“…Moreover, the choice sets were always presented in the same order, which might also affect the outcome of the DCE. In this regard, evidence shows that preference may change when the choice sets are presented in a different order [64][65][66]. We encourage future similar research to randomize the choice sets presented to the respondents.…”

For health, environmental, and animal welfare reasons, an increase in the consumption of meat in our diet is of great concern in today’s society. Meat substitutes have been advocated for a long time as a solution to these problems and are evolving continuously with technological advancements. Despite these efforts, it is remarkable that meat alternatives only account for a small portion of the global meat market. As a result, we examined the factors that affect Flemish consumers’ preferences for meat substitutes in Belgium using a discrete choice experiment. We also examined consumers’ preferences after providing additional information, as well as the impact of color-coding certain attribute levels on their preferences. The study was conducted using a sample size of 162 participants selected via convenience sampling. The findings show that it is important to keep the sensory properties of meat substitutes similar to those of actual meat. The results also indicate that additional information regarding the environmental and health impact of meat consumption can help to promote meat substitutes. The traffic light color coding of the levels of saturated fat and ecofootprint attributes increases the preference for healthy and environmentally friendly alternatives. Finally, we observed that individual-level variations in the utility attributed to meat substitutes are explained significantly by age, gender, education, current diet group, and attitudinal factors. Overall, we can conclude that the promotion of meat substitutes can be achieved via a combined strategy that focuses on improving the taste, appearance, and nutritional profile of meat substitutes, as well as raising consumers’ awareness of the environmental and health impact of meat consumption.

“…The SP-ordered categorical questions were always presented first, and this may have led to the lower completion rate for the DCE tasks for males. Nonrandomized ordering of choice tasks may lead to strategic behavior 34 and therefore may bias the MRS estimates. However, there was no evidence of strategic or nontrading behavior across the survey formats for either gender.…”

A Comparison of Ordered Categorical versus Discrete Choices within a Stated Preference Survey of Whole-Blood Donors

et al. 2022

There are different stated preference (SP) approaches, including discrete choice experiments (DCEs). DCEs are a popular SP approach, but in some settings, alternative ways of framing survey questions may be more appropriate. The Health Economic Modelling Of Alternative Blood Donation Strategies (HEMO) study required choice tasks to be framed so that the study could estimate the effect of attribute levels on the frequency of a behavior—in this case, blood donation. SP questions were formulated to require ordered categorical responses from a single profile of attribute levels. However, it is unknown whether this way of framing SP questions leads to estimates of marginal rates of substitution (MRS) that are different from traditional DCE choices between 2 alternative profiles. The aim of this article is to compare estimates of relative preferences from SP questions requiring ordered categorical versus discrete choice responses. We compared relative preferences elicited from the 2 approaches for a common set of attributes and levels, formulated as choice tasks for 8,933 whole-blood donors. We found that the 2 forms of survey questions provided similar MRSs estimates. For example, respondents were willing to trade off only a small increase in travel time to receive a health report, irrespective of whether the choice given was binary (DCE response; approximately 3 min) or from an ordered category (about 8 min). The finding that any differences in the estimated MRSs are not of substantive importance offers some reassurance for policy makers in that estimates of relative preference may be robust to alternative ways of framing the survey questions. These findings can encourage future studies to frame choice tasks that align with the study’s objective. Highlights This article compares the relative preferences from stated preference (SP) questions requiring ordered categorical versus discrete choice responses. The approaches were contrasted for blood donation service characteristics that offer opportunities to donate blood. The estimates of relative preferences for alternative blood donation service characteristics were similar between the 2 forms of SP approach. This study illustrates how SP survey questions can be formulated to provide responses on an ordered categorical scale and to estimate marginal rates of substitution between different attributes, which can be compared with those derived from discrete choice experiment (DCE) choices. The article highlights the potential value of considering alternative choice framings rather than relying solely on DCEs.

“…For instance, some respondents may consider the risk of free riding (by others as well) if the measure described were to be implemented, thus perceiving the survey as inconsequential and unlikely to produce results. Moreover, some respondents strategically respond in hypothetical surveys, allowing them to adjust their future decisions and outcomes to their benefit, should they materialise (Nguyen et al 2021). Studies of recreational goods (Xu & He 2022) have compared various forms of recreation user fees and payments to determine their efficacy.…”

The objective of the study is to test whether the subsidy reduction of daily consumer goods as a payment vehicle can influence individuals' willingness to pay (WTP) for environmental and nature conservation. Specifically, it assessed the impact of price sensitivity on the willingness to conserve wetlands, using the subsidy reduction approach. Malaysia's Setiu Wetland (SW) served as a case study to gauge respondents' preferences to trade-off the benefits of subsidy with conservation of natural resources. The welfare economic concept of WTP was applied to estimate the economic value of SW with the application of choice experiment method. Analysis using the Random Parameter Logit model showed that respondent's WTP for conserving SW, through subsidies reduction, amount to RM120.59 annually. The price sensitivity in the model is high, suggesting that respondents are greatly concerned about the monetary attribute. This further implies that subsidy reduction can be a most consequential and coercive payment for Stated Preference studies. Thorough assessment of the payment structure is crucial for the quality of environmental value research in developing economies when conventional methods may not be ideal. It is recommended that policymakers consider other alternatives as payment vehicles for environmental conservation to ensure broader support for conservation initiatives.
