Market Integration, Demand, and the Growth of Firms: Evidence from a Natural Experiment in India

Working Paper: NBER ID: w24693

Authors: Robert T. Jensen; Nolan H. Miller

Abstract: In many developing countries, the average firm is small, does not grow and has low productivity. Lack of market integration and limited information on non-local products often leave consumers unaware of the prices and quality of non-local firms. They therefore mostly buy locally, limiting firms’ potential market size (and competition). We explore this hypothesis using a natural experiment in the Kerala boat-building industry. As consumers learn more about non-local builders, high quality builders gain market share and grow, while low quality firms exit. Aggregate quality increases, as does labor specialization, and average production costs decrease. Finally, quality-adjusted consumer prices decline.
