本文考察了1972年至1988年期间美国制造业14000多家工厂的生产率、投资和工厂年龄之间的关系。由于植物的异质性,生产力模式存在显著差异。最初,生产力随着植物年龄的增长而增加,但随后下降。生产率和生产率的增长被发现与工厂规模和行业有系统的相关关系。然而,投资与生产率或生产率增长之间实际上没有可观察到的关系。总体而言,研究结果表明,植物异质性和固定效应比沉没成本或资本再分配更重要地决定了可观察到的生产力模式。
This paper examines the relationship between productivity, investment, and plant age for over 14,000 plants in the U.S. manufacturing sector for the period of 1972 to 1988. Productivity patterns vary significantly due to plant heterogeneity. Initially productivity increases with respect to plant age, but then it decreases. Productivity and growth in productivity are found to be systematically correlated with plant size and industry. However, there is virtually no observable relationship between investment and productivity or productivity growth. Overall the results indicate that plant heterogeneity and fixed effects are more important determinants of observable productivity patterns than sunk costs or capital reallocation.
