Promotion of energy-saving household appliances (ESHAs) potentially contributes to optimizing both the total quantity and efficiency of household energy consumption. Differences in urban consumers' preference for higher-grade ESHAs as well as its influencing factors in cities with hierarchical socioeconomic levels remain elusive. Targeting 55 Chinese cities pertaining to three levels of socioeconomic development, we distribute questionnaires designed to cover both demographic and consciousness factors. By combining Contingent Valuation Method and multiple linear regression, the extra willingness to pay (WTP) for Grade-1/2 appliances compared with Grade-3 appliances is measured, and the influence factors on the WTP as well as consumers with highest WTP are identified. The extra WTP for Grade-1 appliances in First-, Second- and Third-level cities is 44.1%, 42.3% and 32.7%, respectively. The influences of age, household income, having children or not and monthly electricity bill parallel the socioeconomic level, while gender and schooling affect differently across socioeconomic levels. Consumers in less developed cities focus more on their affordability for the ESHAs, and in more developed cities have better environmental consciousness. Subsidies for consumers, such as those having master degree or above in First-level and Second-level cities, and having children in Third-level cities will increase their WTP. The findings provide insights for policy interventions aimed at boosting the purchase behavior for ESHAs according to local conditions for control of both household energy consumption and carbon emissions. [Display omitted] • Extra WTP for Grade-1/2 appliances in different levels of cities is quantified. • Critical factors affecting the WTP and consumers having highest WTP are identified. • Contingent valuation method and multiple linear regression model are combined. • WTP for Grade-1 appliances rises with the improvement of socioeconomic development. • Government subsidies help to increase the WTP for some certain consumer groups.

A number of stated preferences studies have estimated a monetary value for the gains in life expectancy resulting from pollution control, using a Value of a Life Year (VOLY) approach. However, life expectancy gains are a complex concept and no attempt has been made, to date, to investigate peoples' understanding of what it is they are being asked to value. Past practice has been to focus on the outcome of a policy i.e. a gain to the average person of X months', providing no details on how the individual receives, or experiences this gain, a potentially important attribute to value. This paper sets up and reports the results from a structured debriefing exercise to qualitatively investigate an alternative approach which explicitly emphasises how this gain is delivered (on-going reductions in the risk of death). We find that, for the majority of respondents, the approach is effective in communicating the on-going nature of the gain and reduces or eliminates the use of the (incorrect) heuristic that it is an ‘add-on’ at the end of life, in poor health. Further refinements are required, however, to communicate the cumulative nature of these risk reductions and the lack of impact on quality of life. The lesson for stated preference studies in general is that structured debriefings can be very useful, highlighting such issues as the persistence of ill-defined attributes and the difficulties that respondents may encounter setting aside their preferences over attributes of the good that should not be included in the valuation.

Abstract: Curbside recycling is a tool that communities use to reduce the need for landfill space. This study provides contingent valuation estimates of household willingness to pay (WTP) to continue a curbside recycling program in the face of budget cuts. Comparisons of two forms of the contingent valuation method (CVM) are provided: a single bounded referendum and a payment card. Neither approach emerges as unambiguously superior. Response rates were virtually identical. Both approaches show that support for curbside recycling is highly sensitive to price. Regression results from the payment card provided a more thorough identification of socio-demographic variables associated with WTP than the referendum, but the explanatory power of the two regressions did not differ significantly. The referendum estimates of mean WTP exceed those from the payment card, although the disparities are less than those typically reported in the CVM literature. Local policy makers cited the CVM results as influencing their decisions regarding funding options for the future of the program, and seemed to appreciate the fact that the two approaches provided a fairly narrow range of estimates of WTP. In an era when more of the burden of financing of environmental programs is being shifted to the local level, use of CVM to estimate the WTP of consumers for highly disaggregated goods and services designed to achieve environmental improvement will likely become more relevant to local decision makers who are interested in understanding their constituents'' views.

Despite the multifarious benefits of improved cooking stoves (ICSs) over traditional biomass stoves, the ICSs adoption rate in rural Bangladesh remains nominal. This paper provides evidence that there is a growing demand for this environmentally friendly and less-hazardous stove. Using a discrete choice experiment (DCE) technique, we surveyed 259 sample households in the south-western region of Bangladesh. The results from the mixed logit model suggest that households are willing to pay (WTP) about $7 on average for a 'realistic' (i.e., one unit or 25 %) reduction in fuel consumption and smoke emission. Moreover, we found that a one-unit (33 %) reduction of cooking time and maintenance frequency increases households' WTP by about $3 and $5 respectively. Finally, this study underscores that extensive promotion, lower installation costs and higher social awareness about health risks and environmental degradation are likely to promote ICSs adoption. • A discrete choice experiment (CE) uses to elicit households' preference for ICSs. • This study conducted in the south-west region of Bangladesh. • Households value for fuel consumption, smoke emissions and maintenance frequency. • Extensive promotion and lowering installation cost increase demand for ICSs.
