The Impacts of Attribute Level Framing and Changing Cost Levels on Choice Experiments Value Estimates AgEcon
Kragt, Marit Ellen; Bennett, Jeffrey W..
Choice Experiments (CE) are increasingly used to estimate the values of environmental goods and services. CE questionnaires represent the environmental good under valuation by varying levels of non-market attributes. Inclusion of a cost attribute enables the estimation of monetary values for changes in the non-market attributes presented. The ways in which the levels of the attributes are described in the survey - the ‘attribute frame’ - may affect respondents’ choices. Furthermore, varying levels of the cost attribute may impact CE value estimates. The challenge for CE practitioners is to identify the ‘appropriate’ attribute frames and cost levels. In this paper, the impacts of changing cost levels and the impacts of describing non-market attributes as...

Eliciting public preferences for managing the public rights of way AgEcon
Morris, Joe; Colombo, Sergio; Angus, Andrew J.; Stacey, K.; Parsons, D.; Brawn, M.; Hanley, Nick.
Public Rights of Way (PROW) in England and Wales, provides a wide range of social and economic benefits to those other than owners of land. The protection and extension of PROW are an important way of encouraging people to engage in informal enjoyment of urban and rural areas, with beneficial consequences for health and welfare. In urban areas they provide networks of mobility and interaction for people at the community level, helping to reduce reliance on motorised transport. In the rural context they define access to the countryside, critically linked to recreation and tourism, as well as providing mobility networks for local residents. This study describes the use of a Choice Experiment (CE) to derive monetary estimates the social benefits of PROW in an...

The Impact of Protest Responses in Choice Experiments AgEcon
Barrio, Melina; Loureiro, Maria L..
Not much attention has been given to protest responses in choice experiments (CE). Using follow-up statements, we are able to identify protest responses and compute welfare estimates with and without the inclusion of such protest responses. We conclude that protest responses are fairly common in CE, and their analysis affects the statistical performance of the empirical models. In particular, when the sample is corrected by protests, our results come from utility consistent models. Thus, future choice experiments should consider the role of protest responses as contingent valuation studies have done.

Using choice experiments to value river and estuary health in Tasmania with individual preference heterogeneity AgEcon
Kragt, Marit Ellen; Bennett, Jeffrey W..
Choice experiments (CE – otherwise known as Choice Modelling) have become a widespread approach to environmental valuation in Australia, with many examples assessing the tradeoffs between river catchment management and socio-economic impacts. There is, however, limited information on the values of Australian estuaries. Furthermore, none of the existing valuation studies address catchment management changes in Tasmania. The CE study reported in this paper aims to elicit community preferences for the protection of the rivers and estuary of the George catchment in north-eastern Tasmania. Results from conditional and mixed logit models show that respondents are, on average, willing to pay between $2.47 and $4.46 for a km increase in native riverside vegetation...

Preferences, Norms and Constraints in farmers' agro-ecological choices. Case study using a choice experiments survey in the Rhone River Delta, France AgEcon
Jaeck, Melanie; Lifran, Robert.
The aim of this paper is to elicit the sensitivity of farmers to payments for agro-environmental services in a context of strong agro-ecological and policy constraints. We present results from a choice experiment survey performed among the whole population of agricultural decision-makers (104) in the Camargue area. Several econometric models have been estimated, the most significant being the Latent Classes one. The estimated parameters of the utility function, together with the parameter associated with the monetary attribute provided the monetary value of each relevant agro-ecological attribute and the associated outcomes (average and risk yield).
