Última ADDITIONALITY OF CREDIT GUARANTEES FOR U.S. WHEAT EXPORTS AgEcon Diersen, Matthew A.; Wilson, William W.; Dahl, Bruce L.; Satyanarayana, Vidyashankara. The value of credit guarantee programs has recently been called into question. Credit guarantees are important marketing tools in the world wheat market, both to develop new markets and to compete in existing markets. This study examines the additionality of export credit guarantees. Empirical demand models were developed and estimated using pooled data among importing countries. Models were estimated for each of the principal exporting countries providing export credit guarantees: the United States, Canada and France. Additionality of credit guarantees were also contrasted to the Export Enhancement Program. Positive additionality was found for CCC guarantees, indicating that the GSM programs have resulted in additional exports that would not have...

Ano: 1997 URL: http://purl.umn.edu/23240 BIDDING ON RAILCARS FOR GRAIN: A STRATEGIC ANALYSIS AgEcon Wilson, William W.; Dahl, Bruce L.. Many of the U.S. railroads have introduced highly differentiated services for grain shipments in recent years, generally in the area of forward guaranteed car service. Taken together with other alternatives, these mechanisms have had the effect of establishing priority allocations among shippers. In most cases, pricing and allocation of these services has been with some type of bidding mechanisms. This paper explores the economic implications of these mechanisms on the grain shipping industry. A model was developed to identify factors affecting the value of these services and was analyzed in the context of a typical midwestern grain shipment. A game theory model of competitive bidding was also developed to analyze the effects of critical strategic...

Ano: 1997 URL: http://purl.umn.edu/23168 Bulk Fuel Distribution Costs For Cooperatives in North Dakota AgEcon Dahl, Bruce L.; Cobia, David W.; Dooley, Frank J.. Economic-engineering cost data and a simulation model were used to analyze the impact of sales density, size of sales area, sales volume, and equipment configuration on costs of bulk fuel delivery by cooperatives. Fixed costs accounted for the majority of delivery costs regardless of sales density or size of sales area, at least for the relevant range of these variables for North Dakota. Increasing the radius of a sales area from 5 to 50 miles increased average costs only $.02 to $.09/gal. Doubling sales by either doubling the size of the sales area or the sales density reduced average total costs by nearly 50%. Thus, cooperatives with excess delivery capacity could achieve significant savings if they consolidate to operate closer to the capacity of...

Ano: 1995 URL: http://purl.umn.edu/23435 CONSISTENCY OF QUALITY CHARACTERISTICS IN HARD RED SPRING WHEATS AgEcon Dahl, Bruce L.; Wilson, William W.. Greater sophistication of buyers in the wheat market has increased demands for higher quality wheats and focused attention on the consistency of the quality of wheat purchased. In this study, the variability of wheat quality characteristics was examined at different stages of the marketing chain. Variability was measured by variety and at farm and export levels. Comparisons were made with Canada where similar data were available. Different measures of variability were utilized where data were available. Inter-year variability, intra-year variability, and within-lot variability of wheat quality characteristics were measured at different points in the wheat marketing chain in the United States and Canada. Variability of many characteristics was...

Ano: 1998 URL: http://purl.umn.edu/23305 Contracting for Canola in the Great Plains States AgEcon Wilson, William W.; Dahl, Bruce L.. Canola has become an important crop in the last decade in the U.S. Production of canola is risky and competes with other crops which have a range of risk reduction mechanisms. Alternative contracting strategies were evaluated by comparing returns to labor and management for growers and gross margins for processors. Alternative contracting strategies included no contract, fixed price with and without act of god provisions, and an oil premium contract. Grower returns and processor gross margins were simulated and resulting distributions were evaluated using stochastic efficiency with respect to a function. We estimated certainty equivalents and ranked contract preferences for both growers and processors by region in North Dakota. Grower and processor risk...

Ano: 2010 URL: http://purl.umn.edu/95751 CONTRACTING STRATEGIES FOR EU TRACEABILITY REQUIREMENTS AgEcon Wilson, William W.; Dahl, Bruce L.. A principal-agent problem was specified to define the equilibrium solution of a contracting strategy for a U.S. supplier exporting wheat to meet EU traceability requirements. The buyer (principal) offers a contract, the supplier (agent) accepts the contract, and then the supplier decides whether to offer a contract to the farmer. Nature at each level of the supply chain represents uncertainty due to adventitious commingling and imperfect information. Results indicate farmers would require 9 c/bu and suppliers 8 c/bu to induce their participation in the contracting strategy.

Ano: 2006 URL: http://purl.umn.edu/23535 COSTS AND RISKS OF CONFORMING TO EU TRACEABILITY REQUIREMENTS: THE CASE OF HARD RED SPRING WHEAT AgEcon Wilson, William W.; Henry, Xavier; Dahl, Bruce L.. Stochastic simulation was used to determine the marginal cost and optimal testing strategy (location and intensity) for an integrator conforming to proposed European Union traceability requirements for imported hard red spring wheat. Cost, risks and premiums were determined for exports of non-genetically modified (non-GM) wheat from the U.S. to the EU. Cost components include certified seed, certification and auditing, testing, traceability, quality loss, and a risk premium for the added risk of a dual traceability system over a single non-traceability system. The optimal strategy is the one that maximizes the integrator's utility (minimizes disutility of integrator's additional costs). Adventitious commingling is defined stochastically. Results...

Ano: 2005 URL: http://purl.umn.edu/23484 COSTS AND RISKS OF TESTING AND SEGREGATING GM WHEAT AgEcon Wilson, William W.; Dahl, Bruce L.. Development of genetically modified crops is challenging the functions of the grain marketing system with many participants arguing for Identity Preservation systems prior to release of GM varieties. In this study, a stochastic optimization model was developed to determine optimal testing strategies. The model chooses the optimal testing strategy that maximizes utility (minimizes disutility) of additional system costs due to testing and rejection and allows estimation of the risk premium required for sellers to undertake a dual marketing system with GM/Non-GM segregations over the current Non-GM system. Elements of costs (testing costs, rejection costs, and risk premium) were estimated for a base model representing a grain export chain. The model...

Ano: 1995 URL: http://purl.umn.edu/23331 Distribution Costs for Dry Fertilizer Cooperatives AgEcon Dahl, Bruce L.; Cobia, David W.; Dooley, Frank J.. Economic-engineering cost data and a simulation model was used to analyze the impact of sales area size and volume and equipment configuration on costs of custom application of bulk fertilizer by cooperatives. Fixed costs accounted for most of the custom application costs regardless of sales density or size of sales area for the relevant range of these variables in North Dakota. Increasing the radius of a sales area from 5 miles to 50 miles increased average costs by $2.79/ton to $32.26 per ton in Eastern North Dakota. Doubling sales by either doubling the size of the sales area or the sales density reduced average total costs by over a third for the smallest plant (500-ton storage) and over 40% for a 2,000-ton plant. Therefore, substantial savings,... Tipo: Working or Discussion Paper Palavras-chave: Agribusiness. Ano: 1995 URL: http://purl.umn.edu/23117 Dynamic Changes in Market Structure and Competition in the Corn and Soybean Seed Sector AgEcon Wilson, William W.; Dahl, Bruce L.. The purpose of this paper is to analyze the dynamics of R&D investments, and the structure of the seed distribution sector using novel data sets that have not been used before to describe competition in these industries. The results describe four sets of issues of particular importance. One is that while all agbiotechology firms have increased their R&D expenditures, there have been sharp differences in the scope of this spending. Most important is that this has spawned the growth in what is now referred as “seeds and traits.” Second, a large number of future traits will be commercialized in the coming years. A third set of results indicates that one firm grew its market share by 14% and a portion of this growth has been through acquisition. The...

Ano: 2010 URL: http://purl.umn.edu/58487 EFFECT OF HARD RED SPRING WHEAT CONSISTENCY ON MILLING VALUE AgEcon Dahl, Bruce L.; Wilson, William W.. Increased concerns over the quality of wheat in domestic and export markets has focused attention on the consistency of wheat quality. This study utilized three measures to examine the effect of variability in characteristics on the milling value of wheat. Distributions and correlations for wheat quality characteristics were estimated from U.S. wheat export data from 1985-1997. Effects of variability of wheat characteristics on the value of wheat to the miller for each of the three measures were estimated using a simulation model. U.S. No. 1 exports of Hard Red Spring (HRS) had higher value to millers on each of the three measures (net wheat, millable wheat index, and value added in milling) than did exports of No. 2 or better (OB). However, the value... Tipo: Working or Discussion Paper Palavras-chave: Quality consistency; Wheat; Net wheat; Millable wheat value index; Milling value; HRS; HRW; Marketing. Ano: 1999 URL: http://purl.umn.edu/23378 EVALUATION OF CHANGES IN GRADE SPECIFICATIONS FOR DOCKAGE IN WHEAT AgEcon Wilson, William W.; Dahl, Bruce L.. Dockage levels in U.S. wheat exports have been a continuing concern. Recent proposals have focused on changes in U.S. grain standards that would include dockage limits. In this report, dockage trends and practices were documented and effects of prospective changes evaluated. Results indicate the marketing system is currently working effectively with costs of extra cleaning being borne partly by buyers, elevators, and to some extent farmers. Suggested mandates would increase cleaning and result in increased costs (ultimately discounts to growers) and potentially in shifts in grades purchased. Proposed changes in grain standards are also a departure from the generally followed approach to regulation in the United States. In this case, a regulation is...

Ano: 2001 URL: http://purl.umn.edu/23624 FACTORS AFFECTING THE SUPPLY OF QUALITY SPRING WHEATS: COMPARISONS BETWEEN THE UNITED STATES AND CANADA AgEcon Dahl, Bruce L.; Wilson, William W.. The demand for high quality hard wheats has been increasing. In this paper, factors affecting the supply and consistency of high quality wheats in Canada and North Dakota were compared and contrasted. Differences exist in the development and release of new varieties which affect the number and quality of hard wheats produced. Variety numbers and concentration were examined with a range of measures. Wheat area in Canada was found to be concentrated in fewer varieties than in North Dakota. These results were more apparent for durum than for hard red spring wheats. However, there was a trend toward more concentration in North Dakota and less in Canada. Protein, yield, and trade-offs were compared. Alberta appears to have a comparative advantage in the...

Ano: 1997 URL: http://purl.umn.edu/23472 FORWARD SHIPPING OPTIONS FOR GRAIN BY RAIL: A STRATEGIC RISK ANALYSIS AgEcon Wilson, William W.; Priewe, Steven R.; Dahl, Bruce L.. In the late 1980s, grain-hauling railroads began offering alternatives that have made shipping decisions more strategic. Shippers now confront alternatives ranging from nearby and unguaranteed ordering to various durations of forward and guaranteed shipment. Each has varying penalties for cancellation and payments from the railroad for nonperformance, and differing risks and payoffs. Because of the configuration of choices, shippers confront a portfolio of shipping alternatives. A dynamic stochastic simulation model was developed to analyze alternative strategies. The model includes the effects of uncertainties in tariff rate changes, car premiums, basis levels, forward and spot grain purchases, and receiving railcars under each of three alternatives....
