PurposeConsumers are giving greater attention to the selection of food due to the improvement in income and urbanization. Meanwhile, in recent years, the vegetables' farmers in Malaysia have been reported using an excessive quantity of pesticides. The vegetables exported to Singapore and China have been rejected in 2018 and 2017 due to the presence of excessive levels of pesticides. Such incidences have created massive concern to improve the safety standard of the vegetable industry. The purpose of this paper is to evaluate consumers' willingness to pay for food safety attributes of tomato.Design/methodology/approachDiscrete choice experiments has been used, and 490 respondents have completed the survey.FindingsResults suggested that consumers were willing to pay RM4.18 more for wholesome tomato relative to slightly damage tomato. Consumers also were willing to pay RM2.75 more for organic tomato relative to inorganic tomato. They were also willing to pay RM2.30 and RM1.29 more for certified and tomato sold at supermarket relative to uncertified and tomato sold at the wet market, respectively. The willingness to pay for safety attributes of tomato also varied according to the income, age and education level of the consumers.Research limitations/implicationsIf the farmers can respond effectively to the changes in consumers demand, it can be translated into business opportunities.Originality/valueThis research able to provide relevant information related to the consumers' willingness to pay for food safety attributes of tomato in Malaysia.

The Impact

Food production is a major contributor to environmental damage. More environmentally sustainable foods could incur higher costs for consumers. In this review, we explore whether consumers are willing to pay (WTP) more for foods with environmental sustainability labels (‘ecolabels’). Six electronic databases were searched for experiments on consumers’ willingness to pay for ecolabelled food. Monetary values were converted to Purchasing Power Parity dollars and adjusted for country-specific inflation. Studies were meta-analysed and effect sizes with confidence intervals were calculated for the whole sample and for pre-specified subgroups defined as meat-dairy, seafood, and fruits-vegetables-nuts. Meta-regressions tested the role of label attributes and demographic characteristics on participants’ WTP. Forty-three discrete choice experiments (DCEs) with 41,777 participants were eligible for inclusion. Thirty-five DCEs (n = 35,725) had usable data for the meta-analysis. Participants were willing to pay a premium of 3.79 PPP$/kg (95%CI 2.7, 4.89, p ≤ 0.001) for ecolabelled foods. WTP was higher for organic labels compared to other labels. Women and people with lower levels of education expressed higher WTP. Ecolabels may increase consumers’ willingness to pay more for environmentally sustainable products and could be part of a strategy to encourage a transition to more sustainable diets.

Purpose The usefulness of risk disclosures (RDs) to support equity investors’ investment decisions is highly discussed. As prior research criticizes the extensive aggregation of risk information in existing empirical research, this paper aims to provide an attempt to identify disaggregated risk information associated with cumulative abnormal stock returns (CARs). Design/methodology/approach The sample consists of 2,558 RDs of companies listed in the S&P 500 index. The RDs were filed within 10 K filings between 2011 and 2017. First, this study automatically extracted 35,685 key phrases that occurred in a maximum of 1.5% of the RDs. Second, this study performed stepwise regressions of these key phrases and identified 67 (78) key phrases that show positive (negative) associations with CARs. Findings The paper finds that investors seem to value most the more common key phrases just below the 1.5% rarest key phrase threshold and business-related key phrases from RDs. Furthermore, investors seem to perceive key phrases that contain words indicating uncertainty (impacts) as a negative (positive) rather than a positive (negative) signal. Research limitations/implications The research approach faces limitations mainly due to the selection of the included key phrases, the focus on CARs and the methodological choice of the stepwise regression analysis. Originality/value The study reveals the potential for companies to increase the information value of their RDs for equity investors by providing tailored information within RDs instead of universal phrases. In addition, the research indicates that the tailored RDs encouraged by the SEC contain relevant information for investors. Furthermore, the results may guide the attention of equity investors to relevant text passages whose deeper analysis might be useful with regard to investors’ capital market decisions.

Birth Registration

IntroductionBirth registration remains limited in most low and middle-income countries. We investigated which characteristics of birth registration facilities might determine caregivers’ decisions to register children in Ethiopia.MethodsWe conducted a discrete choice experiment in randomly selected households in Addis Ababa and the Southern Nations, Nationalities, and People’s Region. We interviewed caregivers of children 0–5 years old. We asked participants to make eight choices between pairs of hypothetical registration facilities. These facilities were characterised by six attributes selected through a literature review and consultations with local stakeholders. Levels of these attributes were assigned at random using a fractional design. We analysed the choice data using mixed logit models that account for heterogeneity in preferences across respondents. We calculated respondents’ willingness to pay to access registration facilities with specific attributes. We analysed all data separately by place of residence (urban vs rural).ResultsSeven hundred and five respondents made 5614 choices. They exhibited preferences for registration facilities that charged lower fees for birth certificates, that required shorter waiting time to complete procedures and that were located closer to their residence. Respondents preferred registration facilities that were open on weekends, and where they could complete procedures in a single visit. In urban areas, respondents also favoured registration facilities that remained open for extended hours on weekdays, and where the presence of only one of the parents was required for registration. There was significant heterogeneity between respondents in the utility derived from several attributes of registration facilities. Willingness to pay for access to registration facilities with particular attributes was larger in urban than rural areas.ConclusionIn these regions of Ethiopia, changes to the operating schedule of registration facilities and to application procedures might help improve registration rates. Discrete choice experiments can help orient initiatives aimed at improving birth registration.

Purpose The purpose of this paper was to investigate how attention to wine labels related to preference by using quantitative measures of gaze and of the diameter of the eye pupil. We assessed whether eye fixations could predict choices and willingness to pay and whether pupil size could index the aesthetic value of wine labels. More specific goals were to identify which elements of a wine label captured attention the most and to assess whether an authentic label would be preferred by naïve consumers over other alternative labels, also designed by the same studio but excluded from the market. Design/methodology/approach Infrared eye-tracking was used to measure the amount of time spent on a specific label among four that were simultaneously shown on the computer screen. Participants also made explicit decisions about preferred labels and provided price estimates. Pupillometry was used for labels shown in isolation to obtain a physiological index of their arousing effect and aesthetic appeal. Eye fixations provided an index of what was selected by attention, whereas changes in the pupillary diameter indexed how intensively attention was focused on an item. Findings A strong positive relationship was found between the dwelling of gaze over a specific label and the degree in which a wine bottle was preferred and (virtually) chosen. The pictorial elements of the labels were fixated the most, whereas verbal information was looked at the least. Attractiveness scores of each bottle collected with one independent group of observers were able to predict the willingness to pay in another group. Moreover, pupil size changed non-linearly in relation to the hedonic values of the wine labels, indicating greater responses to the most as well as least attractive labels (i.e. for the most arousing labels). Research limitations/implications A limitation of the present experiments was that only choices and behavior of wine “novices” were probed; hence, the present findings might not be generalized to other segments (e.g. wine connoisseurs). Moreover, the present study could not specify which visual properties of a label affect preference, aesthetic value and estimates of price, as the study of these effects would require a large number and variety of label stimuli. Practical implications Eye monitoring methods could assist marketing studies of preferences and decision-making. Both wine label designers and wine producers could benefit from eye-tracking methods to improve label selection and optimize the design process of a wine label. Originality/value Although both eye-tracking and pupillometry have been used to the investigate aesthetic preferences for at least the past 50 years, the measurement of pupil diameter and eye movements to study attributes of (authentic) wine labels and their effectiveness is entirely novel. The present study confirms that measures based on eye-tracking combined to explicit choices or ratings provide complementary types of market-relevant information. Both methods provide objective, quantitative, information of the effect of the labels on consumers that is independent but predictive of actual choices and verbally reported preferences. Moreover, they appear to index different processes, pupillometry being a proxy of aesthetic value and gaze a reliable index of choice. Thus, the present findings can be of value to the academic researcher as well as industry and design practitioners.

The Impact

Purpose Important socioeconomic changes have been undergone due to the international economic crisis. In Catalonia (Spain), political changes towards independentism also occurred within the same period. The purpose of this paper is to explore the consumers’ wine preferences in Catalonia in two different scenarios. In particular, the authors have focussed the interest in those preferences regarding the regional origin of the wine. Design/methodology/approach Data were elicited from two identical discrete choice experiments performed in two times: before (2008) and during the economic crisis (2010) in Catalonia, Spain. Findings The results imply that the external common circumstances may have had a homogenising influence in consumer choices by decreasing the level of randomness of consumers’ selection. Consumers’ preferences for a Catalan origin were enhanced during the crisis, while price became the most important attribute. Research limitations/implications Ideally, the participants involved in both experiments would have been the same. Unfortunately, this was not possible to maintain and it is one of the limitations of this study. The authors are also aware that other non-controlled variables may have also played a role and the conclusions that are driven should be taken carefully. Originality/value This paper contributes to the literature of the discrete choice modelling using the recently developed Generalized Multinomial Logit Model. To the knowledge this is the first application in the literature of wine preferences to measure the impact of the contextual changes (economic and political) in Catalonia (Spain).

Demand Assessment

Abstract Significant investment is needed to improve peri-urban sanitation. Consumer willingness to pay may bridge some of this gap. While contingent valuation has been frequently used to assess this demand, there are few comparative studies to validate this method for water and sanitation. We use contingent valuation to estimate demand for flushing toilets, solid doors, and inside and outside locks on doors and compare this with results from hedonic pricing and discrete choice experiments. We collected data for a randomized, controlled trial in peri-urban Lusaka, Zambia in 2017. Tenants were randomly allocated to discrete choice experiments (n = 432) or contingent valuation (n = 458). Estimates using contingent valuation were lower than discrete choice experiments for solid doors (US$2.6 vs. US$3.4), higher for flushing toilets ($3.4 vs. $2.2), and were of the opposite sign for inside and outside locks ($1.6 vs. $ − 1.1). Hedonic pricing aligned more closely to discrete choice experiments for flushing toilets ($1.7) and locks (−$0.9), suggesting significant and inconsistent bias in contingent valuation estimates. While these results provide strong evidence of consumer willingness to pay for sanitation, researchers and policymakers should carefully consider demand assessment methods due to the inconsistent, but often inflated bias of contingent valuation.
