Tacit collusion reduces welfare comparably to explicit collusion but remains mostly unaddressed by antitrust enforcement which greatly depends on evidence of explicit communication. We propose to target specific elements of firms’ behavior that facilitate tacit collusion by providing...

In this paper the employment of Scottish and English self- reporting drug users is considered using data drawn from the Scottish and British Crime Surveys. Univariate and bivariate estimates of the probability of being employed reveal a robustly negative and statistically significant association...

This paper presents estimates of a dynamic individual-level model of cannabis consumption, using data from a 1998 survey of young people in Britain. The econometric model is a split-population generalisation of the non-stationary Poisson process, allowing for a separate dynamic process for...

This paper presents an econometric model that combines macroeconomic time series data with historical series relating to political instability in Israel during the Intifada period, in order to provide a conservative estimate of the extent to which variations in economic performance over time...

We study experimentally whether anti-corruption policies with a focus on bribery might be insufficient to uncover more subtle ways of gaining an unfair advantage. In particular, we investigate whether an implicit agreement to exchange favors between a decision-maker and a lobbying party serves...

In a seminal paper, Becker (1968) showed that the most efficient way to deter crime is to impose the severest possible penalty (to maintain adequate deterrence) with the lowest possible probability (to economize on costs of enforcement). We shall call this the Becker proposition (BP). The BP is...

All models in Law and Economics use punishment functions (PF) that incorporates a trade-off between probability of detection, p, and punishment, F. Suppose society wishes to minimize the total costs of enforcement and damages from crime, T (p; F). For a given p, an optimal punishment function...

Weak institutions are shown to create scope for public banks to play a growth-promoting role, even if such banks are less efficient than private banks.

After the collapse of the Soviet Union, more than 3 million people with German ancestors immigrated to Germany under a special law granting immediate citizenship. Exploiting the exogenous allocation of ethnic German immigrants by German authorities across regions upon arrival, we find that...

We discuss survey evidence on individuals' willingness to sanction norm violations - such as evading taxes, drunk driving, fare dodging, or skiving o work - by expressing disapproval or social exclusion. Our data suggest that people condition their sanctioning behavior on their belief about the...
