英文文献：Domestic and foreign price-marginal cost margins: An application to Spanish manufacturing firms-国内外价格边际成本边际:西班牙制造企业的应用
英文文献作者：Lourdes Moreno Martín,Diego Rodríguez Rodríguez
英文文献摘要：
The objective of this paper is to analyse the differences in price-marginal cost margins of the export and domestic markets by the estimation of a multiproduct cost function. We apply this method to a panel of Spanish export manufacturing firms from the period 1990-1997. Some results emerge from the estimations. First, price-marginal cost margins in domestic markets are larger than foreign margins throughout the period. Second, price-marginal cost margins are procyclical in the domestic market but there is no evidence of this behaviour in the foreign markets. Third, there is no evidence that export firms used the devaluation of the currency to increase their margins. Finally, price-cost margins reveal some degree of heterogeneity across industries in both markets.
本文的目的是通过估计一个多产品成本函数来分析出口市场和国内市场的价格边际成本差额。我们将此方法应用于1990-1997年期间的西班牙出口制造公司。从估计中可以得到一些结果。首先，在整个时期内，国内市场的价格边际成本利润率大于国外市场的边际成本利润率。第二，价格-边际成本边际在国内市场上是顺周期的，但在国外市场上没有这种行为的证据。第三，没有证据表明出口公司利用货币贬值来增加利润。最后，价格成本利润率显示出两个市场中不同行业之间存在一定程度的异质性。
