Abstract

This paper aimed to analyze the price transmission and marketing margins among the segments of beef production chain (farm, wholesale and retail), looking for evidence of possible exercise of market power. Two Vector Error Correction models were estimated based on Houck’s framework. The results indicate symmetry in price transmission between wholesale and retail and price asymmetry between wholesale and producer. Thus, there is some evidence of the possible exercise of market power only from downstream to upstream (from wholesale to producer). This may be explained by differences in market structure, as retail and wholesale are oligopolies, unlike producers.

用VEC模型分析价格传递的不对称:在牛肉生产链中的应用

本文旨在分析牛肉生产链(农场、批发和零售)各环节之间的价格传递和营销边际，寻找市场力量可能发挥作用的证据。基于Houck的框架估计了两个矢量误差修正模型。结果表明，批发与零售之间的价格传导是对称的，批发与生产者之间的价格传导是不对称的。因此，有一些证据表明，市场力量可能只从下游到上游(从批发到生产商)行使。这可以用市场结构的差异来解释，因为零售和批发都是寡头垄断，不像生产者。

期刊介绍： The journal Economia Aplicada (Brazilian Journal of Applied Economics) is a quarterly publication of the Dept. of Economics of the Faculty of Economics, Business and Accounting of the University of São Paulo at Ribeirão Preto (FEA-RP/USP). It was first published in 1997 by the Dept. of Economics of FEA-USP and by FIPE, with the primary concern of filling an editorial gap in Brazil. The Journal"s interest is to publish solely scientific papers on applied economics. Nowadays it has the same goal. Its focus is to publish papers with economic analysis applied to specific problems of interest either to public or private sector, especially with quantitative results bringing theory and reality closer.
