Relação entre preço e custo marginal na indústria brasileira
Keywords:
mark up, production function, industrial sector.Abstract
The use of productivity measures based on the assumption of perfect competition to
evaluate public policies can lead to incorrect conclusions about them. In this sense,
the present research aims to analyze how far from perfect competition the Brazilian
industry is. The results indicated that the prices are, in general, 2.41 times marginal
cost, which shows that the perfect competition hypothesis is not valid for the Brazilian
industry and indicate that not considering the competition pattern lead to incorrect
conclusions. The forest and metallurgy sectors had the highest mark ups (3.81 and 2.95
respectively), and these results are robust to assumptions about scale economies and
different measures of mark up.
