In a 2007 article, Adam Cox and Eric Posner developed a “Second Order” theory of immigration law that offered predictions about when countries are likely to provide non-citizens with strong legal protections from removal. They argued that states benefit when migrants make...

Law professors routinely accuse each other of making politically biased arguments in their scholarship. They have also helped produce a large empirical literature on judicial behavior that has found that judicial opinions sometimes reflect the ideological biases of the judges who join them. Yet...

There is considerable variation in countries’ respect for human rights. Scholars have tried to explain this variation on the basis of current conditions in countries—such as democracy and civil war—and events from the recent past, such as ratification of human rights treaties. This...

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...

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...

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....

The Untied States has signed 47 Bilateral Investment Treaties (BITs) over the last three decades. The standard explanation for why the United States’ government signed those BITs is that it was motivated by a desire to promote the development of international investment law and to protect...

A fundamental academic assumption about the federal courts of appeals is that the three judge panels that hear cases have been randomly configured. Scores of scholarly articles have noted this “fact,” and it has been relied on heavily by empirical researchers. Even though there are practical...
