英文文献：Dynamics Of Polish Wheat Prices In Comparison To Selected World Prices In A Period Of Economic Transformation
英文文献作者：Figiel, Szczepan
英文文献摘要：
Poland's market reforms implemented in 1990 should possibly result in increasing price linkages between Polish and internationally traded agricultural commodities like wheat. Using regression and cointegration analysis Polish monthly wheat prices were found to be generally unrelated to selected world prices over the period of 1990/91 through 1996/97 mainly because of Polish government's intervention.
