In the standard moral hazard model, withholding of effort by the agent is not observable to the principal. We argue that this assumption has to be changed in applications that study corruption. The overwhelming majority of cases where corrupt politicians have been punished involve the detection...

We develop a moral hazard model with auditing where both the principal and the agent can influence the probability that the true state of nature is verified. This setting is widely applicable for situations where fraudulent reporting with costly state verification takes place. However, we use...

This paper investigates multi-item moral hazard with auditing contests. Although the presented model is widely applicable, we choose tax evasion as an exemplary application. We introduce a tax-evasion model where tax authority and taxpayer invest in detection and concealment. The taxpayers have...

A profit-maximizing auctioneer can provide a public good to a group of agents. Each group member has a private value for the good being provided to the group. We investigate an auction mechanism where the auctioneer provides the good to the group, only if the sum of their bids exceeds a reserve...

Our survey of private manufacturing firms finds the size of hidden ‘unofficial’ activity to be much larger in Russia and Ukraine than in Poland, Slovakia and Romania. A comparison of cross-country averages shows that managers in Russia and Ukraine face higher effective tax rates, worse...

The rate at which police officers were murdered rose over the 1960s, although expected penalties also grew more severe. During that period, a subjective index indicates, arrest suspects may have become more prone to commit crimes for impulsive or political reasons rather than out of rational...

This paper, a synthesis of salient findings of the authors’ book entitled “Investment Climate Around the World: Voices of the Firms from the World Business Environment Survey”, and based on a chapter in “Pathways Out of Poverty: Private Firms and Economic Mobility in Developing...

The present paper uses a survey of 1062 Czechs and 524 Slovaks to ask why people evade taxes. We maintain that the Czech and Slovak Republics are “twins” separated at birth and that divergences between these countries since their separation in 1992 can explain divergences in their rates of...

We use a dataset of 1062 individuals from the Czech Republic to forecast the evolution of tax evasion in that country. We ask each respondent how intensely (never, sometimes, often) he evaded taxes in 1995, 1999, and 2000, to calculate probabilities the average individual will move between these...
