We examine the stability of the benefit transfer function across 42 recreational forests in the British Isles. A working definition of reliable function transfer is put forward, and a suitable statistical test is provided. The test is based on the sensitivity of the model log-likelihood to...

Increasing animal welfare standards requires changes along the supply chain which involve several stakeholders: scientists, farmers and people involved in transportation and slaughtering. The majority of researchers agree that compliance with these standards increases costs along the livestock...

When modelling data generated from a discrete choice contingent valuation question, the treatment of zero bids affects the welfare estimates. Zero bids may come from respondents who are not interested in the provision of the public good; alternatively, some zero-bidders may be protesting about...

Selectivity bias caused by protest responses in Contingent Valuation studies can be detected and corrected by means of sample selection models. This paper compares two methods: the Heckman 2-steps method and the full ML, applied to data on forest recreation - where WTP is elicited as a...

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...

In an effort to improve productivity and profits many farmers have replaced traditional livestock breeds with higher yielding alternatives. While such changes may bring about short-term economic gains, the loss of traditional livestock breeds could result in the loss of an important genetic...

We review the practice of experimental design in the environmental economics literature concerned with choice experiments. We then contrast this with advances in the field of experimental design and present a comparison of statistical efficiency across four different experimental designs...

: Data from a discrete choice experiment on improvements of rural landscape attributes are used to investigate the implications of discontinuous preferences on willingness to pay estimates. Using a multinomial error component logit model, we explore differences in scale and unexplained variance...

Practitioners of outdoor sports, such as rock-climbers, are likely to exhibit preference heterogeneity that depends on the 'keenness' with which such sports are practiced. Such an intuition is born out in at least one study using latent class discrete choice modelling (Provencher et al. 2002)....
