This paper uses Generational Accounting to assess the fiscal impacts of Korean reunification. Our findings suggest that early reunification will result in a large increase in the fiscal burden for most current and future generations of South Koreans. The Korean reunification's fiscal impact...

Does foreign military assistance strengthen or further weaken fragile states facing internal conflict? Aid may strengthen the state by bolstering its repressive capacity vis-à-vis armed non-state actors, or weaken it if resources are diverted to these very groups. We examine how U.S. military...

Illegal arms are responsible for thousands of deaths in civil wars every year. Yet, their trade is very hard to detect. We propose a method to statistically detect illegal arms trade based on the investor knowledge embedded in financial markets. We focus on eight countries under UN arms embargo...

We attempt to make inferences about the elasticity of the government's demand for specific weapons by analyzing the statistical relationship between quantity and cost revisions across the population of major weapon systems, using data contained in the Pentagon's Selected Acquisition Reports. The...

The proposition that widespread gun ownership serves as a deterrent to residential burglary is widely touted by advocates, but the evidence is weak, consisting of anecdotes, interviews with burglars, casual comparisons with other countries, and the like. A more systematic exploration requires...

John Lott and David Mustard have used regression analysis to argue forcefully that 'shall-issue' laws (which give citizens an unimpeded right to secure permits for concealed weapons) reduce violent crime. While certain facially plausible statistical models appear to generate this conclusion,...

We explore the role of ruling elites in autocratic regimes and provide an assessment of tools useful to clarify the structure of opaque political environments. We first showcase the importance of analyzing autocratic regimes as non-unitary actors by discussing extant work on nondemocracies in...

Using a variance decomposition of shocks to GDP, we quantify the role of international factor income, international transfers, and saving in achieving risk sharing during the recent European crisis. We focus on the sub-periods 1990-2007, 2008-2009, and 2010 and consider separately the European...

This paper studies the effect of foreign aid on economic stabilization. Following Alesina and Drazen (1991), we model the delay in stabilizing as the result of a distributional struggle: reforms are postponed because they are costly and each distributional faction hopes to reduce its share of...

Following the rationale for regional redistribution programs described in the official documents of the European Union, this paper studies a very simple multi-country model built around two regions: a core and a periphery. Technological spill-overs link firms' productivity in each of the two...
