Abstract

In order to understand the impact of regulating bluefin tuna exports on the Japanese tuna market, we have to clarify the inter-species price relationship. This article investigates the market linkages among four tuna species, bluefin tuna, albacore tuna, bigeye tuna and yellowfin tuna, in Japan. Vector autoregressive distributed lag (VARDL) model is used to simulate the impact of a decrease in the bluefin tuna supply on the price of bluefin tuna and other species. The result is that regulating bluefin tuna exports raise only the price of bluefin tuna but have little impact on the prices of other tuna species.
