The second paper examines the interaction between public investments, community health, and productivity- and land-enhancing technology adoption decisions by farm households in Northern Ethiopia. It models technology adoption as a sequential process where the timing of choices can matter. The econometric test results indicate that the decision and intensity of technology adoption are highly correlated with the sequential nature of adoption. The most striking results concern the importance of disease - the amount of time spent sick and time spent caring for sick family members are inversely associated with both the decision and intensity of technology adoption.
Finally the third paper looks at the welfare impacts of a public water resource development project with health side effects in Tigray, Northern Ethiopia. It uses a model of a social planner to characterize the optimal implementation of such projects over time, showing how health and production are important considerations in this decision. The empirical analysis shows that the marginal net benefits of Tigray's current microdam investments are positive. The lost income households suffer from increased time away from productive activities (due to sickness) is compensated for by increased yields and market opportunities brought about through irrigated agriculture. However, it should be noted that this conclusion is based on efficiency and not equity.
