Productivity dynamics among union locals in the United States
利用美国工会地方组织的面板数据，研究工会间竞争对地方组织生产率和生存的影响，发现竞争未能有效提升生产率，创造性破坏效应微弱。
Abstract Using panel data on union locals in the United States we examine the dynamics of the union sector, investigating the impact of inter‐union competition on locals' productivity and survival. We find low entry rates, high exit rates and high levels of productivity dispersion in the sector. The entry of new locals is not associated with productivity improvements among incumbents but has a small negative association with locals' survival rates. These findings indicate that inter‐union competition is not effective in raising productivity and the effects of creative destruction are weak, with these processes likely insufficient to stem the sector's overall decline.
