11 pages, In this paper, we investigate the interdependence among changes in the prices of beef, pork, and chicken in Japan using a time-varying coefficient vector autoregressive model. Our empirical analysis using monthly data from January 1990 to March 2014 shows that changes in beef prices have long-term influences on changes in pork and chicken prices. Moreover, current changes in the prices of beef, pork, and chicken are closely related to changes in their prices in the preceding two months. Additionally, we do not find that the bovine spongiform encephalopathy outbreak announced by the Japanese government in September 2001 had a long-term influence on the dynamic relationships among changes in the prices of beef, pork, and chicken in Japan.
Via online journal., Recent developments in shrimp culture have resulted in the entry of high-quality, lower priced shrimp into the Japanese market, displacing the Australian product from its previously competitive position. The response of producers in Australia has been to form the Australian Prawn Promotion Association (APPA). An inspection of the literature suggests that demand-, product-, market-, and producer-related factors are thought necessary for successful promotion of agricultural and seafood products. In an attempt to analyze these factors, research was conducted in Japan in April and August 1991. Information for the study was gained from a review of the available literature and from interviews with the staff of a wide cross-section of companies and other organizations involved in the Japanese shrimp industry. It was found that: 1. the prospects of an APPA-style promotional campaign aimed at reducing the price elasticity of demand appear poor, and 2. there are few opportunities to differentiate Australian product effectively.
