Do drivers reduce speeds when gasoline prices are high? Previous research investigating this energy conservation hypothesis produced mixed results. We take a fresh look at the data and estimate a significant negative relationship between speeding and gasoline prices. This presents a new...

Do negative incentives or sticks in education improve student outcomes? Since the late 1980s, several U.S. states have introduced No Pass No Drive (NPND) laws that set minimum academic requirements for teenagers to obtain driving licenses. Using data from the American Community Survey (ACS) and...

Over a million people in the United States are employed in private security and law enforcement, yet very little is known about the effects of private police on crime. The current study examines the relationship between a privately-funded university police force and crime in a large U.S. city....

We estimate a structural model of borrowing and lending in the illegal money lending market using a unique panel survey of 1,090 borrowers taking out 11,032 loans from loan sharks. We use the model to evaluate the welfare effects of alternative law enforcement strategies. We find that a large...

We study how the political cost of enforcing a lockdown in response to the COVID- 19 outbreak relates to citizens' propensity for altruistic punishment in Italy, the early epicenter of the pandemic. Approval for the government's management of the crisis decreases with the amount of the penalties...

We conduct a field experiment to examine whether the deterrent effect of law enforcement depends on the salience of law enforcement activity. Our focus is on illegal disposal of household garbage in residential areas. At a random subset of 56 locations in a mid-sized city, law enforcement...

We study the impact on road safety of one-day massive speed limit monitoring operations (SLMO) accompanied by media campaigns that announce the SLMO and provide information on the dangers of speeding. Using register data on the universe of police reported accidents in a generalized...

We analyze the effect of imposed benefit sanctions on the unemployment-to-employment transition of unemployed people entitled to unemployment compensation on the basis of register data from the German Federal Employment Agency. We combine propensity score matching with a discrete-time hazard...

The focus of this paper is the analysis of the persistent lawlessness attitude observed in some transition and developing countries where an overall increase in the quality of institutions is recorded. The mechanism of information diffusion on institutional quality is explored using a model...

This paper discusses the literature on the enforcement of incomplete contracts. It compares legal enforcement to enforcement via relationships and reputations. A number of mechanisms, such as the repeat purchase mechanism (Klein and Leffler (1981)) and efficiency wages (Shapiro and Stiglitz...
