AGRICULTURAL LAND USE CHOICE: A DISCRETE CHOICE APPROACH AgEcon
Claassen, Roger; Tegene, Abebayehu.
A discrete choice model and site-specific data are used to analyze land use choices between crop production and pasture in the Corn Belt. The results show that conversion probabilities depend on relative returns, land quality, and government policy. In general it is found that landowners are less inclined to remove land from crop production than to convert land to crop production.

AGRICULTURE IN AN ECOSYSTEMS FRAMEWORK AgEcon
Aillery, Marcel P.; Hrubovcak, James; Kramer, Carol S.; Shoemaker, Robbin A.; Tegene, Abebayehu.
By broadening the definition of an ecosystem to include economic activities, can we better characterize the interactions and relationships among agricultural activities and important indicators of ecological system health? This paper addresses research approaches for assessing the role of agriculture in an ecosystems context. Environmental regulation and resource management policies have heightened the interest in understanding interactions among agricultural activities and the natural resource base, including the impacts of agriculture on environmental quality and the impacts on agriculture of ecosystem restoration efforts. What are the most meaningful indicators of environmental quality? Which agricultural practices and policies should be considered,...

ARE U.S. CONSUMERS TOLERANT OF GM FOODS? AgEcon
Rousu, Matthew C.; Huffman, Wallace E.; Shogren, Jason F.; Tegene, Abebayehu.
Genetically modified (GM) foods have caused many controversies. One important controversy relates to tolerance - the impurity rate that is tolerated before a commodity must be labeled as genetically modified. Currently, the United States does not have a specific tolerance or threshold level for GM foods. This paper uses experimental auctions to determine consumers' acceptance of non-GM foods with zero, 1 percent, and 5 percent tolerance for genetically modified material. Our results indicate that consumers would pay less for food that tolerates GM material, but the discount is not significantly different for foods with 1-percent and 5-percent GM content.

ARE US CONSUMERS TOLERANT OF GM FOODS? AgEcon
Rousu, Matthew C.; Huffman, Wallace E.; Shogren, Jason F.; Tegene, Abebayehu.
Many countries require labeling for GM food products. These countries often have different levels of genetic modification that they will tolerate before a food product must be labeled as genetically modified. For example, the European Union and Australia allow up to one percent of any ingredient in a food product to be GM before the product must be labeled as genetically modified. Japan allows 5% of any ingredient to be genetically modified before the product must be labeled as such. The United States currently does not require mandatory labeling of GM labeled foods and has no standards for what percentage of an ingredient in a food product can be genetically modified for the product to still be labeled non-GM. For the official "organic"...

BETTER DEAD THAN GM-FED? INFORMATION AND THE EFFECTS OF CONSUMERS' RESISTANCE TO GM-FOODS IN HIGH-INCOME COUNTRIES AgEcon
Huffman, Wallace E.; Rousu, Matthew C.; Shogren, Jason F.; Tegene, Abebayehu.
This paper addressed the puzzling resistance of Presidents of southern African countries to food aid in 2002, given near certain starvation and long-term negative health effects of malnutrition of their constituents. First, I show that NGOs led by Greenpeace and Friends of the Earth are disseminating information claiming that GM foods are dangerous to human health and are "Frankenfoods." Second, people in European Union countries, who are not in any danger of starvation, have strong preferences for non-GM foods, which they can easily afford. Over the long term, however, the tastes of EU consumers matter to southern African countries because some of these countries hope to export agricultural products in the future. GM-food aid, which most likely would...

Consumer Willingness to Pay for Genetically Modified Food Labels in a Market with Diverse Information: Evidence from Experimental Auctions AgEcon
Huffman, Wallace E.; Shogren, Jason F.; Rousu, Matthew C.; Tegene, Abebayehu.
With the continuing controversy over genetically modified (GM) foods, some groups advocate mandatory labeling of these products, while other groups oppose labeling. An important issue is how GM labels affect consumers' willingness to pay for these food products in the market. Using a statistically based economics experiment with adult consumers as subjects, we examine how willingness to pay changes for three food products--vegetable oil, tortilla chips, and potatoes--when GM labels are introduced. Participants in the experiments discounted GM-labeled foods by approximately 14% relative to their standard-labeled counterparts. The evidence also showed that sequencing of food labels affects willingness to pay, and that randomizing treatments is an important...

CONSUMERS' RESISTANCE TO GENETICALLY MODIFIED FOODS IN HIGH INCOME COUNTRIES: THE ROLE OF INFORMATION IN AN UNCERTAIN ENVIRONMENT AgEcon
Huffman, Wallace E.; Rousu, Matthew C.; Shogren, Jason F.; Tegene, Abebayehu.
This paper examines the market characteristics that push consumers in high income countries to resist GM foods, with an emphasis on negative information from environmental groups and third-party, verifiable information. For this study, unique data were collected from adult consumers in the United States who participated in laboratory auctions of three food types with randomly assigned labeling and information treatments. Using U.S. consumers is important because U.S. consumers are generally supportive of GM foods and free from the BSE "food scare" fears and bias towards "natural" that are hypothesized to lead Europeans to reject GM foods. Key findings are that negative GM-product information supplied by environmental groups pushes some consumers out of...

DID BSE ANNOUNCEMENTS REDUCE BEEF PURCHASES? AgEcon
Kuchler, Fred; Tegene, Abebayehu.
This study examines consumers’ retail purchases of beef and beef products for evidence of a response to the 2003 U.S. government announcements of finding cows infected with Bovine Spongiform Encephalopathy (BSE). We constructed weekly estimates of quantities of beef products consumers purchased from 1998 through 2004 using ACNielsen Homescan data. While the variance in purchases was large, most could be explained by trend and seasonality. Deviations from established purchase patterns following the BSE announcements varied across beef products, but were limited to no more than 2 weeks in all cases.

DOES EXTENSION WORK? IMPACTS OF A PROGRAM TO ASSIST LIMITED-RESOURCE FARMERS IN VIRGINIA AgEcon
Akobundu, Eberechukwu; Alwang, Jeffrey Roger; Essel, Albert E.; Norton, George W.; Tegene, Abebayehu.
Qualitative evidence suggests that 1890 institutions play a significant role in delivering extension information to limited-resource, particularly minority, farmers. However, there is little empirical evidence of economic impacts of public investments in 1890 extension programs. This paper quantifies the economic impacts of the 2501 extension program for limited resource farmers in Virginia.

FARMLAND PROTECTION: THE ROLE OF PUBLIC PREFERENCES FOR RURAL AMENITIES AgEcon
Hellerstein, Daniel; Nickerson, Cynthia J.; Cooper, Joseph C.; Feather, Peter; Gadsby, Dwight M.; Mullarkey, Daniel J.; Tegene, Abebayehu; Barnard, Charles H..
Public amenities provided by a rural agricultural landscape, arising from open space and farm activity, are important to many citizens and policymakers. Widespread development of farmland in some parts of the country has spawned an expanding array of farmland protection programs by county, State, and Federal governments, as well as by nonprofit organizations. To investigate the relative importance of preserving different amenities, this report examines the enabling legislation of these programs across the 48 contiguous States, and the implementation of these programs in five Northeastern States (Maryland, Massachusetts, New Jersey, Pennsylvania, and Vermont). The report also assesses how farmland protection programs fit into the broader array of rural land...

OBESITY AND NUTRIENT CONSUMPTION: A RATIONAL ADDICTION? AgEcon
Richards, Timothy J.; Patterson, Paul M.; Tegene, Abebayehu.
This study tests for a rational addiction to food nutrients as a potential explanation for the obesity epidemic. A random coefficients (mixed) logit model applied to household scanner data finds evidence of a strong, forward-looking addiction to carbohydrates. Consequently, price-based policies may be effective in controlling excessive nutrient intake.

Obesity and Nutrient Consumption: A Rational Addiction? AgEcon
Richards, Timothy J.; Patterson, Paul M.; Tegene, Abebayehu.
Widespread obesity in the U.S. is a relatively recent phenomenon, reaching epidemic proportions only in the last 15 years. However, existing research shows that while calorie expenditure through physical activity has not changed appreciably since 1980, calorie consumption has risen dramatically. Consequently, any explanation of obesity must address the reason why consumers tend to overeat in spite of somewhat obvious future health implications. This study tests for an addiction to food nutrients as a potential explanation for the obesity epidemic. Specifically, we use a random coefficients (mixed) logit model applied to household scanner data to test a multivariate version of the rational addiction model of Becker and Murphy and Chaloupka. We find evidence...

SHOULD THE UNITED STATES INITIATE A MANDATORY LABELING POLICY FOR GENETICALLY MODIFIED FOODS? AgEcon
Huffman, Wallace E.; Rousu, Matthew C.; Shogren, Jason F.; Tegene, Abebayehu.
In many countries, including those in the European Union, Japan, Australia, and China, labeling is required for foods that contain genetically modified material. Other countries, including the United States, do not require mandatory labeling of GM foods. The United States, however, does allow firms to voluntarily label their products as non-GM. This raises the question of whether a mandatory labeling or voluntary labeling policy is more efficient. Proponents of voluntary labeling policies say they are less expensive, because only the firms that wish to label their products must incur the labeling costs. In a mandatory labeling regime, all firms would need to incur additional costs, whether the costs are due to product testing, label design,...

SHOULD THE UNITED STATES REGULATE MANDATORY LABELING FOR GENETICALLY MODIFIED FOODS? AgEcon
Huffman, Wallace E.; Rousu, Matthew C.; Shogren, Jason F.; Tegene, Abebayehu.
Public debate continues over whether the United States should regulate genetically modified (GM) foods by imposing a mandatory labeling policy. This paper develops a model that shows that a voluntary GM-labeling policy results in higher welfare than a regulated mandatory GM-labeling policy, if consumers can accurately read the signals in each market. We then develop an experiment that shows consumers behave as if they can accurately identify signals for GM foods. Our model and results support the perspective that the United States has been prudent in fending off calls for regulations demanding a mandatory GM-labeling policy.

Taxing Snack Foods: What to Expect for Diet and Tax Revenues AgEcon
Kuchler, Fred; Tegene, Abebayehu; Harris, James Michael.
Health researchers and health policy advocates have proposed levying excise taxes on snack foods as a possible way to address the growing prevalence of obesity and overweight in the United States. Some proposals suggest higher prices alone will change consumers' diets. Others claim that change will be possible if earmarked taxes are used to fund an information program. This research examines the potential impact of excise taxes on snack foods, using baseline data from a household survey of food purchases. To illustrate likely impacts, we examine how much salty snack purchases might be reduced under varying excise tax rates and possible consumer price responses. We find that relatively low tax rates of 1 cent per pound and 1 percent of value would not...

The Economics of Obesity-Related Mortality among High Income Countries AgEcon
Huffman, Wallace E.; Huffman, Sonya Kostova; Tegene, Abebayehu; Rickertsen, Kyrre.
The high and rapidly rising adult obesity rates in the United States, United Kingdom, Australia and New Zealand are associated with major health risks, including cardiovascular disease, diabetes, stroke, and some forms of cancer; large health care costs; and premature deaths annually. For example, the death rate from diabetes mellitus has been rising in the U.S. In contrast, death rates from circulator diseases have a strong negative trend, but rising obesity rates almost certainly have slowed this trend. This paper focuses on obesity-related mortality from diabetes and circulatory diseases and establishes the econometric underpinning of an aggregate household health production function and an aggregate household health supply function using data for 15...

THE EFFECTS OF INFORMATION ON CONSUMER DEMAND FOR BIOTECH FOODS: EVIDENCE FROM EXPERIMENTAL AUCTIONS AgEcon
Tegene, Abebayehu; Huffman, Wallace E.; Rousu, Matthew C.; Shogren, Jason F..
Consumers' willingness to pay for food products decreases when the food label indicates that a food product is produced with the aid of modern biotechnology. This bulletin presents empirical evidence on consumers' willingness to pay for biotech foods based on the presence or absence of labels advising that the food was prepared with the aid of biotechnology. The authors designed and conducted an experimental auction to elicit consumers' willingness to pay for "genetically modified" (GM)-labeled and standard-labeled foods under different information regimes. The evidence gathered for vegetable oil, tortilla chips, and potatoes shows that labels matter. In particular, under all information treatments, consumers discounted food items labeled "GM" by an...
