The nature of the relationship between employers and employees has been changing over the last decades, with firms increasingly relying on contractors, temp agencies and franchises rather than hiring employees directly. We investigate the impact of this transformation on the wage structure by following jobs that are moved outside of the boundary of lead employers to contracting firms. For this end we develop a new method for identifying outsourcing of food, cleaning, security and logistics services in administrative data using the universe of social security records in Germany. We document a dramatic growth of domestic outsourcing in Germany since the early 1990s. Event-study analyses show that wages in outsourced jobs fall by approximately 10-15% relative to similar jobs that are not outsourced. We find evidence that the wage losses associated with outsourcing stem from a loss of firm-specific rents, suggesting that labor cost savings are an important reason why firms choose to contract out these services. Finally, we tie the increase in outsourcing activity to broader changes in the German wage structure, in particular showing that outsourcing of cleaning, security and logistics services alone accounts for around 10 percent of the increase in German wage inequality since the 1980s.

The Great Recession has renewed interest in Unemployment Insurance (UI) programs around the world. At the same time, there have been important advances in both theory and measurement of UI. In this paper, we first use the theory to present a unified treatment of the welfare effects of UI benefit levels and durations and derive convenient expressions of the disincentive effect of UI. We then discuss recent estimates of the effect of UI benefit levels and durations on labor supply based, to a large extent, on high-quality research designs and administrative data. We relate these estimates directly to the sufficient statistics identified by the model. We also discuss several active and open areas of research on UI. These include the effect of UI on aggregate labor market outcomes, the effect of UI on job outcomes, the long-term effects of UI, the effects of UI under non-standard behavioral assumptions, and the interactions of UI with other programs. While our review of the new experimental estimates confirms the range of negative labor supply effects of the previous literature, we show based on the model that these estimates are imperfect proxies for the actual disincentive effects. We also isolate several important areas in need for additional research, including estimates of the social value of UI as well as the effects of UI in less-developed countries.
