How visual attention affects choice outcomes: An eyetracking study
The 3rd International Winter Conference on Brain-Computer Interface, 2015Co-Authors: Yiyu Chen, Riccardo Scarpa, Vincenzina Caputo, Rodolfo M. Nayga, Siamac FazliAbstract:This study combines economic data collected through a choice experiment method with eye movements recorded using eye tracking technology to analyze how visual attention affects choice outcome. Our results show that subjects who spent more time on the area of interest of specific product information valued them more. Consistently with the economic theory, for example, the longer the time spent on visualizing the Price Attribute, the higher the sensitivity to Price increases. Our results also indicate that the model performance can be improved when accounting for visual saliency in choice decision.

Does money talk? — The effect of a monetary Attribute on the marginal values in a choice experiment
Energy Economics, 2014Co-Authors: Claudia Aravena, Peter Martinsson, Riccardo ScarpaAbstract:When designing choice experiments for nonmarket valuation the role of the Price Attribute is of major importance. In the energy sector the uncertainty of future direction of changes in Prices makes it difficult to include an adequate Price vector in the design. We separately investigate the implication of using Price vectors with increases and decreases in tariffs from current levels, on marginal value estimate from choice experiment data developed using prospect theory. In addition, we also analyse the effect of excluding the Price vector on these marginal values. By and large, our results support the neoclassical theory as we find that the means of the conditional estimates of the marginal values of Attributes are unaffected by the direction of the Price change and from exclusion of the Price Attribute. However, the distributions show a larger spread of values when the choice experiment implies a tariff decrease, which may have policy implications.

Does Money Talk? The Effect of a Monetary Attribute on the Marginal Rate of Substitution in a Choice Experiment
2006Co-Authors: Riccardo ScarpaAbstract:The effect of a Price Attribute expressed either in positive, negative values or being excluded in a choice experiment is studied. These issues are investigated for households' marginal willingness to pay to introduction of wind power generation in southern Chile, as well as on marginal rate of substitution between different Attributes or characteristics of wind farms projects. Our results indicate significant differences in marginal willingness to pay and marginal rate of substitutions when different specifications of the Price vector are applied. However, based on a comparison between direct ranking of four alternative wind-farms and the implicit ranking based on the estimated model, did not result in a significant difference between the Price vectors. In the end of the paper, we discuss implication of our findings for policy makers.

Exploring the potential of local market in remunerating water ecosystem services in Cambodia: An application for endogenous Attribute non-attendance modelling
Water Resources and Economics, 2019Co-Authors: Tina Rambonilaza, Mélodie NeangAbstract:Within South East Asia, certification and local market development may play an important role in incentivizing farmers to continue with nature-based solutions delivered by organic or traditional farming practices and avoid using environmentally detrimental production techniques. The purpose of this study is to use economic valuation in order to achieve an empirical understanding of local consumer preferences for different Attributes of rice products. Application of the agrarian system approach reveals that rice cultivation systems observed in the Tonle Sape Lake of the Mekong River Basin in Cambodia (our study case) may target three ecosystem services that present the characteristics of public goods and may benefit consumer support. A choice experiment survey was administered among local consumers in the city of Phnom Penh in 2013. Econometric analysis indicates high rate of non-attendance for the Price Attribute. It also suggests that 17% of the respondents made their choices neglecting Attributes describing ecosystem services. However, there are evidence of consumers' willingness to pay (WTP) for certified organic rice higher than the Price-premium observed on the local market. Furthermore, there is additional WTP value for the preservation of ecosystem services. We discuss the implications of our findings on potential payment for ecosystem services in the specific case of rice.

the asymmetric impact of Price Attribute performance on overall Price evaluation
International Journal of Service Industry Management, 2005Co-Authors: Giovanna Padula, Bruno Giuseppe BusaccaAbstract:Purpose – To investigate the theoretical foundations of Price as a multi‐dimensional component of value and to examine the nature of the relationship between Price‐Attribute perception and overall Price evaluation.Design/methodology/approach – The economic theory of the distribution of surplus across customers and the equity theory are used to develop the hypotheses about the multi‐dimensional nature of the Price construct. Prospect theory is used to predict the relationship between Price‐Attribute performance and overall Price evaluation. Data were collected through a structured questionnaire regarding mobile communications operators in Italy. After carrying out a principal factor analysis, several regression models were run to test the hypotheses.Findings – The results confirm that Price is a multi‐dimensional construct (i.e. made up of cheapness, fairness and variety), yet they do not fully support the prospect theory predictions.Research limitations/implications – Multi‐item Price measurement scales n...

Market values for olive oil Attributes in Chile: a hedonic Price function
British Food Journal, 2015Co-Authors: Rodrigo Romo Muñoz, Mario Lagos Moya, Jose Maria GilAbstract:Purpose – Focused on the olive oil sector in Chile which is a non-traditional market (both in production and consumption), the purpose of this paper is to determine the implicit value of the most relevant Attributes of olive oil on the final Price charged by supermarkets to consumers through the hedonic pricing methodology. Design/methodology/approach – Field work was carried out between September and October 2012 in 12 supermarkets belonging to the four most important Chilean retail chains. A log-linear Price-Attribute function was used to estimate the hedonic Price function. The sample included 248 observations olive oil Prices available to consumers in the leading supermarkets in the city of Chillan (Chile). Findings – The model estimation results led to the observation that the Attributes that most positively influenced final Price are oil acidity level, tin can container of imported oil, and origin. On the other hand, the Attributes that most negatively influenced final consumer Price are retailer ho...

Consumers' preferences towards biodiesel in the Spanish transport sector: A case study in Catalonia
2014Co-Authors: Zein Kallas, Jose Maria GilAbstract:In this paper, we analyse the opinions, attitudes and willingness of consumers to pay for biodiesel as an alternative to diesel in Barcelona province. Data were gathered from face-toface structured questionnaires from 300 diesel car owners/users that regularly purchase fuel. A variation of the traditional choice experiments (CE) was used by excluding the Price Attribute from the design. In a subsequent contingent valuation (CV) exercise, respondents were asked to state their maximum willingness to pay (WTP) for their preferred choice sets using the “payment card” format. The relative importance of the Attributes and levels were calculated by estimating a random parameter logit model. The results demonstrated, contrary to the literature in Spain, that consumers were not willing to pay for biodiesel, especially when its production may negatively affect food Prices. The main limitation was that car manufacturers do not recommend its use. The public authorities are asked to work jointly with the automotive industry to address this drawback.
