Labor market rigidities and misallocation: Evidence from a natural experiment
利用比利时政策变化，发现增加蓝领工人就业保护会扩大其边际产品与边际成本之间的差距，导致劳动力错配加剧。
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.
