PRODUCTIVITY GROWTH AND WORKER REALLOCATION*
构建了一个增长与企业演化的均衡模型，阐明工人从低生产率企业流向高生产率企业如何推动整体生产率增长，并用丹麦企业数据验证了模型。
Productivity dispersion across firms is large and persistent, and worker reallocation among firms is an important source of productivity growth. An equilibrium model of growth and firm evolution designed to clarify the role of worker reallocation in the growth process is studied. We show that it explains the correlations between size measures and labor productivity found in Danish firm data. Conditions under which the reallocation of workers from less to more productive firms contributes to aggregate productivity growth in the economy modeled are derived. Finally, a proof of existence of an equilibrium solution to the model is also provided.
