This paper addresses the importance of different product forms and their origin when considering the market structure in the European salmon market. The competition between farmed salmon and wild caught Pacific salmon has received some attention previously. However, this was before frozen Atlantic salmon emerged as an important product form in the market. This could be important as frozen Atlantic salmon is more likely to be a close substitute for Pacific salmon, which is mostly marketed frozen, than is fresh Atlantic salmon. In this paper, an almost ideal demand system is used to estimate the demand for fresh Atlantic salmon, frozen Atlantic salmon and frozen Pacific salmon in the European Union.  相似文献

The food incidence of polychlorinated biphenyls in farmed Atlantic salmon in Canada and its subsequent effects on the demand for farm-raised salmon has induced policymakers and stakeholders to develop new policies on food safety. This article analyzes consumer attitudes toward mandatory traceability and labeling systems for farmed Atlantic salmon in Newfoundland and Labrador. It identifies factors affecting consumers' decisions to purchase the product. Results show that consumers, on average, perceive the benefits of traceability and labeling systems on farm-raised Atlantic salmon in spite of its driving up the product price.  相似文献

Commercial aquaculture, the cultivation of fish in managed systems, has received increasing attention in recent years as an alternative source of fish, employment and income. High value species particularly offer a better prospect of profitable farming. For example, Atlantic salmon, which is one of the more expensive species on the market, is now being farmed in Norway, Scotland, Canada, the United States, and several other countries. Norway has made rapid progress in Atlantic salmon aquaculture; farmed salmon have now replaced cod as her principal export species. In the opinion of some observers, Norway' s success in farming the Atlantic salmon is the most significant event in the history of European aquaculture (United States Department of Commerce, 1984).
Commercial aquaculture in Canada is still in its initial stage of development, but recently there has been increased interest in aquaculture as a means of generating incomes and jobs, and of acquiring technological expertise. The Science Council of Canada has urged a commitment towards commercial aquaculture; it cites Norwegian aquaculture that by the year 2000 could be producing fish worth U.S. $3 billion and be employing 50.000 people (Science Council of Canada 1985). In Canada, farming of Atlantic salmon is expanding rapidly on both east and west coasts. Canada' s output of farmed Atlantic salmon reached 174t in 1984 and is forecast to reach 1,200t by 1987, with a further immediate potential on the east coast of 2.000–3,000t. On the west coast, more than a million Atlantic salmon eggs have been imported for hatching and for cultivation in sea pens. The number of Atlantic salmon farms on the west coast is projected to more than double by the end of 1986.  相似文献

Due to the successful development of Norwegian salmon farming, major salmon producing countries (such as Canada, the United States, Japan, Chile, Scotland, etc.) have actively attempted to duplicate this practice. This recent development has far reaching implications for the salmon industry. Therefore, a demand analysis of Atlantic salmon products is timely. While we applaud the work by Kabir and Ridler (hereafter, KR), we would like to comment on the specification of their econometric model and elaborate on the implications of KR's findings on fishery management.  相似文献

This paper estimates values for a few important parameters related to the Atlantic salmon market in Canada. Included among the estimated parameters are income and price elasticities of demand. Many economists are currently engaged in the study of economic feasibility of farmed Atlantic salmon in Canada. In these studies forecasts of demand for Atlantic salmon play a crucial role. Since there are no serious studies on relevant elasticity estimates, the researchers have so far relied on extrapolations of historical time series data on demand (see, for example, Marine Science Research Laboratory (198O), Ridler (1983)). In this study we have formulated and estimated demand equations for Atlantic salmon using Canadian data covering the period between 1955 and 1981. We have found a very high value for both price and income elasticities of demand. High elasticity values have interesting implications for salmon farming. The domestic market can absorb additional supplies for Atlantic salmon. A high price elasticity guarantees that there is scope for salmon fishermen to increase their revenue by selling a higher volume in the Canadian market. The value of income elasticity suggests that Atlantic salmon is a strongly superior good. Various pressure groups in Canada and elsewhere have been claiming that Atlantic salmon is an endangered species and restrictions on catches must be imposed to save the species from total extinction. Implications of such controls have been analyzed in the light of the calculated value of the elasticities. Cet article fait une estimation de valeurs pour quelques paramètres importants reiatifs à la vente du saumon de l'Atlantique au Canada. Re-venus et élasticité des prix à la demands sont inclus parmi les paramétres étudiés. Un certain nombre d'économistes étudient en ce moment l'-aspect économique de I'implantation d'élevages de saumon de l'Atlantique au Canada. Dans ces études les previsions portant sur la demande jop-uent un rolê-clé. Etant donné qu'il n'y a pas d'études sérieuses sur les estimations d'élasticité, les chercheurs se sont appuyésA jusqu'ici sur des extrapolations à partir de séries de données historiques sur la demande. Dans cette étude nous avons formulé et estimé des équations de demande pour 1e saumon de l'Atlantique qui utilisent des données canadi-ennes entre 1955 et 1981, Nous avons trouvé une très naute valeur pour l'éasticitéà la fois des pris et des revenus. La haute élasticité des valeurs a des implications intáressantes pour l'élevage du saumon. Le marché domestique peut aisément absorber une quantité supplémentalre de saumons. Une élasticité dans la gamine élevée des prix permet de garan-tir aux éleveurs de saumon une augmentation de leurs revenus par la vente d'un volume accru sur le marché canadien. La valeur de l'élasticité du revenu suggère que le saumon de l'Atlantique est une denrée su-périeure et qu'avec une augmentation du revenu réél per capita, la demande domestique augmentera à un rythme plus rapide. Plusieurs groupes de pression au Canada et ailleurs soutiennent que le saumon atlantique est une espèce en danger et que des restrictions sur les prises doivent Ctre imposées pour sauver ces espèces d'une extinction totale. Les implications de ce genre de contrôle ont áté ana-lysées à la lumière de la valeur calculée ces élasticités.  相似文献

Import demands for Atlantic and Pacific salmon are estimated for Japan, the European Community and North America. Cross-price elasticities indicate that wild high-valued Pacific salmon (chinook. coho and sockeye) and farmed Atlantic salmon are substitute goods in the marketplace. This finding implies that movements in the prices of both fanned and wild salmon can be caused by supply or demand changes in the market for either type of salmon. This result in turn has important implications for future markets and prices of fanned and wild salmon in Canada and the United States La demande à l'importation pour le saunion de l'Atlantique et du Pacifique esl eslimée pour le Japon, la CEE et l'Amerique du Nord. Les valeurs d'elaslicité croisée montrenl que le saumon “sauvage” du Pacifique hautement prisé (chinook, coho et sockeve) et le saumon d'elevage de l'Atlantique peuvent se substituer l'un à l'autre sur le manhé. Cette consultation signifie quedes mouvements dans les prix des deux types de saunion peuvent étre causés par des fluctuation de l'offre et de la demande affectant l'un ou l'autre type. Cela comporte d'imponantes répercussions pour I'avenir sur le manhé el sur les prix du saumon tant sauvage que d‘élevage au Canada et aux États-Unis  相似文献

The Atlantic salmon has been harvested by both commercial and recreational fishers for many years on the river systems of the province of New Brunswick on Canada 's Atlantic coast. The commercial fisheries were closed and controls were placed on the recreational fisheries following the 1983 collapse of the salmon stocks. This management policy remains in effect. A preliminary analysis using a linear control model showed this to be an economically efficient harvest allocation policy on New Brunswick's Miramichi River. The analysis is extended to the more realistic nonlinear framework here to determine whether the harvest allocation decision would be significantly changed. Both fisheries are found to generate positive net economic benefits, although the recreational fishery is determined to be more valuable than the commercial fishery. Permanent closure of the commercial fishery is not indicated.  相似文献

A simultaneous-equation model of the demand and supply of Norwegian Atlantic salmon in the United States and the European Community is constructed, and sensitivity analyses are conducted to measure the effects of changing exchange rates, the Norwegian supply of Atlantic salmon, and prices of North American Pacific salmon. Using monthly statistics from January 1983 through March 1987, the demand for Norwegian Atlantic salmon is found to be highly seasonal, and highly price and income elastic in the United States and the European Community. Chinook is found to be a weak substitute for Norwegian Atlantic salmon in the U.S., and frozen chinook, sockeye and coho in the European Community are also found to be weak substitutes for Norwegian Atlantic salmon. Nous avons élaboré un modéle à équations simultanées de la demande et de ?approvisionnement pour le saumon de ?Atlantique provenant de Norvège, aux États-Unis et dans la Communauté européenne, et nous avons precédé à des analyses de sensibilité afin de mesurer les effets de la variation des taux de change, des approvisionnements de saumon de ?Atlantique de Norvège et des prix du saumon du Pacifique provenant ?Amérique du Nord. En nous fondant sur les statistiques mensuelles recueillies de Janvier 1983 à mars 1987, nous avons constaté que la demande de saumon de ?Atlantique provenant de Norvège est extrêmement saisonnière et qu'elle est élastique par rapport aux prix et aux revenus, aux États-Unis et dans la Communauté européenne. Le saumon quinnat (chinook) s'est avéré un piètre produit de remplacement du saumon de ?Atlantique provenant de Norvège dans la Communauté européenne.  相似文献

Two demand models of recreational participation and site choice are developed: an alternatives model and an expenditures model. Both assume maximization of utility over the year, so allow for diminishing marginal utility. They do not impose the restrictive assumption that where one goes on a trip is independent of where one plans to go on other occasions. Estimation is with a nested constant-elasticity-of-substitution preference ordering: it is relatively easy to estimate because of global regularity, it allows sites to be complements, and it has the potential to be locally flexible. The application is to Atlantic salmon fishing.  相似文献

This paper measures and assesses the variation in total factor productivity (TFP) growth among Canadian provinces in crops and livestock production over the period 1940–2009. It also determines if agricultural productivity growth in Canada has recently slowed down as indicated by earlier studies. The paper uses the stochastic frontier approach that incorporates inefficiency to decompose TFP growth into technical change (TC), scale effect (SE), and technical efficiency change. The results indicate that productivity changes were mainly driven by TCs for crops, while the productivity changes in livestock was mainly driven by SEs and technical progress. Though change in technical efficiency is mainly positive (except for New Brunswick and Nova Scotia), its contribution to productivity growth was very little for the provinces. We also found that over the entire period, the productivity growth rates for the crop subsector are on average higher for the Prairie provinces than for the Eastern and Atlantic provinces. On the other hand, the productivity growth rates in the livestock subsector are on average higher in the Eastern and Atlantic provinces than in the Prairie region with the exception of Manitoba. Finally, we found that though there is some evidence of a recent decline in productivity growth for the crops subsector, there is no such evidence in the livestock subsector.  相似文献

This paper present the results of recent empirical work on the short-run producetion flexibility of cow-calf producers in Western Canada. Several aspects of firm behaviour may be inferred from the econometric estimates, including short-run elasticities of supply and factor demand, and the total elasticity of cattle supply. The principal empirical findings are that many of the shourt-run supply and factor demand responses of firms, are elastic with respect to within-season price variability. The evidence does not support a vertical or negatively-sloped short-run supply curve for cattle, where one previously has been hypothesized in the theoretical literature.  相似文献

In this paper the optimal management strategy for intensive aquaculture is viewed in terms of a combined strategy of releasing the optimal number of recruits and harvesting those recruits at the optimal harvesting time. A model which can be used to determine the optimal management strategy is developed. In the model the optimal harvesting model documented by Bjorndahl (1988, 1990) in which harvesting and feed costs are considered, is extended by including release costs and how they influence the optimal number of recruits. The model forms the basis for an empirical analysis in which the optimal management strategy for a yearclass of Atlantic salmon farmed in Australia during 1989-91 is considered.  相似文献

This is an aggregative study covering the years 1946 to 1962, with the primary objective of examining the most significant factors which affect a market structure for farm labor. A recursive system is used to derive an equilibrium level of both hired and family farm labor during the period studied as well as an equilibrium level of future farm labor requirement by 1970 .
The findings show that the demand for farm labor was apparently not, or weakly, responsive to the farm wage rate in all regions and it was weakly responsive to the parity ratio, farm machinery and productivity. On the supply side, farm labor also was not, or weakly, responsive to the variables included in all regions with the exception of the farm wage rate or parity ratio in B.C. and the adjusted non-farm wage rate and farm machinery in the Atlantic region. The results also show that, in Canada as a whole, the projected family labor employment will be 294,000 manequivalents by 1910 or 42 percent decline as compared to the 1962 level, while the projected hired labor employment will be 114,000 manequivalents in 1970 or 14 percent increase in the eight years after 1962. This would likely be the tendency because of the continuous economic development on the one hand and the consolidation of farms on the other .  相似文献

Aquaculture satisfies a growing global demand for fish but also consumes an increasing share of the world’s wild fish resources. This has led to a concern that increased aquaculture production poses a threat to the sustainability of capture fisheries. We use a shrinkage estimator to estimate fishmeal demand from countries with different make‐up of meat and farmed salmon production. Although we are not able to identify structural differences between these sectors, the empirical results show that fishmeal demand is price inelastic. Technological change, however, is reducing fishmeal usage in feeds, suggesting that strong demand pressure on pelagic fish resources targeted for fishmeal is a temporary phenomenon.  相似文献

This study investigates the macroeconomic forces underlying forest clearcutting practices across Canada. In keeping with the relevant literature on environmental degradation, three forces are assumed to influence forest clearcutting: per capita gross domestic product (GDP), technology, and population density. While previous work has used models that assume linear relationships between the latter two variables and environmental degradation, this paper employs a more flexible (quadratic) model. Pooled regression analysis in the Atlantic, Quebec, Ontario, Prairie, and British Columbia regions between 1975-99 indicates that while technological change tends to have an inverted U-shaped relationship with forest area clearcut, population and GDP/capita tend to have the opposite effects. This last variable finding strongly rejects the Environmental Kuznets Curve hypothesis of an inverted U-shaped relationship between GDP/capita and forest area clearcut in Canada.  相似文献

This paper traces the development of consumer demand analysis at Agriculture Canada for the period 1972 to 1982 and identifies areas for future work. The objectives of this exercise are threefold: (I) to assess existing empirical results, emphasizing problems in specifying, estimating and evaluating alternative models; (2) to make the benefit of the Canadian experience available to applied researchers in Canada and other countries who are investigating the structure of consumer demand; and (3) to provide perspective for future analyses of consumer demand.

The U.S. NAFTA partners are important markets for U.S. meat exports. A source-differentiated almost ideal demand system is used in this study to estimate meat demand in Canada and Mexico. Empirical results suggest that while a U.S. price increase in the Canadian market is expected to increase U.S. sales revenues; it would decrease sales revenues in the Mexican market. Furthermore, an increase in meat expenditures in Canada and Mexico is expected to increase the demand for U.S. meats, while the bovine spongiform encephalopathy outbreaks have had a negative effect on U.S. and Canadian beef market shares. Finally, a decomposition of the causes of changes in demand for U.S. meats over time is performed.  相似文献

This paper reveals that wheat exporters to China compete in an imperfectly competitive market. U.S. wheat exports face strong price competition from Argentina, Australia, Canada, and the European Community, but has a highly elastic demand in China. By adopting an aggressive promotion policy, the U.S. could reduce the market shares of Argentina and Canada. China would shift to wheat from Argentina, Australia, and Canada if U.S. wheat exports were interrupted because of high prices or non-price trade frictions. An expansion in China's wheat imports would accrue to wheat from Argentina and the U.S.  相似文献

A six-equation structural model of the retail and import level demand for orange juice in Canada is estimated. Relative prices of Brazilian and U.S. imports are found to he important determinants of the quantity imported to Canada, and the Canadian market share for the U. S. and Brazil. Retail demand for orange juice in Canada is estimated to he price inelastic. The import level demand for U. S. product is estimated to he price inelastic while the import level demand for Brazilian product is estimated to he highly elastic. The final form of the model is used to simulate competitive price situations in the Canadian market.
On a fail un modèle eslimatif en six équations de la demande d'imponation el de vente au détail pour le jus d'orange au Canada. On a trouvé que les prix relatifs des importations brésiliennes et américaines jouent un rôle déterminant dans la quantilé d'importations sur le marché canadien et dans les titres floltants canadiens pour les Etats Unis et le Brésil. On estime que la demande, au niveau des détaillanls, pour le jus d'orange au Canada représente un prix fixe. On estime que la demande d'importations en produils brésiliens est des plus élastiques. On emploie la forme finale du modèle pour simuler les prix concurrents sur le marché canadien.  相似文献

This paper explores the interplay between immigration, ethnic diversity, and food demand in Canada. Attention focuses on the consequences of an increasingly diverse population on demand for food. The notion of dietary acculturation is discussed in the context of a fragmenting market for foods in Canada. A research agenda is presented with the intent to stimulate research that addresses the role of ethnicity in shaping demand for food in Canada. As Canada becomes more ethnically diverse, the landscape of the Canadian food environment will evolve. Understanding the impact of such change on demand for foods in Canada will become increasingly important. Such understanding can help inform the supply side of the market in terms of retail and food service location decisions, as well as decisions related to the marketing mix. Dans le présent article nous analysons l’interaction entre l’immigration, la diversité ethnique et la demande alimentaire au Canada et examinons tout particulièrement les répercussions de l’accroissement de la diversité ethnique sur la demande alimentaire. Nous abordons la notion d’acculturation alimentaire dans un contexte de segmentation du marché alimentaire au Canada. Nous présentons un programme de recherche qui vise à stimuler la recherche sur le rôle de l’ethnicité dans la détermination de la demande alimentaire au Canada. Plus la population canadienne se diversifiera sur le plan ethnique, plus l’environnement alimentaire évoluera, d’où l’importance de bien déterminer les répercussions de cette diversification sur la demande alimentaire au Canada. La détermination de ces répercussions aidera les acteurs du côté de l’offre à prendre des décisions quant à l’emplacement des magasins d’alimentation et des établissements de restauration et à la logistique commerciale (marketing mix).  相似文献
