A Comparison between Perception of Risk and Willingness to Serve Genetically Modified Foods 31
Nganje, William E.; Wachenheim, Cheryl J.; Lesch, William C..
The dichotomy between perceptions of the acceptability of risk associated with genetically modified (GM) foods and willingness to consume GM foods is investigated. Results indicate that some consumers are willing to consume GM foods even though they may perceive such foods as somewhat unsafe, with determinants such as self-perceived knowledge about the availability of GM foods and altruistic motives having positive and significant effects on their consumption decisions. Efforts toward decreasing perception of risk and ultimately increasing acceptance of and demand for GM foods should address issues related to their altruistic characteristics and outrage.

Agro-terrorism and the Grain Handling Systems in Canada and the United States 31
Nganje, William E.; Wilson, William W.; Nolan, James F..
The grain handling sector in Canada and the United States is vital to agriculture and trade. In a typical year on the Canadian prairies, about 140,000 producers deliver some 20 to 30 mmt of grain for export to primary elevators. In the United States, about 2.1 million producers deliver about 300 mmt of grain to primary elevators. Canadian grain is moved to export position using more than 400,000 hopper cars and marine containers, where about 1,200 ships per year are loaded. In the United States, about 1.08 million rail carloads of grain are originated per year, and about 23 mmt of grain are shipped on barges per year. These U.S. figures are in addition to trucks, which, more so than in Canada, are also used to deliver grain to primary processors and to...

Consumer Willingness to Pay for Breads Marketed as "Low-Carbohydrate" 31
Wachenheim, Cheryl J.; Nganje, William E.; Kaitibie, Simeon; Johnston, Gretchen.
Bread producers are taking advantage of healthy feeding habits by developing new "low carbohydrate" products to entice customers. These low carbohydrate breads are generally more expensive than conventional types. This study tests the hypothesis that consumers are willing to pay higher premium for "low carbohydrate" breads at various locations and markets. We use retail data in a hedonic pricing framework to estimate the premium paid for the "low carbohydrate" attribute of bread. Results show that the implicit price of the "low carbohydrate" attribute of bread ranges from about 0.06¢ to 1.1¢ per gram, reflecting the amount consumers are willing to pay above the price of conventional bread.

CROP INSURANCE UNDER QUALITY UNCERTAINTY 31
Nganje, William E.; Tiapo, Napoleon M.; Wilson, William W..
Quality related yield and price losses have had significant impact on producer income and risks, and in some instances exceeded yield and price losses covered by conventional insurance instruments. However, there are no effective third party quality risk transfer mechanisms especially for barley growers. In this paper, we develop a framework to incorporate quality-related risk in crop insurance programs. Specifically, we derive the optimum equilibrium coverage levels and risk premium that suppliers of insurance and producers would be willing to provide when the yield and revenue insurance instruments explicitly incorporate quality losses. The results of our analysis provide several important contributions. First, the methodology illustrates how quality...

ECONOMIC ANALYSIS OF THE PROPOSED NORTH DAKOTA WHEAT POOL 31
Koo, Won W.; Nganje, William E.; Johnson, D. Demcey; Park, Joon J.; Taylor, Richard D..
The ND Durum Wheat Pool may provide additional revenue to durum wheat producers by raising the domestic prices in the North American market with full cooperation from the Canadian Wheat Board. The pool also could provide additional revenue to its members by improving marketing efficiency. On the other hand, the ND Spring Wheat Pool is less likely to provide additional revenue to spring wheat producers by raising domestic prices, mainly because hard red spring and winter wheat are highly substitutable. Efficiency gains also could be smaller than for durum wheat.

Economic Impact of Fusarium Head Blight in Malting Barley: Blending Margins and Firm-Level Risk 31
Nganje, William E.; Johnson, D. Demcey.
FHB and DON present significant challenges to producers, grain elevators, and the brewing industry. Yield reductions and price discounts incurred by producers in North Dakota, Minnesota, and South Dakota averaged about $45.3 million annually during the years 1998 through 2000. Losses are more substantial when secondary economic impacts are considered. For every $1 of scab losses incurred by the producer, $2 in losses are incurred in other areas of rural and state economies. One way of mitigating these losses is to blend barley with DON and barley without DON. Results from the grain blending model show a sharp decline of DON discounts and losses after blending. The average discount fell from $0.57/bu to $0.17/bu in 1998, $0.48/bu to $0.14/bu in 1999, and...

ECONOMIC IMPACT OF SCAB WITH ALTERNATIVE RISK MANAGEMENT STRATEGY: THE CASE OF CROP QUALITY INSURANCE IN BARLEY 31
Nganje, William E.; Tiapo, Napoleon M.; Wilson, William W..
Managing quality risks, especially grain quality, has been a challenge facing farmers, grain merchandisers, and policymakers for many years. With the advent of genetically modified organisms (GMOs), food safety, and identity preservation, this is even more challenging today. In this paper, an equilibrium crop insurance model was developed and used to analyze the impact of quality risks on equilibrium coverage levels and risk premiums that suppliers of insurance and barley producers would be willing to provide when yield and revenue insurance instruments explicitly incorporate quality risks. The asking price concept and sensitivity analysis were used to evaluate farmers' behavior after they purchase crop quality insurance and to provide guidance and...

ECONOMIC IMPACTS OF FUSARIUM HEAD BLIGHT IN WHEAT AND BARLEY: 1993-2001 31
Nganje, William E.; Kaitibie, Simeon; Wilson, William W.; Leistritz, F. Larry; Bangsund, Dean A..
Fusarium Head Blight (FHB), commonly known as scab, has been a severe problem for wheat and barley producers since 1993. This study provides an update of economic losses suffered by wheat and barley producers in scab-affected regions in the United States. Emphasis is placed on estimating direct and secondary economic impacts of yield and price losses suffered by wheat and barley producers from 1993 to 2001. Nine states are included in the analysis for three wheat classes. Three of the nine states were also used for the analysis of malting and feed barley. The cumulative direct economic losses from FHB in hard red spring (HRS) wheat, soft red winter (SRW) wheat, durum wheat, and barley are estimated at $2.492 billion from 1993 through 2001. The...

EFFICIENT QUANTITATIVE RISK ASSESSMENT OF JUMP PROCESSES: IMPLICATIONS FOR FOOD SAFETY 31
Nganje, William E..
This paper develops a dynamic framework for efficient quantitative risk assessment from the simplest general risk, combining three parameters (contamination, exposure, and dose response) in a Kataoka safety-first model and a Poisson probability representing the uncertainty effect or jump processes associated with food safety. Analysis indicates that incorporating jump processes in food safety risk assessment provides more efficient cost/risk tradeoffs. Nevertheless, increased margin of safety may lead to reduction in food safety expenses on areas that have relative advantage in reducing mean risk. The paper also develops an alternative measure for the value of risk reduction associated with uncertainty of jump processes and the cost of food safety.

Estimating Price Premiums for Breads Marketed as “Low-Carbohydrate Breads” 31
Nganje, William E.; Kaitibie, Simeon; Wachenheim, Cheryl J.; Acquah, Emmanuel T.; Matson, Joel; Johnson, Grant.
Retail data are used in a hedonic pricing framework to estimate the premium paid for the “low-carbohydrate” attribute and other attributes of bread at grocery and non-grocery stores in a regional market. Results show that consumer willingness to pay is influenced by the “low-carbohydrate” attribute as well as by sugar, fiber, and fat content; serving size; and size of loaf. Implicit price premiums vary significantly by retail location. However, price differentials may be compounded by the absence of an acceptable definition for low-carbohydrate foods.

FARMER EDUCATION AND ADOPTION OF SLASH AND BURN AGRICULTURE 31
Schuck, Eric C.; Nganje, William E.; Yantio, Debazou; Aquach, Emmanuel.
Education can play a critical role in moving farmers in developing countries away from environmentally harmful slash and burn agriculture. The present research examines the extent to which extension education can promote adoption of cropping systems other than slash and burn. Choice of cropping system by farmers in Cameroon, whether slash and burn, multiple crops, or mono-cropping, is modeled as a function of farm size, farmer educational level, and visits by extension personnel. Results indicate that higher visitation rates by extension personnel reduce not only the likelihood of farmers choosing slash and burn agriculture, but also promotes movement into mono-cropping. Since mono-cropping represents a move toward export-oriented agriculture in...

Food Recalls and Food Safety Perceptions: The September 2006 Spinach Recall Case 31
Onyango, Benjamin M.; Miljkovic, Dragan; Hallman, William K.; Nganje, William E.; Condry, Sarah C.; Cuite, Cara L..
This paper examines public perceptions on food safety particularly relating to spinach, which was subject of countrywide recall in 2006. Results indicate that food safety perceptions may be driven by public trust/confidence in institutions whose activities may be directly or indirectly related to food safety. The results further suggest that food safety perceptions may also be related to the type of the product; for example, the public perceives frozen spinach differently from bagged fresh spinach. Additionally, the results show that low levels of objective knowledge about food pathogens and the resulting illnesses have implications on overall food safety. Results further indicate that females and Caucasians perceived the four types of spinach as safe for...

Food Recalls and Food Safety Perceptions: The September 2006 Spinach Recall Case 31
Onyango, Benjamin M.; Miljkovic, Dragan; Hallman, William K.; Nganje, William E.; Condry, Sarah C.; Cuite, Cara L..
This study analyzes public perceptions of food safety using a national survey conducted in November 2006, soon after the September 2006 nationwide spinach recall. We explore relationships between peoples’ perceived risks of food contamination (spinach in this case) and their trust in the institutions in charge of safeguarding/ensuring safety. Finally, we examine relationships between individual observance of basic good food handling practices and food safety. Trust in institutions through which food passes and regulatory agencies were shown to be critical in determining food safety perceptions. For example, confidence in the USDA as a regulatory agent was viewed positively, and hence contributed toward viewing the four types of spinach as safe for...
