Within a laboratory experiment we investigate a principal-agent game in which agents may,first, self-select into a group task (GT) or an individual task (IT) and, second, choose workeffort. In their choices of task and effort the agents have to consider pay contracts for bothtasks as offered by...

The standard approach to nominal illusion in Economics sees it as a transitory phenomenon, as economic agents eventually see through the nominal veil, making the right choices. Recent empirical studies suggest that money illusion may persist, distorting real prices in a variety of economic...

Sick-pay is a common provision in labor contracts. It insures workersagainst a sudden loss of income due to unexpected absences andhelps them smooth consumption. Therefore, many governments findsick-pay socially desirable and choose to mandate its provision. Butsick-pay is not without its...

Individuals exhibit a randomization preference if they prefer random mix-tures of two bets to each of the involved bets. Such preferences provide thefoundation of various models of uncertainty aversion. However, it has to ourknowledge not been empirically investigated whether uncertainty-averse...

We discuss how the use of field experiments sheds light on long standing research questionsrelating to firm behavior. We present insights from two classes of experiments: within andacross firms, and draw common lessons from both sets. Field experiments within firmsgenerally aim to shed light on...

The paper studies the role of information transparency on fairness concerns, welfare and efficiency. When the firm's productivity and ultimately profits are revealed, wage offers induce relatively fair divisions of potential gains and workers respond with higher performance. Workers respond not...

We study experimentally partnership protocols of the sort proposed by Kalai and Kalai (2010), for bilateral trade games with incomplete information. We utilize the familiar game analyzed by Chatterjee and Samuelson (1983) and Myerson and Sattherwaite (1983), with a buyer and seller with value...

Most economic models are based on the self-interest hypothesis that assumes that all people are exclusively motivated by their material self-interest. In recent years experimental economists have gathered overwhelming evidence that systematically refutes the self-interest hypothesis and suggests...

This paper reports on a two-task principal-agent experiment in which only one task is contractible. The principal can either offer a piece-rate contract or a (voluntary) bonus to the agent. Bonus contracts strongly outperform piece rate contracts. Many principals reward high efforts on both...
