국내 우유 가격 전이의 지역별 비대칭성 검정

Abstract

The purpose of this study is to verify what regional characteristics are in the process of transferring the raw milk producer price to the retail price of milk, and whether the introduction of the “raw milk price linkage system” affected the process. More specifically, it was intended to verify whether there is a long-term cointegration relationship between raw milk producer price and retail milk prices, regional differences in transition coefficients, regional differences in short-term adjustment to long-term equilibrium, and asymmetry in the price transition process. According to the results of the study, there are regional differences in the degree of transfer and adjustment process when the raw milk producer price is transferred to the retail price of milk, and there is also asymmetry in price transfer in regional milk markets. It was found that there is a difference in time lag in the price transfer according to regions. It was found that the speed of adjustment to price transfer and long-term equilibrium was greater in geographically highly competitive regions than in non-competitive regions.
