AN EMPIRICAL ANALYSIS OF INTERREGIONAL PRICE LINKAGES*
使用向量自回归模型分析德克萨斯州、伊利诺伊州玉米价格与新奥尔良出口价格的关系，发现出口市场对美国国内市场的价格影响日益增强。
ABSTRACT Vector autoregression models are used to analyze the relationships between Texas and Illinois corn prices, and the New Orleans export price. Decomposition of error variances suggests an increasing exogeneity in the recent years between the export market and the two U.S. markets. Impulse response functions indicate that the export price influences both the Illinois and Texas prices.
