Evaluating international price relationships using causal models
提出一种结合因果检验与路径分析的新方法，用于分析国际和国内农产品市场价格关系，并以乳制品国际价格为例展示其应用。
This study proposes and evaluates a new procedure for use in analysis of both international and domestic agricultural markets and prices. The method combines causality tests and path analysis. Causal models of international prices of dairy products are presented as empirical examples. Results have implications for both dairy market structure and competitiveness, and the robustness of Granger-type causality tests.
