Many jurisdictions levy sizable fines and fees (legal financial obligations, or LFOs) on criminal defendants. Proponents argue LFOs are a "tax on crime" that funds courts and provides deterrence; opponents argue they do neither. We examine the fiscal implications of lowering LFOs. Incentives to...

Algorithms (in some form) are already widely used in the criminal justice system. We draw lessons from this experience for what is to come for the rest of society as machine learning diffuses. We find economists and other social scientists have a key role to play in shaping the impact of...

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,...

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...

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...

This paper uses data from 700+ felony trials in Sarasota and Lake Counties in Florida from 2000-2010 to examine the role of age in jury selection and trial outcomes. The results imply that prosecutors are more likely to use their peremptory challenges to exclude younger members of the jury pool,...

The myriad uncertainties common to the process of adjudication--concerning evidence that opposing parties will present, legal issues that will become relevant, illness of witnesses, and the like--lead to two social problems. First, when unanticipated events occur, the information that parties...

Post-communist countries offer new evidence on the relative importance of courts and relationships in enforcing contracts. Belief in the effectiveness of courts has a significant positive effect on the level of trust shown in new relationships between firms and their customers. Well-functioning...

We examine the effect of hearing cases alongside female judicial colleagues on the probability that a federal judge hires a female law clerk. Federal judges are assigned to cases and to judicial panels at random and have few limitations on their choices of law clerks: these two features make the...

Extremely narrow election outcomes--such as could be reversed by rejecting a few thousand ballots--are likely to trigger dispute over the results. Narrow vote tallies may generate recounts and litigation; they may be resolved by courts or elections administrators (e.g., Secretaries of State...
