Davide Luparello from Penn State will present "Why Do Contract Workers Earn Less? Evidence from India’s Auto Industry"

Abstract: Contract workers constitute half of employment in India’s automotive industry but earn substantially less than permanent workers. Using data from the Annual Survey of Industries (2002-2019), I develop an estimator of labor supply and demand schedules to explain this wage premium. The model features nested CES production with distinct worker types, discrete choice supply functions with worker type-specific wage sensitivity, and differentiated market conduct—Nash-Bertrand competition for contract workers versus plant-level union bargaining for permanent workers. I find that the wage premium stems entirely from permanent workers’ higher productivity rather than differential monopsony power or unionization advantages.
