We conducted a laboratory experiment to test the comparative statics predictions of a new approach to collective action games based on the method of stability sets. We find robust support for the main theoretical predictions. As we increase the payoff of a successful collective action (accruing...

The potential benefits of demand side interventions may leak into the profits of suppliers whenever there is market power. In those situations, governments could attempt to regulate the market or to increase competition. We provide the first experimental evidence on the effect of increased...

We exploit three natural experiments in Argentina in order to study the role of legislative malapportionment on the biased federal tax sharing scheme prevalent in the country. We do not find support to attribute it to legislative malapportionment during periods when democratic governments were...

The creation of non-contributory pension schemes is becoming increasingly common as countries struggle to reduce poverty. Drawing on data from Mexico's Adultos Mayores Program (Older Adults Program) - a cash transfer scheme aimed at rural adults over 70 years of age - we evaluate the effects of...

This paper provides empirical evidence on the causal effects that upgrading slum dwellings has on the living conditions of the extremely poor. In particular, we study the impact of providing better houses in situ to slum dwellers in El Salvador, Mexico and Uruguay. We experimentally evaluate the...

This paper develops a politico-economic model for use in studying the role of intra-elite conflict in the simultaneous determination of a country's political regime, trade policy and income-tax-based redistribution scheme. Three socioeconomic groups are involved: two elite groups and workers,...

Argentina privatized most public utilities during the 1990's but re-nationalized the main water company in 2006. We study beliefs about the benefits of the privatization of water services amongst low and middle income groups immediately after the 2006 nationalization. Negative opinions about the...

We document the rise in unemployment in South Africa since the transition in 1994. We describe the likely causes of this increase and analyze whether the increase in unemployment is due to structural changes in the economy (resulting in a new equilibrium unemployment rate) or to negative shocks...

We explore the political economy of trade and migration policies in several models of international trade. We show that in a Ricardian world, free trade and no international labor mobility is a Nash equilibrium outcome, but free trade and free international labor mobility is not. The result...

In response to the preventable threats posed by poor sanitation and hygiene, the Water and Sanitation Program (WSP) launched two large-scale projects, global scaling up handwashing and global scaling up rural sanitation, to improve the health and welfare outcomes for millions of poor people....
