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...

We examine peer effects in welfare use among immigrants to Sweden by exploiting a governmental refugee placement policy. We distinguish between the quantity of contacts the number of individuals of the same ethnicity and the quality of contacts welfare use among members of the ethnic group. OLS...

In Sweden, children typically start compulsory school the year they turn seven. Hence, individuals born just before or just after the new year, have about the same date of birth but start school at different ages. We exploit this source of exogenous variation, to identify the effects of age at...

This paper discusses the evaluation problem using observational data when the timing of treatment is an outcome of a stochastic process. We show that, without additional assumptions, it is not possible to estimate the average treatment effect and treatment on the treated. It is, however,...

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...

This paper analyses the effects of maternal school starting age and maternal age-at-birth on children's short and long-term outcomes using Finnish register data. We exploit a school-starting-age rule for identification. Mothers who are born after the school entry cut-off give birth at higher...

We examine the changes in the relative rewards to cognitive and non-cognitive skill during the time period 1992–2013. Using unique administrative data for Sweden, we document a secular increase in the returns to non-cognitive skill, which is particularly pronounced in the private sector and at...
