  Citation × Citation Citation Abstract Copy Title: The Effect on Product Differentiation by Origin Labeling of Seafood Author: Miyata, Tsutom Problems with the security of imported foods and with false indications of origin have recently been uncovered in Japan, leading to increased consumer interest in the country or place of origin of foods. The place of origin is an important element when a consumer buys sea food. This report presents a case study of sea urchin purchase in Japan to test the above situation. It focuses on the competitiveness of Japanese marine products of local marine products and brands, because the former is affected by the latter. Before 2002, Japan had been increasing its imports of sea urchins in the face of declining domestic yield. Since then, the import volume has declined, although domestic production remains low. Yet demand for product from Iwate prefecture, Japan’s second largest producer, hasn’t changed. To find out why, we interviewed processors in and around Iwate; had a questionnaire for residents in the prefectural capital, Morioka; analyzed statistics from Morioka’s central wholesale market; and spoke to the market’s auctioneer. The results show that consumers have a lot of attention to product safety, and local people highly assess the value of local product. We presume that a trusted label of origin promotes both brand recognition and a perception of product safety.

  Citation × Citation Citation Abstract Copy Title: Generalization of Age-Structured Models in Theory and Practice Author: Steinshamn, Stein Ivar A generalization of the harvesting functions and the stock updating functions in age-structured bioeconomic models is outlined. Using this generalization everything from completely uniformly distributed fish to extreme schooling is taken care of. The classical Beverton-Holt model comes out as a special case of the generalized model. Both the theoretical outline as well as practical numerical examples are provided, and the generalization can be applied both for simulation as well as optimization purposes given appropriate software. Here we apply advanced non-linear programming to maximize the net present value in a bioeconomic setting where the new updating and harvesting functions are used as constraints. This is possible thanks to new software, such as KNITRO, for solving highly nonlinear problems. Applications of this generalized model produce interesting new results. One such practical result is that pulse fishing seems to become less and less economically profitable as we move from uniformly distributed fish to schooling species. The main reason why pulse fishing cease to be optimal in schooling fisheries, is that the economies of scale present in search fisheries gradually disappear when we move from search fisheries to schooling fisheries. This may have important implications for how fish stocks ought to be managed in the future, especially with respect to total allowable catches based on bioeconomic criteria.

  Citation × Citation Citation Abstract Copy Title: An Examination of the Shrimp Futures Market Author: Martínez-Garmendia, Josué, Anderson, James L. Year: 2001 The only two seafood commodities traded in futures markets are frozen white and black tiger shrimps on the Minneapolis Grain Exchange (MGE). These two contracts, however, have failed to attract the expected trade volume based on the underlying shrimp cash market flow. First, we investigate the hedging effectiveness of these contracts. Then we also try to determine the adequacy of the premiums/discounts for non-par deliveries associated with the various shrimp size categories traded in each contract. Finally, we attempt to determine whether these contracts are unbiased predictors of cash market prices. The analyses indicate that the hedging effectiveness of both contracts is relatively modest. It is concluded that part of the explanation for the performance of the contracts resides in high deliverable category exchange option values, which stem from volatility in the price differentials between size categories. Results indicate ineffective premiums/discounts and poor predic tive ability of both contracts.

  Citation × Citation Citation Abstract Copy Title: Cultural and Natural Assets for Willamette Basin, Oregon Sustainability Author: Gilden, Jennifer S., Smith, Courtland L. Year: 2001 In this paper, we consider the transfer of environmental and cultural assets to the next generation as a potential measure of sustainability. We define net assets as the value of renewable and nonrenewable natural resources plus humanmade, intellectual, social, and cultural capital, minus any debts. We apply this approach by first reviewing survey data reflecting how cultural capital may yield microbehaviors that add up to the macroresults of environmental protection and restoration. Second, we evaluate how human activities play out on the landscape. Rather than a dollar measure of assets, historical changes in land use are a proxy for asset change. A broad look at the Willamette Valley, Oregon s most urban and industrial area, shows that capital in forest lands has shifted from significant loss to improvement, agricultural lands have decreased only slightly, and urban development has taken a relatively small share of the total landscape. However, sprawl is increasing despite efforts to contain urban growth. Looking at highly valuable ecological features for the future, we find that wetlands continue to be lost, important species are endangered, and the secondary impact of urbanization on the landscape is increasing.

  Citation × Citation Citation Abstract Copy Title: ITSQ in Chilean Fisheries: The Case of the Squat Lobster (Pleuroncodes monodon) Author: Cerda-Amico, Rene J., Urbina-Veliz, Mauro Year: 2001 Among other mechanisms, the Chilean fishing act established a system of extraordinary fishing permits (EFP) to access the fisheries in stage of recovery or incipient stage of development. The EFP entitles its holder the right to catch during 10 years a fraction of the global annual quota. The right is obtained through auction where one tenth of the global quota is offered annually. Auction results show concentration of the ITSQ for squat lobster in few firms and there is also evidence of cooperation among them within this market. Although the fleet capacity is somewhat less than in previous periods under free access, the fishing season is now longer; fishing firms look for maximizing the value of the catch by distributing the fishing effort throughout the season to obtain the highest fishing yields. The fishery resource has kept high level of biomass since the ITSQ were introduced, but it is not possible to assert that there is a correlation between the two.

  Citation × Citation Citation Abstract Copy Title: The Future of Capitalism Revisited Author: Farrell, John P. Year: 2001 This essay deliberates on the future of capitalism or, more specifically, the mixture of command and market likely to characterize the modern economy two to three decades on. I start by discussing global trends in the supply and demand for market and non-market goods and the collateral demand for institutions, arguing that the value of non-market goods can be expected to rise relative to market goods, because of the relative fixity of supply of some nonmarket goods (esthetic environmental goods, e.g.), limited substitution possibilities and the high cost of achieving appropriate institutional change. Growing tension between, on the one hand, the demand for non-market goods and the ability of the economy to produce such goods will drive change in the nature of capitalism. If institutions are unable to deliver, if the U.S. economy proves rigid, lacking in ability to adapt, then we can expect bureaucratic resolutions costly in terms of forgone growth. If, however, institutions can adapt in market-friendly way, we can expect continued growth and more efficient production of both market and non-market goods.
