Does sharing the same religion, civilization or racial proximity lead to more peaceful relations between countries? This paper argues that cultural similarity can actually cause wars, which occur to combat diffusion. This new theory of war combines the models of Acemoglu and Robinson (2006) and...

We study escalation and aggression in an experimental first-strike game in which two participants play multiple rounds of a money-earning task. In each round, both players can spend money to accumulate weapons. The player with more weapons can spend money to strike against the other player,...

Capitalizing on the latest developments in the gravity literature, we utilize two new datasets on sanctions and trade to study the impact of economic sanctions on international trade in the mining sector, which includes oil and natural gas. We demonstrate that the gravity equation is well suited...

The rise of a new power may lead the dominant power to seek a preventive war. We study this scenario in an experimental two-stage bargaining game. In each stage, the rising power makes a bargaining offer and the declining power must choose whether to accept it or fight. Between the two stages,...

The World Trade Organization (WTO) as an institution accords much less of a role to its chief officer and her staff, namely the WTO Director-General and the Secretariat, than do any of its sister international organizations—the World Bank, the International Monetary Fund, the Organization for...
