| This article introduces a discrete choice model which incorporates a nonlinear structural adjustment to the standard utility coefficients or decision weights. The proposed model is theoretically and empirically appealing when compared to several alternative approaches, and it can be estimated by conventional maximum likelihood. Application of the proposed model in a case study shows that it outperforms two competing approaches in model fit. Given its simplicity, this model is also capable of revealing consumers' heterogeneous choices. It is shown that based on consumers' different characteristics, their product choice and its welfare implications are also potentially different. |

| This research furthers the assessment of consumer demand for locally produced foods, while also considering a host of other food attributes that may interact to influence consumer utility. Using stated preference data from a choice-based conjoint analysis survey instrument, we estimate willingness-to-pay for processed food products (blackberry jam) that are differentiated with respect to their branding, the location of their production, certification as organically produced, branding as a product of a small family farming association, and carrying a State Proud certification. Although price is the most important single attribute influencing consumer choice for our sample, consumers also were willing to pay more for food products produced in their state or... |

| We assess Canadian’s risk perceptions for genetically modified (GM) food and probe influences of socio-economic, demographic and other factors impinging on these perceptions. An internet-administered questionnaire with two stated choice split-sample experiments that approximate market choices of individual grocery shoppers is applied to elicit purchase behavior from 882 respondents across Canada. Data are collected to assess the influence on respondents’ choices for a specific food product (bread) of 1) product information which varies in content and by source and 2) information provided through labeling. These data also enable: a) analysis of trade-offs made by consumers between possible risks associated with GM ingredients and potential health or... |

| This study incorporates reference point effects into a stated choice survey of consumer demand for food with credence attributes. Parametric tests can be applied to the utility function to examine the existence of reference price effects. Results are consistent with prospect theory in that consumers exhibit strong and nonlinear reference price effects, with cheaper prices receiving less decision weight than higher prices. The underlying utility function is concave over lowered prices and convex over increased prices, with diminishing sensitivity in both domains. The study, however, did not find experience or consumers' attitudes to be significant in explaining reference price effects. |

| In combination with the emergence of genetically modified (GM) food, there has been an urgent call for GM labeling to provide relevant information disclosure. Using data collected in Beijing, China, this study attempts to address the issue of whether different types of information may have distinct impacts on consumers’ stated purchasing decisions. Three types of information are used in this study: one is generic and the other two are linked with two important implications of GM technology—human health and the environment. Results verify that consumers’ purchasing decisions are affected by different types of information through their attitudes and personal characteristics. This finding has potential implications for establishing various GM marketing... |

| Conventionally, studies examining the impacts of choice complexity only consider complexity introduced exogenously from the tasks respondents face. In the context of a stated conjoint survey, this article establishes endogenous complexity measures through decision-makers' experience known as the endowed bundle before the survey. Results show that complexity should not only be defined exogenously. Endogenous complexity measures are important in determining the utility associated with an alternative and the decision of whether to participate in the market. In addition, some of these complexity effects are nonlinear. We also show that exogenous complexity simultaneous affects the choice consistency. |
