Multiproduct Firms and Product Turnover in the Developing World: Evidence from India
研究了印度在市场改革期间多产品企业的生产模式，发现产品更替尤其是产品合理化远不如美国常见，且与1991年贸易自由化后的关税下降无关，表明产业监管阻碍了资源有效配置。
This paper provides evidence on the patterns of multiproduct firm production in a large developing country, India, during a period that spans market reforms. In the cross-section, multiproduct firms in India look remarkably similar to their U.S. counterparts. The time-series patterns, however, exhibit important differences. In contrast to evidence from the United States, product churning, particularly product rationalization, is far less common in India. We find no link between product rationalization and output tariff declines following India's 1991 trade liberalization. The lack of "creative destruction" is consistent with the role of industrial regulation in preventing an efficient allocation of resources.
