| Using longitudinal survey data from western Kenya, this paper estimates the economic impacts of antiretroviral treatment. The responses in two important outcomes are studied: (1) labor supply of adult AIDS patients receiving treatment; and (2) labor supply of patients household members. We find that within six months after treatment initiation, there is a 20 percent increase in patients likelihood of participating in the labor force and a 35 percent increase in weekly hours worked. Since patient health would continue to decline without treatment, these labor supply responses are underestimates of the impact of treatment on the treated. The upper bound of the treatment impact, based on plausible assumptions about the counterfactual, is considerably... |

| We examine the impact of ambiguous and contested land rights on investment and productivity in agricultural in Akwapim, Ghana. We show that individuals who hold powerful positions in a local political hierarchy have more secure tenure rights, and that as a consequence they invest more in land fertility and have substantially higher output. The intensity of investments on different plots cultivated by a given individual correspond to that individual's security of tenure over those specific plots, and in turn to the individual's position in the political hierarchy relevant to those specific plots. We interpret these results in the context of a simple model of the political allocation of land rights in local matrilineages. |
