Over the last thirty years, the United States has entered into nearly fifty Bilateral Investment Treaties (BITs). A foundational question that has not yet been adequately explained, however, is why the U.S. has signed these agreements. Despite the fact that this question has not been empirically...

Research examining whether the laws of war change state behavior has produced conflicting results, and limitations of observational studies have stalled progress on the topic. To bring new evidence to the debate, I have conducted a survey experiment that directly tests whether one mechanism...

Policymakers and legal scholars routinely make “comparative institutional competence” claims — claims that one branch of government is better at performing a specified function than another, and that the more competent branch should be in charge of that function. Such claims pervade...

We present a new measure of judicial ideology based on judicial hiring behavior. Specifically, we utilize the ideology of the law clerks hired by federal judges to estimate the ideology of the judges themselves. These Clerk-Based Ideology (CBI) scores complement existing measures of judicial...

In the seventy-five years since the end of World War II, pairs of countries have entered into over a thousand bilateral labor agreements (BLAs) to regulate the cross-border flow of workers. These agreements have received little public or academic attention. This is likely, in part, because there...

The world’s biggest consumer markets—the European Union and the United States—have adopted different approaches to regulating competition. This has not only put the EU and US at odds in high-profile investigations of anticompetitive conduct, but also made them race to spread their...

Competition law has proliferated around the world. Due to data limitations, however, there is little systematic information about the substance and enforcement of these laws. In this paper, we address that problem by introducing two new datasets on competition law regimes around the world....

Competition laws have become a mainstay of regulation in market economies today. At the same time, past efforts to study the drivers or effects of these laws have been hampered by the lack of systematic measures of these laws across a wide range of years or countries. In this paper, we draw on...

Openness to international trade and adoption of antitrust laws can both curb anticompetitive behavior. But scholars have long debated the relationship between the two. Some argue that greater trade openness makes antitrust unnecessary, while others contend that antitrust laws are still needed to...

Beginning in the 1950s, a group of scholars primarily associated with the University of Chicago began to challenge many of the fundamental tenants of antitrust law. This movement, which became known as the Chicago School of Antitrust Analysis, profoundly altered the course of American antitrust...
