| Resumen: | We use a choice experiment to evaluate a hypothetical irrigation water pricing regime in Karnataka State, India. The proposed regime includes increasing the availability of water in the dry season, increasing irrigation frequency, water sharing with downstream water users, set against the introduction of a semi-volumetric irrigation price. The majority of farmers chose the status quo (SQ) option. Given the large heterogeneity in farmers’ SQ water availability, irrigation practices and current water tax payments, the SQ could not be given a unique baseline interpretation. This poses a potential problem for choice model estimation. By coding the individual SQ situation of farmers, we observed considerable increase in the explanatory power of the choice experiment models. The results may be of general interest for choice experiments of environmental goods and services with heterogeneous spatial distribution, heterogeneous respondents and/or contentious policies that are expected to elicit considerable SQ response. |

| Título: | Transferring the benefits of avoided health effects from water pollution between Portugal and Costa Rica |

| Resumen: | Two very similar contingent valuation surveys eliciting willingness-to-pay (WTP) to avoid eye irritation, gastroenteritis, and coughing episodes due to seawater pollution were conducted on visitors to beaches in Portugal and Costa Rica. Various forms of the hypothesis regarding the transfer of mean WTP between the two countries were rejected, as was the hypothesis that model parameters were drawn from the same pooled sample across countries for three different illness episodes. When compared to on-site studies in Costa Rica, benefit transfer from Portugal leads to errors typically of the order of 100 per cent. Adjusting WTP for declared income or other easily accessible socio-demographic variables does not reduce transfer error. This study shows that transfer of health benefit estimates can be potentially quite unhealthy for policy analysis, questioning whether the time and resource savings are justified in this particular transfer context. |
