Última Product differentiation and quality approach in the French market for oysters and mussels. ArchiMer Charles, Erwan; Paquotte, Philippe. France is one of the world top producers of oysters and mussels by aquaculture with 140 000 tonnes of oysters, 60 000 tonnes of mussels and an ex-farm turnover accounting to 350 millions US$ in 1996. The French market is by far the largest one in Europe for oyster and is supplied entirely by domestic production, with very little external trade. On the contrary, the French market for mussel is a very competitive one, widely open to imports. Given the evolution of market conditions due to the development of supermarkets, to the competition of new value added products and to the modification of consumer's habits, the French oyster and mussel producers have started to implement various strategies of product differentiation and of quality approach.

Ano: 1998 URL: http://archimer.ifremer.fr/doc/1998/acte-2523.pdf Greenhouse Tomatoes Change the Dynamics of the North American Fresh Tomato Industry AgEcon Cook, Roberta L.; Calvin, Linda. The rapid growth of the North American greenhouse tomato industry has changed the longstanding dynamics of the fresh tomato industry. During the 1990s, Canada emerged as the largest North American producer of greenhouse tomatoes, a prominence it never attained in the fresh field tomato industry. The United States and Mexico have also become important greenhouse tomato producers, consistent with their long dominance in North American fresh field tomato production. Greenhouse tomatoes have changed the look of U.S. retail tomato sales, where they now account for 37 percent of the quantity sold of fresh tomatoes. While the primary U.S. fresh field tomato product, the mature green tomato, long dominated retail sales, its share has decreased significantly due to...

Ano: 2005 URL: http://purl.umn.edu/7244 OPTIMAL QUALITY ASSURANCE SYSTEMS FOR AGRICULTURAL OUTPUTS AgEcon Carriquiry, Miguel A.; Babcock, Bruce A.; Carbone, Roxana. New quality assurance systems (QASs) are being put in place to facilitate the flow of information about agricultural and food products. But what constitutes a proper mix of public and private efforts in setting up QASs is an unsettled question. A better understanding of private sector incentives for setting up such systems will help clarify what role the public sector might have in establishing standards. We contribute to this understanding by modeling the optimal degree of "stringency" or assurance in a processor's quality control system over procurement of agricultural output when there exists uncertainty about quality. Our model addresses two questions: (1) Should a buyer of agricultural outputs implement a QAS as a way to gain and provide information...

Ano: 2003 URL: http://purl.umn.edu/18450 Intra-Industry Trade in Horizontally and Vertically Differentiated Agri-Food Products between Hungary and the EU AgEcon Ferto, Imre; Hubbard, Lionel J.. Intra-industry trade in agri-food products between Hungary and the EU is shown to be low and dominated by vertically rather than horizontally differentiated products, suggesting higher economic adjustment costs. Following recent empirical studies, we then test econometrically for the determinants of this trade using different measures of horizontal and vertical trade, and employing an array of popular explanatory variables. Results suggest that separating the measure of intra-industry trade into vertical and horizontal provides for better estimation and supports the contention that the determinants may differ by type of trade. In the regression analysis, the level of intra-industry trade is found to serve as a better dependent variable than the degree or...

Ano: 2002 URL: http://purl.umn.edu/24884 Quality and Competition: An Empirical Analysis across Industries AgEcon Crespi, John M.; Marette, Stephan. This paper empirically explores the link between quality and concentration in a cross-section of manufactured goods. Using concentration data and product quality indicators, an ordered probit estimation explores the impact of concentration on quality that is defined as an index of quality characteristics. The results demonstrate that market concentration and quality are positively correlated across different industries. When industry concentration increases, the likelihood of the product being higher quality increases and the likelihood of observing a lower quality decreases.

Ano: 2006 URL: http://purl.umn.edu/18426 Common Labels and Market Mechanisms AgEcon Boizot-Szantai, Christine; Lecocq, Sebastien; Marette, Stephan. In this article, the impact of common labels is investigated with both theoretical and empirical approaches. Recent statistics regarding the egg market in France suggest that retailer brands largely adopt common labels. A simple theoretical framework enables us to determine the conditions under which producers and/or retailers with different product qualities decide to post a common label on their products. In particular, a situation of multiple equilibria (one where the label is used by the high-quality seller only and one where it is used by the low-quality seller only) is exhibited when the cost of the label is relatively large. The demand is then estimated for different segments of the French egg market, including producer/retailer brands with/without...

Ano: 2005 URL: http://purl.umn.edu/18588 Do Local Production, Organic Certification, Nutritional Claims, and Product Branding Pay in Consumer Food Choices? AgEcon Batte, Marvin T.; Hu, Wuyang; Woods, Timothy A.; Stan, Ernst. This research furthers the assessment of consumer demand for locally produced foods, while also considering a host of other food attributes that may interact to influence consumer utility. Using stated preference data from a choice-based conjoint analysis survey instrument, we estimate willingness-to-pay for processed food products (blackberry jam) that are differentiated with respect to their branding, the location of their production, certification as organically produced, branding as a product of a small family farming association, and carrying a State Proud certification. Although price is the most important single attribute influencing consumer choice for our sample, consumers also were willing to pay more for food products produced in their state or...

Ano: 2010 URL: http://purl.umn.edu/61026 TRACEABILITY IN THE U.S. FOOD SUPPLY: ECONOMIC THEORY AND INDUSTRY STUDIES AgEcon Golan, Elise H.; Krissoff, Barry; Kuchler, Fred; Calvin, Linda; Nelson, Kenneth E.; Price, Gregory K.. This investigation into the traceability baseline in the United States finds that private sector food firms have developed a substantial capacity to trace. Traceability systems are a tool to help firms manage the flow of inputs and products to improve efficiency, product differentiation, food safety, and product quality. Firms balance the private costs and benefits of traceability to determine the efficient level of traceability. In cases of market failure, where the private sector supply of traceability is not socially optimal, the private sector has developed a number of mechanisms to correct the problem, including contracting, third-party safety/quality audits, and industry-maintained standards. The best-targeted government policies for strengthening...

Ano: 2004 URL: http://purl.umn.edu/33939 Labeling Regulations and Segregation of First- and Second-Generation Genetically Modified Products: Innovation Incentives and Welfare Effects AgEcon Moschini, GianCarlo; Lapan, Harvey E.. We review some of the most significant issues and results on the economic effects of genetically modified (GM) product innovation, with emphasis on the question of GM labeling and the need for costly segregation and identity preservation activities. The analysis is organized around an explicit model that can accommodate the features of both first-generation and second-generation GM products. The model accounts for the proprietary nature of GM innovations and for the critical role of consumer preferences vis-a-vis GM products, as well as for the impacts of segregation and identity preservation and the effects of a mandatory GM labeling regulation. We also investigate briefly a novel question in this setting, the choice of 'research direction' when both...

Ano: 2005 URL: http://purl.umn.edu/18535 Substitution between domestic and imported orange juice and impacts of U.S. tariffs on prices and production AgEcon Brown, Mark G.; Spreen, Thomas H.; Lee, Jonq-Ying. A demand system model differentiating goods by product form and origin is developed to examine the impact of eliminating U.S. tariffs on orange-juice prices. An empirical analysis suggests a range of tariff impacts on prices depending on the degree of substitution between products. The model yielded similar results as alternative models when substitution was assumed to be relatively strong. In the long run, lower, without-tariff prices can be expected to lead to lower Florida orange planting and production levels. A sustained reduction in the U.S. OJ price of half the value of the FCOJ tariff is estimated to reduce orange planting levels by about 50% and orange production would declined by 24% by 2021-22.

Ano: 2001 URL: http://purl.umn.edu/52888 Input Quality in the Sugar Beet Industry AgEcon Boland, Michael A.; Marsh, Thomas L.. Using 23 years of data (1978-2000), this study examines seven vertically integrated sugar beet plants representing three different companies in the United States. The objective of this research is to identify the marginal costs of producing sugar beets for vertically integrated sugar beet processors as a way of determining the cost savings from higher quality sugar beets. In doing so, we account for quality differences in the sugar beet input that are used to manufacture the refined sugar output. The results quantify links between high quality sugar beets and lower processing costs.

Ano: 2006 URL: http://purl.umn.edu/7316 HOW DIFFERENTIATED IS THE SCOTTISH BEEF? AN ANALYSIS OF SUPERMARKET DATA PANEL AgEcon Revoredo-Giha, Cesar; Lamprinopoulou-Kranis, Chrysa; Leat, Philip M.K.; Kupiec-Teahan, Beata; Toma, Luiza; Cacciolatti, Luca. The Scottish red meat industry is a major part of the Scottish agricultural economy and is known for producing high quality beef and lamb. Beef and lamb which are produced and processed in Scotland and according to a quality assured production specification, carry the EU ‘Protected Geographical Indications’ (PGI) name of ‘Scotch’. In addition, red meat in Scotland has to compete with high quality imported products (e.g., from Brazil or Argentina) or with meat from elsewhere in the United Kingdom. This paper focuses on the situation of Scotch beef and how differentiated it is in the eyes of consumers. For this purpose we use two years’ retailing data for Scotland (and by socio-economic group) from a major supermarket to estimate the conditional demand for...

Ano: 2009 URL: http://purl.umn.edu/109392 Measuring Market Power in the Ready-To-Eat Cereal Industry AgEcon Nevo, Aviv. The ready-to-eat cereal industry is characterized by high concentration, high price-cost margins, large advertising to sales ratios, and numerous introductions of new products. Previous researchers have concluded that the ready-to-eat cereal industry is a classic example of an industry with nearly collusive pricing behavior and intense non-price competition. This paper empirically examines this conclusion. In particular, I estimate price-cost margins, but more importantly I am able empirically to separate these margins into three parts: (1) that which is due to product differentiation; (2) that which is due to multi-product firm pricing; and (3) that due to potential price collusion. The results suggest that given the demand for different brands of cereal,...

Ano: 1998 URL: http://purl.umn.edu/25164 EMERGING FORMS OF COMPETITIVE ADVANTAGE: IMPLICATIONS FOR AGRICULTURAL PRODUCERS AgEcon Barone, Michael J.; Decarlo, Thomas E.. Traditional recommendations for building sustainable competitive advantages revolve around differentiating a product from the competition along attributes that are important and relevant to customers. However, strategic approaches based on such notions do not represent viable options for companies competing in commodity markets characterized by a lack of physical product differentiation. The objective of this paper is to conduct a literature review with the aim of identifying alternative approaches to creating competitive advantage that can be used even under conditions in which no differences in actual quality exist across products. This review of the literature uncovered three non-traditional strategies that provide a basis for perceptually...

Ano: 2003 URL: http://purl.umn.edu/18690 Welfare Measurement and Quality Product Differentiation in Agriculture: An Example From the EU15 Beef Sector AgEcon Ramos, Maria Priscila; Drogue, Sophie; Marette, Stephan. This paper examines the impact of two different model specifications on welfare estimations. A model specification that takes into account product differentiation is compared to a specification where the product differentiation is overlooked. The welfare comparison under both specifications show some biases of aggregation as well as ambiguous results: the welfare under one specification may be larger or lower than the welfare under the alternative assumption. In order to illustrate our theoretical conclusions, we present an application to the EU15 beef market. We show that the welfare when the product differentiation is taken into account is smaller than the welfare when the product differentiation is omitted.

Ano: 2005 URL: http://purl.umn.edu/24720 Environmental Labeling and Technology Adoption in the Presence of Strategic Interactions AgEcon Konishi, Yoshifumi. This manuscript analyzes the effect of binary ecolabeling on the strategic competition of Cournot duopolists in environmental technology and the output market. Under binary labeling, firms' abatement technologies are not directly observable by consumers but are certified if they satisfy preset ecological standards. Given this asymmetry, I set up the regulator's problem as one of choosing a technology standard, or "cutoff," in emissions per unit of output, below which all abatement efficiency levels are certified. The regulatory authority faces a trade-off in choosing the socially optimal cutoff: The regulator would like to raise the standard to reduce emissions but needs to lower it in order to induce technology adoption. There are three important...

El objetivo de la presente investigación es cuantificar el impacto del índice de productividad CONEAT sobre los precios pagados por los inmuebles rurales en el Uruguay. El índice CONEAT intenta expresar la relación entre la capacidad de producción de un predio, medida en términos de carne y lana, y las unidades de suelo que lo componen. La ventaja de su uso radica en su fácil comprensión por parte de los agentes. La principal crítica es que utiliza exclusivamente parámetros de producción ganadera que hacen cuestionable su uso cuando se comparan inmuebles con otras aptitudes productivas. Sin embargo, aun se lo utiliza frecuentemente para tasar inmuebles rurales o comparar productividad entre inmuebles. Para estimar el valor monetario implícito que los...

Ano: 2011 URL: http://purl.umn.edu/121684 Allowing for Group Effects When Estimating Import Demand for Source and Product Differentiated Goods AgEcon Muhammad, Andrew. In this study an import demand model (differential production model) is presented that is used in estimating the demand for source and product differentiated goods simultaneously. Unlike the traditional import demand models, this model can account for changes in relative group expenditures. Expenditure estimates differed when comparing the differential production model and Rotterdam model results. Results showed that if group revenue shares are relatively fixed, then the bias in expenditure estimates due to omitting group effects will be small when using traditional demand models such as the AIDS or Rotterdam models. As relative group shares significantly change and diverge the bias increases, particularly for imports representing a larger share of group...

Ano: 2008 URL: http://purl.umn.edu/6364 DETERMINING BILATERAL TRADE PATTERNS USING A DYNAMIC GRAVITY EQUATION AgEcon Kim, MinKyoung; Cho, Guedae; Koo, Won W.. Using a dynamic gravity equation, we show that the national product differentiation model explains food and agricultural trade more properly, while the product differentiation model is more appropriate to explain large-scale manufacturing trade. In this context, our result is not consistent with the one found by Head and Ries (2001) in the short-run. The intuitive explanation for this result is that inward foreign direct investment can occur through either merger or acquisition in the short-run. Second, the pattern of bilateral trade could quickly adjust to changes in relative income between countries. Furthermore, we illustrate the positive impacts of world income growth on bilateral trade, which is in sharp contrast with the conventional analysis....

Ano: 2003 URL: http://purl.umn.edu/23538 Should Europe Further Strengthen Intellectual Property for Plant Breeders? An Analysis of Seed Industry Proposals AgEcon Eaton, Derek J.F.; van Tongeren, Frank W.. This paper illustrates the potential negative effects of increasing the scope of plant breeders' rights (PBR) protection, as has been proposed for Europe by leading plant breeding firms. Such a policy could increase the costs for varietal development for breeding companies, particularly if their access to varieties of the market leader is constrained. This is represented as an asymmetrical increase in breeders' cost functions in a simple model of endogenous quality choice under price competition. Increased scope of IPR protection leads to increased profits for the leading breeding company but decreases in varietal quality and both farm and overall profits.
