A Framework for Analyzing Technical Trade Barriers in Agricultural Markets AgEcon
Roberts, Donna; Josling, Timothy E.; Orden, David.
Technical trade barriers are increasingly important in the international trade of agricultural products. Designing technical trade measures that can satisfy the growing demand for food safety, product differentiation, environmental amenities, and product information at the lowest cost to the consumer and to the international trading system requires an understanding of the complex economics of regulatory import barriers. This report proposes a definition and classification scheme to frame discussion and evaluation of such measures. Open-economy models that complement the classification scheme are developed graphically to highlight the basic elements that affect the economic impacts of changes in technical trade barriers.

A "G" chromosome banding study of three cupped oyster species : Crassostrea gigas, Crassostrea angulata and Crassostrea virginica (Mollusca : Bivalvia) ArchiMer
Leitao, Alexandra; Thiriot-quievreux, Catherine; Malheiro, Isabel; Boudry, Pierre.
The G-banding technique was performed on chromosomes from gill tissue of three cupped oyster species : Crassostrea gigas, Crassostrea angulata and Crassostrea virginica. Identification of the ten individual chromosome pairs was obtained. Comparative analysis of G-banded karyotypes of the three species showed that their banding patterns generally resembled each other, with chromosome pair 3 being similar in all three species. However, differences from one species to another were also observed. The G-banding pattern highlighted greater similarities between C. gigas and C. angulata than between these two species and C. virginica, thus providing an additional argument for genetic divergence between, these two evolutionary lineages. C. gigas and C. angulata...

A GAME THEORETIC ANALYSIS OF TURKISH ACCESSION TO A EUROPEAN CUSTOMS UNION AgEcon
Kennedy, P. Lynn; Atici, Cemal.
The entrance of additional countries into a European customs union, in this case Turkey, and its impact on agriculture are examined. Results from a trade simulation model are used as components of a Political Preference Function and utilized within a game theoretic framework to identify the optimal strategies for Turkey, the EU, and the U.S. Turkey's best interest, from an agricultural perspective, involves adoption of agreements made in the Uruguay round of GATT as a developing country rather than applying EU protection. Although free trade is not the optimal solution, simulations indicate that the solution does involve the reduction of agricultural protection levels.

A Game Theoretic Approach to Organic Foods: An Analysis of Asymmetric Information and Policy AgEcon
McCluskey, Jill J..
Demand for healthy, safe, and environmentally friendly food products has been increasing. In response, producers are marketing organic and other quality-differentiated foods, sometimes claiming to have followed sound environmental and animal welfare practices. These products frequently have unobservable quality attributes. If the profitmaximizing producer is able to deceive the consumer with a false claim, then he or she will enjoy a higher price with lower production costs (compared to the full disclosure outcome). The analysis described in this paper shows that repeat-purchase relationships and third-party monitoring are required for high-quality credence goods to be available. Policy implications of this analysis for national organic food standards are...

A General Conceptual Approach to Modeling the Livestock Sector: Application to the Japanese Swine-Pork Sector Model with Analysis of the "No Gate Price Policy Scenario" AgEcon
Fabiosa, Jacinto F..
This study develops a generic conceptual approach to modeling the livestock sector that provides better coverage of variables to ensure the consistency in the underlying biologics of the model and also provides consistent rules of specification. This approach is applied to modeling the swine-pork sector of Japan and then used to analyze the impact of removing Japan's gate price policy and variable levy for pork imports. The new approach departs significantly from existing models. For consistency in the biologics of the model both live animals and meat components of the sector are fully covered. The structure clearly differentiates stock and flow variables and investment and production decisions. A standard rule of specification is established that only...

A GENERALIZED DISTANCE FUNCTION AND THE ANALYSIS OF PRODUCTION EFFICIENCY AgEcon
Chavas, Jean-Paul; Cox, Thomas L..
A generalization of Shephard's distance functions is proposed, extending the usefulness of distance functions in economic analysis. Applications to efficiency measurements and productivity analysis are presented. New indexes of productivity, and technical, allocative and scale efficiency are proposed and analyzed. Interpretation of these indexes in terms of ray-average cost, ray-average revenue, and cost-to-revenue ratio is discussed.

A genetic comparison of Atlantic and Mediterranean populations of a saltmarsh beetle OMA
Desender, K.; Serrano, J..
Enzyme and dispersal polymorphism in the saltmarsh carabid beetle <i>Pogonus chalceus</i> Marsham were compared between 30 Atlantic and nine Mediterranean European populations. Allozyme results showed that Mediterranean beetles (France, Spain) are genetically distinct from Atlantic populations. All Mediterranean beetles screened showed complete fixation at one locus (IDH1), which in Atlantic populations nearly always varied, whereas some unique Mediterranean alleles were observed for another locus (MPI). Genetic differentiation (allozymes) between Mediterranean populations, although highly significant, appeared to be much lower (F<sub>st</sub> = 0.098) than between Atlantic populations (F<sub>st</sub> = 0.178). Beetles...

A GROUP INCENTIVE CONTRACT TO PROMOTE ADOPTION OF BEST MANAGEMENT PRACTICES AgEcon
DeVuyst, Eric A.; Ipe, Viju C..
The control of agricultural nonpoint source pollution is emerging as a priority of state and national pollution control programs. Best management practices (BMPs) are often proposed as a method of control. Many BMPs are perceived by farmers as having economic disadvantages when compared to conventional management systems. In the absence of tougher environmental restrictions on farmer behavior and complete observability of individual farmer actions, it may be necessary to provide economic incentives to encourage farmer adoption of BMPs within environmentally sensitive watersheds. This study investigates the use of a group incentive contract to encourage adoption of BMPs. The idea behind the group incentive contract is to compensate farmers for actual...

A GROUP INCENTIVE PROGRAM FOR FARMER ADOPTION OF BEST MANAGEMENT PRACTICES: AN APPLICATION TO THE NITRATE POLLUTION PROBLEM IN CENTRAL ILLINOIS AgEcon
Ipe, Viju C.; DeVuyst, Eric A..
The paper demonstrates a group incentive program to encourage farmer adoption of best management practices. It is demonstrated that the best management practices may not actually reduce farm profits but may increase farm profits and reduce environmental pollution. This may bring about a win-win situation for sponsor, the farmer participating in the program, and the society as a whole. The results show that the farmers subjective beliefs about response of corn yields and profits to nitrogen application differ from the simulated responses which in turn results in the willingness-to-Accept for adoption best management practices significantly higher than the expected program payments. The program could be implemented as an educational effort to...

A LINEAR APPROXIMATE ACREAGE ALLOCATION MODEL AgEcon
Holt, Matthew T..
It is shown that the first-order differential acreage allocation model developed by Bettendorf an Bloome and by Barten and Vanloot, and based on certainty equivalent profit maximization, may be extended to a levels version. The levels model, referred to as a linear approximate acreage allocation model, is potentially useful when panel or cross-sectional data are employed. An empirical application with U.S. state-level corn flex acreage data for the period 1991-95 indicates the feasibility of the approach. Estimated price and scale elasticities are generally larger than previous estimates, and are perhaps indicative of acreage response under the provisions of the 1996 Farm Act.
