Causality in demand: a co-integrated demand system for trout in Germany

Examining the Long-Run Relationship between the Prices of Imported Abalone in Japan

“…This rapid increase in the production of farmed abalone products is of concern for wild abalone producers because of its presumed direct contribution to the downward price trend. Decreased price of wild product has been observed in some other seafood products, such as salmon, where supply has increased through aquaculture (Knapp, Roheim, and Anderson 2007;Nielsen et al 2007;Nielsen et al 2011). However wild and farmed abalone have many distinct market traits, including size and color, so there is debate within the Australian wild harvest sector surrounding the strength of the effect of increased aquaculture supply on price.…”

“…The evidence from the literature indicates low substitution between wild and farmed fish, unless they are closely related species. 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.…”

Restructuring European freshwater aquaculture from family-owned to large-scale firms - lessons from Danish aquaculture

“…Girag () concludes that farmed trout in Germany with white meat does not seem to compete closely with other fish species. Nielsen, Jensen, Setälä and Virtanen (), however, identify substitution, although very loose, between frozen trout with white meat in Germany and imported cod, suggesting that trout in Germany might be loosely connected to the large European whitefish market. The result of this market structure is limited competition and product development.…”

Price formation and geographic market integration: An empirical investigation of Adriatic small pelagic species

“…Following this argument, and considering that our analysis is limited to a 5-year period, we hypothesise that supply is exogenously determined and that price represents the dependent variable (see Asche and Hannesson, 2002;Jaffry et al, 2005;Nielsen et al, 2009). It is therefore correct to apply an inverse demand model that can be written, in a generalized functional form, according to the following equation:…”
