While confounding factors typically jeopardize the possibility to use observational data to measure peer effects, field experiments offer the possibility to obtain clean evidence. In this paper we measure the output of four randomly selected groups of individuals who were asked to fill letters...

Agency theory assumes that tighter monitoring by the principal should motivate the agent to raise his effort level whereas the ?crowding-out? literature suggests that it may reduce the overall work effort. These two assertions are not necessarily contradictory provided that the nature of the...

We study worker and firm behavior in an environment where worker effort could depend on co-workers? wages. Theoretically, we show that an increase in workers? ?concerns? with coworkers? wages should lead profit-maximizing firms to compress wages under quite general conditions. However, firms...

Many experiments indicate that most individuals are not purely motivated by material self interest, but also care about the well being of others. In this paper we examine tournaments among inequity averse agents, who dislike disadvantageous inequity (envy) and advantageous inequity (compassion)....

The theoretical probation literature shows that individuals have incentives to mimick "good workers" during periods of employment probation. This study empirically tests at the example of absence behavior, whether such behavioral responses to the incentives of probation periods exist. We find...

Employment protection systems are known to generate significant distortions in firms? hiring and firing decisions. We know much less about the impact of these regulations on worker effort. The goal of this paper is to fill in this gap and in particular to assess whether the provision of...

Some have observed that individuals perform worse after being promoted. The Peter Principle, which states that people are promoted to their level of incompetence, suggests that something is fundamentally misaligned in the promotion process. This view is unnecessary and inconsistent with the...

During the last two decades economists have made much progress in understanding incentives, contracts and organisations. Yet, they constrained their attention to a very narrow and empirically questionable view of human motivation. The purpose of this paper is to show that this narrow view of...

Temporary contracts provide employers with a tool to screen potential new employees and have been shown to provide "stepping stones" into permanent employment for workers. For both reasons workers on temporary contracts have an incentive to provide more effort than permanent employees. Using...

We analyze the impact of three different transfer fee systems on payoffs, contract lengths, training and effort incentives in European football. The different regimes, being used until 1995 (?Pre-Bosman? or P), currently in use (?Bosman? or B), and recently approved (?Monti? or M) differ with...
