“…In 2015, average hourly productivity (as measured by GDP per hour per worker) in East Germany still fell short of West Germany's productivity by 23 percent while the gap in gross wages and salaries per hour per employee amounted to 20 percent. This partial catching‐up of East German wages and productivity towards West German levels is well documented (see, for instance, Aumann and Scheufele, ; Barrell and te Velde, ; Blien et al ., ; Franz and Steiner, ; Smolny, ; Steiner and Wagner, ), but the determinants of the persistent wage and productivity gaps between East and West Germany have been explored only to a limited extent. Investigations focus on firm‐level efficiency (Funke and Rahn, ), industry structure and establishment size (Görzig et al ., ), locational conditions (Kirbach and Smolny, ) or different wage‐experience profiles (see Gernandt and Pfeiffer, ).…”
