This paper highlights the importance of natural resource concentration and ethnic group regional concentration for ethnic conflict. A new type of bargaining failure due to multiple types of potential conflicts (and hence multiple threat points) is identified. The theory predicts war to be more...

Understanding and minimizing the transaction costs of policy implementation are critical for reducing tropical forest losses. As the international community prepares to launch REDD+, a global initiative to reduce greenhouse gas emissions from tropical deforestation, policymakers need to pay...

Contract enforcement is probabilistic, but the probability depends on rules and processes. A stimulus to trade may induce traders to alter rules or processes to improve enforcement. In the model of this paper, such a positive knock-on effect occurs when the elasticity of supply of traders is...

In this paper I discuss the effectiveness of foreign aid from a historical perspective. I show that foreign aid is a relatively new concept in economics, and I emphasize the role of exchange rate policies in the foreign aid controversies of the 1970s through 1990s. I show that in the early 1980s...

Tenancy has been a means for labor to advance their socio-economic condition in agriculture yet in Brazil and Latin America, tenancy rates are low compared to the U.S. and the OECD countries. We test for the importance of insecure property rights in Brazil on the reluctance of landowners to rent...

We estimate the general-equilibrium labor market effects of a large-scale randomized intervention in which we designed and marketed a rainfall index insurance product across three states in India. Marketing agricultural insurance to both cultivators and to agricultural wage laborers allows us to...

Political institutions can affect corruption. We use audit reports from an anti-corruption program in Brazil to construct new measures of political corruption in local governments and test whether electoral accountability affects the corruption practices of incumbent politicians. We find...

Autocrats in many developing countries have extracted enormous personal rents from power. In addition, they have imposed inefficient policies including pervasive patronage spending. I present a model in which the presence of ethnic identities and the absence of institutionalized succession...

We present a conceptual framework to better understand the interaction between settlement and the emergence of de facto property rights on frontiers prior to governments establishing and enforcing de jure property rights. In this framework, potential rents associated with more exclusivity drives...

We estimate the effect of local media outlets on political accountability in Mexico, focusing on malfeasance by municipal mayors. We study federal grants earmarked for infrastructure projects targeting the poor, and leverage two sources of plausibly exogenous variation. First, we exploit...
