Despite the large and growing number of humanitarian emergencies, there is very little economic research on the impact of refugees and internally displaced people on the communities that receive them. This paper analyzes the impact of the refugee inflows from Burundi and Rwanda in 1993 and 1994...

In this paper we present a continuous time optimal control analysis of resistance buildup in agricultural chemicals when the supplier is a monopolist. We solve a general model and examine the solutions for Cobb-Douglas demand, including a simulation of changes in the interest rate and pest...

Cost-effective allocation of conditional cash transfers (CCT) requires identifying recipients with low opportunity costs who might change behavior. This paper develops a low-cost approach for improving program implementation by using a stated preference, referendum-style survey question to...

Environmental conditional cash transfers, or "payments for ecosystem services" are a centerpiece of global efforts to protect biodiversity, safeguard watersheds, and mitigate climate change by reducing forest loss. This paper evaluates the impacts of Mexico's national payments for ecosystem...

Every year between 2000 and 2010, our planet lost native forests roughly the size of Costa Rica. (FAO, 2010). This rapid deforestation has dramatically changed the chemical composition of the world's atmosphere, the level of biodiversity, and the presence of vegetation key to maintaining...

Despite the large and growing number of humanitarian emergencies, there is little economic research on the impact of refugees and internally displaced people on the communities that receive them. This analysis of the impact of the refugee inflows from Burundi and Rwanda in 1993 and 1994 on host...

We study the consequences of poverty alleviation programs for environmental degradation in Mexico. We exploit the community-level eligibility discontinuity for a conditional cash transfer program to identify the impacts of income increases on deforestation, and use the program’s initial...

This paper develops and tests a theory of common property deforestation over space. The model examines both the spatial distribution of forest loss and the total amount of deforestation within a given community, showing how these outcomes are jointly determined. We estimate the equations of the...

Deforestation policies in Mexico need to recognize heterogeneity in communitys' management schemes. In communities that extract wood from the forest for profit, forestry projects generate funds whose investment in public goods increases the value of standing forest to those not receiving direct...
