Abstract

This study aimed to explore the price pass-through effect among international grain price fluctuations, large pig feed prices (LPFP), and pig prices (PIGP). A DCC-GARCH model was applied as the estimation and data analysis method to study the sampling monthly data, dated from 2000 to 2009, to estimate the infl uential relationships among the three areas studied. Results suggested that the international grain price has a positive direct pass-through effect on LPFP, and an indirect pass-through effect on PIGP. LPFP has a mutual direct passthrough effect on PIGP and price fl uctuation, while price fluctuations of LPFP and PIGP result in a short-term impact. The understanding of the pass-through effect between international grain price fluctuations and the LPFP and PIGP in Taiwan can provide a reference to relevant organizations, pig farmers and dealers in price information and decision-making.
