Management practices, competition, and multi-product firms in developing countries

We study how liberalization and competition affect firms' output and product scope depending on management practices. In a model of multi-product firms, we show that firms with better management practices specialize in fewer products with lower marginal costs. The model predicts that, under increased competition, firms with better management practices are less adversely affected by competition, especially in heterogeneous sectors. Evidence from India's de-reservation policy supports these predictions. Our simulations estimate a 0.29% welfare gain in India from the policy. The same policy could increase welfare by 0.39% in an environment with better management practices, such as the US, highlighting the management practices' role in liberalization outcomes.
