Societal preferences for fertility treatment in Australia: a stated preference discrete choice experiment

Objective: To investigate preferences for fertility treatment from the Australian general population with the aims of calculating the willingness to pay in tax contribution for attributes (characteristics) that make up treatment and for an “ideal” fertility treatment program. We also assessed whether willingness-to-pay varies by the relationship status or sexual orientation of the patient.

Methods: A stated preference discrete choice experiment was administered to a panel of 801 individuals representative of the Australian general population. Seven attributes of fertility treatment under three broad categories were included: outcome, process, and cost. Attributes were identified through published literature, focus group discussions, expert knowledge, and a pilot study. A Bayesian fractional experimental design was used, and data analysis was performed using a generalized multinomial logit model. Further analyses included interaction terms and latent class modeling.

Results: Six of the seven attributes influenced the choice of a treatment program. Under process attributes, individuals preferred: continuity of care of clinic staff, where patients are seen by the same doctor but different nurses at each visit; “alternative” treatments being offered to all patients; and onsite clinic counseling and peer-support groups. Personalization and tailoring of the treatment journey were not important. Among outcome attributes, the improved success rate of having a baby per cycle and significant side-effects were considered important. Cost of treatment also influenced the choice of treatment program. Individual preferences for fertility treatment were not associated with patients’ relationship status or sexual orientation. Latent class modeling revealed sub-groups with distinct fertility treatment preferences.

Conclusion: This study provides important insights into the attributes that influence the preferences of fertility treatment in Australia. It also estimates socially-inclusive willingness-to-pay values in tax contributions for an “ideal” package of treatment. The results can inform economic evaluations of fertility treatment programs.     

If only consumers knew: How sampling impacts wine innovation diffusion in the U.S. foodservice industry

A survey (n = 151) explored consumers’ experiences with wine-on-tap, a current trend in the U.S. foodservice industry. Wine consumers’ innovativeness (R² = .49) was explained by wine involvement, opinion leadership, and usage of information sources. Those who recently tried wine-on-tap (n = 43) were significantly more innovative (innovators) than those who never tried it (noninnovators). Furthermore, noninnovators expected to pay significantly less for a glass of wine-on-tap when compared with wine poured from a bottle. Contrary to expectations, the driving force for noninnovative behavior is lack of availability and awareness as opposed to a lack of interest in wine-on-tap.     

Stated Willingness-to-Pay for Organic Fruit and Pesticide Ban

Abstract

Income growth in highly industrialised countries has resulted in consumer choice of foodstuffs no longer being primarily influenced by basic factors such as price and organoleptic features. From this perspective, the present study sets out to evaluate how and to what extent consumer choice is influenced by the possible negative effects on health and environment caused by the consumption of fruit containing deposits of pesticides and chemical products.

The study describes the results of a survey which explores and estimates consumer willingness to pay in two forms: a yearly contribution for the abolition of the use of pesticides on fruit, and a premium price for organically grown apples guaranteed by a certified label. The same questionnaire was administered to two samples. The first was a conventional face-to-face survey of customers of large retail outlets located around Bologna (Italy); the second was an Internet sample. The discrete choice data were analysed by means of probit and tobit models to estimate the utility consumers attribute to organically grown fruit and to a pesticide ban. The research also addresses questions of validity and representativeness as a fundamental problem in web-based surveys.     

Utilizing environmental information and pricing strategies to reduce externalities of tourism: the case of invasive species in the Galapagos

The increase in demand for nature-based tourism brings economic and educational benefits but risks the introduction of invasive species. Increasing the length of tourist trips can better balance these benefits and risks by maintaining revenues while reducing the number of unique contacts with tourists. Changing the relative prices of trips can induce tourists to take longer trips. We hypothesized that providing information about the negative externalities of tourism could improve the effectiveness of such pricing strategies.

We administered one of two discrete choice surveys to tourists considering a trip to the Galapagos. One of the surveys described the Galapagos as a fragile ecosystem susceptible to invasive species; the second described it as a standard nature-based destination. For each sample, we estimated the probability of the tourist choosing a short versus long trip, given the tourist's personal information and trip options presented to him. We then simulated the demand for trips using three pricing strategies. We found that providing information on invasive species significantly increased the efficacy of strategic pricing. We propose using a two-prong approach to tourism management: educate potential tourists about the islands’ vulnerabilities, and simultaneously increase the per-day cost of short trips relative to that of longer trips.     

Do What Consumers Say Matter? The Misalignment of Preferences with Unconstrained Ethical Intentions

Nearly all studies of consumers’ willingness to engage in ethical or socially responsible purchasing behavior is based on unconstrained survey response methods. In the present article we ask the question of how well does asking consumers the extent to which they care about a specific social or ethical issue relate to how they would behave in a more constrained environment where there is no socially acceptable response. The results of a comparison between traditional survey questions of “intention to purchase” and estimates of individuals willingness-to-pay for social attributes in products reveal that simple survey questions are too “noisy” to provide operationally meaningful information and overstate intentions to a considerable extent.

Ambiguity of measured WTP for quality improvements when quantity is unconstrained: a note

This paper addresses the issue of how to estimate by contingentvaluation methods the maximum price consumers are willing topay when a new quality is available for a market good for whichquantity adjustments are possible. We argue that current practice,which typically does not specify a quantity when asking consumersthe price they are willing to pay for a new quality product,fails to identify prospective consumers' behaviour when theyare free to adjust the quantity purchased. Theoretical modelsare discussed for assessing the maximum price consumers arewilling to pay in these cases, and econometric approaches toaddress these situations are discussed.     

Valuation of nature-based tourism resources using dichotomous choice contingent valuation method

The purpose of this paper is to measure the potential revenue from nature-based tourism resources in the environmentally sensitive area of Mt Minju, South Korea. A dichotomous choice contingent valuation method was employed to estimate the mean willingness-to-pay, contingent on a hypothetical market scenario. The empirical results show that the economic value of nature-based tourism resources was estimated at 5905 Won (ca US$ 7) per visitor. This implies that the significant economic value of natural resources will be lost from any large-scale development by degrading natural environments. In addition to the value of natural resources, nature-based tourism also provides the locally owned small tourist businesses with lower leakages than the externally owned large-scale ones. Low leakage implies that local residents gain more direct income from nature-based tourism.     

Interaction Effects among Labeled Attributes for Eggs in the United States

New labels for food products continue to be introduced in the United States. This paper estimates interaction effects among labeled attributes for eggs to investigate cases where affixing labels of “premium” attributes would indeed gain additional premiums in the U.S. market. A latent class analysis identified four consumer segments (Attribute Seekers, Price Checkers, Local Supporters, and Combination Responders). Several interaction effects were sufficiently large in magnitude to neutralize the main effects, but differently for each segment. While the combination of certified-organic with cage-free or local label yielded negative premiums in certain segments, the premium Attribute Seekers were willing to pay were considerable. Across all segments, preferences for locally produced products were robust singly or in combinations. Consideration of interaction effects and consumer segments are recommended for effective labeling strategies.     

Preferences for tourist information centres in the ubiquitous information environment

The rapid development of information communication technology has encouraged tourism authorities to carefully consider the typical duties of tourist information centres (TICs), wherein visitors acquire various kinds of travel information about a particular destination. This study aims to provide useful management implications to help tourism organisations develop feasible TIC operational strategies and implement alternative services in the ubiquitous information environment. To provide a richer understanding of tourists' heterogeneous preferences for TICs, this study makes use of the stated preference choice method with a sample of South Korean domestic tourists. Despite the widespread use of personal mobile devices, our study results suggest that South Korean domestic tourists still prefer to visit various types of TICs to acquire travel information. Results indicate that the TIC visitor group is less sensitive than the non-visitor group to advanced information communication technology and more satisfied with the availability of WIFI signals to facilitate the use of personal mobile devices or laptops. Our respondents also demonstrate their preferences for some TICs constructed with container structures, whereas they showed a strong aversion to visiting booth-styled TICs inside larger buildings. Based on these findings, this study provides several management strategies to fulfil tourists' ever-changing needs.     

The Survey of Heterogeneity on Organic Products Consumers’ Preferences Using Mixed Logit and Latent Class Models

Abstract

Today, the importance of consumption of organic products has become more evident to the consumer due to the great benefits of these products. The aim of this study is to investigate the factors affecting the preferences of organic tea consumers in Tehran by considering the heterogeneity of consumer’s preferences. For this purpose, mixed logit and latent class model were used. The required information were collected through field surveys by completing a questionnaire from 405 respondents from Tehran citizens in 2016. Results from estimating mixed logit and latent class models confirm the heterogeneity of preferences between consumers. Different levels of income, education, age, history of poisoning and awareness of organic products were identified as heterogeneous factors. The results of the estimation models showed the maximum willingness-to-pay is related to the attribute of the disease and long-term effects. According to the findings of the study, it is suggested to help increase people's awareness of the characteristics of organic products and the use of targeted-oriented strategies to encourage consumers to consume organic products.
