摘要:This paper analyzes the economic impact of a BSE outbreak in the U.S. on the Korean beef market, using social welfare analysis. Even though there has been no BSE case in Korea, the BSE case in the U.S. resulted in a significant impact on the Korean beef market. Previous studies focused on the impact of Foot and Mouth Disease (FMD) outbreaks in Korea in 2000 and 2002. In this welfare analysis the magnitude of demand shift and supply shift is critical but difficult to measure. The demand reduction is originated from consumers’ concern on food safety in the case of livestock disease. In this paper, the magnitude of demand shift is calculated monthly as the size of the error term in each month in a demand regression model.
