Explanations of unethical behavior often neglect the role of competition, as opposed to greed, in assuring its spread. Using the examples of child labor, corruption, excessive' executive pay, corporate earnings manipulation, and commercial activities by universities, this paper clarifies the...

Economic theory and evidence from a variety of debt markets shed light on current reform proposals concerning emerging market debt. Debt markets, including the U.S. municipal bond market, generally function best when the rights of creditors are protected most effectively. Since current IMF...

Regulation of economic activity is ubiquitous around the world, yet standard theories predict it should be rather uncommon. I argue that the ubiquity of regulation is explained not so much by the failure of markets, or by asymmetric information, as by the failure of courts to solve contract and...

Private ownership should generally be preferred to public ownership when the incentives to innovate and to contain costs must be strong. In essence, this is the case for capitalism over socialism, explaining the dynamic vitality' of free enterprise. The great economists of the 1930s and 1940s...

We evaluate Richard Posner's famous hypothesis that common law converges to efficient legal rules using a model of precedent setting by appellate judges. Following legal realists, we assume that judicial decisions are subject to personal biases, and that changing precedent is costly to judges....

We investigate cross-country determinants of private credit, using new data on legal creditor rights and private and public credit registries in 129 countries. We find that both creditor protection through the legal system and information sharing institutions are associated with higher ratios of...

We revisit the debate over whether political institutions cause economic growth, or whether, alternatively, growth and human capital accumulation lead to institutional improvement. We find that most indicators of institutional quality used to establish the proposition that institutions cause...

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,...

We present a model of the creation of social networks, such as political parties, trade unions, religious coalitions, or political action committees, through discussion and mutual persuasion among their members. The key idea is that people are influenced by those inside their network, but not by...

We present a model of efficient regulation along the lines of Demsetz (1967). In this model, setting up and running regulatory institutions takes a fixed cost, and therefore jurisdictions with larger populations affected by a given regulation are more likely to have them. Consistent with the...
