We study whether leaders influence the unethical conduct of followers. To avoid selection issues present in natural environments, we use a laboratory experiment in which we form groups and assign leadership roles at random. We study an environment in which groups compete, with dishonest behavior...

This paper scrutinizes the effects of investor-state dispute settlements (ISDS) and national treatment provisions in a two-period model where foreign investment is subject to domestic regulation and a holdup problem. It shows that ISDS can mitigate the holdup problem and increases aggregate...

We build a heterogeneous-firms model with firm-specific wages and credit frictions to study the role of financial development for inequality in the global economy. If there are many small firms, better access to external funds reduces wage inequality and unemployment. In contrast, if there are...

How valuable are long-term supplier relationships? To address this question, this paper explores relationships between U.S. importers and their suppliers abroad. We first establish several facts: almost half of U.S. imports are in relationships three years or older, relationship survival and...

The efficiency effects of carbon pricing depend on how it impacts distortions in fossil fuel markets, most notably from local air pollution externalities. By offsetting these distortions, carbon pricing may generate significant net economic benefits, so it is in countries own interests to...

The traditional school of economic policy analysis predicts that globalisation will give rise to predatory competition between the governments of the European nation states. The consequence is anticipated to be a marked reduction in, if not the destruction of, the benevolent Welfare State. The...

The US decision not to ratify the Kyoto Protocol and the recent outcomes of the Bonn and Marrakech Conferences of the Parties drastically reduces the effectiveness of the Kyoto Protocol in controlling GHG emissions. The reason is not only the reduced emission abatement in the US, but also the...

This paper assesses the role of a larger degree of common language use between the populations of two countries on the so-called extensive product margin of trade. We focus on the overlap of products exported or imported between any pair of countries. The results suggest that the effect of...

We develop a simple structural model of value added tax (VAT) compliance, and estimate it using widely available national accounts data to learn about compliance in countries where little is currently known. International border controls improve VAT compliance, generating a correlation between...
