Declining Business Dynamism: What We Know and the Way Forward
综述美国经济活力下降的证据，涵盖就业流动、创业减少等趋势，并基于企业动态模型分析生产率与就业增长的关系，提出可检验的解释。
A growing body of evidence indicates that the U.S. economy has become less dynamic in recent years. This trend is evident in declining rates of gross job and worker flows as well as declining rates of entrepreneurship and young firm activity, and the trend is pervasive across industries, regions, and firm size classes. We describe the evidence on these changes in the U.S. economy by reviewing existing research. We then describe new empirical facts about the relationship between establishment-level productivity and employment growth, framing our results in terms of canonical models of firm dynamics and suggesting empirically testable potential explanations.
