This paper uses a large-scale two-level randomized experiment to study direct and displacement effects of job search assistance. Our findings show that the assistance reduces unemployment among the treated, but also creates substantial displacement leading to higher unemployment for the...

This paper re-examines inference for cluster samples. Sensitivity analysis is proposed as a new method to perform inference when the number of groups is small. Based on estimations using disaggregated data, the sensitivity of the standard errors with respect to the variance of the cluster...

This paper proposes a new framework for analyzing the effects of sequences of treatments with duration outcomes. Applications include sequences of active labor market policies assigned at specific unemployment durations and sequences of medical treatments. We consider evaluation under...

Learning-by-doing is a fundamental concept in economics but a challenging one to document in high-skilled settings due to non-random assignment of workers to tasks and lacking performance measures. Our paper overcomes these challenges in the context of heart attack treatments in Sweden, where we...

Employment and wage subsidies are used to combat long-term unemployment, yet there is little research to guide the design of such programs. Discontinuities in the design and implementation of wage subsidies under the Swedish New Start Jobs-policy allow us to study effects of both subsidy rate...
