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...

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...

A relatively obscure defense procurement policy establishes a large subsidy to private military R&D investment. On the surface, it appears that the marginal subsidy to such investment is zero, but this is only true in the short run. Due to DOD's policy of allowable-cost determination, the...

In the US and many other OECD countries, expenditures for defense-related R&D represent a key policy channel through which governments shape innovation, and dwarf all other public subsidies for innovation. We examine the impact of government funding for R&D - and defense-related R&D in...

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...

When investing in research and development (R&D), institutions must decide whether to take a top-down approach -- soliciting a particular technology -- or a bottom-up approach in which innovators suggest ideas. This paper examines a reform to the U.S. Air Force Small Business Innovation Research...

Water suppliers are showing greater interest in using different mechanisms to promote conservation. One such mechanism is conducting home water audits, which involves assessing water use and providing tailored suggestions for conserving water for residential customers. Yet, very little is known...

Although fake online customer reviews have become prevalent on platforms such as Amazon, Google, and Facebook, little is known about how these reviews influence consumer behavior. This paper provides the first experimental estimates of the effects of fake reviews on individual demand and...
