Antecedents of true brand loyalty
No full textWe examine a model of six latent constructs and propose that true brand loyalty can be explained as a result of five distinct antecedents: brand credibility, affective brand conviction, cognitive brand conviction, attitude strength, and brand commitment. Data from experimental conditions with manipulations of eight product classes and two involvement levels lend support for the proposed model, demonstrating that brand loyalty can be considered as truly loyal only when mediated by a high degree of affective and cognitive brand conviction, and attitude strength. Advertising and marketing implications for the relationships among the six constructs under different manipulation conditions are discussed.
Choice models based on mixed discrete/continuous PDFs
No full textThis paper introduces a variant of random utility choice models based on mixed probability density functions, hence the adopted moniker “k-Mix models.” Mixed pdf’s contain components with the usual continuous density function specifications that underlie common choice models (e.g. MNL, GEV, MNP), but also contain one or more discrete probability mass points. These mixed pdf’s result in models that can be interpreted to reflect different regimes of decision-making. Two exemplars developed in this paper, the 2- and 3-Mix models, are the result of a mixed pdf that combines a continuous pdf, plus one or two mass points, respectively. The 2-Mix permits a specific alternative to be in the Tradeoff Condition (the usual situation for alternatives in extant choice models, and the only regime in which compensatory utility is defined and compared) or in the Rejection Condition (in which an alternative has extreme disutility). The 3-Mix model adds the Dominance Condition (in which an alternative has an extremely attractive utility) – interestingly, the inclusion of this condition makes the model capable of simulating a particular form of satisficing decision making. These models are derived, discussed and compared relative to several extant choice models, then applied empirically on both a RP data set (work trip mode choice) and a SP data set (recreation campsite selection).
Measuring and valuing quality of life for public health research : application of the ICECAP-O capability index in the Australian general population
No full textConclusions: The results provide insights into the assessment of capability in the Australian general population. The ICECAP-O shows promise for application in the measurement and valuation of quality of life in general population surveys, and incorporation into economic evaluations of public health interventions.
Whose values in health? : an empirical comparison of the application of adolescent and adult values for the CHU-9D and AQOL-6D in the Australian adolescent general population
No full textConclusion: The differences in adolescent and adult values for identical health states are more profound for the CHU-9D and ultimately may be significant enough to have an impact on health care policy. It is important to note that there are important differences between the CHU-9D instrument and the AQOL-6D instrument that may also have a significant impact on the valuations obtained.
Outcomes of social care for adults : developing a preference-weighted measure
No full textConclusions: Although further work is needed, particularly to develop an equivalent measure for informal carers and to explore the links with health QALYs, the measure has considerable potential. A number of methodological advances were achieved, including the first application of TTO in a social care context and use of BWS to establish service user preferences.
Identifying differences in willingness to pay due to dimensionality in stated choice experiments : a cross country analysis
No full textThis paper explores the influence of both cultural and socio-economic characteristics on the perception of complexity and cognitive load associated with stated choice (SC) experiments. Complexity is analysed in terms of five design dimensions which were systematically varied according to a macro experimental design. To study the influence of cross country differences on willingness to pay estimates, we combined datasets collected in Sydney, Santiago de Chile and Taichung city in Taiwan, all of them related to an equivalent route choice experiment. Several mixed logit models were specified and estimated; our results show that design dimensions do have an impact on the behavioural outputs of discrete choice models estimated on SC data. However, these influences seem to be data-specific, suggesting that the impact of design dimensions upon SC outcomes may be local and not necessarily transferable across different countries and cultures.
Utility of gambling under p(olynomial)-additive joint receipt and segregation or duplex decomposition
No full textThis article continues our exploration of the utility of gambling, but here under the assumption of a non-additive but p(olynomial)-additive representation of joint receipt. That assumption causes the utility of gambling term to have a multiplicative impact, rather than just an additive one, on what amounts to ordinary weighted utility. Assuming the two rational recursions known as branching and upper gamble decomposition, we investigate separately the rational property of segregation and the non-rational one of duplex decomposition. Under segregation, we show that each pair of disjoint events either exhibits weight complementarity or both support no utility of gambling, a property called UofG-singular. We develop representations for both cases. The former representation is a simple weighted utility with each term multiplied by a function of the event underlying that branch. The latter representation is an ordinary rank-dependent utility with Choquet weights but with no utility of gambling. Under duplex decomposition, we show that weights have the intuitively unacceptable property that there is essentially no dependence upon the events, making duplex decomposition, in this context, of little behavioral interest.
The role of environmental management in consumers preferences for corporate social responsibility
No full textConsumers in modern societies are increasingly sensitive to environmental performance by large and small corporations, making it a crucial issue in the overall policy of corporate social responsibility. The objective of this paper is to study the role of environmental performance in the profile of corporate social responsibility as perceived by consumers. We utilize a stated preference approach to the study of consumer’s preferences. This approach allows for the evaluation in monetary terms of the trade-offs that individuals can make between various aspects of corporate policy decisions, including the extent of environmental performance. The data is modelled by means of a mixture heuristics approach that allows us to study the utilization of various decision rules in the choice of products with various degrees of environmental performance. The results show that the linear compensatory heuristic is the most extended across individuals and these subjects value most the policies concerned with environmental management. Those subjects opting for the non-compensatory decision rule tend to focus on the attribute of good labour relations as the most salient factor defining corporate social responsibility. In addition, policy measures are relatively more valued for some products rather than for others, suggesting that consumers discriminate between products when valuing companies’ environmental profiles.
Toll product preferences and implications for alternative payment options and going cashless
No full textThere has been a great deal of research on deriving estimates of the value of travel time savings (VTTS) as a way of converting travel time benefits of toll roads relative to free routes into monetary units, the major user benefit in the development of forecasts of traffic and hence revenue streams. By contrast there has been almost no consideration given to identifying the role that various tollroad products play in establishing preferences for toll routes over non-tolled routes. Increasingly tollroads give users the option to pay by cash at a toll booth, by electronic tolling or by a pre- or post-paid debit and credit account system involving vehicle identification. The efficiency gained by electronic tolling for both the users and the operator have resulted in moves in many jurisdictions to eliminate cash collection entirely (or not introduce it when introducing a new tolled road facility), and to introduce a range of pre- and post-payment options. This has been accompanied by a growing move to distance-based charging in some contexts which is more cumbersome to structure with a cash option. This paper investigates current and potential travellers’ preferences for a range of toll products and how much individual’s are willing to pay for very specific toll products. Data from a stated choice experiment is used in a mixed logit model to establish the role that toll products play in the context of offered times and costs of alternative routes, in choosing between alternative ways of paying for the use of tolled routes.
Allowing for intra-respondent variations in coefficients estimated on repeated choice data
No full textPartly as a result of the increasing reliance on Stated Choice (SC) data, the vast majority of discrete choice modelling applications are now estimated on data containing multiple observations for each respondent. At the same time there has been growing interest in the representation of unexplained heterogeneity in choice data, using random coefficients models such as Mixed Multinomial Logit (MMNL). The presence of multiple observations for each respondent can indeed be a great asset in the identification of such variations in tastes. However, in this paper, we question the validity of the common assumption that tastes vary across respondents but stay constant across repeated choices for the same respondent. We extend the existing framework for the MMNL analysis of panel data by allowing for intra-respondent heterogeneity on top of inter-respondent heterogeneity. An empirical analysis making use of a SC dataset for route choice confirms our hypotheses and shows that superior performance is obtained by our more general model.
