Aim of the study Is to find out if the prices of imported salmon and domestic wild salmon and farmed salmon trout are co-integrated, i.e. do they belong to the same market? IIFET 2002, Wellington
Growing salmon market IIFET 2002, Wellington
Prices converge in the 1990’s IIFET 2002, Wellington
Monthly real prices of domestic salmon trout and wild salmon and imported salmon in IIFET 2002, Wellington
Monthly quantities of domestic salmon trout and wild salmon and imported salmon in IIFET 2002, Wellington
Co-integration analysis Data tranformations Johansen test Co-integration Exclusion tests Weak exogenity test Stationarity Deflation (CI) Logarithms Unit root tests (ADF) Are all price series co- integrated? Causality IIFET 2002, Wellington
Studied time series Time series: Prior EU Post EU (6)Prior MIP 1997 (7) Post MIP (6) Time of radical change IIFET 2002, Wellington
Results unit root tests All the tested series were non-stationary at the levels and their first difference was stationary, and can be included in co-integration tests One exception: Rainbow trout IIFET 2002, Wellington

Conclusions There is a long-run relationship between the prices of domestic salmon trout, wild salmon and imported salmon Changes in prices of imported salmon and salmon trout affect quickly to the price of wild salmon The price of imported salmon influence the price of salmon trout: They are substitutes, even not perfect ones The results of imported salmon and salmon trout are sensitive to the period investigated IIFET 2002, Wellington
Conclusions Why not co-integration all the time: Not same fish species - not perfect substitutes Salmon has an effect on salmon trout - not the other way around Structural changes: changes in value chain - concentration changes in use of salmon trout from fresh to processed products EU and MIP IIFET 2002, Wellington
