We analyze optimal contracts and optimal matching patterns in a simple model of partnership where there is a double-sided moral hazard problem and potential partners differ in their productivity in two tasks. It is possible for one individual to accomplish both tasks (sole production) and there...

Though models of political economy suggest that changes in political institutions, such as democratization, should have large effects on policies and economic outcomes, the empirical literature finds ambiguous results. It is important, however, to ‘unbundle’ democratic reforms into more...

We model residential land use constraints as the outcome of a political economy game between owners of developed and owners of undeveloped land. Land use constraints benefit the former group via increasing property prices but hurt the latter via increasing development costs. In this setting,...

This paper studies the effect of landownership concentration on school enrollment for nineteenth century Prussia. Prussia is an interesting laboratory given its decentralized educational system and the presence of heterogeneous agricultural institutions. We find that landownership concentration,...

We model residential land use constraints as the outcome of a political economy game between owners of developed and owners of undeveloped land. Land use constraints benefit the former group (via increasing property prices) but hurt the latter (via increasing development costs). More desirable...

Tropical deforestation accounts for almost one-fifth of greenhouse gas emissions worldwide and threatens the world's most diverse ecosystems. The prevalence of illegal forest extraction in the tropics suggests that understanding the incentives of local bureaucrats and politicians who enforce...

Unilateral second-best carbon taxes are analysed in a two-period, two-country model with international trade in final goods, oil and bonds. Acceleration of global warming resulting from a future carbon tax is large if the price elasticities of oil demand are large and that of oil supply is...

We suggest a development-compatible refunding system designed to mitigate climate change. Industrial countries pay an initial fee into a global fund. Each country chooses its national carbon tax. Part of the global fund is refunded to developing and industrial countries, in proportion to the...

We derive conditions of individual preferences and technology that give rise to a negative correlation between income inequality and environmental protection. We present a class of models (which captures a static model as well as an overlapping-generations model) in which individuals differ in...
