This paper is concerned with the business cycle dynamics in search-and-matching models of the labor market when agents are ex post heterogeneous. We focus on wealth heterogeneity that comes as a result of imperfect opportunities to insure against idiosyncratic risk. We show that this...

The paper extends the basic Stiglitz (1982) model of optimal nonlinear income taxation into a model featuring endogenous unemployment and wages. This means that the government needs to consider the effects on wages and unemployment when designing the optimal tax function. The tax systems'...

The paper develops a two-sector general equilibrium search model where goods are produced exclusively in the market and services are produced both in the market and within the households. We use the model to examine how unemployment and welfare are affected by labor taxes in general and sectoral...

The paper extends the basic Stiglitz (1982) model of optimal income taxation into general search equilibrium. When we extend the basic taxation model to include a more realistic treatment of the labor market, a number of new interesting mechanisms arise. When wages are fixed we find that a work...

This paper explores the rationale for unemployment benefits as a complement to optimal non-linear income taxation. High-skilled workers and low-skilled workers face different exogenous risks of being unemployed. As long as the low-skilled workers face a higher unemployment risk, we find that...

Using a unique data set and a novel identification strategy, we estimate the effect of minimum wage increases on job vacancy postings. Utilizing occupation-specific countylevel vacancy data from the Conference Board's Help Wanted Online for 2005-2018, we find that state-level minimum wage...

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...

Existing unemployment insurance systems in many OECD countries involve a ceiling on insurable earnings. The result is lower replacement rate for employees with relatively high earnings. This paper examines whether replacement rates should decrease as the level of earnings rises. The framework is...

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...

This paper analyzes the design of optimal unemployment insurance in a search equilibrium framework where search effort among the unemployed is not perfectly observable. We examine to what extent the optimal policy involves monitoring of search effort and benefit sanctions if observed search is...
