research on supermarkets, wholesalers, and producers of tomatoes (a
mass domestic market commodity also heavily exported) in Mexico (Cook and Reardon
2006). We had hypothesized that we would find again - in the Mexican guava sector -
heavily centralized supply chains, firmly and directly governed by supermarket firms through
their procurement officers. In our original hypothesis, these centralized chains would link the
Distribution Centers of the supermarkets, dedicated and specialized wholesalers, and
preferred suppliers (farmers), using clearly defined private grades and standards and quasi-
contractual arrangements as the institutional beacons to be dutifully followed by all the
agents in the chain (Reardon et al., 2005; Berdegué et al., 2005).
(2) As different branches or subsystems of the diffuse supply networks that we instead
found, one can find some that link the most powerful wholesalers in the Central Market of
Mexico City (and other major urban centers), and the farmers in the best guava production
areas, that is, those regions were there is an abundant supply of high quality fruit, and where
the access (road) conditions are favorable (or at least, not as bad); these relatively more
modern branches lead (although not exclusively or even primarily in terms of volume) to the
supermarkets and other dynamic retail markets. Other branches are served by the small,
traditional, very informal, largely local, and much hated intermediaries (called coyotes by
Mexican farmers); they source their guava from different areas, ones with less abundance of
good quality fruit, and with more difficult access; the fruit is then sold in local markets, in
street fairs and in small neighborhood stores, although much of it also reaches the Central
Markets of Mexico City and other major urban centers.
(3) These two subsystems are spatially segregated, since, as we will explain, the
former (more modern market channel) is dominant in the Eastern region of Michoacán, and
the latter (the traditional channel) rules the Central region of the state. Hence, there is a very
8
important territorial determinant of (modern) market access. We now hypothesize that under
the conditions found in guava in Michoacán in 2005, farm and farm household characteristics
(in terms of access to physical, financial, social, and human capitals) in a sense are ‘second
round’ determinants of market access.
(4) This territorial determination of market access in the case of guava in Michoacán
has resulted in one virtuous and in one vicious cycle, also spatially distributed, that reproduce
the co-existence of the two supply networks, driving the preferred regions and the farmers in
them closer and closer to the more dynamic markets, and those in the other areas more and
more away, in a kind of ‘spatially determined path dependency.’ This is consistent with Peter
Timmer’s (2004) prediction that the dynamics of diversification of consumer preferences,
plus the economies of scale of the supply systems of supermarkets, would lead to regional
specialization. This finding is also consistent with the theories of neo-economic geography
(e.g., Krugman, 1995)3. More developed and financially stronger buyers, serving modern
markets, buying fruit in the best regions, provide better incentives to farmers, who in turn do
more (and here is where the household- and farm-level determinants come in) to respond to
the grades and standards and other conditions characteristic of that supply chain. Less
developed, financially weaker buyers, serving traditional and declining markets, operating in
the less favorable regions, do not provide sufficient incentives to the farmers, who in turn
have less or no reason to enhance their yields, fruit quality, or productivity, since no matter
what, their efforts tend to go largely unrewarded.
The policy implications of these findings will be discussed at the end of the paper.
(b) Basics of guava producers and production in Michoacán
Guava production in Michoacán took off in 1997, after a very harsh winter in the
then-leading production areas in the state of Aguascalientes caused substantial damage to the
9
guava orchards and resulted in a sharp drop in production and in abnormally high prices.
According to Mexico’s Ministry of Agriculture statistics, in 1992 Michoacán was a distant
third in guava production in Mexico, with less than 9000 tons (about 5% of the total national
supply). Since then, the Michoacán guava acreage grew by an average 19% per year,
production by 31% per year, and yields by 9.4% per year. As a result, in 2001 Michoacán
became the leader in guava production with 39% of the supply (over 100,000 tons). Our
survey results allow us to estimate that in 2005 Michoacán produces slightly less than
160,000 tons, which is equivalent to 50-55% of the total national supply. Between 1998 and
2005, the number of guava farmers in Michoacán has increased by 38%. In short, since the
start of the guava expansion in 1997, the state of Michoacán has duplicated yields, increased
the area by two thirds, and tripled production. Guava makes a substantial contribution to
Michoacan’s rural economy also through the labor market, as the annual labor costs add up to
approximately $ 9 million (nearly a million laborer-days).
Within the state of Michoacán there are two distinct guava growing areas: the Central
zone, around the municipality of Taretan, and the Eastern zone, near the city of Zitácuaro,
that includes the municipalities of Benito Juárez, Jungapeo, Zitácuaro, Susupato, Tuzantla,
and Tuxpan. In the year 2005, 90% of the guava producers were in the Eastern zone, and
within it, 61% in the municipalities of Benito Juárez and Jungapeo.
The Central zone lagged behind the Eastern zone in the expansion of guava orchards,
by about 3-4 years. From the rapid rural appraisal it appears that a major reason behind the
delayed response in the Center region were the significant government social, price, credit,
and input subsidies directly linked to sugar cane production, the predominant crop in this
area. To this day and despite the fact that sugar cane is far from being a profitable crop, two
thirds of guava farmers in the Central zone still maintain a significant part of their land under
sugar cane, as this gives them direct access to social security and other social benefits. The
10
farmers in the East, dedicated as they were to maize and low-productivity cattle production,
as well as areas of earlier commercial small-scale horticulture, did not have this incentive to
hold back, and immediately responded to the positive price shock resulting from the 1997
frosts in Aguascalientes4. We will later show what a major difference this delay of 3-4 years
has made in terms of actual and potential market access, in the context of the very rapid speed
of the change processes driven by the expansion of supermarkets in Mexico.
Guava orchards have on average 2.3 hectares, and on average each farmer has 1.2
orchards (although some have up to 5 orchards). The orchards of each farmer are of different
age, as the new plantings have been financed in large part with the profits from previous
years. It is also observed that the several orchards, belonging to different family members, are
managed by one of them as a single production and business unit.
Each orchard is subdivided into several sections. This allows a system of orchard
management that revolutionized the guava supply in Mexico by allowing a more or less
constant production of fruit throughout the year, while in the past guava used to be a highly
seasonal product. This is done by staggering the pruning of the different sections of each
orchard. The length of the growing and the harvest cycles is also influenced by the average
temperature (as affected by altitude and other location attributes of the orchard). The
combination of several orchards in different places and of several sections in each orchard
pruned at different times, results in a farmer having fruit to sell up to 3 to 5 times throughout
the year; this may have been a factor that facilitated the establishment of more or less stable,
longer term relationships between producers, informal local brokers and intermediaries, and
wholesalers, which are a distinctive characteristic of the guava supply chains, as will be
discussed below in more detail.
Table 1 summarizes some characteristics of the producers. Of importance to our
discussion below are: the significantly greater experience in guava of the farmers in the East
11
zone; the greater reliance of guava farmers in the Central region on family labor; the greater
dependency of the economically active household members in the Central region on guava
production as a source of employment. There are no differences in the very low levels of
schooling of guava farmers, the majority of which have less than complete primary
education.
Table 1 also shows that the average farm size is below 3 hectares, but that farms in the
East are somewhat larger than in the Central region; that guava orchards in the East are twice
as old as in the Central zone (leading to much higher average yields and better average
quality), and; that the orchards in the East are significantly closer to paved roads. On the
other hand, there are few differences between both regions in terms of the type of agrarian
regime (95% family-owned ejido farms). Basically all guava orchards are irrigated; water is
cheap and abundant and irrigation techniques (orchard flooding) are very inefficient, a factor
which guava experts identify as a major source of nematode (fought with highly toxic
chemicals) and fruit yield and quality problems. The abundance of cheap water for irrigation
is a major competitive advantage of Michoacán against the former leading area of
Aguascalientes, which depends on (expensive) deep wells.
A very important indicator of the profitability of guava production in Michoacán is
that between 20% and 30% of the land in our sample planted with guava, depending on the
region and the municipality, was actually bought and not inherited by their current owners.
Over 85% of the farmers in our sample declared being members of at least one local
organization, the ejido and the Local Phytosanitary Boards being the predominant ones.
Although there is a huge number of small farmers’ economic organizations in all the
municipalities and almost each guava farmer seems to belong to more than one, participants
in the Rapid Rural Appraisal agreed that with very rare exceptions, they are inactive since
they were set up as formalities to be able to fulfill the requirements of the different
12
government programs which discourage services to individuals and want to ‘promote’
collective action for production, market access and other such objectives.
Table 1 shows that the expansion of guava has been financed mainly through the
reinvestment of profits from previous crops (58% of households in the Central region, 36% in
the East), sale of cattle (23% and 31%), and remittances from migrants (about 20% of
households in both regions). Less than 12% of the households in each region have had access
to formal financial services, either from government or private sector sources, to finance their
guava orchards. This result confirms the limitations of rural financial services in Michoacán,
a fact that will come into perspective when we present evidence that shows that fixed capital
assets are one of the main determinants of access to the more developed and profitable guava
supply chains.
Table 1 shows that technical assistance and advice for guava farmers comes basically
from two sources: their neighbors and the distributors and salesmen of agricultural chemical
inputs. It is then no surprise to find that guava farmers - in particular those most isolated from
the more developed market channels - over-fertilize and over-spray their orchards. This major
gap in the provision of technical assistance services undermines the effectiveness of the
investment by the Federal and State governments of close to $ 2 million in 2004-2005 in
production and marketing development projects specifically aimed at Michoacán guava
farmers (about $ 256/guava farmer/year). The econometric analyses below will confirm that
guava farmers are over-using fertilizers and in particular chemical pesticides, and that this has
a major impact in the profitability of the crop, in particular for farmers working in the more
traditional markets.
Table 1 also shows the average guava orchard yields in each region, with the East
almost duplicating those of the Central zone. A comparison of same-age orchards confirms
that yields are lower in the Central region for all age categories. Constructing from our data
13
two hypothetical guava farms, one in the East and one in the Central zone, using the average
yields for each 1-year orchard age category from 0 to 20 years, one concludes that over a
two-decade period, a guava orchard in the East will produce about 370 tons of guava,
compared to only 109 tons of the ‘farm’ in the Central zone. While natural factors such as
temperature, rainfall of soil quality certainly play a role, there is a strong correlation in our
sample between average yields and variables such as farmer experience and the prevalent
technologies in use (particularly, greater use of fertilizers in the East), and these patterns
show a clear spatial distribution as shown above.
Table 1 also shows the percentage of each farm’s production under each fruit quality
category. Again, the Central regional is at a disadvantage. Of the slightly more than half of
the fruit in the Central zone that is sold in boxes graded by quality, only one fifth is of Extra
or Super Extra quality, the top two grades. In contrast, in the East 74% of the fruit is sold
graded, and of that 40% is of top quality. Selling the fruit packed in graded boxes is a clear
sign of market development, and an important step beyond selling it ungraded by boxed,
which in turn is better than selling the fruit before it is harvested. The reader should note that
in both the qualitative and the quantitative surveys, we recorded the quality of fruit according
to the farmers’ own classification and perception.
Why would farmers in the Central region sell their fruit ungraded? Because on
average they get paid the same $0.20 per kilo of the best (Super Extra) or the worst fruit
(Seconds), while in the East there is a 266% price differential between the extreme qualities,
and analogous differences between the intermediate grades. And what explains these stunning
differences in the way farmers get paid in one or another region? The basic answer to these
questions is that in the Central zone, half of the harvest is bought by the local intermediaries
(coyotes), and 40% is sold in the local (Michoacán) market. In contrast, in the prime
municipalities of the East up to 78% of the fruit is bought by wholesalers, and only 13% is
14
sold in the local market while 57% goes to Mexico City. On average, across all qualities of
fruit sold graded, the price paid to the farmer when the fruit is sold in Mexico City is 22%
higher than the price she gets is the fruit goes to the local market.
(c ) The guava supply chains
In November-December 2005 we interviewed 25 wholesalers in the Central Market
(Central de Abasto, CEDA-CM) of Mexico City, including 12 working directly for different
supermarket chains, others supplying the supermarket suppliers, and some supplying
traditional retail systems. CEDA-CM occupies 328 hectares in which 3700 wholesale and
retail stores operate, 51% of them buying and selling each day 13,000 tons of fresh fruits and
vegetables (FICEDA, 2005). Echánove (2002) estimated that 12% of Mexico’s fresh fruits
and vegetables are sold in this market. CEDA-CM supplies 80% of the perishable products of
Mexico City, one of the largest urban areas in the world, and 15% of the neighboring states.
According to the management of CEDA-CM, around 100 fresh fruit and vegetable
wholesalers (5% of the total) are direct suppliers of supermarket chains. This is consistent
with the findings of Torres (2003). Of the 120 guava wholesalers in CEDA-CM, based on our
interviews we estimate that no more than 12 are regular, direct suppliers of supermarkets, and
even they (with the exception of one) sell to a variety of clients, including other wholesalers
and traditional and modern retailers different than supermarkets. It is safe to say that
supermarkets, large and small, domestic and multinational, source no less than 90% of their
guava from CEDA-CM; there are no reliable statistics on the absolute volume or value of this
transaction.
A few medium-small supermarket chains with stores mainly or solely outside Mexico
City (HEB, San Francisco de Asís, Arteli and Futurama), keep offices and warehouses in
CEDA-CM, to receive the produce sourced from wholesalers in the same market. From there,
15
these chains send the produce to their Distribution Centers and/or stores in the different cities
where they are present.5 Arteli, with 21 stores in the states of Tamaulipas and San Luis
Potosí, in the North of Mexico, does not source its guava from the nearby large production
region of Calvillo, Aguascalientes (second most important after Michoacán); the small
amounts of guava required on a daily basis do not justify sending a truck to the production
area, and is more efficient to receive a truck from far-away CEDA-CM loaded with a number
of different products, a move that according to the procurement office of that chain results in
lower average transport costs. The San Francisco de Asís chain, with 40 stores in the
Southeastern states of Yucatán, Campeche and Quintana Roo, used to source guava from
CEDA-CM until 2-3 years ago. Now it sources from production areas closer to their stores, a
move taken to reduce transportation costs. Hence, it can be seen that transportation costs and
economies of scales not only of an individual product but of a basket of similar products, are
important variables in the decision to source from CEDA-CM or directly from the production
regions.
The large chains with stores in Mexico City, such as Wal-mart, Gigante, Comercial
Mexicana, Chedraui, or Grupo Cifra, also source almost all their guava from CEDA-CM.
According to the wholesalers who are direct guava suppliers of these major chains, some of
these chains – who require relatively large quantities of guava consistently through the year -
have tried to source directly from producers, but have concluded that working through
CEDA-CM they reduce cost of the constant selection and repackaging that is required
because of the very perishable nature of guava (it lasts in adequate conditions a maximum of
1 or 2 days) and the inconsistent grading done at the farm level, which results in the need to
constantly reselect, grade and package in the wholesaler’s warehouses. Guava, being a small
volume fruit compared to others such as apples or bananas, does not justify having special
16
cold storage areas, and the fruit is immediately damaged if it is stored at the low temperatures
that are adequate for these other fruits.
Another important reason for these large chains sourcing from CEDA-CM, according
to these same sources, is that these large wholesalers can absorb the price discounts imposed
unilaterally by the chains to compensate for damaged, unsold guava, a condition that the
small or even the relatively “large” guava producers could not sustain. Also, according to
these wholesalers, the chains can negotiate better prices with large-volume wholesalers than
with the producers. It could be that in a product such as guava in Michoacán, where almost
all of the production comes from a large number of small farms, supermarkets may have
more difficulties and/or higher costs that slow down the process of supply chain
concentration, compared to other crops in which medium and large farmers can meet a
significant percentage of the supermarket’s demands – such as is the case for tomatoes to
supermarkets in Mexico (Cook and Reardon 2006). In the latter situation, it would be easier
for the supermarkets to put in place their preferred centralized supply chains as described by
Reardon and Timmer (2005) and Berdegué et al. (2005). Of course, collective action through
effective small farmers’ organizations in theory could also make it more feasible for the
supermarkets to establish direct links with producers, even if they are small. In fact, the
examples of PROGOMICH in Michoacán with an old (and failed) arrangement with Wal-
Mart and their ongoing contract with the SORIANA chain, as well as other similar cases in
the state of Aguascalientes, show that this is an avenue already being actively tested by
different supermarket chains; unfortunately, several of these experiences have been
unsuccessful, and those that seem to be doing well still represent more the exception than the
rule, or at least are still only emerging experiences. Finally, during the rapid rural appraisal
we became aware that some of the local brokers and the local (larger) wholesalers that collect
guava from several small farmers to take it to Mexico City’s Central Market, are also starting
17
to provide the same service for some supermarkets, in what may be that initial stages of a
process of development of specialized guava brokers and wholesalers dedicated to servicing
supermarkets thanks to their capacity to coordinate a number of farmers in a given region.
These large wholesalers, with direct relationships with the supermarket chains, buy
their guava from different sources: (a) directly from guava producers (some of whom also act
as intermediaries with other producers) with whom they often have had a long commercial
relationship, so that the producer ships the fruit to Mexico City and the wholesaler makes the
payment a few days later; (b) from guava producers who operate through informal local
brokers called ‘fleteros’ (often guava farmers themselves) that collect guava from several (4
to 10) small farmers, provide transportation to the CEDA-CM, receive the payment from the
wholesaler for the fruit delivered the previous week or so, and take the payment back to the
producers, charging a fee for his services; (c) from the more classical intermediaries (coyotes)
who buy the fruit either from farmers, or from other, smaller and even more informal
coyotitos; (d) from wholesalers based in the main production areas of Michoacán and other
states, some of whom are also producers; (e) from wholesalers who on their way to Mexico
City from other production regions in the North of the country (Aguascalientes), detour to
buy fruit in Michoacán to take to Mexico City; (f) from other wholesalers in the CEDA-CM
who fill in their orders according to need, and who in turn used one of the previous channels
to obtain the guava. Very frequently there are long-standing relations between the
wholesalers in CEDA-CM and the agents in these different supply chains.
Most of the fruit that arrives in CEDA-CM is received and sold by the wholesaler on
commission, and a service fee of between $ 0.5 and $ 1 per 13-kg box is charged. In addition,
if a fletero was used to facilitate the transaction, the wholesaler pays another $ 1 per 13-kg
box to the fletero for his intermediation and transportation services, and this amount is
deducted from the payment to the farmer; which is made on a weekly basis. Only in rare
18
occasions will a wholesaler buy the fruit on reception, in which case the payment is made in
cash on the spot.
All the guava thus received by these large wholesalers who supply to the
supermarkets, upon arrival to the warehouses is taken out of its boxes and reselected,
regraded and repackaged in new boxes according to the standards and conditions of their
different clients6. The quality standards used by the supermarkets are those of the traditional
markets, but they buy fruit that attains certain grades: extra and ‘first’ size, of green color (not
mature), and consistente (firm). According to the wholesalers, the chains Superama
(belonging to Wal-Mart) and Chedraui insist on buying only the best quality. According to
our informants, the chains do impose temporary or permanent penalties, up to delisting, on
suppliers who fail to meet their quality standards.
The type of and size of the packages varies among chains and, in some cases, among
different store formats within the same chain, as in the case of Wal-mart which requires
plastic boxes of 12, 15 and 20 kilos for most of its stores, but in small plastic cases of 950
grams for Wal-Mart’s Sam’s discount format. (The use of plastic boxes is a packing
technology change that is diffusing in the market, as the traditional packing is in wooden
boxes and recently in cartons.) The fruit is then sent to the Distribution Centers of the
supermarket chains and, occasionally, to individual stores.
Payment from the chains is received by the wholesalers in 30 to 45 days, with the
exception of Comercial Mexicana that pays after 15 days. In addition, the chains regularly
apply discounts of between 7% to 10% for ‘publicity and for damaged or unsold fruit’. Each
chain has one day in the week, or sometimes a full month, when it offers deep discounts to
consumers on purchases of fruits and vegetables; these discounts are transferred in full to the
wholesalers who supplied the fruit.
19
A few supermarket chains source a small fraction of their guava through free agents
called ‘introductores’ who play a role similar to the ‘fleteros’ relative to the CEDA-CM
wholesalers. Finally, there has been a handful of experiences – mostly failures from what we
could learn in our rapid rural appraisal - of supermarkets sourcing directly from formal or
informal associations of groups of producers. One such case is that of PROGOMICH, an
organization of small guava farmers active in several municipalities of the Eastern zone of
Michoacán, who supplied guava to Wal-mart in 2004. Despite the very favorable price
conditions and the very strong technical and financial support from the Michoacán state’s
development programs, the Wal-Mart/PROGOMICH deal fell apart within one year as the
farmers’ organization was unable to coordinate sufficient producers to consistently, week in
and week out, meet the volume and quality conditions imposed by the supermarkets.
In addition to the large wholesalers selling to the supermarkets, there are in CEDA-
CM dozens of smaller wholesalers (‘revendedores’) who sell guava in 13 kg boxes to
traditional retailers of different kinds (tianguis or mobile street markets, fixed street markets,
municipal markets, and small processors/retailers such as juice and ice cream makers). While
much of their fruit is bought from the larger wholesalers, these revendedores increasingly are
sourcing directly from producers thanks to the services of the informal brokers or fleteros,
who often can be relatives or close acquaintances.
(d) Typology of guava farmers in Michoacán
To begin answering the research questions, a non-hierarchical cluster analysis was
done with the household survey data. The households were classified into five clusters
according to the variable percentage of fruit sold to buyers in the “MMM” (more-modern
market) channel, explained below.
20
Table 2 shows the results of the cluster analysis. The variable “MMM” requires a
detailed explanation, since given the diffuse nature of the guava supply chains, there is no
clear, direct, unequivocal path from one farm to a single form of retail market, and, de facto,
the farmers are working in a multi-market context. This market channel variable has been
calculated as both continuous and a categorical variable that can take on two values: more
modern or traditional. Continuous is defined as sales to the modern channel over total sales
which takes on a range of values from 0 to 1 and in this form is used for the cluster analysis
above. The categorical variable (used in the market channel determinants model below)
considers if a farmer sells the majority of his/her guava to one or more of the market
intermediaries that we classify in the “MMM,” then that farm is assigned as a “MMM”
farmer. If not, he/she is a “traditional channel” farmer. The set of intermediaries classified in
the modern channel are: (1) local wholesalers; (2) non-local wholesalers; (3) supermarket-
servicing ‘introductores’; and (4) farmers’ organizations. Those in the traditional channel are:
(1) the farmer /her/himself as own marketer; (2) the local small-scale informal, traditional
intermediaries (‘coyotes’); and (3) local informal brokers-truckers (‘fleteros’).
There are several important things to note about the categorical variable observations
and their interpretation. First, the goal in constructing this variable is to bifurcate the sample
into farmers whose fruit is more likely to be sold in a supermarket versus those not. Doing
this directly and simply was not possible, due to the fact that few if any of the farmers sell
directly to supermarkets, and many intermediaries in turn sell to other intermediaries before
the guava arrives at the retailer. Moreover, apart from the supermarket-servicing
‘introductores’, all of the above intermediaries in theory could eventually sell to a
supermarket. But we know, from the rapid rural appraisal qualitative information, as well as
from the survey of wholesalers in Mexico City, that some of the intermediaries are
21
substantially more likely to sell to the supermarkets or to wholesalers who sell to the
supermarkets, and others less so.
Resource limitations kept us from being able to do a quantitative survey of the
intermediaries, which would have allowed us to estimate the conditional probability
distributions, per intermediary type, of that intermediary’s selling in the supermarket channel
versus the traditional channel. We thus generated rough working hypotheses, based on our
qualitative information, of which intermediary types sell most of their guava into more formal
channels from which supermarkets source, and which not. The upshot is that we cannot with
any confidence say what is the specific probability of selling to supermarkets associated with
a given channel. Rather, the distinction of the channels reflects our qualitative estimation of
the relative probabilities of one set of intermediaries being more likely to sell to supermarket-
markets. Thus, the categorical variables are subjective (but informed) categories that
represent different distributions, the modern being more (but we cannot estimate precisely
how much more) centered in the formal market supplying the supermarkets, and the
traditional not.
Second, there is variation over the intermediaries in a given vector (associated with a
given channel) of classification error, but we believe that the “center of gravities” of the two
channels are indeed substantially differentiated. On the one hand, in the modern channel, our
qualitative survey gives us confidence that there is low classification error for non-local
wholesalers, organizations, and introductores, all of which have a notably higher chance of
selling to the formal channels than are most of the intermediaries we have classed in the
traditional channel. There is probably higher classification error for the case of the “local
wholesalers” as they sell to both channels; they were assigned to the modern channel mainly
because of local subjective assessments; farmers tended to use the term “wholesaler” for
larger intermediaries who take possession, have larger trucks, and operate on more formal
22
terms, and farmers typically contrast those with the other local group that takes possession,
the small intermediaries (coyotes) who they say focus on the informal sector retail and
wholesale – so the assignment of local wholesaler to modern was done on the basis of this
bilateral comparison. Note that in all cases, we do not make the classification on how the
farmer and the intermediary transact (contractual, payment mode, delivery mode such as via a
third-party transport or directly, and so on).
On the other hand, in the traditional channel, the qualitative survey makes us
confident that there is low classification error in the case of the small intermediaries
(‘coyotes’) and farmer-direct marketing. There is, however, probably higher classification
error in the case of the local, informal brokers of ‘fleteros’. This agent is by nature
ambiguous in our context, as he does not take possession (as opposed to what the other
intermediaries do) and so could sell to any of the other intermediaries in either channel. We
put that agent in the traditional channel because of a subjective reason observed in the survey
pretests: farmers tended to waffle between coyote and fletero when they were indicating that
a local small-scale player marketed their product.
Third, the upshot of the above is that the cluster (and later, the econometric) results,
thus show the effects of various determinants on the probability of a farmer being a given
category – a category which reflects a subjectively (qualitatively) determined conditional
probability of marketing to a channel that ends in a supermarket versus a traditional retailer.
Table 2 shows that slightly more than half of the farmers (Cluster 1) sell no guava at
all to the MMM, while 30% of the farmers (Cluster 5) sell all of their fruit to MMM. The
level of farmer inclusion in the more modern pole of the distribution, is very high compared
to other studies that have focused on highly centralized, supermarket-controlled supply
chains. What we see in Michoacán then is a very strong bimodality of market access.
Remember that this situation has taken shape in only 5-7 years, a very rapid process of
23
differentiation. This bimodality neatly corresponds to the two production zones, with 91% of
the farmers in Cluster 5 (all fruit to MMM) being located in the Eastern region. On the other
hand, being a farmer in the Eastern zone does not assure access to MMM, as half of the
farmers there are in Cluster 1 (all their fruit sold to the traditional market).
Looking now at the assets section in Table 2, a striking result is that farm size (access
to land) is not correlated to access to MMM; this is very good news to small guava farmers.
Other important factors that are not related to having gained access to MMM, include:
education, membership in farmers’ organizations, and access to credit.
On the other hand, age of the orchard is significantly different between Cluster 1 and
Cluster 5 farmers. It is seen that those farmers in Cluster 5 (high access to MMM) established
their orchards almost immediately after the initial price shock that catalyzed the expansion of
guava in Michoacán, while the orchards of farmers in Cluster 1 are two years behind; what a
difference 2 years appear to make when market change process are rapid and dramatic!
Access to technical assistance is another variable that is related to access to MMM,
and farmers in Cluster 5 have more sources of technical assistance than those in Cluster 1.
There are significant differences, all in favor of Cluster 5 farmers (100% MMM) in terms of
access to public and private technical assistance (including in this groups input salespersons
as well as farmer-to-farmer advice).
Table 2 also gives (indirect) evidence about the ways in which these farmers finance
the establishment and operations of their orchards. We have seen that there are no important
differences in terms of access to credit. Farmer households working only in traditional
markets (Cluster 1) tend to have more members working off-farm than those that gained
access to the MMM, and a greater proportion of them also receive remittances. On the other
hand, farmers in Cluster 5, working only in the MMM, rely more on the profits from other
crops and on sales of cattle. In addition, it can be seen that farmers in the MMM, tend to be
24
more specialized as guava producers, a finding that is similar to those of Balsevich at al.
(2006) and Hernández et al. (2006) with tomato producers in Nicaragua and Guatemala, and
Flores and Reardon (2006) with lettuce producers in Guatemala.
Turning now to the technological differences, the striking difference is that farmers in
the traditional markets (Cluster 1) have substantially higher costs per hectare than farmers in
the MMM (Cluster 5), including 22% higher labor costs per hectare7 and 53% higher costs in
agricultural chemical inputs different from fertilizers (i.e., insecticides, nematicides,
fungicides and herbicides). From the rapid rural appraisal we gathered that the agronomists
that we interviewed believe that chemicals are being over-applied and misused across both
regions and all types of producers but that this is a more acute problem in the more traditional
areas, while those better linked to markets, because they have access to more information and
advice form a wider range of sources, are more in tune with the broad issues surrounding
excessive pesticide use. This is markedly in contrast with what has been found in other
studies (Balsevich et al., 2006, Hernández et al., 2006) where a relationship has been
established between domestic modern retail markets and higher use of chemical inputs to
meet the quality grades and standards.
The ratio of labor to land is much higher in those in the traditional market (Cluster 1),
while those in the MMM have 54% more fixed capital as measured by an index that takes
into account the local prices of the most frequent types of equipment and machinery found in
these farms. This is a critical distinction: access to the more modern markets – at least so far -
is not constrained by farm size, but is definitely affected by access to capital, in the form of
trucks, screening, grading and packaging equipment, and so on. Balsevich et al. (2006),
Hernández et al. (2006), and Flores and Reardon (2006) reached the same conclusion in their
studies in Nicaragua and Guatemala: fresh fruit and vegetable farms in the more modern
markets may be small in size, but they need to be capitalized.
25
Farmers working in the MMM have higher yields and, hence, produce more guava.
The average price they obtain for their product is 28% higher than those selling to the
traditional market. As a result of the higher yields, higher prices, and lower production costs,
the net income per hectare of guava is almost 5 times higher for farmers in the MMM than
those in the traditional market, while if one counts as household income the cost of household
labor, then the total household income per hectare is twice as large for the farmers in the
MMM.
(e) Econometric results
We conducted several econometric tests on the household survey data focused on
answering the three research questions.
The first stage of analysis is an analysis of market channel participation by farmers.
This is undertaken both as an end in itself as well as to generate observations on the inverse
mills ratio (IMR) used to control for the conditional probability of a farmer being included in
a given stratum in the second stage analyses of production presented below.
The market channel adoption model is specified with one equation system as:
ijijjij XY εβ +=
where Yij indicates if the ith producer chooses the modern market channel j=1, or j=0
otherwise (traditional market channel). The probability of producer i selling to market
channel j=1 is represented by a function F(x, β ) where the vector x represents the farm and
producer characteristics that we hypothesized affect the market channel adoption and the
vector of parameters β represents the significance and effect of changes in x on the market
channel adoption. ijε is the error term.
The x vector contains the following variables:
26
(a) total guava area of the farm, measured in hectares;
(b) average age of trees on the farm, measured in years;
(c) education of the producer and measured as: none = 0, incomplete primary
school = 1, complete primary school = 2, incomplete secondary school = 3, complete
secondary school = 4, preparatory incomplete = 5, preparatory complete = 6, technical
incomplete = 7, technical complete = 8;
(d) age in years of the producer;
(e) producer’s gender; female is equal to one if the producer is female, 0
otherwise;
(f) distance to paved road in kilometers;
(g) organization membership, equal to 1 if the producers is member of an
organization, 0 otherwise;
(h) quasi-fixed capital, an index (sum of units weighted by price of
replacement) generated from equipment and machinery owned by the producer;
(i) region is equal to one if the producer is located in the East region and equal
to 0 if located in the Central Region;
(j) a variable reflecting the two main municipalities of guava production, equal
to one if the producer is located in the municipalities of Benito Juárez and Jungapeo
(recall that these two municipalities account for most of the guava production, and as
such they are the core of the East region);
(k) two interaction variables, one between region and road and the other
between region and guava area.
The estimation model uses the standard probit model Prob (j=1) = Ф(β ’ x), where Ф
denotes the normal distribution.
27
Table 3 contains the results of the first of these analyses, on determinants of market
channel choice. It can be seen that access to the more modern market (MMM), which is the
dependent variable, is determined only by two variables: first and foremost, by being located
in the two main municipalities in the Eastern zone (Benito Juárez or Jungapeo), and, to a
lesser but still significant extent, by the household’s fixed capital assets. Other important
assets, such as size of the guava orchard (strongly correlated to farm size), level of schooling
of the producer managing the guava farm, membership in a farmers’ organization, or the
interactions between size of guava orchard and region and between region and distance to
paved roads, are not significant. Another important result in Table 3 is that distance from the
farm to a paved road is not significant if one is controlling for region.
The second stage of analysis focuses on two goals: (1) comparing the technical
efficiency of the MMM farmers versus the traditional channel producers; this involves
estimating production functions; (2) comparing the allocative efficiency of the MMM farmers
versus the traditional channel farmers. This involves using the MPP (marginal physical
products) derived from the production function estimates, multiplying them by guava prices
to calculating “Marginal Value Products” (MVP), and then compare them to the factor
prices, and then a la Lau and Yotopoulos (1971) and Carter and Wiebe (1990) to assess
allocation efficiency. We undertake each of these two things in turn.
First, we estimate three production functions, one for the whole sample and one for
each of the two market channel sub-samples (modern and traditional) controlling for the
conditional probability of being in a market channel. Note that the subscript j is used to
indicate the production functions specific to a market channel (modern or traditional), hence
for the whole sample j it is dropped. The model is:
ijijjijjijjjij KlnXlnYln ελββββ ++++=
28
where Yij represents the total guava production measured in kilograms of producer i. jβ is
the vector of parameters estimated that include the constant term, and other parameters that
reflect the effect of Xij and Kij on Yij. Xij is the vector of the following variable factors:
a) Labor, which is the total labor days used in guava production on the farm.
b) Fertilizer is the total cost of fertilizers used per farm (weighting by prices over
types).
c) Chemicals are the total costs of pesticides, herbicides and agro-chemicals used in
guava production per farm (weighting by prices over types).
d) Kij represents the vector of the following fixed factors: Treeage, Region,
Bigmunicipalities, Experience, Quasi-fixed capital and Education, all as defined
above.
e) Density is the farm’s average number of guava trees over guava area.
f) Three dummy variables to control for soil types (clay, sand, silt) are included.
g) ijλ is the inverse mills ratio (IMR) calculated from the first stage used to control
for the producer’s conditional probability of being in a channel (hence not used
when estimated the production function for the whole sample).
h) ijε is the error term.
The Chow test of equality of parameters is rejected for the estimations by market
channel at 1% significance level. Other functional forms did not add explanatory power (such
as the quadratic and translog), as judged by an F Test between the functional forms; hence we
used the Cobb Douglas production function (Debertin, 1993).
The production function estimations are presented in Table 4. The test for technical
efficiency differences over strata in this model involves comparing the intercept term. The
MMM farmers are substantially more efficient. The marginal physical productivity of labor
29
(controlling for physical capital which augments labor) and tree age are also higher among
the MMM farmers, as expected. By contrast, the productivity of density and experience are
higher among the traditional channel growers, as expected, given their relative lack of those.
Finally, an increment of land adds more production among the traditional farmers, suggesting
relative land scarcity.
Second, from the production function parameter estimates results and sample average
we calculate the marginal value product (MVP) per factor of production (Table 5). These
results highlight several important issues. First, with respect to labor, while traditional market
farmers are overusing this factor (MVP is about 60% of the factor price), ‘modern channel’
farmers appear to be facing a substantial labor constraint. Second, both groups of farmers are
over-utilizing fertilizers, but the problem is twice as important in the case of traditional-
market farmers. In the case of other chemical products (mainly pesticides) there is also
significant overuse, and again, the situation is much worse in the case of the farmers selling
to the traditional channel.
4. CONCLUSIONS AND POLICY IMPLICATIONS
The answers to the research questions are rather clear and they are consistent between
the qualitative and the quantitative analyses: (1) access to the more modern market channels
of guava is determined in the first place by the territorial context in which the farm/household
is located. There is a very strong relationship between different market channels, some more
modern than others, and different guava production areas. (2) Controlling for production
zones, fixed capital is a very important determinant of modern market access, while other
important factors such as farm size, education and participation in farmers’ organizations do
not have a significant influence. (3) Education, farm size, membership in a small-farmers
30
organization, and credit, did not affect access to the more modern channel. (4) Access to
more modern market channels results in significant gains in efficiency for these small-scale
farmers, due to higher yields, less use of labor and of chemical inputs, and in general with
significantly lower production costs per unit of land and of labor; that is, farmers in this
market channel show substantial gains in productivity compared to those in the more
traditional channels. (5) As a result of these efficiency gains, small-scale farmers who sell
their guava in the more modern market supply chains, make substantially higher profits and
household incomes.
These results are intimately dependent on the nature of the diffused nature of the
guava supply chains, which are governed by wholesalers operating out of the traditional
Central Markets. The situation probably would have been very different if the guava supply
chains had been highly centralized and directly controlled by supermarkets, as we have seen
in other situations, such as tomato supply chains to supermarkets in Mexico (Cook and
Reardon 2006).
However, even in these diffuse supply networks governed by wholesalers operating
out of traditional markets, we have seen substantial differentiation. The most powerful
wholesalers, serving the more dynamic markets such as supermarkets, source their products
from those regions with better access, high production levels, and a higher density of high
quality product. The less favorable areas are left to be served by small-scale, informal
intermediaries, who lack the capacity to supply the more dynamic and demanding markets.
This significant level of economic and social differentiation has occurred in just eight years
between 1997 and 2005.
An important policy implication of this research is that it is essential that governments
and development agencies understand and internalize in their policies and programs, the
dizzying speed of these processes of market restructuring; we cannot continue to act as if we
31
had unlimited time. Hence, policies need to be proactive and anticipatory. In fact, time is
perhaps the most important constraint in facilitating and supporting the access of small-scale,
resource-poor farmers to the more dynamic restructured national markets.
Another very important policy implication of this strong spatial differentiation of the
opportunities to access more dynamic markets is that development policies and programs
cannot aim solely at their usual two sectoral objectives: (a) improving the quality of supply
chains, or (b) strengthening the capacities of the farmers and their organizations. In addition,
a third dimension, the territorial one, may need to be considered, to link the territory as a
whole to the more dynamic markets.
It is not isolated households or farms that access (or do not access) dynamic national
markets, it is whole rural territories, including the farms within them, but also the small
traders, the truck drivers, the wage laborers, the agricultural input or equipment suppliers, and
so on. An individual small farmer, or even a group of them, may have the required physical,
financial, human, natural and social capital assets, but if they are in areas similar to the
Central region in the case of guava, they are more likely to be bypassed than another group of
farmers with perhaps less of those assets but who are located in areas such as the East region.
The strengthening of the localized networks linking farmers to more dynamic markets
through a maze of informal local brokers, intermediaries, and local wholesalers, should
feature prominently in addressing this territorial dimension of market access and inclusion.
These networks, of course, rely on local institutions to function well (as highlighted by the
fact that the vast majority of the guava farmers in both regions consistently sell, season after
season, through the same local broker or intermediary, citing ‘trust that at least I will receive
the payment’ as the main reason for doing so) and this is another important element to be
addressed as part of this territorial dimension. These ‘soft’ issues tend to be ignored in many
of the prevalent approaches and methods to support market access by smallholders, which
32
tend to focus on technologies, equipment, credit, good managers, and public infrastructure
such as roads or telecommunications. This is because of the strong if not exclusive focus of
these prevalent approaches on the farmers, the farm, and the farmers’ organization.
A third aspect to be addressed as part of this territorial dimension, is the strengthening
of urban-rural links, since the rural hinterland of regions such as the East in Michoacán, link
to major markets through services and service-providers that are localized and rely on
intermediate urban centers (in this case, the city of Zitacuaro, population 75,000).
In the Central region, addressing the territorial dimension this requires putting in place
policies and programs to break the chicken-and-egg problem of having to rely on the small
and very informal intermediaries serving shrinking markets that do not pay for quality, while
at the same time having serious productivity and quality problems at the farm level because
farmers are largely caught in this poor market. Strengthening farmers’ organizations and the
capacities of the small farmers at the farm level, will lead nowhere unless they take place in
the context of programs that aim at stimulating a more positive cycle of better markets -
better intermediaries, brokers and wholesalers – better quality and higher productivity at the
farm level. We ask ourselves if building and equipping warehouses for the farmers
organizations in the Central region, in the absence of a better market channel, will do much
good. Perhaps the key that can unlock the stalemate, is to attract a few of the larger
wholesalers for a sufficiently large period of time, through the targeted and temporary use of
part of the $ 2 million that the government is already spending in the guava region; a
combination of investment in road improvement, simple collection centers in strategic places,
effective technical advisory services, and direct subsidies to farmers and to wholesalers to
improve their links, could possibly aid in this regard8.
On the other hand, the Eastern production region as a whole also has strategic choices
to make if it is going to sustain its rapid development. To link to even better markets, some
33
“regional public goods” are necessary, and by far the main one is achieving the phytosanitary
standard (free of fruit fly) that will allow it to link, as a region, into the more profitable
markets in the Northern states and even for export. There are programs in place to this end,
but they are hampered by the weaknesses of the farmers’ organizations in the East region of
Michoacán, which find it difficult to be effective in coordinating collective action among
their members.
A final point has to do with that sacred totem of market access programs: the Small
Farmers’ Organization (SFOs). We have seen that both guava regions are swarming with
SFOs promoted by a number of development agencies. Literally millions of dollars have been
invested in these SFOs (heavily subsidized by donors, NGOs, and government) to equip them
with machinery, trucks, rotating credit funds, advisors, managers, and just every other kind of
asset one could think of. The vast majority of the farmers declare that they are members of
one or more of these organizations. And yet, both the household survey data and the results of
the rapid rural appraisal, very clearly show that these SFOs played no role in facilitating
access of their members to the more-modern markets. And yet, we have also concluded that
is not isolated small-scale farmers who relying on their own individual efforts manage to
reach these markets. What we have found is collective action organized in manners which
have little to do with the traditional SFO model that in one way or another attempts to
replicate the model of the cooperatives in the developed world. What we find is that market
access in fact is promoted and mediated by collective action organized in the form not of
SFOs but of localized networks, that include individual farmers or informal groups of farmers
that live in the same village or the same ejido, and even a few more effective SFOs (of the
“new generation cooperative” type that have a limited membership and focused objectives),
but also the much-hated coyotes (intermediaries), fleteros (informal local brokers), local
wholesalers, agricultural advisors, traditional leaders of the ejidos and other community
34
organizations, and a myriad other social and economic agents. Our development theory says
that these complex networks need to be replaced by modern-looking SFOs; we conclude and
propose that this is a premise that surely needs some careful rethinking.

NOTES
1 An important question, not covered in this study, is whether in countries with very high levels of income inequality, such as Mexico, the dynamics of the rise of supermarkets will eventually lead to a dual system of food distribution, with one branch serving the poor and, another one the middle classes and the rich. An alternative hypothesis is that supermarkets will develop differentiated formats to provide universal coverage. 2 Planet Retail, 10 February 2006 (http://www.planetretail.net/) 3 It is worth noting Krugman’s (1995, p. 92) conclusion that “... cumulative causation suggests that initial advantages due to historical accident [our emphasis] may play a major role in explaining the pattern of location.” This is clearly the case with the 1997 frost in Aguascalientes that displaced guava production towards Michoacán. The question is how can one deal with such historical accidents when trying to design normative public policies? 4 It should also be noted that in the East there is a history going back at least 40 years of diversification and reconversion to adjust to changes in markets, policies, pest and diseases and other factors. 5 The French chain Carrefour, whose Mexican stores have been very recently sold to the domestic chain Chedraui, used to operate in a similar manner but now they work directly out of the Distribution Center in San Luis Obispo, near Mexico City. 6 We observed in Michoacán two instances of mechanized guava sorting and packaging, using adapted machinery originally used in avocado, the main agricultural product of the state. One of these two machines is owned and operated by PROGOMICH, a small farmers’ organization. The expansion of these services in the production areas, could in the future facilitate more direct relations between supermarkets and producers. 7 This includes hired as well as own-family labor. 8 Chile’s “Supplier Development Program” (PDP is the acronym in Spanish) is an example of how these direct subsidies could be provided in a way which is consistent with a market approach. This program subsidizes the costs of a coherent set of systematic actions (technology transfer, training, coordination costs, and so on) that are part of a comprehensive plan to develop or improve the links between a group of small and medium suppliers and a downstream firm such as an agri-processor or an exporter.
