  Citation × Citation Citation Abstract Copy Title: Investigating Salmon Price Volatility Author: Sikveland, Marius, Oglend, Atle An understanding of the structure of price volatility is of great interest since this is a major contributor to economic risk in the salmon industry. The volatility process in salmon prices was analyzed based on weekly price data from 1995 to 2007. The Generalized Autoregressive Conditional Heteroskedasticity (GARCH) model was used to test for volatility clustering and persistence of volatility for prices. We find evidence for and discuss the degree of persistence and reversion in the salmon price volatility. We further find that the usual assumption of an independent zero mean normally distributed error term is not satisfactory when describing the salmon price process.

  Citation × Citation Citation Abstract Copy Title: The Halo Effects of Norwegian Salmon Promotion on EU Atlantic Salmon Demand Author: Myrland, Oystein, Xie, Jinghua The Differential Almost Ideal Demand System (AIDS) is estimated to exam the direct and spillover responses for salmon promotion conducted by the Norwegian Seafood Export Council in EU Atlantic salmon market. The model allows the advertising effect on demand curve to shift and rotate simultaneously. EU demand is segmented by country of origin, namely Norway, Chile, United Kingdom, Canada, and Rest of World. Results suggest that Norwegian advertising shifted its own demand curve rightward and curve of Rest of World leftward and counterclockwise rotated the curve of UK. The advertising-induced demand curve rotation is found to be important for marginal benefit-cost ratio and producer surplus measurement. A tiny change of price elasticity causes a substantial change of marginal benefit-cost ratio and a not tiny change of producer surplus.

  Citation × Citation Citation Abstract Copy Title: Does the Recreational Angler Care? Escaped Farmed Vs Wild Atlantic Salmon Author: Liu, Yajie, Olaussen, Jon Olaf The paper explores to what extent escaped farmed salmon from fish farms affect the willingness-to-pay for recreational fishing of Atlantic salmon in Norwegian rivers. The aim is to quantify the potential externality from escaped farmed species working through the demand for the natural stock of congeners. While the biological and genetic effects of escaped farmed salmon have been widely acknowledged, the potential economic consequences have received little attention. This study is a first attempt to close this gap by analysing the direct effect on the recreational use values. The empirical analysis is based on the results from a contingent valuation survey conducted in Norway. It is found that the presence of escaped farmed salmon in Norwegian rivers may have severe economic consequences on the willingness-to-pay for recreational fishing.

  Citation × Citation Citation Abstract Copy Title: Market Interactions between Aquaculture and Common-Property Fisheries: Examining the Empirical Evidence from the Bristol Bay Sockeye Salmon Fishery in Alaska Author: Valderrama, Diego, Anderson, James The impressive growth of world aquaculture has led to profound transformations in the economic structure of several capture fisheries. Evidence from the Alaska salmon fisheries supports this argument as a connection has been suggested between the recent trends of declining ex-vessel prices and the rapid development of salmon farming elsewhere in the world. In Bristol Bay, home of the largest sockeye salmon runs in the globe, participation in the limited-entry fishery has declined by approximately 20% since 2001. Likewise, permit market values have plummeted to historic low levels, with economic conditions not likely to improve significantly in the mid-term future. To examine this problem, we develop a formal analytical framework for the study of market interactions between a limited-entry fishery and an aquaculture sector. We adapt the model of regulated open-access developed by Homans and Wilen to examine the implications of aquaculture development on the actions of fishermen and the regulatory sector in a restricted-access setting. Results indicate that the emergence of a low-cost aquaculture sector brings about important structural changes in the restricted-access fishery, rendering limited-entry regulations irrelevant as participation rates decline due to the falling prices. An important implication is that, despite the limited-entry constraint, the fishery moves to an institutional arrangement closer to regulated open access, with resource rents drastically reduced. Model predictions are compared with the empirical evidence available from the Bristol Bay sockeye fishery. The advantages of cooperative management relative to the current competitive structure of the fishery are highlighted.
