A Comparison between Perception of Risk and Willingness to Serve Genetically Modified Foods AgEcon
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.

ASSESSING NEW-GRADUATE APPLICANTS: ACADEMIC PERCEPTIONS AND AGRIBUSINESS REALITIES AgEcon
Wachenheim, Cheryl J.; Lesch, William C..
This study empirically compares the level of importance assigned to the knowledge, skills, and experiences of applicants for entry-level positions by members of the agribusiness community and how these criteria were perceived by chairpersons of departments of agricultural economics. Chairpersons had a good understanding of criteria important to employers in evaluating applicants and how they prioritize these criteria. Communication and interpersonal skills were ranked as the most important criteria by both groups. Industry members assigned lower levels of importance for formal international training, an attribution largely shared by academic counterparts.

BUILDING AND MAINTAINING A WEBSITE ON-LOCATION AgEcon
Wachenheim, Cheryl J..
Participation in an international study program provides students with invaluable exposure to another culture and a multitude of academic and life experiences. Rapid advances in communication technologies now make it possible for students to share these experiences with their support network at home as they occur. The responsibility of doing so by means of a web page built on-location 1) motivates students to increase their awareness of, and participation in, their surroundings, 2) changes how students view their surroundings and activities in which they participate, 3) increases content learning, 4) extends the number of people involved in the international study program, and 5) results in a professional written and visual documentary.

CANADIAN EXPORTS OF LIVESTOCK AND MEAT TO THE UNITED STATES AgEcon
Mattson, Jeremy W.; Wachenheim, Cheryl J.; Koo, Won W.; Petry, Timothy A..
Canadian exports of beef and live cattle to the United States have increased significantly since the late 1980s. Hog exports have increased since the mid-1990s. Major factors affecting exports of beef, pork, cattle, and hogs from Canada to the United States include the exchange rate, increased Canadian production, U.S.-Canada price differentials, and trade liberalization under the Canada - United States Free Trade Agreement (CUSTA) of 1989. Increased Canadian exports have resulted in small but significant reductions in U.S. domestic prices of beef, pork, and hogs.

CHANGING CONSUMER PERCEPTIONS ABOUT GENETICALLY MODIFIED FOODS AgEcon
Wachenheim, Cheryl J..
University students took part in an experimental auction designed to elicit and estimate the influence of information bias on consumer willingness to pay for GM versus non-GM food products. Surveys before and after the auction queried participants on their perceptions about GM foods and the associated risks, and their beliefs and attitudes about the interaction between farming practices and the environment. Students received either positive- or negative-biased information about the impact of biotechnology on the environment during the auction. Consumer perceptions were influenced by information bias.

CONSUMER VALUATION OF GENETICALLY MODIFIED FOODS AND THE EFFECT OF INFORMATION BIAS AgEcon
Vanwechel, Tamara; Wachenheim, Cheryl J.; Schuck, Eric C.; Lambert, David K..
Bid prices were elicited for standard-label cookies, muffins, and potato chips and those identified as not including genetically modified (GM) ingredients using an experimental auction. Including a statement that the product did not include GM ingredients increased bids over those offered for standard-label products. Providing negative-biased information about the impact of GM crops on the environment increased the risk participants associated with GM foods, and positive-biased information decreased perceived risk. Overall, providing impact information, whether positive- or negative-biased, increased bids for products presumed GM. The influence of information bias on bids varied among selected participant groups, supporting the presence of uniquely...

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

DEMAND ESTIMATION FOR AGRICULTURAL PROCESSING CO-PRODUCTS AgEcon
Novak, Patrick J.; Wachenheim, Cheryl J.; DeVuyst, Eric A.; Lambert, David K..
Co-products of processing agricultural commodities are often marketed through private transaction rather than through public markets or those in which public transaction information is recorded or available. The resulting lack of historical price information prohibits the use of positive time series techniques to estimate demand. Demand estimates for co-products are of value to both livestock producers, who obtain them for use in livestock rations, and processors, who must sell or otherwise dispose of them. Linear programming has long been used, first by researchers and later as a mainstream tool for nutritionists and producers, to formulate least cost livestock rations. Here it is used as a normative technique to estimate step function demand...

ECONOMICS OF ALTERNATIVE STOCKING DENSITIES FOR DIRECT-SEEDED CENTRAL MICHIGAN ALFALFA PASTURES AgEcon
Wachenheim, Cheryl J.; Black, J. Roy; Schelegal, M.L.; Rust, Steven R..
A framework which permits estimation of economically optimal stocking rates for alternative economic parameters and alfalfa forage availability was developed and applied to a controlled grazing experiment conducted with Holstein steers (243 kg) placed on direct seeded alfalfa pastures in Central Michigan. Responses of ADG to alternative levels of forage availability per standard livestock unit (FA) were summarized by a quadratic function and the associated gains/ha were calculated. The ADG decreased as standard stocking rate (SSR; SLU/ha) increased except for the combination of the lowest observed SSR and highest FA, where ADG was curvilinear as SSR increased. The trend for gain/ha was curvilinear for all FA. The SSR which maximized gain/ha increased...

Estimating Price Premiums for Breads Marketed as “Low-Carbohydrate Breads” AgEcon
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.

GROWING AND MAINTAINING VIABLE STUDENT CHAPTERS OF PROFESSIONAL ORGANIZATIONS: THE CASE OF THE NATIONAL AGRIMARKETING ASSOCIATION AgEcon
Wachenheim, Cheryl J..
There are 35 accredited student chapters of the National AgriMarketing Association (NAMA) from 24 states and 3 Canadian Provinces. Membership in a NAMA student chapter allows students to network with professionals, develop their marketing and communication skills, and develop leadership and team-building skills. A survey of student chapter advisors was used to identify what facilitates and what constrains student chapter success. Advisors indicated the opportunity and enjoyment of the national conference and professional and career development opportunities to be the most important reasons students participate in student NAMA. The opportunity to network with professionals, they noted to be the most important advantage of participation, followed by...

HOW AN ONLINE COURSE COMPARES AgEcon
Wachenheim, Cheryl J..
Student satisfaction with and performance in an online agrisales course is compared with that of students enrolled in a simultaneously-taught classroom course. Assessment tools are developed for both sections. Online and classroom students were equally satisfied with the course and the instructor using most measures, but had different motives for course enrollment. Overall student performance did not differ. However, online students tended to do better on exams and homework assignments while classroom students demonstrated a greater ability to apply course concepts to a practical setting. Results suggest instructors be well-prepared to handle unique learner situations prior to marketing an online course and work to ensure students are motivated to...

Identifying Market Preferences for High Selenium Beef AgEcon
Hovde, Scott C.; Wachenheim, Cheryl J.; Hearne, Robert R.; Nganje, William E..
Selenium is an element found in relatively high concentrations in crops and livestock raised on high-selenium soils located in North and South Dakota. Evidence suggests that a high-selenium diet such as would be obtained from consuming these products can reduce the risk of certain cancers. The region's livestock and grain producers are exploring potential high-selenium product marketing opportunities. A choice experiment was conducted to identify preferred attributes for a high-selenium beef product and the characteristics of potential market segments. In a national survey, participants chose between different levels of health claim approval and research, prices, and selenium origin. A multinomial logit regression model was estimated. Labeling...

ISSUES IN DEVELOPMENT AND ADOPTION OF GENETICALLY MODIFIED (GM) WHEATS AgEcon
Wilson, William W.; Janzen, Edward L.; Dahl, Bruce L.; Wachenheim, Cheryl J..
Development of genetically modified (GM) wheat varieties is proceeding; however, several critical issues remain the focus of contention. This project summarizes the current state of knowledge on some of these critical issues for commercialization of GM wheats. Background on the evolution of GM Wheats is presented. Then, agronomic adoption and competitiveness of GM crops; research on GM traits in wheat; consumer acceptance of GM crops (a separate section is included on issues related to consumer acceptance of GM crops); regulatory issues and status; international trade; testing, segregation, and identity preservation; and production and marketing risks are examined. Finally, there is a description of the likely marketing system to evolve and a...

Learning from Assessment: Effect of Changes in an Online Course on Students' Perceptions and Performance AgEcon
Wachenheim, Cheryl J..
Student satisfaction with, and performance in, a first-offer online agrisales course was compared with that of students enrolled in a simultaneously-taught classroom course. Online and classroom students were equally satisfied with the course and the instructor using most measures, and student overall performance did not differ. However, online students tended to do better on exams while classroom students demonstrated a greater ability to apply course concepts to a practical setting. Changes were made in the online course to improve student understanding of and ability to apply course concepts. Specifically, online student exams were no longer open-note / open-book and were proctored. On-campus online students also participated in their final sales...
