The paper presents micro evidence on firm dynamics for enterprises in Indian Manufacturing sectors on the grounds of Prowess database provided by the Centre for Monitoring Indian Economy (CMIE) covering the period 1991-2010. The parameterization of the distributions of growth exhibit high level heterogeneity displayed among firms even within the same sector, which widens over time. The transition probabilities matrix reveals the coexistence of firms with very different characteristics and performance within sectors. Given the wide heterogeneities, the paper resorts to quantile regression to identify the differential effect of regressors at different deciles of the conditional distrubution.

Abstract "Learning-by-doing" is usually identified as a process whereby performance increases with experience in production. The paper investigates different patterns of "learning by doing", studying learning curves at product level. Cost-quantity relationships differ a lot across products belonging to sectors with different "technological intensities". Moreover, such differential patterns are affected by firm spending on research and capital investments. Finally, our evidence suggests that "learning", or performance improvement over time is not a by-product of the mere repetition of the same production activities, as sometimes reported in previous studies, but rather it seems to be shaped by deliberate firm learning efforts and by the interactions among firms themselves.
