Problem statement Rural households in Niger remain heavily dependent
on agriculture for their livelihoods Women play a critical and potentially transformative
role in agricultural and rural sector growth but face persistent obstacles and economic constraints limiting further inclusion in agriculture and rural development
Arguably, these obstacles are particularly pronounced in primary households headed by a female
The Women’s Empowerment in Agriculture Index (WEAI) is a survey-based index designed to measure the empowerment, agency and inclusion of women in the agricultural sector
Here, we consider the WEAI as a human capital variable and assess the role of the state of empowerment in agriculture

Background Human capital refers to any aspect of a person that
produces economic value and from which one cannot be separated the way one can be from physical or financial assets (Becker, 1975)
The role of human capital as an engine of agricultural growth has been given due attention in the literature
Increases in output beyond increases in land, man-hours and physical reproducible capital have been attributed to investment in human capital (Schultz 1961)
In the field of microeconomics, role of human capital assessed by estimating a production function with human capital variables entering linearly as additional inputs

Background Two problems with this approach:
1. There may be nonlinearities in the production-human capital relationship
2. Environmental variables, such as human capital variables, not only affect the location of a household on a given production function but also determine the choice of the implemented technique so that the assumption of constant coefficients on traditional inputs may be invalid

Data Women’s Empowerment in Agriculture Index
(WEAI) and agricultural household surveys used to collect data in 500 households in three communes (Dogueraoua, Malbaza and Tsernaoua) in the Tahoua region of Niger during April-May 2015
Villages randomly selected using probability proportional to size sampling while households were randomly selected using the quota method.

Setting Three-fourths of Niger is covered by the Sahara
desert The rainy season lasts only three months, with
total rainfall of 150–600 mm per year Maximum temperatures are high (45 degrees
Celsius in the shade in April–May) Livestock production is a major component of
farming Millet is the most important staple crop,
occupying nearly half of the total harvested area in the country
No land market Traditional production practices with little
external inputs Cultivation largely rain-fed

Estimation strategy1. IV methods to identify fertilizer use,
labor input and empowerment • household composition variables • number of plots cultivated • time to paved road • time to nearest potable water source • distance to nearest potable water source• number of months village is accessible
2. Li and Wang (1998) generalized consistent conditional model test for functional form selection

Results: non linearities
• The relationship between empowerment and agricultural production is nonlinear and rather concave
• Although flat for values of disempowerment of up to 0.30 as individuals become increasingly disempowered, returns become consistently negative

Results: interaction effects Empowerment is technology changing Disempowerment interacts positively with
returns to land and fertilizer and negatively with returns to labor and equipment
Disempowerment hampers returns to labor and, to a lesser extent, equipment
Given, for example, the important contribution of group membership to empowerment, increased group membership through its effect on empowerment would enhance the efficiency with which labor is applied and equipment is used

Results Increased formal education is associated
with a deterioration in output Returns to empowerment differ across
households groups and are much higher for primary female headed households and lower for primary male headed households
Relatively higher disempowerment in female headed primary households strongly affects returns to their labor input and equipment use

Conclusions and policy recommendations
Female headed household less empowered
Contributors are autonomy and control over use of income, group membership and speaking in public
Empowerment is technology changing: different production functions for different households depending on the level of empowerment
Less empowered female headed households generate lower returns from labor and equipment
….and produce consistently less
