• Development discourse and praxis focus on ‘opportunities’
• Why do the poor not ‘invest’? – Ethiopians and fatalism?
• A variety of mostly complementary explanations have been forwarded over the years. – Low returns to investments – Example: no schools, lack of credit
(market failures); – Unexploited opportunities due to lack of information/knowledge
about the opportunities/returns – Example: insufficient observable cases;
– Social constraints dampen the economic attractiveness of investment opportunities – Example: egalitarian norms, very high taxation, excessive regulations’
Motivation – why aspirations

• Focus - ‘external circumstances’ and ‘opportunities’,
• Shift in focus - constraints associated with the manifested attributes of decision makers– Identity issues: People’s choices are conditioned by their
sense of self – Example: stereotype roles;– Psychological issues: impatience, commitment, and
psychological barriers and similar reasons identified by the behavioural economics literature – Example: loss aversion and the consequent preference for the status quo;
Motivation – why aspirations

Motivation – why aspirations
• the aspirations failure approach:
– attempts to blend external constraints that the poor face with the potential effect these constraints may have on the internal logic governing choice by them;
– affords an alternative characterisation of what appears to be fatalism (Ethiopia)

Elements of the Aspirations Perspective
What are aspirations? Aspirations have two distinctive features:• Future-oriented - are goals that can only be satisfied at some
future time (differ from immediate gratifications);• Motivators - are goals individuals are willing, in principle, to
invest time, effort or money in to attain (different from idle daydreams and wishes)
Note: the ‘willingness to invest’ is ‘potential’, or ‘conditional’ Ref: Simon (1977), Selten (1999), Appadurai (2002), Ray (2003)
Elements of the Aspirations Perspective
Why are aspirations important/useful?
Aspirations (or the capacity to aspire): • Reflect bounded rationality;• Are socially determined (social interaction); • Are distributed unevenly within communities.
– Condition individual behaviour and well-being– Useful device in analysing and/or addressing poverty

Framework
13/04/23 7
Wealth Aspiration - DataRound 7 Question: We would now like you to think of your own wealth. Thinking of a scale from 1 (the lowest or worst level) to 10 (the highest or best level):
Q39a. At what level do you believe you are currently?
Q39b. At what level would you like to be?
Estimation
•Use responses to Q39b as the dependent variable;
•Responses to the wealth aspiration question are ordered –
– ordered probit model;
– Generalized ordered probit model
– Semi-nonparametric estimation of extended ordered probit model
•Clustered standard errors

Data - ERHS Survey Rounds
• Spatial coverage: 15 Kebeles (villages);
• Temporal coverage: 1993/94-2008/9 (7 rounds the last three roughly one every 5 years)

Variables – All survey roundsWealth Aspiration
Level of wealth the respondent would like to achieve (measured using a 10-point scale)
Age Respondent's age in number of yearsAge squared Respondent's age in number of years (squared)Gender (male=1) Gender of respondent
Non-farm activities (yes=1) Dummy - the respondent engages in non-farm activities (Yes=1)
Iddir (member=1)Dummy - the respondent is a member of an Iddir (funeral association) (Member=1)
Married (yes=1) Marital status of the respondent (married=1)
ShocksShock faced by respondent in the last 5 years - index calculated using principal components
Neighbourhood sizeNumber of neighbours within a radius of 500m from the respondent's residence
Average income growth of neighbours (round7-round6)
Average growth in the real consumption per capita (in 1994 prices) of the respondent's neighbours between Rounds 6 and 7 (%).
Income growth (round 2 - round 1) - Income growth (round 7 - round 6)
Growth in the real consumption per capita (in 1994 prices) of the respondent's household between successive survey Rounds (%)
PoorNumber of rounds the respondent's family was classified as poor (using the poverty line in 1994)

Observations
Poorer individuals seem to have lower aspirations;
Correlations but note that most of the relevant variables lagged;
Results persist across models;
Encouraging result since data not designed for the purpose;

Elements of the Aspirations PerspectiveMeasurement Issues
• Aspirations are not directly observable
– Revealed by observed behaviour: interpretation issues (linking aspirations and behaviour)
– Elicited using subjective questions: measurement issues
• Limits to subjective assessment:
– subjects’ willingness to report private knowledge, evaluation apprehension, and subject role playing
– attributes of the instrument used: prior questions (anchoring), the number of categories on the rating scale, the adjectives that are used as the endpoints of the rating scale, and the adverbs that describe scale categories.
(e.g. Delavande et al. (2009), Bertrand and Mullainathan (2001) for some reviews)

Elements of the Aspirations Perspective
Identification issues
• individual characteristics affect aspirations, aspiration windows and behaviour (e.g. schooling levels, wealth, and family background),
Particularly the endogeneity of the aspiration window a key hurdle
• Investment ‘cause’ aspirations (e.g. the successful investor may in turn revise his/her aspiration to a higher level), or
• aspirations ‘cause’ investment – the one we aim to identify.
An experimental design helpful to test the link between aspiration window, aspirations and aspirations failures.

Aspiration formation – A simple formulation
Central Proposition: ((Bandura (1993, 1994) in psychology, Appadurai (2001) in sociology , Ray (2006) in economics):
Aspirations reflect: an individual’s aspiration window – peers and economic
opportunities of the local environment An individual’s own characteristics and past experience including
shocks;
