“…In the case of salmon, for example, farmed and wild-caught product are found to be close substitutes, and increased production of farmed salmon has had a substantial impact on the market and prices for wild salmon species (Knapp, Roheim, and Anderson 2007;Nielsen et al 2007;Nielsen et al 2011). This article follows these previous studies and others that identify interactions among seafood products in the market (Gordon and Hannesson 1996;Jaffry, Pascoe, and Robinson 1999;Nielsen, Smit, and Guillen 2012;Singh, Dey, and Surathkal 2012), but we extend the cointegration analysis in this area by explicitly accounting for structural breaks. Despite the vast literature on the use of unit root tests in the presence of structural breaks, there are only a small number of multivariate cointegration analyses that address the issue of breaks in time series data.…”
