We collect rich establishment-level data about advance layoff notices filed under the Worker Adjustment and Retraining Notification (WARN) Act since January 1990. We present in-sample evidence that the number of workers affected by WARN notices leads state-level initial unemployment insurance...

In many countries, the termination of employment contracts has to be either on employer initiative or on employee initiative. In 2008, the French government introduced a change in doctrine: it became possible to terminate employment contracts by mutual consent at a lower cost. We show that the...

In many countries, the termination of employment contracts has to be either on employer initiative or on employee initiative. Furthermore, the cost of the procedure is borne mainly by the contracting party who takes the initiative and there is little room for sharing costs. The implicit doctrine...

A simple model evaluating a firm’s optimal employment reaction to an imminent recession is presented. Firing costs shelter employment – and this effect is typically amplified by uncertainty due to an option value of waiting. However, this job protection effect is reduced if the expected...

Sunk firing costs shelter employment and this effect is typically amplified by uncertainty due to an option value of waiting. Thus, if sunk firing costs are high, e.g. due to a employment protection legislation, and if recession related losses are with a high probability expected to be only...

This paper explores how the introduction of an experience rated system of unemployment insurance affects employment and welfare in a model where implicit contracts between firms and workers give rise to wage rigidities and unemployment. In the literature, it has been argued that experience rated...

We examine self-enforcing contracts between risk-averse workers and risk-neutral firms (the ‘invisible handshake') in a labor market with search frictions. Employers promise as much wage smoothing as they can, consistent with incentive conditions that ensure they will not renege during...

This paper explores, both theoretically and empirically, how firing costs affect worker productivity and turnover. We develop a model in which workers are essential to knowledge transfer between firms and worker effort is firm-specific in the sense that a worker can be fired before reaping the...
