We study whether information frictions and corruption perceptions deter firms from doing business with the government. We conduct two nationwide randomized controlled trials (RCTs) in collaboration with the national public procurement supervisory and anti-corruption agency in Uganda. The first...

This paper provides causal evidence of the effect of private prisons on criminal sentencing. Our identification strategy uses state-level changes in private-prison capacity and compares changes in sentencing across trial court pairs that straddle state borders. We find that a doubling of private...

This paper examines the use of fines and imprisonment to deter individuals from engaging in harmful activities. These sanctions are analyzed separately as well as together, first for identical risk-neutral individuals and then for two groups of risk-neutral individuals who differ by wealth. When...

Potential offenders discount the future disutility of sanctions and the state discounts the future costs of sanctions. Prison has higher disutility and...

The deterrence of crime and its reduction through incapacitation are studied in a simple multiperiod model of crime and law enforcement. Optimal imprisonment sanctions and the optimal probability of sanctions are determined. A point of emphasis is that the incapacitation of individuals is often...
