Analyzing the pricing efficiency in spatial markets: Concept and application
提出一种基于格兰杰因果检验的方法来分析区域市场价格关系，避免了相关系数的模糊性，并应用于西德三个生猪市场的价格序列。
In this paper a technique is suggested for analyzing the price relationships between regional markets which avoids the ambiguity of the correlation coefficient. The method is based on Fama's concept of pricing efficiency and consists of tests included under the heading Granger Causality. The method is applied to price series from three regional markets for slaughter hogs in West Germany. The paper concludes with an evaluation of the suggested method.
