On Input Market Frictions and Estimation of Factors' Demand

Abstract

In this paper we explore the impact of imperfectly competitive input markets on production function estimation. First order prot maximizing conditions are altered when frictions in input markets cause the elasticity of input supply to the firm to be nite. A consequence of this is that the standard econometric model used for production function estimation will be misspecified. We prove that, in all non trivial cases, finite elasticities of supply to the firm will lead to inconsistent estimates of production function parameters. Monte Carlo simulations show that the resulting bias can be economically significant.
