| The effect of negative information on consumer product evaluations has been studied heavily in the context purchase intentions and other preference-related measures. In this study, we examine the context (negative health hazard information on meat commodities), direction (positive and negative), and intensity (low and high) of information on consumer choice processes. We draw from the literature on Bayesian updating, choice processes and heuristics, as well as cognitive and information processing to propose a set of hypotheses and empirically test them using survey data. Our results indicate that under low intensity, information consumers tend to employ a non-compensatory type choice process with the health aspects of the product being nonsalient. In the... |

| This study presents a framework to analyze how uncertainty about product attributes affects consumers' WTP for brand name products over generic ones, incorporating key elements of a random utility model and product attribute models. We found that in comparison to electronics, clothing, and processed food, consumers buy brand name vegetables and fruits mainly because of quality uncertainty, and they can easily reduce uncertainty of product quality of fresh vegetables and fruits by seeing, touching, smelling, and tasting. Hence, consumers are less willing to pay for brands of fresh vegetables and fruits. However, simulation results show that brands of fresh fruits and vegetables may have a similar price premium as other products, but they lack the market... |

| This paper analyzes the effect of competition on product demonstration decisions. Pre-purchase product demonstration enables marketers to differentiate products that are ex-post differentiated but are judged according to perceived fit, rather than actual fit, due to pre-purchase consumer uncertainty. Imbalanced competition accompanied by fit uncertainty motivates the follower to offer demonstrations to avoid a price war. This paper explores the conditions that lead the leader to retaliate. In addition to effects on quantity, competition may increase the quality of demonstrations offered by the leader. We analyze a business case, showing that competition may increase the demonstration intensity and that the leading manufacturer’s response to changes in... |

| While the demand for traditional agricultural economics is diminishing, there is a growing need for the economics and management of the food sector and the environment. Departments of agricultural economics have shown great flexibility in including agribusiness in their Bachelor's and Master's teaching programs. Ph.D and research programs appear to adjust more slowly to changing demand. Although agricultural economics programs are providing a variety of service course offerings, opportunities for joint programs with biological, physical, and natural sciences, particularly resource management, are not being exploited. If business schools decide to compete for agribusiness students in the future, missed opportunities with other departments and schools may... |

| Economic research generates a wide array of benefits. These include information, technological change, and improved policy. There are few quantitative studies of the benefits of economic research, and some benefits may be misattributed to biological and physical research. To be productive, economic research must be transmitted and the user must be able to use it. Therefore, investment in extension outreach and economic literacy are important to improve its impact. Even casual observation suggests that economic research is valuable, but noneconomists must be convinced of this. Since benefits are likely to be concentrated in a small number of successful projects, a useful approach to the assessment of the benefits of research is to identify these projects... |
