概要 |
In this paper, we examine the evidence of asymmetric price transmission in several important US agricultural markets. We use estimated asymmetric error correction models (ECM) for producer, wholesale..., and retail prices to test the presence of asymmetric price transmission. Following several other studies reported in this literature, we find mixed evidence of the phenomenon across the candidate markets. We then summarize the test results by conducting a meta-analysis of the p-values associated with the observed asymmetry test statistics. We find that the p-values associated with the beef market are significantly less than the base markets, and there is evidence that the test p-values are slightly higher in later years (since 1990).続きを見る
