This study examines the effects of the introduction of a statutory minimum wage in Germany on hourly wages, monthly wages and paid working hours. We exploit a novel panel data set by linking the Structure of Earnings Survey (SES) 2014 and the Earnings Survey (ES) 2015 and apply a difference in differences approach at the establishment-level. The advantages and limitations of this approach are discussed in comparison to previous studies, which showed mixed results regarding minimum wage effects on earnings. The results indicate an effect of the introduction of the statutory minimum wage on hourly wages of about 13 percent. Due to negative effects on working time of about minus 6 percent, the effects on monthly gross earnings are smaller, but still amount to approximately 8 percent. The minimum wage has been particularly effective in raising monthly earnings of low-wage workers in part-time jobs and in eastern Germany. We hence provide new insights to the debate about the existence and size of minimum wage effects on earnings and working time and its political implications.
