We study the distributional effects of a monetary policy-induced firm-level credit supply shock on individual wages and employment. To this end, we construct a novel dataset that links worker employment histories to firms' bank credit relationships in Germany. We document that firms in relationships with banks that were more exposed to negative monetary policy rates in 2014 see a relative reduction in credit supply. A negative credit supply shock in turn is associated with lower firm-level average wages and employment. These effects are concentrated among distinct worker groups within firms, with initially lower-paid workers more likely to be fired and initially higher-paid workers more likely to receive wage cuts. At the same time, wages decline by more at initially higher-paying firms. Consequently, wage inequality within and between firms decreases. Our results suggest that monetary policy has important distributional effects in the labor market.
