In the nineties, average firm size decreased, organisations decentralized, and workers preferences shifted from large to small firms. Our model identifies the economic forces behind this trend. Small firms with little capital at risk are subject to risk-shifting. They realize more of their...

We test the effectiveness of team incentives by running a natural field experiment in a retail chain of 193 shops and 1,300 employees. As a response to intensified product market competition, the firm offered a bonus to shop teams for surpassing sales targets. A bonus to teams rather than...

We investigate a team setting in which workers have different degrees of commitment to the outcome of their work. We show that if there are complementarities in production and if the team manager has some information about team members, interventions that the manager undertakes in order to...

We conduct experimental games with police applicants in Germany to investigate whether intrinsically motivated agents self-select into public service. Our focus is on trustworthiness and the willingness to enforce norms as key dimensions of intrinsic motivation in the police context. We find...

We test two hypotheses, based on sexual selection theory, about gender differences in costly social interactions. Differential selectivity states that women invest less than men in interactions with new individuals. Differential opportunism states that women's investment in social interactions...

Irregular migrants from Africa and the Middle East flow into Europe along land and sea routes under the control of human smugglers. The demise of the Gaddafi regime in 2011 marked the opening of the Central Mediterranean Route for irregular border - crossing between Libya and Italy. This...

We introduce financial constraints in a theoretical analysis of illegal immigration. Intermediaries finance the migration costs of wealth-constrained migrants, who enter temporary servitude contracts to pay back the debt. These debt/labor contracts are more easily enforceable in the illegal than...

Many countries are trying to incentivize fathers to increase their share in parental leave and in household work to improve female labor market opportunities. Our unique data set stems from a natural experiment in Sweden. The data comprises all children born before (control group) and after the...

We develop a theory of firm scope in which integrating two firms into one facilitates the allocation of resources, but leads to weaker incentives for effort, compared with non-integration. Our theory makes minimal assumptions about the underlying agency problem. Moreover, the benefits and costs...
