Unemployment Insurance in Theory and Practice

A hallmark of modern labor economics is the close interplay between the development of theory, data sources and econometric testing. The evolution of the economic analysis of unemployment insurance provides a good illustration. New theoretical approaches, in particular job-search theory, have inspired a large amount of empirical research, some of it methodologically innovative and most of it highly relevant for economic policy. The paper presents a broad survey and an assessment of the economic analysis of unemployment insurance as it has evolved since the 1970s.

Labor Taxation in Search Equilibrium with Home Production

Conventional models of equilibrium unemployment typically imply that proportional taxes on labor earnings are neutral with respect to unemployment as long as the tax does not affect the replacement rate provided by unemployment insurance, i.e., unemployment benefits relative to after-tax earnings. When home production is an option, the conventional results may no longer hold. This paper uses a search equilibrium model with home production to examine the employment and welfare implications of labor taxes. The employment effect of a rise in a proportional tax is found to be negative for sufficiently low replacement rates, whereas it is ambiguous for moderate and high replacement rates. Numerical calibrations of the model indicate that employment generally falls when proportional labor taxes are raised. Progressive labor taxes increase labor market tightness but have ambiguous effects on search effort and employment.Home production, job search, unemployment, taxation

Labor Taxation in Search Equilibrium with Home Production.

Conventional models of equilibrium unemployment typically imply that pro-portional taxes on labor earnings are neutral with respect to unemployment as long as the tax does not affect the replacement rate provided by unem-ployment insurance, i.e., unemployment benefits relative to after-tax earn-ings. When home production is an option, the conventional results may no longer hold. This paper uses a search equilibrium model with home pro-duction to examine the employment and welfare implications of labor taxes. The employment effect of a rise in a proportional tax is found to be negative for su¢ciently low replacement rates, whereas it is ambiguous for moderate and high replacement rates. Numerical calibrations of the model indicate that employment generally falls when proportional labor taxes are raised. Progressive labor taxes increase labor market tightness but have ambiguous e¤ects on search e¤ort and employment. The numerical calibrations indicate positive employment effects.

Optimal unemployment insurance design: time limits, monitoring, or workfare?

This paper analyses crucial design features of unemployment insurance (UI) policies. We examine three different means of improving the efficiency of UI: the duration of benefit payments, monitoring in conjunction with sanctions, and workfare. To that end we develop a quantitative model of equilibrium unemployment. The model features worker heterogeneity in preferences for leisure. The numerical analysis suggests that a system with monitoring and sanctions restores search incentives most effectively, since it brings additional incentives to search actively so as to avoid the sanction. Therefore, the UI provider can offer a more generous UI replacement rate in a system with monitoring and sanctions than in the other two systems. Workfare appears to be inferior to the other two systems.Unemployment insurance; search equilibrium; time limits; monitoring and sanctions; workfare

We examine three different means of improving the efficiency of UI: the duration of benefit payments, monitoring in conjunction with sanctions, and workfare. To that end we develop a quantitative model of equilibrium unemployment. The model features worker heterogeneity, which takes the form of differences in preferences for leisure. All the instruments are ways of limiting the duration of UI benefit receipt and the model can be used to compare them in a coherent fashion. The analysis suggests that a system with monitoring and sanctions restores search incentives most effectively, since it brings additional incentives to search actively so as to avoid the sanction. Therefore, the UI provider can offer a more generous UI replacement rate in a system with monitoring and sanctions than in the other two systems.

Improving incentives in unemployment insurance: A review of recent research

This paper provides a review of the recent literature on how incentives in unemployment insurance (UI) can be improved. We are particularly concerned with three instruments, viz. the duration of benefit payments (or more generally the time sequencing of benefits), monitoring in conjunction with sanctions, and workfare. Our reading of the theoretical literature is that the case for imposing a penalty on less active job search is fairly solid. A growing number of empirical studies, including randomized experiments, are in line with this conclusion.Unemployment insurance; search; monitoring; sanctions; workfare

Part-Time Unemployment and Optimal Unemployment Insurance

A significant fraction of the labor force consists of employed workers who are part-time unemployed (underemployed) in the sense that they are unable to work as much as they prefer. This paper develops a search and matching model to study the design of optimal unemployment insurance in an economy with unemployment as well as part-time unemployment. Part-time unemployment provides income insurance and serves as a stepping stone to full-time jobs. Unemployment benefits for part-timers increase the outflow from unemployment to part-time work but reduce the outflow from part-time work to full-time employment. We examine the optimal structure of benefits for unemployed and underemployed workers. The results indicate non-negligible welfare gains associated with time limits for unemployment benefits as well as for part-time benefits. The welfare gains from optimal UI are larger when wages are fixed than when they are flexible.job search, part-time unemployment, unemployment insurance

Temporary Work in Turbulent Times: The Swedish Experience

Sweden has experienced a substantial increase in temporary work over the 1990s, with most of the rise occurring during a severe macroeconomic recession with mass unemployment. By the early 1990s, workers on fixed-term contracts accounted for 10 percent of the number of employees; by the end of the decade they accounted for 16 percent. The paper presents the Swedish institutional setting, documents basic stylised facts about fixed-term contracts, and discusses the causes of their increased prevalence. Our analysis reveals that open-ended and temporary employment exhibit strikingly different cyclical behaviour with temporary employment being more volatile. A recession is associated with an initial decline in temporary employment followed by a sharp rise from the trough to the end of the recession. We argue that the severe recession of the 1990s is a major factor behind the rise in temporary work in Sweden. Adverse macroeconomic conditions make firms more prone to offer fixed-term contracts and workers more willing to accept them.Temporary jobs; Labour market dynamics; Unemployment
