The recovery from the Covid-19 crisis will force governments to accelerate transformation in their menu of labor market policy tools. The crisis was a stress test for unemployment insurance schemes as it involved a sudden and unexpected shutdown of a very large set of activities. This forced countries to introduce, often from scratch, income support schemes for workers under new forms of employment, and the self-employed. There was also a considerable expansion of short-time work schemes notably towards the small business. The challenge ahead of us is perhaps even harder as post-Covid19 labor markets are likely to be characterized by substantial labor reallocation. Major innovations in labor market policy are required to smooth consumption of workers involved in this reallocation. We survey the large body of research on schemes reducing the costs of reallocation complementary to unemployment insurance. Our attention is on short-time work (preventing layoffs by subsidizing hours reductions), partial unemployment insurance (enabling workers to combine unemployment benefits with low-income jobs), and wage insurance (offering a temporary wage subsidy to workers changing jobs). The properties of these new schemes are first presented and compared to those of standard unemployment benefits. Next the main results of the empirical literature on the effects of wage insurance, partial unemployment insurance and short-time work are presented. A final section is devoted to discussing directions for further research.

This paper examines a labor law reform implemented in Portugal in 2009 which restricted the use of fixed-term contracts to reduce labor market segmentation. The reform targeted establishments created by large firms above a specific size threshold, covering about 15% of total employment. Drawing on linked employer-employee longitudinal data and regression discontinuity methods, we find that, while the reform was successful in reducing the number of fixed-term jobs, it did not increase the number of permanent contracts and decreased employment in large firms. However, we find evidence of positive spillovers to small firms that may bias reduced form estimates. To evaluate general equilibrium effects, we build and estimate a directed search and matching model with endogenous number of establishments and jobs. We find spillover effects that induce small biases on reduced form estimates but that significantly change the evaluation of the overall impact of the reform because they diffuse to the whole economy. We estimate that the reform slightly reduced aggregate employment and had negative effects on the welfare of employees and unemployed workers.
