Holmström's (1982/99) career concerns model has become a workhorse for analyzing agency issues in many fields. The underlying signal jamming argument requires players to use information in a Bayesian way, which is difficult to directly test with field data: typically little is known about the information that individuals base their decisions on. Our laboratory experiment provides prima facie evidence: i) the signal jamming mechanism successfully creates incentives on the labor supply side; ii) decision errors take time to decrease; iii) while subjects' average beliefs are remarkably consistent with play, a mild winner's curse arises on the labor demand side.JEL-Classification: C91, D83, L14

In most Organization for Economic Cooperation and Development (OECD) countries, unemployment benefits are tied to previous labor earnings. The authors study the progressivity of this indexation with regard to its effects on employment, output, and wages in three non-Walrasian equilibrium models of the labor market. In the cases of decentralized union wage bargaining and search unemployment and Nash wage bargaining, employment, output, and wages increase with the degree of indexation. The indexation of unemployment benefits to previous earnings, however, has no effect in the case of efficiency wages. The results also suggest that a more progressive indexation of unemployment benefits is welfare enhancing if wages are bargained.

Koch Albrecht Morgenstern The Institute for the Study of Labor (IZA) in Bonn is a local and virtual international research center and a place of communication between science, politics and business. IZA is an independent nonprofit organization supported by Deutsche Post Foundation. The center is associated with the University of Bonn and offers a stimulating research environment through its international network, workshops and conferences, data service, project support, research visits and doctoral program. IZA engages in (i) original and internationally competitive research in all fields of labor economics, (ii) development of policy concepts, and (iii) dissemination of research results and concepts to the interested public.

To innovate, employees need to develop novel ideas and coordinate with each other to turn these ideas into better products and services. Work outcomes provide signals about employees' abilities to the labor market, and therefore career concerns arise. These can both be 'good' (enhancing incentives for effort in developing ideas) and 'bad' (preventing voluntary coordination). Our model shows how the firm designs its explicit incentive system and organizes work processes to take these conflicting forces into account. The comparative statics results suggest a link between the increased use of teams and recent changes in labor market returns to skills.JEL Classification: D86, J30, L14, L20, M12, O30
