Multi-product Firms And Product Turnover In The Developing World: Evidence From India
Recent theoretical work predicts that an important margin of adjustment to deregulation or trade reforms is the reallocation of output within firms through changes in their product mix. Empirical work has accordingly shifted its focus towards multi-product firms and their product mix decisions. Existing studies have however focused exclusively on the U.S. Using detailed firm-level data from India, the authors provide the first evidence on the patterns of multi-product firm production in a large developing country during a period (1989-2003) that spans large-scale trade and other market reforms. They find that in the cross-section, multi-product firms in India look remarkably similar to their U.S. counterparts, confirming the predictions of recent theoretical models. The time-series patterns however exhibit important differences.
