| 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. |

| Locavorism and the Local Food Movement have captured attention of consumers, production suppliers and academic researchers. Local food advocates emphasize the benefits of locally grown food from fresher to better tastes and to more energy efficient due to shorter transportation distance. However, limited studies have been done about household grocery purchase allocations in the awakening of local food, especially for individuals who stick with the “locavore” principle. Through a recent survey conducted in Ohio, this study found that mainstream food suppliers (national grocery chains or retailers) still claim most market shares, however, locally owned food stores and farmers’ markets are gaining popularity. The study also found that education attainment... |

| A growing share of water pollution in the U.S. can be attributed to nonpoint sources (USEPA 2002). Some of this trend can be attributed to declining point source (PS) emissions as a result of regulation under the Clean Water Act (CWA). However, fertilizer-intensive practices used to improve agricultural productivity over recent decades have also increased nitrate loads and resulted in water quality impairments. Nonpoint source (NPS) pollution from agricultural practices is generally exempt from federal regulation. However, some voluntary programs allow point sources subject to the CWA’s effluent limitations to meet their standards by purchasing offset credits reflecting reductions in NPS discharges to the same waters (USEPA 2004). Such water quality... |

| Much of Hawaii’s economy relies on its unique marine environments, which are threatened by degradation from stormwater runoff. Using a stated preference method of choice-based conjoint (CBC) analysis, based on stylized photographs, this study examines both residents’ and visitors’ marginal value for levels of attributes associated with Hawaiian beach recreation. Each attribute (sand quality, water quality, congestion and water safety conditions) was significant for both residents and tourists, with water quality being the single most important attribute. There is little distinction between resident and tourist marginal value, except for a greater value lost for below average water quality among tourists. |

| A conjoint analysis of equestrian trail characteristics (trail length, scenic views, open land, bathroom/shower facilities, restricted use, distance, and entrance fee) is conducted for the state of Kentucky. The conditional logit results show location is an important determiner of willingness to pay. In particular, scenic views and restricted use are highly valued (WTP above $20). However, increased distance from home to the trail results in a negative willingness to pay. |

| 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... |

| 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. |

| 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... |
