A central requirement in the design of a legal system is the protection of law enforcers from coercion by litigants through either violence or bribes. The higher the risk of coercion, the greater the need for protection and control of law enforcers by the state. This perspective explains why, in...

We investigate the evolution of common law under overruling, a system of precedent change in which appellate courts replace existing legal rules with new ones. We use a legal realist model, in which judges change the law to reflect their own preferences or attitudes, but changing the law is...

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....

Djankov et al. (2003a) propose and measure for 109 countries in the year 2000 an index of formalism of legal procedure for two simple disputes: eviction of a non-paying tenant and collection of a bounced check. For a sub-sample of 40 countries, we compute this index every year starting in 1950,...

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...

We document evidence of corruption in Chinese state asset sales. These sales involved stakes in partially privatized firms, providing a benchmark - the price of publicly traded shares - to measure underpricing. Underpricing is correlated with deal attributes associated with misgovernance and...

We study the wealth accumulation of Indian parliamentarians using public disclosures required of all candidates since 2003. Annual asset growth of winners is on average 3 to 6 percentage points higher than runners-up. By performing a within-constituency comparison where both runner-up and winner...

We examine the labor supply of politicians using data on Members of the European Parliament (MEPs). We exploit the introduction of a law that equalized MEPs' salaries, which had previously differed by as much as a factor of ten. Doubling an MEP's salary increases the probability of running for...

Generally speaking, better educated countries have better governments, an empirical regularity that holds in both dictatorships and democracies. We suggest that a possible reason for this fact is that educated people are more likely to complain about misconduct by government officials, so that,...
