“…Priors were obtained from a multinomial logit model based on quantitative pilot study with 17 responding patients each answering ten choice tasks, and through qualitative work including interviews with HCPs. For full details, see Kloejgaard, M.;Bech, M.;Soegaard, R. (2012). The final design contained 18 choice scenarios.…”

A growing number of studies across different fields is making use of a new class of choice models, labelled variably as hybrid model structures or integrated choice and latent variable models, in incorporating the role of attitudes in decision making. To date, this technique has not been used in health economics. The present paper looks at the formation of such attitudes and their role in patients' treatment choices in the context of low back pain. We use data stated choice data collected from a sample of just under 300 respondents referred to a regional spine centre in Denmark. We show how the hybrid model structure is able to make a link between attitudinal questions and treatment choices, and also explains the variation of these attitudes across key socio-demographic groups. However, we also show how, despite their growing popularity, the key findings of the model, net of a greater insight into the drivers of attitudes and small gains in efficiency, are no different from standard approaches which remain much easier to apply. In the present application, we also show how only a small share of the heterogeneity can be linked to the attitudinal construct.

“…However, all the attributes to compile may not necessarily be policy relevant. Thus, to ensure that attributes are policy relevant and at the same time preferred by respondents, interview feedbacks are required (Hanley et al, 2001;Kløjgaard et al, 2012).…”

Are Malaysians eager to use their cars less? Forecasting mode choice behaviors under new policies

a b s t r a c tIn Malaysia, transportation accounts for almost 70% of carbon monoxide emissions. This study sought to discover whether intelligently changing policies for the private and public transport sectors can affect mode choice of private car owners in the Klang Valley, Malaysia. Results of a random parameter logit model identified the most significant parameters affecting respondents' utility measures. These were introducing a congestion fee in private transport mode; and also access, comfort and the frequency of the available public transport. Respondents' marginal value estimates showed that they are willing to pay up to 175% of their hourly wage to have a more frequent and more accessible public transport. Moreover, the value of travel time showed that persons with longer commute time by car and bus are willing to pay more to save travel time. This is estimated about 25-50% of hourly wage of respondents. Simulation of results indicate that introducing the congestion fee has the largest impact both in modal shift and in reducing the number of cars used in the Klang Valley area. Overall results of this study suggested that any government intervention through innovative transport policy implementation such as pricing and providing more efficient public transport could result in 70% modal shift among current car users to public transport.

Abstract:In an effort to support the long-term viability of the bioenergy industry through an end market for digestate, we investigated purchasing preferences for fertilizer product features in the home gardening market. We conducted a discrete choice experiment (DCE), presenting 504 respondents with a total of 6048 product attribute choices in a simulated context that replicated the tradeoff decisions made in the real marketplace. We analyzed the choice data using a hierarchical Bayes estimate to generate part-worth utilities for fertilizer product attributes. We then conducted a latent class analysis to identify market segments that could be expected to respond to differentiated product design strategies. We were able to quantify both purchasing preferences for fertilizer product attributes as well as the importance of each attribute to the perceived utility of a product. We were further able to identify five distinct market segments that make clear the potential for differentiated strategies in the home gardening market. We found both negative and positive price sensitivities, with sociodemographically distinct subgroups that favored low-, mid-, and high-priced products. We also found purchasing preferences for brand status, product labeling and nutrient values. Our results provide insights that should help product managers in the biogas industry develop marketing strategies to integrate digestate into a sustainable energy production system.
