Considerações sobre o nível ótimo de mark-up implícito num regime de concorrência

Abstract

The profit maximizing theory of the competitive firm in the short run is presented as a funtion of its cost structure and the optimal level of implicit mark-up. Then, several well-known relationships of the neoclassical theory are expressed using the notion of optimal level of implicit mark-up. Finally, some of the previous results are used to explore - as a first approximation - three hypoteses concerning the expected mark-up variations along the cycle. The preliminary conclusion favors the anti-cyclical hypothesis.
