Abstract:

A growing body of literature demonstrates that many behavioral anomalies observed in stated-preference elicitation methods such as the contingent valuation method are also observed in actual choices and vice versa. This presentation furthers the argument that such parallel behaviors should be viewed as a strength of stated-preference methods. Three well-known anomalies observed in both stated preferences and actual choices are first reviewed to lay the foundation for this argument. A number of lesser-known anomalies are then presented to demonstrate the wider prevalence of parallel anomalies in stated preferences and actual choices.

Abstract:

Purpose This paper aims to understand the motivations behind married men preferring sons and to quantify the association between a couple’s stated son preferences. Son preference is an endemic problem in India. With half a million female foetuses aborted each year, the root causes of son preference in India have been widely studied. Little is known, however, on how couples mutually decide on their desired child sex-ratio. Design/methodology/approach Using data from the third National Family and Health Survey, the authors apply three-stage least square and optimal general method of moment methods to demonstrate association. Robustness checks are performed on plausibly exogenous instrumental variables and selection issues in the marriage market. Findings The authors show that their spouse's son preference is by far the most significant factor associated with a person's own stated son preference. The association between spouse's stated son preference is observed only for couples being married for three to five years. It is postulated that this is the critical period when sex-selective abortion decisions are being made. Originality/value The focus of existing empirical studies is nearly always on the mother's son preference only. The hypothesis is that spouses mutually influence each other’s preferences and models estimating determinants of son preference should include preferences of both spouses. To the best of the authors’ knowledge, this is the first attempt to understand the motivations of married men towards preferring sons and quantify the association between spouse's stated son preference and respondent's stated son preference.

Abstract:

Governments sometimes use committees of selected volunteers to provide comment on environmental policy choices. We use a repeated choice experiment to explore how a deliberative citizen jury (DCJ) treatment affects the conservation preferences of DCJ participants who engage in a budget allocation exercise. First round choice experiment participants were invited to volunteer for one of a pair of paid DCJ sessions. Stated preference results for the DCJ participants were compared with a pseudo-control formed by matching non-participants on socioeconomic characteristics. Both preference and response heterogeneity declines for the DCJ treatment group, relative to the control. The stated preference results for the DCJ group are significantly different from those for the total sample, and the DCJ budget allocation results are inconsistent with the preferences expressed by the total sample. DCJ style committees may reflect how educated citizens make choices. However, selection and impacts of the deliberation make it likely these committees are not representative of the broader population.

Abstract:

Purpose The popularity of wealth management in Taiwan has unleashed tense competition among financial advisors. Consumers are now more conscious of their financial services purchasing behavior. This paper aims to provide insights into local-specific investors’ characteristics and consumers’ financial product preferences and to introduce a different concept to identify localization-suitable products. Design/methodology/approach To understand customers’ preferred products, the paper examines consumers’ financial behavior by analyzing preference characteristics using data collected from Taiwanese investors. The study entailed a questionnaire designed for consumers using the stated preferences method and the multinomial and nested logit models to develop preference models for consumers’ financial products. A statistical test using the t-value, likelihood and ρ2 to observe investor preference product reactions was also used. Findings The study finds that investors are sensitive to the rate of return on investments and performance changes in foreign currency, stock and mutual funds. An elasticity analysis and prediction of the market share among interactive products show that stock and mutual funds are strongly related and the rate of return on stock undoubtedly influences the market. Originality/value The stated preference method and inclusion of risk appetite improve our understanding of consumer choice and investors’ financial product preferences and characteristics. The results provide suitable localization product suggestions for financial institutions to help them understand their customers’ behaviors better. This paper’s results are also useful in the context of smart financial services such as financial robot technology.

Abstract:

The concept of residential housing preferences has been studied across multiple disciplines, with extensive literature supporting both stated and revealed preference methods. This study argues that both preference types, stated and revealed, should be assessed concurrently to achieve a more comprehensive understanding of residential housing choices. To provide evidence, this research used findings from a public participation GIS survey that identified the stated housing preferences associated with three categories of urban residents, which were called urban “tribes”. We implemented an analytical framework using fuzzy modelling to relate stated preferences with revealed preferences for the same individuals using empirical data describing the urban structure in Tampere, Finland. Following an analysis of the relationships between residents’ revealed preferences and urban structural variables, we examined the consistency of stated housing preferences with revealed preferences. The results show considerable mismatch between the stated and revealed preferences for the urban tribes that were examined i.e., the preferred housing environment was significantly different from the actual living environment. Further, the stated preferences showed disequilibrium within the current structure of the housing supply in Tampere. The findings can have important implications for housing policy making in Tampere. Further, the use of a novel fuzzy model approach demonstrated a flexible and tolerant method for working with imprecise and variable social data to capture subtle differences. Finally, this study elaborately discusses the remaining limitations and suggests how they should be addressed in future research.

Abstract:

The Orbit demand model allows the magnitude of the calibration to stated purchase intentions to vary based on the magnitude of the stated quantities. Using an empirical example of stated trips, we find that the extent of calibration varies substantially with less correction needed at small stated trips (-25%) but larger corrections at higher quantities of stated visits (-48%). We extend the Orbit model to calculate consumer surplus per stated trip of $26. Combining the calibrations in stated trips and value per trip, the Orbit model provides estimates of annual benefits from 60% to 111% less than the count data model.

Abstract:

We present a systematic method for generating activity-driven, multi-day alternative activity patterns that form choice sets for stated preference surveys. An activity pattern consists of information about an individual’s activity agenda, travel modes between activity episodes, and the location and duration of each episode. The proposed method adjusts an individual’s observed activity pattern using a hill-climbing algorithm, an iterative algorithm that finds local optima, to search for the best response to hypothetical system changes. The multi-day approach allows for flexibility to reschedule activities on different days and thus presents a more complete view of demand for activity participation, as these demands are rarely confined to a single day in reality. As a proof-of-concept, we apply the method to a multi-day activity-travel survey in Singapore and consider the hypothetical implementation of an on-demand autonomous vehicles service. The demonstration shows promising results, with the algorithm exhibiting overall desirable behavior with reasonable responses. In addition to representing the individual’s direct response, the use of observed patterns also reveals the propagation of impacts, that is, indirect effects, across the multi-day activity pattern.

Abstract:

10 Background: Incorporating patient preferences into CRC screening decisions has been identified as one method for improving informed decision making and increasing screening adherence, yet the impact of tailoring screening recommendations to patients’ preferences on these outcomes has not been evaluated. Methods: We compared the effect of a web-based preference-tailored decision tool (intervention) to a standard information decision tool (control) through an RCT at two VA sites. Eligible subjects were age 50-77, due for CRC screening, with a scheduled primary care visit. Participants arrived 45 minutes early to complete consent and were randomized online. Telephone surveys were conducted 3-5 days post-enrollment and CRC screening adherence was collected from medical charts 6 months later. We evaluated the effect of the tool on adherence and compared stated test preferences to test recevived through Chi-square tests and regression. Results: 468 subjects were enrolled from two VAs. CRC screening adherence 6-months post-enrollment was 38.6% and was not significantly different between groups (37.4% intervention, 39.7% control). Most were adherent with fecal occult blood test (FOBT) (22.4%), followed by colonoscopy (COL) (16.7%). The most commonly recommended test by physicians was COL (59.2% of tests recommended), though veterans most commonly stated a preference for FOBT (60.1%). The features of tests most important to veterans were nature of the test (32.8%), effectiveness (27.1%), and risk of complications (17%). Participants significantly more often adhered to the test that they stated they preferred after the intervention than with a non-preferred test (30.4% adhered to preferred test vs. 7.6% adhered to non-preferred test, P<0.001). Conclusions: CRC screening adherence in this population of veterans was low and the preference-tailored intervention did not significantly improve adherence relative to standard information. Veterans preferred a non-invasive test (FOBT) despite higher rates of recommendation for COL by their physicians. Improving concordance between physician recommendations and patients’ preference may be one method for improving CRC screening adherence in this population.

Abstract:

Pedestrian’s street-crossing behaviour has a significant effect on traffic performance and safety. The crossing behaviour is determined by human factors and environmental factors. Aiming at examining the pedestrian perceptions toward crossing facilities and preferences for crossing locations, an observational study of pedestrian crossing behaviour at urban street is conducted. The perceptions and preferences of pedestrians are collected using stated preference technique. A specific questionnaire is designed to conduct the stated preference survey. A multinomial logit model is proposed to describe the perceptions and preferences of pedestrians on crossing facilities and locations. The sensitivity analysis is performed to discuss the influence of various factors on crossing behaviour. Then the relationship between crossing locations and crossing distances is analyzed by a new proposed method. With the theoretical analysis, the engineering solutions considering pedestrian behaviour are suggested. The results are helpful to design human-centered crossing facilities in urban traffic.

Abstract:

Penelitian ini bertujuan untuk menganalisa kompetisi moda angkutan umum darat antarkota di negara berkembang seperti Malaysia, terkait atribut travel time dan travel cost. Kajian ini menjadi penting karena kebijakan infrastuktur di negara berkembang seperti realisasi double tracking project ETS di Malaysia, berpotensi menimbulkan persaingan moda khususnya bus dan kereta api, terkait dua atribut tersebut. Pendekatan analisis dilakukan menggunakan reveal preference method yang dipertajam dengan stated preference method. Tingginya kompetisi moda angkutan umum darat antarkota ini memungkinkan terjadinya mode shift, yang dapat diprediksi melalui preferensi dan persepsi pengguna moda. Preferensi dan persepsi pengguna moda bus antarkota dideskripsikan dengan memunculkan analisis sensitivitas terhadap 12.000 data set. Melalui analisis sensitivitas, dijumpai adanya perbedaan persepsi pengguna bus terhadap kebijakan penyedia jasa dalam perubahan nilai utilitas kedua moda tersebut. Temuan studi ini menarik, dimana reduksi travel time dan penurunan travel cost yang sama pada kedua moda, belum tentu menghasilkan persentase mode shift yang sama. Pengguna bus terlihat kurang begitu responsif terhadap pengurangan travel time maupun travel cost moda saingannya. Sebaliknya, pengguna bus antarkota lebih khawatir terhadap bertambahnya travel cost dan travel time moda mereka (bus). Diharapkan kajian ini menjadi pertimbangan bagi pembuat kebijakan agar pembangunan infrastruktur lebih tepat sasaran menuju terciptanya balance mode share. Terutama bagi kebijakan yang menimbulkan persaingan angkutan umum darat antarkota di masa depan.Kata kunci : Metoda stated preference, Reveal preference, Preferensi moda bus antarkota, Analisis sensitivitas.

Abstract:

The decline of soil fertility is a major constraint which results in lower levels of crop productivity, agricultural development and food security in Sub-Saharan Africa. This study is the first to perform a focalized investigation on the most interesting technological profiles to offer to each category of producers in Benin agricultural development hubs (ADHs) using the stated preference method, more precisely, the improved choice experiment method. The investigation focused on 1047 sampled plots from 962 randomly selected producers in villages of the Smallholder Agricultural Productivity Enhancement Program in Sub-Saharan Africa of the ADHs. An analysis of the experimental choice data with the endogenous attribute attendance and the latent class models was carried out to account for the attribute non-attendance phenomenon and the heterogeneity of the producers’ preferences. However, three classes of producer with different socio-economic, demographic, and soil physicochemical characteristics were identified. Thus, the heterogeneity of preferences was correlated with the attributes linked to the cost, sustainability, and frequency of plot maintenance. All producers, regardless of the ADHs, had a strong attachment to accessibility of technologies with short time restoration of soil fertility, and the ability to obtain additional benefits. These latest attributes, added to that relating to cost, tended to have a low probability of rejection in the decision-making process. These results have implications for local decision-makers facing the complex problem of resolving land degradation and local economic development challenges. The generalizability of these findings provides useful insight and direction for future studies in Sub-Saharan Africa.

Abstract:

This study extends the joint estimation of revealed and stated preference data literature by accounting for truncation in the revealed preference data. The analytical model and estimation procedure are used to estimate the value of recreational red snapper fishing in the Gulf of Mexico. This recreational red snapper valuation is decomposed into its direct and indirect components. As expected, the value of recreational red snapper fishing using the joint revealed-stated preference model proposed in this analysis is bracketed on the upper limit by the value obtained using the contingent valuation method and on the lower limit by the travel cost method. The results also indicate that the joint model improves the precision of estimated recreational red snapper valuation.

Abstract:

The purpose of this exploratory study was to determine whether learning preferences of secondary students identified with concomitant learning disabilities (LD) and emotional disturbance (ED) align with the instructional method with which they best learned mathematics. Responses to a preference survey given before and after instruction were compared with learning outcomes in a single-subject, alternating treatments research design investigating the effects of direct teach, computer-assisted instruction (CAI), and a combination of both methods. Results showed that most students were able to predict, by choice or stated preference, conditions under which they will learn best and, in hindsight, indicate the condition that provided the best learning outcome. This small study contributes to the literature on secondary mathematics learning for students with LD, and makes unique contributions regarding (a) the learning of students with comorbid LD and ED and (b) implementation of instruction that combines direct teach with CAI.

Abstract:

We update the joint estimation of revealed and stated preference data of previously published research to allow for joint estimation of the Travel Cost Method (TCM) portion using count data models. The TCM estimation also corrects for truncation and endogenous stratification as well as overdispersion. The joint estimation allows for testing consistency of behavior between revealed and stated preference data rather than imposing it. We find little gain in estimation efficiency, but our joint estimation might make a significant improvement in estimation efficiency when the contingent valuation scenarios involve major changes in site quality not reflected in the TCM data.

Abstract:

Global biodiversity loss and its consequences for human welfare and sustainable development have become major concerns. Economists have, therefore, given increasing attention to the policy issues involved in the management of genetic resources. To do so, they often apply empirical methods developed in behavioral and experimental economics to estimate economic values placed on genetic resources. This trend away from almost exclusive dependence on axiomatic methods is welcomed. However, major valuation methods used in behavioral economics raise new scientific challenges. Possibly the most important of these include deficiencies in the knowledge of the public (and researchers) about genetic resources, implications for the formation of values of supplying information to focal individuals, and limits to rationality. These issues are explored for stated-preference techniques of valuation (e.g., contingent valuation) as well as revealed preference techniques, especially the travel cost method. They are illustrated by Australian and Asian examples. Taking into account behavioral and psychological models and empirical evidence, particular attention is given to how elicitation of preferences, and supply of information to individuals, influences their preferences about biodiversity. Policy consequences are outlined.

Abstract:

Purpose – The purpose of this paper is to explore farmer acceptance of a biofortified staple food crop in a developing country prior to its commercialization. The paper focuses on the hypothetical introduction of a high-iron pearl millet variety in Maharashtra, India, where pearl millet is among the most important staple crops. Design/methodology/approach – A choice experiment is used to investigate farmer preferences for and trade-offs among various production and consumption attributes of pearl millet. The key pearl millet attributes studied include days it takes pearl millet to mature, color of the roti (flat bread) the grain produces, the presence of high-iron content (nutritional attribute), and the price of the pearl millet seed. Choice data come from 630 pearl millet-producing households from three purposefully selected districts of Maharashtra. A latent class model is used to investigate the heterogeneity in farmers’ preferences for pearl millet attributes and to profile farmers who are more or less likely to choose high-iron varieties of pearl millet. Findings – The results reveal that there are three distinct segments in the sample, and there is significant heterogeneity in farmer preferences across these segments. High-iron pearl millet is valued the most by larger households that produce mainly for household consumption and currently have lower quality diets. Households that mainly produce for market sales, on the other hand, derive lower benefits from consumption characteristics such as color and nutrition. Research limitations/implications – The main limitation of the study is that it uses a stated preference choice experiment method, which suffers from hypothetical bias. At the time of implementing this study biofortified high-iron pearl millet varieties were not yet developed, therefore the authors could not have implemented revealed preference elicitation methods with real products and payment. Originality/value – The method used (stated preference choice experiment method) is commonly used to value non-market goods such as environmental goods and products that are not yet in the market. It’s application to agriculture and in developing countries is increasing. As far as the authors know this is the first choice experiment implemented to investigate farmer/consumer preferences for biofortified crops. The study presents valuable information for development and delivery of biofortified crops for reducing micronutrient deficiencies.

Abstract:

Abstract The aim of this study was to analyze the modal shift of passengers by analyzing their preferences. If the preferences of passengers are known it is possible to build up mathematically their utility function. This is the statistically correct way to simulate the modal shift of the investigated area. To capture the preferences of passengers stated preference method was used in online questionnaire. Five key factors were identified (from the point of passengers): travel cost, travel time, comfort, safety and environmental efficiency. In order to decrease the number of questions three levels were predefined these three questions made the base of the choice model. Every replier got three alternatives and they were told to choose the best for themselves. From the results of the questionnaire the formulas and the parameters of the mode choice utility function was derived. With the help of statistical sample an exponential utility function showed the best matching. For the validation process a probability model was set up to be compared to the proportions of the utilities. With this utility function it is possible to handle the changes in possible future transport services. Based on the introduced statistical approach the described method can be used to identify the effect of transport modes on regional development and tourism. The revealed utility function can help to develop proper regional development plans.

Abstract:

This paper reports on a combined stated preference (SP) and revealed preference (RP) model for studying the effect of telecommuting on households’ residential location decisions. Logit models were developed to estimate the parameters of the utility function. The required data for the model estimation were collected in an attitudinal survey of employees of selected private and public organizations in the Ottawa–Carleton region. The RP information included respondents’ residential, employment, and socioeconomic characteristics. To obtain the SP responses, the respondents were presented with a number of hypothetical residential choice scenarios defined on the basis of SP experimental design. The sequential maximum likelihood estimation procedure was used to obtain taste parameters of the combined multinomial logit model. The empirical case study demonstrated practical application of the method. The hybrid model is a useful tool for urban development planning. On the basis of the results, it is concluded that telecommuting is a highly significant factor in residential location decisions.Key words: telecommuting, land use, residential location, modelling, urban development, stated preference, revealed preference.

The paper brings information on the principle of mental maps, integral part of so called "behavioural geography". It concentrates on the characterization of differences between the Gould's and Lynch's conception, or mental maps of "revealed" and "stated preference" type. A mental map of the Czech Republic and the ČSFR has been constructed and a concise methodical description of the construction has been set out, using the principal components analysis. With the help of another multiple quantitative method namely the method of stepwise regression, the multifactoral conditionality of preferences has been analyzed on the example of Czech Districts.

Abstract:

IntroductionThe increasing burden that offenders place on justice and health budgets necessitates better methods to determine the benefits of and value society places on offender programmes to guide policy regarding resource allocation. The aim of this paper is to demonstrate how economic methods will be used to determine the strength of preferences and value of violent offender treatment programmes from the perspectives of offenders, their families and the general population.Methods and analysisTwo stated preference economic methods, discrete choice experiment (DCE) and contingent valuation (CV), will be used to assess society’s and offenders' value of treatment programmes. The mixed methods process involves a literature review and qualitative methods to derive attributes and levels for the DCE and payment card values for the CV. Consensus building approaches of voting, ranking and the Delphi method will be used to further refine the findings from the qualitative phase. Attributes and their levels will be used in a D-efficient Bayesian experimental design to derive choice scenarios for the development of a questionnaire that will also include CV questions. Finally, quantitative surveys to assess societal preferences and value in terms of willingness to pay will be conducted.Ethics and disseminationEthics approval for this study was obtained from the University of New South Wales (UNSW) Human Research Ethics Committee, Corrective Services New South Wales Ethics Committee and the Aboriginal Health and Medical Research Council ethics committee. The findings will be made available on the Kirby Institute UNSW website, published in peer-reviewed journals and presented at national and international conferences.

Abstract:

Agri-food systems in the Czech Republic are currently undergoing a profound transformation toward high-value products. Appropriate policies are needed to guide this transformation, presupposing good understanding of consumer preferences. Having established a general framework for the analysis of food choice and quality perception, second part of the paper gives overview of results of stated preference evaluation studies conducted in the Czech Republic. The objective of secondary data analysis is to evaluate consumer preferences and willingness to pay for the food quality with the special attention to an evaluation of consumer preferences for health aspects of the food. The consumers’ relative preferences toward the different dimensions of a product’s quality are measured from the consumers’ perspective via their preference scores on various dimensions of quality derived from Analytic Hierarchy Process (AHP). Price premium consumers are willing to pay for the high quality product is investigated using Contingent valuation method (CV). In general, the empirical evidence supports the hypothesis that health ensuring and enhancing characteristics together with sensorial characteristics significantly affect consumers’ preferences for food and most consumers are willing to pay a price premium in order to ensure required quality of food.

Abstract:

This paper proposes foundations and a methodology for survey-based tracking of well-being. First, we develop a theory in which utility depends on “fundamental aspects” of well-being, measurable with surveys. Second, drawing from psychologists, philosophers, and economists, we compile a comprehensive list of such aspects. Third, we demonstrate our proposed method for estimating the aspects' relative marginal utilities—a necessary input for constructing an individual-level well-being index—by asking ∼4,600 US survey respondents to state their preference between pairs of aspect bundles. We estimate high relative marginal utilities for aspects related to family, health, security, values, freedom, happiness, and life satisfaction. (JEL C43, C83, D12, I31)

Abstract:

PurposeThe paper aims to explore consumer preferences for novel and other quality attributes in processed foods. It focuses on preferences for product origin, certification on food quality and standards and tradeoffs between novelty (fortification and highly processed) and other quality attributes.Design/methodology/approachIn total, 317 consumers were randomly selected at a high-end supermarket and a traditional local market in Dar es Salaam, Tanzania. Stated and revealed preference approaches were used to investigate their preferences for different attributes in processed foods. A hypothetical choice experiment was used to assess consumer preference for six baby food attributes and the tradeoffs between the attributes, while the revealed preference method included questions on consumer's actual processed food purchasing and consumption habits. In addition, consumers were asked a series of hierarchical questions assessing the motivation underpinning their choices for different products attributes.FindingsWhen making choices for processed food attributes, consumers are reluctant to choose novel technologies and have a strong preference for natural, nutritious, tasty and quality processed food attributes. However, they are willing to forego their preference for naturalness and to overcome their reluctance to trying novel technologies when the novelty is embedded with such quality benefits as nutrition, but not so when the embedded benefit is convenience. They are also willing to trade off their preference for nutrition for a sensory taste. This suggests that micronutrient deficiencies can be reduced among women and children under five by employing the appropriate strategies in processed food formulation. Further, the preference for product origin highlights the opportunity for national brands to fill the gap created by the increasing demand for processed foods in Tanzania.Research limitations/implicationsThe study claims a developing country perspective but is only representing consumers in one city in a developing country. However, this study speculates that consumers with representative characteristics in such context are likely to behave the same. Furthermore, although this study controlled for a hypothetical bias, having a hypothetical choice experiment with non-shoppers (non-purchasers) could have triggered the hypothetical bias, making participants concentrate more on non-price than price attributes.Originality/valueThe paper offers a developing country perspective on consumers' preferences for novelty in processed foods and tradeoffs with other quality attributes.

Abstract:

To quantitatively analyze travelers preference under different influence factors on transport mode, the thoughts of orthogonal design is introduced into optimizing questionnaires without the loss of information. Combined with stated preference survey method, data related to travelers preference are collected. In order to analyze survey data scientifically and roundly, BP neural network is used. By taking non-investigated options as inputs, BP neural network can figure out the scores of all options which are not be surveyed. At last a numeric example demonstrates the use of BP neural network in the analysis of demand characteristic of passenger transposition is valid and feasible.

Abstract:

This paper presents the first application of a recently proposed stated preference valuation method called contingent grouping. The method is an alternative to other choice modeling methods such as contingent choice or contingent ranking. It was applied to an afforestation program in the northeast of Spain. The attributes included (and the marginal values estimated per individual) were allowing picnicking in the new forests (€2.47), sequestering 1000 tons of CO2 (€0.04), delaying the loss of land productivity by 100 years, due to erosion in the new forests area (€0.783), and allowing four-wheel driving (€6.5), which is perceived as a welfare loss.

Abstract:

A stated-preference experiment was performed in Calgary, Alberta, Canada, to examine the nature of various influences on location decisions by various categories of small independent retail firms. A total of 287 completed observations were obtained. In each observation the respondent shop owner or manager was presented with a set of possible shop locations and asked to indicate the order of preference for those locations. These observations were used to estimate the parameter values for a range of alternative utility functions in logit models representing this choice behavior. The results indicate that all the included attributes have significant effects except for the driving time to the nearest electrical substation, which was included as an irrelevant variable to see if the method would indicate it was irrelevant. The results also indicate that the addition of one more competitor nearby is as onerous as an increase in rent of C$127 per month; a switch from a separate location on a minor road to a separate location on a major road is as desirable as a decrease in rent of C$388 per month; a switch from a separate location on a minor road to a mall is as desirable as a decrease in rent of C$665 per month; and an increase in parking charge of C$1 per hour for customers is as onerous as an increase in rent of almost C$200 per month. Some results are novel and others are broadly consistent with findings in other research, which is seen to add credence to the approach used.

Abstract:

As a countermeasure to the greenhouse gas problem, the world is focusing on alternative fuel vehicles (AFVs). The most prominent alternatives are battery electric vehicles (BEV) and fuel cell electric vehicles (FCEVs). This study examines FCEVs, especially considering hydrogen refueling stations to fill the gap in the research. Many studies suggest the important impact that infrastructure has on the diffusion of AFVs, but they do not provide quantitative preferences for the design of hydrogen refueling stations. This study analyzes and presents a consumer preference structure for hydrogen refueling stations, considering the production method, distance, probability of failure to refuel, number of dispensers, and fuel costs as core attributes. For the analysis, stated preference data are applied to choice experiments, and mixed logit is used for the estimation. Results indicate that the supply stability of hydrogen refueling stations is the second most important attribute following fuel price. Consumers are willing to pay more for green hydrogen compared to gray hydrogen, which is hydrogen produced by fossil fuels. Driver fuel type and perception of hydrogen energy influence structure preference. Our results suggest a specific design for hydrogen refueling stations based on the characteristics of user groups.

Abstract:

A declining and restructured reindeer herd is forcing some Sami into other permanent or temporary occupations. In the Swedish parts of Sami land, Sápmi, an increasing number of Sami are involved in small companies dealing with tourism that focuses on their culture. These companies, their products and their location, are today relatively well known. What the tourists demand and appreciate, on the other hand, is not so well known. The purpose of this paper is to analyse which factors matter when tourists make their decisions. Using the stated preference method, respondents were requested to evaluate a number of hypothetical alternatives. The tourists' opinions and considerations were measured in respect of three attributes; the companies' offers, the prices for these products and access. The study shows that there seems to be a considerable potential in these kinds of activity and that there is, in some respects, a gap between supply and demand.

AbstractObjective: To examine hand preference, hand skill and hand strength in university undergraduates in order to determine the most reliable index of handedness.Method: The Edinburgh Inventory, a group test of handedness by marking dots in circles, and a standard dynamometer were used with 248 (148 female, 100 male) subjects.Results: No statistically significant correlations were found between hand skill and strength, or between hand preference and strength. A significant correlation between skill and preference was found in the male right-handed group of 93 students.Conclusion: It is not possible to demonstrate whether preference or skill is the better index of handedness; a standardised method for assessment of hemispheric dominance for handedness is required; in the meantime the criterion used in a specific study should be explicitly stated in any citation of that study.

Abstract:

Value of time for trucks was estimated from stated preference data collected in California. Truckers were asked about a choice between an existing free road versus a toll facility for different combinations of travel time and cost. Estimation was based on the point of diversion at which the switch of facility occurred in the stated preference questions and also on the use of a modified logit model in which the coefficients to be estimated were assumed to be distributed lognormally across the population. Comparisons between data sets that were segmented according to business type, shipment size, and the method of driver compensation indicated that for-hire trucks tend to have higher values of time than private ones and the companies that pay drivers hourly wages have higher values of time than those who pay commissions or fixed salary.

Abstract:

Abstract Objectives Measuring consumer preferences for different food quality attributes in low- and middle-income countries (LMICs) is increasingly important for interventions and policies to better address poor nutrition and health outcomes in the context of rapidly changing food environments. Despite the importance of measuring preferences, limited research has been conducted in LMICs to develop a better understanding of what matters most to consumers. This study reviews existing methods for measuring preferences and proposes a way forward for the nutrition public health community to address this important gap. Methods Relevant papers were identified in PubMed using pre-selected Mesh terms and by searching reference lists of key review articles. Approaches identified span the fields of marketing, economics, psychology, and nutrition public health. The papers reviewed used different methods to measure preferences of various types of food attributes. Results In marketing and economics, the term conjoint analysis is used to describe a category of methods that measure the stated preference of respondents by asking them to rate, rank, or choose between competing alternatives. Within conjoint analysis, several different methods exist including discrete choice experiences, ranking conjoint analysis, and best-worst scaling and each can be used to elicit preferences about observable and unobservable attributes of foods (e.g., price, taste etc.). Within the field of psychology, several techniques have been used including the Food Choice Questionnaire and Food Choice Values. Other approaches include qualitative interviews, pile sorting, and Likert scale-based instruments. Each method has strengths and weaknesses but in general, those from marketing and economics have the benefit of resulting in a ranked choice, in contrast to Likert scales and pile sorting which can be difficult to interpret and cognitively burdensome. Conclusions Most methods have been primarily developed, validated, and used in high-income countries with much less application in LMICs. Further research is required to adapt and develop preference elicitation methods for LMICs to better measure food preferences in the context of rapidly evolving food environments.

Abstract:

Abstract Background: The desire for sons has long been recognised as a significant determinant of childbearing decisions throughout most of South Asia. This paper provides an overview of the stated desire for sons and the manifestations of son-preferring behaviour in relation to parity progression and contraceptive use. Methods: This paper uses the most recently available Demographic and Health Survey (or equivalent) data from five South Asian countries: Afghanistan, Bangladesh, India, Nepal and Pakistan. The extent of son preference in these countries is compared in terms of reported latent son preference as well as in terms of revealed son preference in relation to differential stopping behaviour, and choices about contraceptive use and contraceptive method. Results: Parity progression is driven by son preference to some extent in all five countries studied. It is found that son preference is also a major factor in determining use of permanent contraceptive methods in every country apart from Afghanistan. The association is particularly strong in Nepal, India and Pakistan. Women with fewer than two sons are generally much less likely to use permanent contraceptive methods. On the other hand, son preference has little association with temporary or traditional contraceptive use in any country. Conclusion: The desire for sons has a significant impact on fertility and contraceptive choices across much of South Asia, even in places where high fertility persists. Family planning programmes in these areas need to change deeply embedded attitudes in order to be successful. In Pakistan and Afghanistan in particular, future reductions in fertility could be hindered by high levels of son preference.

Abstract:

The financial risk evaluation is critically vital for enterprises to identify the potential financial risks, provide decision basis for financial risk management, and prevent and reduce risk losses. In the case of considering financial risk assessment, the basic problems that arise are related to strong fuzziness, ambiguity and inaccuracy. q-rung orthopair fuzzy set (q-ROFS), portrayed by the degrees of membership and non-membership, is a more resultful tool to seize fuzziness. In this article, the novel q-rung orthopair fuzzy score function is given for dealing the comparison problem. Later, the and operations are explored and their interesting properties are discussed. Then, the objective weights are calculated by CRITIC (Criteria Importance Through Inter-criteria Correlation). Moreover, we present combined weights that reflects both subjective preference and objective preference. In addition, the q-rung orthopair fuzzy MCDM (multi-criteria decision making) algorithm based on CoCoSo (Combined Compromise Solution) is presented. Finally, the feasibility of algorithm is stated by a financial risk evaluation example with corresponding sensitivity analysis. The salient features of the proposed algorithm are that they have no counter-intuitive case and have a stronger capacity in differentiating the best alternative.

Abstract:

IntroductionIn Australia, societal and individual preferences for funding fertility treatment remain largely unknown. This has resulted in a lack of evidence about willingness to pay (WTP) for fertility treatment by either the general population (the funders) or infertile individuals (who directly benefit). Using a stated preference discrete choice experiment (SPDCE) approach has been suggested as a more appropriate method to inform economic evaluations of fertility treatment. We outline the protocol for an ongoing study which aims to assess fertility treatment preferences of both the general population and infertile individuals, and indirectly estimate their WTP for fertility treatment.Methods and analysisTwo separate but related SPDCEs will be conducted for two population samples—the general population and infertile individuals—to elicit preferences for fertility treatment to indirectly estimate WTP. We describe the qualitative work to be undertaken to design the SPDCEs. We will use D-efficient fractional experimental designs informed by prior coefficients from the pilot surveys. The mode of administration for the SPDCE is also discussed. The final results will be analysed using mixed logit or latent class model.Ethics and disseminationThis study is being funded by the Australian National Health and Medical Research Council (NHMRC) project grant AP1104543 and has been approved by the University of New South Wales Human Research Ethics Committee (HEC 17255) and a fertility clinic’s ethics committee. Findings of the study will be disseminated in peer-reviewed journals and presented at various conferences. A lay summary of the results will be made publicly available on the University of New South Wales National Perinatal Epidemiology and Statistics Unit website. Our results will contribute to the development of an evidence-based policy framework for the provision of cost-effective and patient-centred fertility treatment in Australia.

Abstract:

Stated-preference surveys provide a good opportunity for obtaining information for the construction of choice models, but they run the risk of asking questions that are too complex for respondents to answer meaningfully, especially when many attributes and alternatives are considered in each question. An alternative technique is the use of adaptive conjoint analysis or adaptive stated-preference (ASP) surveys, wherein simpler questions are used, each game is dependent on the answers given to previous games, and parameters are estimated at the level of the individual. A simulation study used to test the ability of ASP to produce unbiased estimates of the mean and standard deviation of the value of time (VOT) is described. It is found that this is possible under certain conditions, namely, that a seven-point rating scale is used to obtain responses, each respondent plays three games for each parameter to be estimated, the starting estimate of VOT used should be higher than the expected final mean value of VOT, and a logit model sensitivity parameter of c = 5 is used in the binary logit model used to convert probabilities of choice into utility differences. The results of this simulation give reassurance that in addition to being easier for respondents, the ASP survey method produces unbiased estimates of the distribution of VOT (or any other parameter under consideration). Given the extreme flexibility of the disaggregate results produced by the ASP survey method, the demonstration of unbiased estimates is an important confirmation of the usefulness of this method.
