AB This article studies the behavior of input cost shares, in an environment where labor is costly to variate, materials can variate at no cost and capital is fixed. A model relating cost shares with relative prices and adjustment costs is proposed, allowing joint estimation of the elasticity of substitution and the adjustment cost function, which is an unknown function of the capacity utilization. Based on a panel of more than 700 manufacturing firms we find evidence of strong input share variations according to the degree of capacity utilization. The estimated shapes of adjustment costs of labor are in agreement with our theoretical model, and we obtain sensible elasticities of substitution estimates.Based on such estimates, we find evidence of a negative (positive) bias in downturns   (recoveries) in conventional productivity growth measures.
