The field of international trade has undergone significant theoretical and empirical advancements over the last twenty-five years. A key breakthrough has been the emergence of firm-level approaches to studying exporting, importing, and global value chains. The field has also experienced a...

This paper analyzes whether the propensity to secede by subnational regions responds mostly to differences in income per capita or to distinct identities. We explore this question in a quantitative political economy model where people's willingness to finance a public good depends on their...

A simple dynamic game is used for analyzing international environmental problems and climate agreements. Different countries are, over time, emitting as well as investing in green technology. In this framework, we can analyze the business-as-usual outcome, short vs. long term agreements,...

Until the beginning of this century, the GATT/WTO system worked. Economic research provided a compelling explanation. It showed that if governments maximize the well-being of their own countries broadly defined, GATT/WTO principles would facilitate mutually beneficial cooperation over their...

We study how international agreements can take advantage of domestic time-inconsistency problems in the context of environmental policies. For example, policymakers will prefer future policies to be sustainable, but find it tempting to raise consumption when being in office. We find the...

Job security provisions are commonly invoked to explain the high and persistent European unemployment rates. This belief has led several countries to reform their labor markets and liberalize the use of fixed-term contracts. Despite how common such contracts have become after deregulation, there...

The debate over the influence of labour market flexibility on performance is unlikely to be settled by additional studies using aggregate data and making cross-country comparisons. While this approach holds little promise, micro-analysis of workers and firms and increased use of experimental...

Job security provisions are widely believed to reduce dismissals and hiring. In addition, in developing countries job security is believed to reduce compliance with labor regulations and to increase informal activity. Reductions in dismissal costs are, thus, often advocated as a way to increase...

We investigate the regulation of labor markets through employment laws, collective bargaining laws, and social security laws in 85 countries. We find that richer countries regulate labor less than poorer countries do, although they have more generous social security systems. The political power...

We study the gains from increased wage flexibility using a small open economy model with staggered price and wage setting. Two results stand out: (i) the effectiveness of labor cost reductions as a means to stimulate employment is much smaller in a currency union, (ii) an increase in wage...
