Reevaluating the German labor market miracle

Abstract

Abstract From 2003 to 2018, employment in Germany increased by 7.3 million, or by 19.3 % – growth not observed since unification. This “labor market miracle” was marked by a persistent and significant expansion of both part-time and low-wage jobs and a deterioration in pay for these jobs, while total hours hardly increased; overall wage growth returned only after 2011. These developments followed in the wake of the landmark Hartz reforms (2003–2005). A modified framework of Katz and Murphy (1992) predicts negative correlation of wages with both relative employment and participation across cells in the period following these reforms. In contrast, wage moderation alone should generate positive association of wages and participation. Our findings are most consistent with a persistent, positive labor supply shock at given working-age population in a cleared labor market. An alternative perspective of labor markets, the search and matching model, also points to the Hartz IV reforms as the central driver of the German labor market miracle.
