We study the relationship between market structure and public procurement outcomes. In particular, we ask whether and to what extent consolidation-driven increases in industry concentration affect the way in which the government procures its goods and services. We focus on the defense industry,...

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 study the geographic distribution of military supply contracts during World War II. This is a unique case, since over $3 trillion current day dollars was spent, and there were concerns that the country's future hinged on the war outcome. We find robust evidence consistent with the hypothesis...

Official government statistics on the "mission-distribution" ofU.S. R&D investment are based on the assumption that only the governmentsponsors military R&D. In this paper we advance and test thealternative hypothesis, that a significant share of privately-financedindustrial R&D is military in...

U.S. manufacturing firms that make sophisticated weapons systems for the Pentagon are subject to an unusual regulatory regime that obligates them to volunteer' information on their business practices to the government and to prime contractors as a condition of their special relationship with the...

There is little econometric study of how governments should procure innovation. One choice facing policymakers is whether to tightly specify the innovations they seek (a “Conventional” approach) or to allow firms to suggest ideas (an “Open” approach). We exploit a natural experiment in...

This paper tests the differential effects of the generosity of the welfare state under free migration and under policy-controlled migration, distinguishing between source developing and developed countries. We utilize free-movement within the EU to examine the free migration regime and compare...

This paper models and estimates ex ante safety-net benefits at a sample of large banks in US and Europe during 2003-2008. Our results suggest that difficult-to-fail and unwind (DFU) banks enjoyed substantially higher ex ante benefits than other institutions. Safety-net benefits prove...

We examine the capital-market effects of changes in securities regulation in the European Union (EU) aimed at reducing market abuse and increasing transparency. To estimate causal effects for the population of EU firms, we exploit that for plausibly exogenous reasons, like national legislative...

This paper estimates, using data from the United States and Euro Area, a two-country stochastic growth model in which both neutral and investment-specific technology shocks are nonstationary but cointegrated across economies. The results point to large and persistent swings in productivity, both...
