While Ethiopia is Africa’s largest livestock producer, sanitary and phytosanitary (SPS) barriers and animal diseases have traditionally constrained market access. A system dynamics model examined the feasibility of a proposed SPS certification system under a number of scenarios. Model results indicate that the system may not be viable for beef exports to Middle Eastern markets. However, the binding constraint is high domestic input costs rather than the costs of SPS compliance. Sensitivity analyses reveal that while investments in feed efficiency and animal productivity would enhance Ethiopia’s export competitiveness, the competitive nature of international beef markets may still prevent market access.

Consumer Willingness to Pay for Breads Marketed as "Low-Carbohydrate"

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.

Dual-purpose winter wheat production is an important economic enterprise in the southern Great Plains of the United States. Because of the complex interactions involved in producing wheat grain and beef gain from a single crop, stocking density is an important decision. The objective of the research is to determine the stocking density that maximizes expected net returns from dual-purpose winter wheat production. Statistical tests rejected a conventional linear-response plateau function in favor of a linear-response stochastic plateau function. The optimal stocking density of 1.48 steers per hectare (0.60 steers per acre) is 19% greater with a stochastic plateau than with a nonstochastic one.

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...

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.

FOOD SAFETY RISK PERCEPTION AND CONSUMER CHOICE OF SPECIALTY MEATS

Nganje, William E.; Kaitibie, Simeon.

Consumer perception issues and recent microbial outbreaks in the livestock industry continue to stifle demand for specialty meats in the United States. This study was designed to explore impacts of risk perception issues on consumer choice of bison meat. A stated preference discrete choice random utility model, a joint risk perception/product choice model, and a probability of frequency method to aggregating risk scenarios, were used for a range of food safety/certification regimes. Perceived risk reduces bison consumption, but its effect declines with shifts to more regulatory control inherent in the different certification regimes.

This study was conducted to determine risk efficient production strategies for crop and livestock producers who have the opportunity to produce wheat as a dual-purpose forage and grain crop. Empirical data obtained from field trials were incorporated into an integrated crop and livestock production and marketing risk programming model.

INVESTOR'S EXPECTATIONS OF NEW GENERATION COOPERATIVES' EQUITY

New Generation Cooperatives (NGCs) or value-added agricultural cooperatives are undergoing several structural changes with the acceptance of outside (non-farmer) investor equity and demutualization or transformation into investor-oriented ownership firms (e.g., Limited Liabilities Cooperatives (LLCs) to ameliorate perceived financial constraints for high technology investments. These changes introduced added complexity to investors' expectations of equity and to the valuation of NGC and LLC stocks, especially for stock traded among members. Current stock valuation methods do not capture NGC-specific characteristics such as social capital, liquidity constraints, and ongoing demutualization to LLCs. Social capital is the premium paid for non-monetary...

This study uses a Cox parametric bootstrap test to select between two specifications of the von Liebig hypothesis, a switching regression model and a non-linear mixed stochastic plateau function. The selected production function was used to determine optimal stocking density for dual-purpose winter wheat, under production and output price uncertainty. The switching regression approach was rejected in favor of the non-linear mixed stochastic plateau function. The relatively small difference in optimal stocking density between risk aversion and risk neutrality suggests that risk-aversion is much less important in explaining producer response to uncertainty than is nonlinearity in the production function.

Reasonably high stocking densities generally lead to high profit for steer grazing enterprises. However, higher stocking densities result in high microbial counts, creating food safety concerns, especially with the advent of BSE in recent years. This study explores the impact of production and output price uncertainty on optimal stocking density when microbial shedding presents a food safety problem. The optimal grazing pressure is based on the expected utility maximization framework, and a stochastic linear response and plateau production function. Results show that uncertainty and food safety problems lead to lower stocking density, and lower profits. However, reducing the potential incidence of microbial shedding guarantees future profits to the...

The East African Customs Union was established in 2005 with the aim of increasing intraregional trade. The Customs Union protocol commits member states to eliminate non-tariff barriers (NTBs) to intraregional trade. However, several NTBs are still applied by member states. This study identifies the existing NTBs on maize and beef trade and quantifies their impact on trade and welfare of EAC citizens using a Spatial Equilibrium Model (SEM). Data on NTBs were collected from traders and transporters of maize and beef cattle in East Africa. Roadblock checks, bribes and custom rules and procedures were identified as the main NTBs to trade. The SEM model shows that a 50% reduction of the cost of NTBs, or their complete elimination would improve social welfare in...

Food safety risks and microbial outbreaks have significant health impacts on society as a whole, as well as economic loss to food processing firms. According to the U.S. Centers for Disease Control (CDC), an estimated 76 million foodborne illnesses occur each year in the United States. Of these cases, 325,000 hospitalizations and 5,000 deaths occur each year (Mead et al., 1999). The U.S. Department of Agriculture, Food Safety and Inspection Services (USDA-FSIS) (1996) estimated that approximately 4,000 deaths each year are attributed to contamination in meat and poultry products. For food processing firms, microbial outbreaks often result in significant economic losses: food recalls, lost market share, and decreased consumer confidence. The intangible...
