- W2588204014 abstract "This dissertation is composed of three essays; the first two examine the decisionmaking of potato producing households in Bolivia and the third examines well-being changes among Zimbabwe households. The first essay entitled “The role of risk mitigation in production efficiency: A case study of potato cultivation in the Bolivian Andes” estimates the costs of self-managing environmental risk through activity and environmental diversification. Risk management has the potential to reduce income variability but at the cost of increasing production inefficiency, which we measure employing a stochastic production frontier. Among variables capturing environmental diversification, discontinuity between fields has the most detrimental effect on production efficiency. Activity diversification, measured by the ratio of potato to total crop revenue, has a stronger impact on inefficiency and yield losses than any of the environmental diversification variables. The second essay entitled “Determinants of market participation decisions and marketing choices in Bolivia” examines three decisions related to potato market participation: market entry, volume sold, and market choice. The first two are analyzed using a Heckman selection model. Results indicate that isolation, measured by population density and distance to markets, negatively impacts market entry. The most important determinant of quantity sold is land holding. Market choices are judged according to second-order stochastic dominance (SOSD). Market choices meeting the SOSD criterion" @default.
