Abadie and Imbens (2008, Econometrica) showed that classical bootstrap schemes fail to provide correct inference for K-nearest neighbour (KNN) matching estimators of average causal effects. This is an interesting result showing that bootstrap should not be applied without theoretical...

During the last decade several empirical studies have stressed the importance of norms and social interactions for explaining sickness absence behavior. In this context public discussions about the intentions of the insurance, and of the rights and duties of the receivers, may be important for...

This study investigates possible reasons for the gender difference in sickness absence. We estimate both short- and long-term effects of parenthood in a within-couple analysis based on the timing of parenthood. We find that after entering parenthood, women increase their sickness absence by...

This study evaluates the long-term cost of unemployment in Finland by focusing on the deep recession period of the early 1990s. The number of plant closures increased sharply during the recession and the unemployment rate rose by more than 13 percentage points. In the analysis, prime working-age...

Compared to earlier studies on this topic, we have more and better data. From our GMM estimations, we find that (i) there are...
