Este estudo tem como objetivo realizar uma análise empírica da estrutura dos custos de ajustamento do emprego industrial. Para tanto, estima-se um modelo dinâmico de demanda por trabalho que contempla custos de ajustamento quadráticos e custos de ajustamento fixos como casos particulares. A metodologia traz um teste de hipótese de coeficientes do modelo de regressão que permite identificar o tipo de custo de ajustamento do emprego mais apropriado. A partir de microdados de empresas industriais do Rio Grande do Sul, os resultados obtidos sugerem que um modelo misto, em que custos de ajustamento quadráticos e custos fixos são considerados, representa melhor a estrutura de custos de ajustamentos. A elasticidade emprego-salário condicional foi estimada entre –0,4 e –0,8, com valores similares e positivos para a elasticidade emprego-produto. O tempo mediano de ajustamento a choques varia de um a dois anos. Manufacturing employment and adjustment cost at firm level: an analysing using microdata :: We provide an empirical analysis of the structure of adjustment in manufacturing employment using Brazilian firm data. A general dynamic labor demand model is estimated including quadratic and fixed adjustment costs as particular cases. A hypothesis test based on regression model coefficients allows differentiating which of the type adjustment cost is more appropriate. Based on micro data on manufacturing firms in Rio Grande do Sul, the results suggest that a model with both quadratic and fixed costs represent the adjustment costs for manufacturing. The long run employment wage elasticity estimates range from –0.4 to –0.8 with similar positive values for the output elasticity. The median shock adjustment length varies from one to two years.
