Vaccines against several common foodborne pathogens are being developed and could substantially alter the policy tools available to address foodborne illness. However, little analysis is available to suggest how social welfare would be affected by these new vaccines. To address this void, we use...

Recreational anglers are known to seek different types of experiences in different settings.Such preference and behavioural diversity has important management implications. Researchmethods which assume only a limited degree of preference heterogeneity and impose rigidsubstitution patterns can...

The provision of nutrition and health information on food labels is increasing as an industry and regulation answer to the growing consumer concern with diet-health relationships. Prior research has shown that the presence of this information on food labels is valued by consumers; however there...

Heterogeneity in measurement model parameters across known groups can be modeled and tested using multigroup confirmatory factor analysis (CFA). When it is not reasonable to assume that parameters are homogeneous for all observations in a manifest group, mixture CFA models are appropriate....

Guttman (1947) developed a scaling method in which the items measuring an attribute can be ordered according to the strength of the attribute. The Guttman scaling model assumes that every member of the population belongs to a scale type and does not allow for response errors. The Proctor (1970)...

Fairness is necessary to successful evaluation, whether the context is simple and concrete or complex and abstract. Fair evaluation must begin with careful data collection, with clear operationalization of variables whose relationship(s) will represent the outcome(s) of interest. In particular,...

There is a growing body of evidence in the non-market valuation literaturesuggesting that responses to a sequence of discrete choice questions tend to violate theassumptions typically made by analysts regarding independence of responses andstability of preferences. Heuristics such as value...

The aim of this paper is to report new evidence relating to residents’ valuations of aircraft noise in three countries with an emphasis on a comparison of the valuations obtained using two contrasting approaches. One might be regarded as a standard stated choice approach offering pairwise...

In models with unobserved taste heterogeneity, distributional assumptions can be placed in two ways: (1) by specifying the distribution of coefficients in the utility function and deriving the distribution of willingness to pay (wtp), or (2) by specifying the distribution of wtp and deriving the...
