| When products are differentiated and quality is highly subjective (e.g., fashion or art), novel (e.g., a new feature), or difficult to verify prior to purchase (e.g., credence attributes), consumers may turn to price as a signal of quality. Products containing genetically modified (GM) ingredients meet each of these criteria, i.e., GM ingredients are novel, their presence is difficult to verify, and their impact on subjective quality may be viewed differently across individuals with the same knowledge. We add to the limited empirical literature on consumers' use of price as a quality signal by testing for non-monotonicity of consumer demand in price for GM products using data collected from a nationally representative mail survey featuring several... |

| During the last two decades, product labeling has become an increasingly used policy tool, particularly with respect to the provision of health and environmental information. Theory holds that the flow of information among market participants plays a critical role in the efficient operation of markets. This paper explores the role of product labeling policy in ameliorating two potential market deficiencies: asymmetric information and costly search behavior. Practical considerations for the design and implementation of labeling policy and of labeling research are explored. |

| Nutrient labeling is found to significantly affect consumer purchase behavior; some evidence that consumers may act as if they hold nutrient (or health risk) budgets is found. Providing nutrient information may allow consumers to more easily switch consumption away from "unhealthy" products in those food categories where differences in other quality characteristics (e.g., taste) are relatively small between the more and less "healthy" products, toward "unhealthy" products in categories where differences may be relatively large (i.e., a "substitution effect"). If this substitution effect is large, nutrient labeling may not change the overall consumption of "unhealthy" nutrients and thus may not lead to significant changes in health risk. |

| We provide evidence of consumption externalities for foods with genetically engineered ingredients. The probability of choosing bread made exclusively from genetically engineered wheat is significantly higher for individuals who perceive normal bread to contain higher levels of genetically engineered content. The magnitude and significance of the consumption externality depends upon the intensity and nature of individual concern about genetically engineered foods and upon prevailing information policies such as explicit warnings about potential health impacts of genetically engineered foods. The estimated preference structures result in an equilibrium level of genetically engineered ingredients that can be sensitive to the initial level of genetically... |

| Estimates of the economic benefits of intervention strategies to make food safer from specific pathogens for different durations of protection are not available. We estimated consumers' willingness to pay for a hypothetical vaccine that would deliver a 1-year, 5- years, 10-years, or lifetime protection against Salmonella, E. coli, or Listeria. We used logit and Tobit models to estimate the economic benefits of food safety measures against these major foodborne pathogens. Based on FoodNet 2002 population survey data, consumers were willing to pay for protection against foodborne pathogens. They were willing to pay more for longer protection and for protection against E. coli compared to Salmonella or Listeria. However, they were less willing to pay if... |

| For a representative sample of U.S. consumers, we rank, correlate and explain ratings of concern toward eight food production and processing technologies (antibiotics, pesticides, artificial growth hormones, genetic modification, irradiation, artificial colors/flavors, pasteurization, and preservatives). Concern is highest for pesticides and hormones, followed by concern toward antibiotics, genetic modification and irradiation. We document standard relationships between many demographic, economic and attitude variables and the average concern level. Our main contribution is modeling relative levels of concern across technologies, where we find that key personal and household characteristics that yield little explanatory power for average ratings have... |
