Contingent Valuation Versus Choice Experiments: Estimating the Benefits of Environmentally Sensitive Areas in Scotland: Comment
No full textFollowing Boxall et al. 1996, Hanley et al. (1998) compare welfare measures derived from contingent valuation (CV) to those derived from choice experiment (CE). Using the same Gumbel distribution assumption of the unobserved component of indirect utility, they estimate welfare measures that they expect to be the same. However, they fail to acknowledge that the indirect utility specifications underlying the two sets of estimates differ. Hence, they do not compare like with like and the difference in welfare estimates cannot be definitely attributed to the difference in the two stated preference methods employed. This comment argues that their econometric analysis is flawed and does not support many of their concluding remarks. Further, disagreement is expressed with their alleged findings on the potential performance of CV in benefit transfer studies

Preference-Based Segmentation Via Mixed Logit: The Case Of Extra-Virgin Olive Oil Across Urban Markets
No full textThe paper presents some results from a stated-preference study that compares three samples of urban consumers of extra-virgin olive oil from three representative Italian cities: Naples (South), Rome (Centre) and Milan (North). A series of multinomial logit models are estimated from choice experiments responses and tested for unobserved heterogeneity for EU labelling informing on PDO/PGI, organic and place of origin attributes. The consequences of such form of heterogeneity are ashed out with respect to issues of market segmentation on the basis of the pattern of correlation across preferences as estimated from mixed logit models. Results indicate that product origin matters di erently in di erent cities, while the sample from Naples is the least heterogeneous the Milan and Rome samples display highest taste heterogeneity, but also stronger intensity of taste

Perceived risks of mountain landslides in Italy: stated choices for subjective risk reductions
No full textMountain landslides have occurred in countries such as Italy regularly throughout recorded history, often resulting in fatalities. Because of this, policies that would reduce landslide fatality risk need to be carefully formulated. As a first step in the exploration of preferences for these risk-reducing policies, we examine public perceptions of risk for landslides and related events
Market Segmentation via Mixed Logit: Extra-Virgin Olive Oil in Urban Italy, Journal of Agricultural & Food Industrial Organization
No full textThe paper presents some results from a stated-preference study that compares three samples of urban consumers of extra-virgin olive oil from three representative Italian cities: Naples (South), Rome (Centre) and Milan (North). A series of multinomial logit models are estimated from choice experiments responses and tested for unobserved heterogeneity for EU labelling informing on PDO/PGI, organic and place of origin attributes. The consequences of such form of heterogeneity are flashed out with respect to issues of market segmentation on the basis of the pattern of correlation across preferences as estimated from mixed logit models. Results indicate that product origin matters differently in different cities, while the sample from Naples is the least heterogeneous the Milan and Rome samples display highest taste heterogeneity, but also stronger intensity of taste
Estimating the willingness to pay for Warmer and Drier Homes
No full textNew Zealand is one of several countries to use subsidies for retrofitting
insulation and installing improved heating devices such as heat pumps.
The valuation of these devices by the affected populations remains
unknown. We investigate willingness to pay for such devices, using a
choice experiment with a sample of Pacific Islanders in the upper North
Island. This is a high-risk group for respiratory disease, who typically rent
crowded and inadequately heated dwellings. Using both conditional logit
and panel mixed logit models, we find reasonably precise estimates of the
willingness to pay for four improved heating and humidity control
devices, which would cover the capital costs of two of the devices, and
about three-quarters of the cost of the other two devices
The Participation Dilemma: A Survey of the Empirical Literature on International Environmental Agreement Ratification
Get PDFSeveral of the most pressing environmental problems involve transboundary issues and can be solved only through international cooperation. Hence, a successful policy response requires a good understanding of international environmental agreements—the primary tool for international cooperation. What motivates participation in environmental agreements, and how can it be increased? These questions have been addressed in economic research, mostly using game theoretical approaches, in models that predict the optimal emission abatement and participation levels. Our survey focuses on a contiguous body of work: the empirical literature on environmental treaty participation. The scope of this paper is to compile the first detailed survey of the empirical literature on participation in environmental agreements, summarize its findings, and enable better comparison with theoretical predictions
Cue versus independent food attributes: the effect of adding attributes in choice experiments
