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...

LOGISTICAL STRATEGIES AND RISKS IN CANADIAN GRAIN MARKETING AgEcon
Wilson, William W.; Dahl, Bruce L.; Carlson, Donald C.E..
Supply chain management in grain marketing has become very important with the maturity of the industry. This is particularly important in the Canadian grain marketing system which has experienced disruptions for various reasons over many years. These problems have been the topic of numerous industry evaluations, have resulted in a complaint about service obligations and recently have been addressed by the Estey Commission. A detailed model of the supply chain in the Canadian grain logistics system was developed in this paper to evaluate factors that cause disruptions, as well as the effect of several important logistics and marketing strategies on system performance. The results indicated that in a normal year there is sufficient randomness throughout...

IMPORT TENDERS AND BIDDING STRATEGIES IN WHEAT AgEcon
Wilson, William W.; Dahl, Bruce L..
Bidding competition plays an important role in price discovery and the determination of suppliers in international grains. In this paper we analyze international bidding competition for wheat for a specific importer. Tender data over the period 1993-1999 were analyzed and bid functions estimated by class of wheat (hard red spring, hard amber durum, and hard red winter denoted as HRS, HAD, and HRW, respectively) and by selling firm. A stochastic simulation model was developed to determine the optimal bid and to analyze factors affecting bidding behavior and competition. The tender data indicated there was a surprisingly wide range of bids. Variation of bids across firms submitted for individual HRS tenders had standard deviations that ranged from $5/mt...

PROCUREMENT RISKS AND STRATEGIES TO IMPROVE QUALITY CONSISTENCY IN WHEAT SHIPMENTS AgEcon
Wilson, William W.; Dahl, Bruce L..
Consistency of functional characteristics in wheat is a concern confronting buyers and sellers. This research analyzes the cost and risk of different procurement strategies for importers. A stochastic simulation model is used to determine the probability of a functional characteristic being satisfied subject to quality targets and costs for alternative purchase strategies (purchase by protein only, variety, location, variety by location, or functional tests). Joint probabilities of meeting specifications and costs were determined for the alternative purchase strategies. Stochastic dominance was used to determine which purchase strategies dominate others, and stochastic efficiency was utilized to determine the degree of preference. Results indicate...

VALUATION OF NEW SPRING WHEAT VARIETIES: TRADEOFFS FOR GROWERS AND END-USERS (SUMMARY) AgEcon
Dahl, Bruce L.; Wilson, William W.; Johnson, D. Demcey; Nganje, William E..
Variety release decisions involve a number of tradeoffs, usually between grower and end-user characteristics as well as significant uncertainties about agronomic, quality, and economic variables. In this study, methodologies were developed to value tradeoffs for grower and end-user characteristics for wheat. The models capture effects of variability in agronomic, quality, and economic variables. The models were applied for three experimental varieties which have since been released and for two hypothetical varieties. Results indicate two of the experimental varieties provide improvements in grower and end-use value over most of the incumbents. Comparison of a risk adjusted portfolio model consisting of characteristics of end-use and grower values...

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....

TRANSPARENCY AND BIDDING COMPETITION IN INTERNATIONAL WHEAT TRADE AgEcon
Wilson, William W.; Dahl, Bruce L.; Johnson, D. Demcey.
One of the major trade policy problems identified by U.S. interests, including grower groups, traders, and policymakers, is that of pricing transparency. This has been a gnawing issue generally related to the pricing practices of competitor exporting countries with state trading enterprises (STEs). The transparency problem generally refers to the inability to observe rivals' terms of trade (including price, quality, credit, etc.) and is normally associated with commercial exporters competing against STE rivals. The perception being the less transparent competitors (STEs) would have a strategic advantage. A game theory model of bidding competition was developed to simulate the effects of information asymmetry amongst rivals. A Bayes-Nash equilibrium...

GRADES/CLASSES OF HARD WHEATS EXPORTED FROM NORTH AMERICA: ANALYSIS OF DEMAND AND TRENDS AgEcon
Dahl, Bruce L.; Wilson, William W..
Export patterns for U.S. and Canadian hard wheats (HAD, HRS, HRW, CWRS, and CWAD) were examined. Analysis incorporated grade and non-grade factors from U.S. shipments and grades and classes of Canadian exports. Shift-share analysis was used to examine changes in market shares for classes and grades. Cluster analysis was used to group importers of U.S. wheat classes based on like grade and non- grade factors of wheat shipments. Canada exports most of its hard wheat as No. 1, while the U.S. exports predominately No. 2 or better. Classes experiencing increased market shares include HRS, CWRS, and CWAD. U.S. HRS, HRW, and HAD all showed patterns of increasing market shares for No. 1 over lesser grades from the early 1980s to 1990s. Importer comparisons...

LOGISTICAL COSTS AND STRATEGIES FOR WHEAT SEGREGATION AgEcon
Schlecht, Shannon M.; Wilson, William W.; Dahl, Bruce L..
Special segregations that provide unique qualities for end use products are being specified by buyers. As users of wheat become more specific about quality, the number of quality segregations that the logistical pipeline must accommodate increases. The additional cost of increased grain segregations will influence the optimal level of wheat variety segregations marketed in a supply chain. The primary objective of this research is to develop a model that captures the logistical costs of increased grain segregations in the marketing system. A simulation model was developed to add logistical uncertainty in demand, receipts, rail deliveries, and transit time. Sensitivities were conducted on certain variables to determine their effects on logistical...

Grain Contracting Strategies to Induce Delivery and Performance in Volatile Markets AgEcon
Wilson, William W.; Dahl, Bruce L..
One of the impacts of higher prices along with greater volatility in futures and basis is that there is pressure for an escalation in cash contracting for grain. This volatility has resulted in an unprecedented level of contracting with growers in recent years. There is a wide array of cash contracts with varying terms. There is also a growing realization of growers not delivering on contracts, in part due to escalation in postcontract prices. These are evolving as major strategic issues for buyers and the marketing system, particularly as buyers seek to use such contracting strategies as an element of risk mitigation. There are three purposes of this article. First is to provide a broad survey of contract terms used in grain contracting with growers....

MARKETING MECHANISMS TO FACILITATE CO-EXISTENCE OF GM AND NON-GM CROPS AgEcon
Henry, Benjamin; Wilson, William W.; Dahl, Bruce L..
Development of genetically modified (GM) and specialty crops has had a great impact on the grain handling industry during recent years. Added costs associated with handling these crops have become an important issue for grain handlers. For this study, data were collected from a survey of elevators in the Upper Midwest. The information focused on segregation practices, time requirements, and costs. This study shows the different costs (grading and handling) associated with segregation practices at the grain-handler level. The results revealed that the cost of modifying systems to handle GM is of major importance. A stochastic simulation model of an engineering cost function is developed to analyze costs for segregation and testing using results from the...

MARKETING OF WHEAT ON A CONSTANT AND NIL MOISTURE BASIS AgEcon
Wilson, William W.; Dahl, Bruce L..
This study examined moisture specification practices in the United States and for major exporters and assessed impacts of changes to a nil or constant moisture basis on prices and revenue. These were examined under scenarios where information on moisture in current prices is limited and under a scenario where current prices reflect Full Knowledge of moisture advantages. Results indicate that changing to a nil moisture basis (which requires a subsequent adjustment in volumes to reflect the subtraction of moisture) would increase reported prices from 42 to 70 c/bu for the wheat classes, while changing to a 12 percent constant moisture basis would have limited impacts on reported prices. Effects on relative prices/revenue depend on whether knowledge of...

LOGISTICS AND SUPPLY CHAIN STRATEGIES IN GRAIN EXPORTING AgEcon
Wilson, William W.; Carlson, Donald C.E.; Dahl, Bruce L..
During the past decade, the grain shipping industry has become highly competitive and technologically advanced. These changes, along with the introduction of innovative shipping mechanisms, have made logistics management an important source of opportunity and risk for grain shippers. In this study, a stochastic simulation model was developed to evaluate the tradeoffs and effects of key variables on logistical performance in managing the grain supply chain. Average demurrage cost for the supply chain was $2.03 million with the greatest cost being for railcars and the least cost being for barges. Of the stochastic variables modeled, changes in export demand had the greatest impact on demurrage costs.

OPTIMAL TESTING STRATEGIES FOR GENETICALLY MODIFIED WHEAT AgEcon
Wilson, William W.; Jabs, Eric J.; Dahl, Bruce L..
A stochastic optimization model was developed to determine optimal testing strategies, costs, and risks of a dual marketing system. The model chooses the testing strategy (application, intensity, and tolerance) that maximizes utility (minimizes disutility) of additional system costs due to testing and quality loss and allows simulation of the risk premium required to induce grain handlers to undertake a dual marketing system versus a Non-GM system. Cost elements including those related to testing, quality loss, and a risk premium were estimated for a model representing a grain export chain. Uncertainties were incorporated and include test accuracy, risk of adventitious commingling throughout, and variety declaration. Sensitivities were performed for...

WELFARE IMPLICATIONS OF INTRODUCING BIOTECH TRAITS IN A MARKET WITH SEGMENTS AND SEGREGATION COSTS: THE CASE OF ROUNDUP READY® WHEAT--SUMMARY AgEcon
Wilson, William W.; DeVuyst, Eric A.; Koo, Won W.; Taylor, Richard D.; Dahl, Bruce L..
Roundup Ready® Wheat (RRW) was one of the first genetically modified (GM) traits for the wheat sector and was under review by regulatory agencies in the United States and Canada when Monsanto withdrew it from further consideration. There are a multitude of issues associated with the ex ante evaluation of this decision. These include market acceptance and segregation, as well as the varying sources of cost savings and productivity gains. In this article, we develop a spatial partial equilibrium model of the higher-protein hard wheat market and assess the changes in the distribution of welfare associated with release and adoption of RRW. It incorporates segments for GM aversion in each market and segregation costs for each segment. Major conclusions...
