Labor market rigidities and misallocation: Evidence from a natural experiment

This paper estimates the impact of labor market rigidities on labor misallocation. To this end, we use a recent policy change in Belgium, leading to an increase in employment protection for blue-collar workers and a decrease in employment protection for white-collar workers. The wedge between marginal product and marginal cost - the gap - is used as a measure for misallocation. Using a rich data set of the universe of Belgian firms, evidence shows that a firm with 90% blue-collar workers experienced after the policy change an increase in the gap of 3300 euro relative to a firm with 10% of blue-collar workers.
