Estimating Structural Change in the Japanese Beef Import Market in the Wake of BSE: A Smooth Transition Approach
JOURNAL OF AGRICULTURAL AND RESOURCE ECONOMICS(2022)
摘要
We assess the effect of bovine spongiform encephalopathy (BSE) on Japanese beef imports from the United States and competing suppliers. Using a source-differentiated almost ideal demand system of beef imports with endogenous smooth transition functions, we find that a nonlinear structural change has occurred in the Japanese beef import market in the wake of BSE. The BSE outbreaks led an instantaneous, persistent impact on Japanese beef imports lasting over a decade, causing a significant shift in Japanese consumer preferences for beef imports from different origins. Over half of the estimated expenditure, own-price, and cross-price elasticities have changed in the aftermath of BSE, and some have not returned to their pre-BSE levels even after the trade recovery period.
