In Germany, the system of unemployment insurance has been in surplus since 2011, as the author Alfred Boss reveals in his analysis. Only a small part of the surplus is due to the cyclical stance of the German economy. The surplus mainly is a structural one. The rate of contribution to unemployment insurance should be reduced from 3 to 2.5 percent beginning in 2018. This would reverse the increase of the overall rate of contributions to social security in 2017. The increase of employment would be fostered.
