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...

This paper presents a political economy model where there is mutual feedback between investor protection and stock market development. Better investor protection induces companies to issue more equity and thereby leads to a broader stock market. In turn, equity issuance expands the shareholder...

The regulations that shape the design and the operations of corporations, credit and securities markets differ vastly from country to country. In addition, similar regulations are often unequally enforced in different countries. Economists still have an imperfect understanding of why these...

We review current methods for calculating fines against cartels in the US and EU, and simulate their deterrence effects under different assumptions on the legal and economic environment. It is likely that European fines have not had significant deterrence effects before leniency programs were...

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...

I develop a model of ideologies as collectively sustained (yet individually rational) distortions in beliefs concerning the proper scope of governments versus markets. In processing and interpreting signals of the efficacy of public and market provision of education, health insurance, pensions,...

During the period from 1880 to 1950 publicly managed retirement security programs became an important part of the social fabric in most advanced economies. In this paper we study the social, demographic and economic origins of social security. We describe a model economy in which demographics,...

We analyse how, in representative democracies, income distribution influences the stringency of environmental policy and economic growth. Individuals (who differ in abilities) live for two periods, working when young and owning capital when old. Externalities are caused by a polluting factor....

We analyse general equilibrium relationships between trade policy and the household distribution of income, decomposing social welfare into real income level and variance components through Gini and Atkinson indexes. We embed these inequality-adjusted social welfare functions in a general...

We study political activism by several agents (lobbyists, unions, etc.) who have private but imperfect policy-relevant signals, and seek to influence the decisions of a policy maker. When agents can share information and coordinate their actions, the equilibrium is shown to be equivalent to that...
