This paper investigates the degree of market integration between several product forms of US wild salmon and Norwegian farmed salmon. While several studies have investigated the link between farmed salmon and fresh and/or frozen wild salmon markets, we expand the literature with the inclusion of the products canned salmon and salmon roe. Understanding how canned salmon and salmon roe are related to the broader salmon market is of importance to US fisheries, as these products are high-price exports for the United States. Our results find evidence of cointegration between the Norwegian farmed salmon market and all US salmon products. Domestic and international economic conditions, such as production technological advances within farmed salmon production, environmental challenges, and changes in trade regulations, which affect the market for farmed salmon, will hence also influence US prices of frozen and canned salmon, as well as salmon roe.

The purpose of this paper is to test for price linkages among European (France, Germany, and U.K.) and U.S. prices of whole fresh cod and frozen cod fillets. In testing for a cointegrated system, we use both the two-stage Engle-Granger and Johansen procedures. Short-run price dynamics are measured using an error-correction model. Based on monthly import price observations from 1980 to 1992, the empirical results show no long-run price relationships for fresh cod between European and U.S. markets, but we do measure long-run price linkages for frozen cod fillets. Within Europe the markets for both fresh and frozen cod product are well integrated. The U.S. fresh cod market is distinct and separate from European markets, while the U.S. frozen cod market shows no short-run links to European markets. There is weak evidence for a long-run international market in frozen cod fillets. [ABSTRACT FROM AUTHOR]
