This paper explores the sources of bargaining power in wage negotiations. In the standard analyses of wage bargaining, the negotiation partners are specified a priori, and thus it is impossible to address the question of how they achieve and retain their negotiating positions, on which their...

We provide new empirical evidence regarding the magnitude and the determinants of a firm's costs required to fill a vacancy. The average costs required to fill a vacancy for a skilled worker in Switzerland amount to about 16 weeks of wage payments. The main components of the vacancy costs are...

Large international differences in the price of labor can be sustained by differences between workers, or by natural and policy barriers to worker mobility. We use migrant selection theory and evidence to place lower bounds on the ad valorem equivalent of labor mobility barriers to the United...

In a randomized control trial, the precision of an average treatment effect estimator can be improved either by collecting data on additional individuals, or by collecting additional covariates that predict the outcome variable. We propose the use of pre-experimental data such as a census, or a...

To estimate the causal effect of employment protection on firms' worker selection, we study a policy change that reduced dismissal costs for the employers of over a tenth of Sweden's workforce. Our difference-in-differences analysis of firms' hiring uses individual ability measures including...

Previous studies report a range of estimates for the response of female labor supply and childcare attendance to childcare prices. We shed new light on these questions using a policy reform that raises the price of public daycare. After the reform, children are 8 percentage points less likely to...

Recent work criticises both the logic and relevance of the theoretical basis of the approach to estimating the costs of raising children adopted in much of the economics literature. This tends to be restricted purely to models in which the household members consume market goods with given...
