Abstract: | Abstract. 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 systems of unemployment insurance may reduce long-term employment as firms anticipate the higher costs of layoffs implied by experience rating. Our analysis shows that the introduction of experience rating may increase or decrease long-term employment but it unambiguously raises welfare. |
