Domestic and Foreign Price/Marginal-cost Margins: an Application to Spanish Manufacturing Firms

摘要

The authors investigate the differences in margins of export and domestic markets for Spanish manufacturing firms in the period 1990 to 1997. They estimate jointly a multiproduct cost function, a variable factor share equation, and two price/marginal-cost margin equations. The results indicate that the marginal cost of production sold in export markets is slightly greater than in domestic markets. At the same time, the price/marginal-cost margins in export markets are smaller than in domestic markets. There is also strong evidence that margins are procyclical in domestic markets, but this evidence is less clear in foreign markets. Copyright Blackwell Publishing Ltd 2004.
