Firm Entry and Exit and Aggregate Growth
利用智利和韩国工厂数据，发现GDP快速增长时期企业进入退出对总体生产率增长的贡献更大，并通过模型分析降低进入成本或技术采用壁垒会增强这一关系。
Applying the Foster, Haltiwanger, and Krizan (2001) decomposition to plant-level manufacturing data from Chile and Korea, we find that the entry and exit of plants account for a larger fraction of aggregate productivity growth during periods of fast GDP growth. To analyze this relationship, we develop a model of firm entry and exit based on Hopenhayn (1992). When we introduce reforms that reduce entry costs or reduce barriers to technology adoption into a calibrated model, we find that the entry and exit terms in the FHK decomposition become more important as GDP grows rapidly, just as they do in the data from Chile and Korea.
