"Empirical studies of the relationship between school inputs and test scores typically do not account for the fact that households will respond to changes in school inputs. We present a dynamic household optimization model relating test scores to school and household inputs, and test its...

"This paper investigates the impacts of cotton marketing reforms on farm productivity, a key element for poverty alleviation, in rural Zambia. The reforms comprised the elimination of the Zambian cotton marketing board that was in place since 1977. Following liberalization, the sector adopted an...

We use the prices of credit card asset-backed securities to study the market risk premium associated with unsecured consumer credit risk. The consumer credit risk premium has historically been comparable to high yield corporate bond spreads, but has increased dramatically since the financial...

Since 2003, Zambia has been engaged in a large-scale, centrally coordinated national anti-Malaria campaign which has become a model in sub-Saharan Africa. This paper aims at quantifying the individual and macro level benefits of this campaign, which involved mass distribution of insecticide...

The controversy over whether and how much to charge for health products in the developing world rests, in part, on whether higher prices can increase use, either by targeting distribution to high-use households (a screening effect), or by stimulating use psychologically through a sunk-cost...

Many rural households in low and middle income countries continue to rely on small-scale agriculture as their primary source of income. In the absence of irrigation, income arrives only once or twice per year, and has to cover consumption and input needs until the subsequent harvest. We develop...

Water use and electricity use, which generate negative environmental externalities, are susceptible to a second externality problem: with household-level billing, each person enjoys private benefits of consumption but shares the cost with other household members. If individual usage is...
