Abstract

In low- and middle-income countries, poor cooperation between members of smallholder agricultural households may lead to inefficient allocation of productive resources. This study estimates the causal mediating effects of cooperation between spouses on household welfare and public goods provision in Ugandan and Tanzanian monogamous smallholder coffee farming households. The random encouragement to participate in an intensive training program coaching couples in farming as a household enterprise and participatory intrahousehold decision making, which stimulates cooperation and, in turn, household welfare and public goods provision, enables estimating causal mediating effects while avoiding challenges of endogeneity. Spousal cooperation has positive mediating effects on household welfare, measured by total household income per capita and food security, and on household public goods provision, measured by the adoption intensity of agronomic practices and use of improved seed for food crops. Spousal cooperation has larger effects on total household income per capita with longer duration of marriage. HIGHLIGHTS In Uganda and Tanzania, the Gender Household Approach program aims to improve gender relations by promoting spousal cooperation. Participatory decision making implies strengthening women’s voice and ability to include their claims in a household. GHA presents a concept of women’s empowerment that avoids backlash by promoting shared control of resources and agency. Programs that promote spousal cooperation can improve the welfare and public goods provision of agricultural households.
