Zusammenfassung: 
This paper investigates whether workers' bargaining power, which extends beyond union membership to collective wage agreements in Germany, affects the level and distribution of wages at the regional level. We conduct fixed-effect regression analysis and a DFL decomposition on SOEP data from 2014 to 2021 and find, first, that both collective wage agreements and union membership statistically and economically significantly raise wage levels at the national level. Second, and importantly, this effect is regionally heterogeneous: Collective wage agreements continue to be linked to higher wages at the regional level, whereas the relationship is weakened or disappears altogether for union membership. Third, collective wage agreements go along with lower overall wage inequality, while union membership compresses wage inequality mainly at the lower end of the distribution.
