A spatial-based model of multiple discrete continuous demand for assessing recreational use of nature sites
This study proposes the use of a spatial-based travel cost model of multiple discrete/continuous demand to analyze recreational visits to five selected Italian National Parks. The proposed model has a spatial structure which allows us to capture potential patterns of environmental and economic dependency that may influence the destination choice and the number of trips taken to each destination. The model is estimated from revealed preference dat…
Sustainability in e-commerce food shopping
Purpose This study aims to explore the key factors that influence consumers’ positive or negative image of sustainability in e-commerce food shopping (EFS). Design/methodology/approach Data were collected through an online questionnaire with 2,039 participants from New Zealand and the United Kingdom. An open-ended question was used to explore consumers’ perceptions toward sustainability in EFS. A linear regression analysis was conducted to associ…
Reporting nutritional information on wine packaging
At the end of 2023, EU Commission mandated the adoption of nutritional labelling on wine products. This was intended to tackle irresponsible drinking behaviour and excessive energy intake from alcohol, but the alcohol industry stakeholders have remained skeptical. In this study, we seek clarification on: (1) whether nutritional labelling on alcoholic beverages can nudge consumers toward lower alcohol and hence lower calorie choices, (2) whether i…

Response Times and Subjective Complexity of Food Choices
Accurate collection of response times is one of the main advantages of web-administered stated choice experiments and it can be thought of as a behavioral indicator of cognitive effort. We use data from a food choice experiment administered across three countries and estimate a panel Mixed Multinomial Logit Model to obtain individual-specific utility weights. These are used to construct two utility-based measures of contextual choice complexity, …
Do city dwellers care about peri-urban land use? The case of environment-friendly agriculture around Milan
Undeveloped land adjacent to urban areas has a strong potential to generate high amenity values to urban dwellers via the adoption of environment-friendly agricultural practices. Yet, there is a lack of specific policy measures tailored to unlock such potential and a scant knowledge of the preferences of the main beneficiaries. Analysis of data from a Choice Experiment in the municipality of Milan based on current policy deliverables shows that a…

Stability of Willingness-to-Pay for Coastal Management
A key assumption of stated preference methods is that individuals have well-formed preferences that are robust over time. Both the discovered and constructed preference perspectives imply this is not necessarily the case. There can be a large situational component to expressed preferences that add to the uncertainty of sampling error. Most non-market valuation studies only collect data from one point in time so the degree of temporal variability …

The effect of within-season variability on estimates of recreational value for trout anglers in New Zealand
Recreational benefit estimates can be substantially improved by incorporation of data on attributes that are averaged over shorter periods of time so as to better represent within-season variability. This approach may be advantageous across a wide range of non-market valuation settings. We use angling survey data that includes bimonthly data on angler demand, water quality and fish weight in the Rotorua Lakes and compare our results with those ob…
Valuing biodiversity enhancement in New Zealand's planted forests
Planted forests are increasingly recognised for the provision of habitats for species threatened with extinction. Despite this development, a limited number of empirical studies have been undertaken to estimate the economic value of this ecosystem service. New Zealand's planted forests provide habitat to at least 118 threatened species. These forests can be managed to increase the abundance of many of these species. We present findings from surve…

Modelling attribute non-attendance in choice experiments for rural landscape valuation
Non-market effects of agriculture are often estimated using discrete choice models from stated preference surveys. In this context we propose two ways of modelling attribute non-attendance. The first involves constraining coefficients to zero in a latent class framework, whereas the second is based on stochastic attribute selection and grounded in Bayesian estimation. Their implications are explored in the context of a stated preference survey de…
Using Choice Experiments to Explore the Spatial Distribution of Willingness to Pay for Rural Landscape Improvements
We report findings from a choice experiment survey designed to estimate the economic benefits of policy measures to improve the rural landscape in the Republic of Ireland. Using a panel mixed logit specification to account for unobserved taste heterogeneity we derived individual-specific willingness-to-pay (WTP) estimates for each respondent in the sample. We subsequently investigated the spatial dependence of these estimates. Results suggest the…
Utility in Willingness to Pay Space
We compare two approaches for estimating the distribution of consumers' willingness to pay ( WTP ) in discrete choice models. The usual procedure is to estimate the distribution of the utility coefficients and then derive the distribution of WTP , which is the ratio of coefficients. The alternative is to estimate the distribution of WTP directly. We apply both approaches to data on site choice in the Alps. We find that the alternative approach fi…
Design efficiency for non‐market valuation with choice modelling
We review the basic principles for the evaluation of design efficiency in discrete choice modelling with a focus on efficiency of WTP estimates from the multinomial logit model. The discussion is developed under the realistic assumption that researchers can plausibly define a prior belief on the range of values for the utility coefficients. D ‐, A‐ , B‐ , S‐ and C‐ errors are compared as measures of design performance in applied studies and their…

Destination Choice Models for Rock Climbing in the Northeastern Alps
Rock climbers are likely to exhibit preference heterogeneity dictating the way with which such sport is practiced. This has a reflection on the population’s structure of recreational values of rock-climbing destinations, their attributes, and to land management policies. We test this hypothesis on a panel of destination choices by a sample of members of the Italian Alpine Club. Using a latent-class, random utility approach we find evidence in sup…
