We compare "real business cycle" and increasing returns models of economic fluctuations. In these models, business cycles are driven by productivity changes resulting either from technology shocks or from crucial building blocks that give both types of models hope of fitting the data. These...

Does it matter for the outcome of a trial who the judge is? Legal practitioners typically believe that the answer is yes, yet legal scholarship sees trial judges as predictably enforcing established law. Following Frank (1951), we suggest here that trial judges exercise considerable discretion...

Entrepreneurs who start new firms may choose not-for-profit status as a means of committing to soft incentives. Such incentives protect donors, volunteers, consumers and employees from ex post expropriation of profits by the entrepreneur. We derive conditions under which completely...

In the last decade, economists have produced a considerable body of research suggesting that the historical origin of a country's laws is highly correlated with a broad range of its legal rules and regulations, as well as with economic outcomes. We summarize this evidence and attempt a unified...

This paper explores Paul N. Rosenstein-Rodan's idea that simultaneous industrialization of many sectors of the economy can be profitable for them all even when no sector can break even industrializing alone. The authors analyze this idea in the context of an imperfectly-competitive economy with...

During the Progressive Era at the beginning of the 20th century, the United States replaced litigation by regulation as the principal mechanism of social control of business. To explain why this happened, we present a model of choice of law enforcement strategy between litigation and regulation...

In developing countries, informal firms (those that are not registered with the government) account for about half of all economic activity. We consider three broad views of the role of such firms in economic development. According to the romantic view, these firms would become the engine of...

In many countries, the operation of legal, political and regulatory institutions is subverted by the wealthy and the politically powerful for their own benefit. This subversion takes the form of corruption, intimidation, and other forms of influence. We present a model of such institutional...

We examine the practice of military conscription around the world from the perspective of two standard theories, and a new one, which emphasizes the fixed cost of introducing and administering the draft as a deterrent to its use. We find that, holding the relative size of the military constant,...
