Malnutrition and food deprivation, which are concentrated in poor countries, have been a long-term concern of economists, but as per capita income in developed countries has grown in the 20th century, a new problem of over-nutrition leading to obesity has occurred. This paper develops models of...

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...

Over the past thirty-five years, the U.S. adult obesity rate has more than doubled from roughly 15% to 35%, reflecting a general diffusion of obesity across all segments of the adult population (USDHHS). Obesity is a concern because it increases the risk for cardiovascular diseases, diabetes,...

Controversy surrounds the introduction of genetically modified foods. One key issue relates to tolerance levelsï¾—the impurity rate tolerated before a commodity must be labeled. Currently, the United States has not defined a tolerance level for genetically modified foods. This paper uses...

In most environments, information is critical to consumersï¾’ decision making. Consumers have prior beliefs about quality and price of goods and services and obtain new information which is used to update these prior beliefs or to form posterior beliefs, i.e., Bayesian learning. New food...

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...

To be effective, groups that disseminate information need the trust of consumers. When multiple groups provide conflicting information on a new product or process like GM-foods, consumers place different levels of trust in the various sources. We present a model of the contributions of personal...

Genetically modified (GM) foods have been engulfed in considerable controversy, and the early optimism has been dampened. Information issues--labeling and asymmetric information--are central to the GM-food debate. Furthermore, it is important to understand the reaction in developed countries to...
