Valuing Warm Homes - Exploring New Zealanders' Home Heating Choices

<p>New Zealand homes have a record of being poorly heated and inadequately energy efficient. While policy makers increasingly recognise the many benefits associated with energy efficient warm homes, there is currently a lack of understanding of how New Zealanders make choices about space heating. This thesis takes a mixed method approach in order to 1) understand how New Zealanders value energy efficient heating and 2) further explore how people make decisions about home heating. Capturing the economic value of the range of benefits associated with home heating is investigated through analysing a contingent valuation study undertaken by the Housing, Heating and Health Study (University of Otago). Participants show 'willingness to pay' and related values below heater market prices. It is argued that there is some indication of split incentives issues and income constraint, and increased familiarisation with space heaters may increase willingness to pay. Evidence from focus group research suggests that while attitudes and norms are conducive to efficiently heated homes, other market and non-market factors impede pro-environmental choices. The widely recognised Kiwi stoicism of living in cold homes is not evidenced; choosing to go cold in the home may instead be rationalised as mitigating the environmental impacts associated with heating. This analysis sheds light on how intervention and how provision of information to fill the 'energy efficiency gap' could move outside the 'rational person' model of how New Zealanders make home heating choices.</p>

Willingness to Contribute to Bio-Larviciding in the Fight against Malaria: A Contingent Valuation Study among Rice Farmers in Rwanda

There is broad consensus that successful and sustained larval source management (LSM) interventions, including bio-larviciding campaigns, require embeddedness in local community institutions. Ideally, these community structures should also be capable of mobilizing local resources to (co-)finance interventions. To date, farmer cooperatives, especially cooperatives of rice growers whose economic activity facilitates mosquito breeding, have remained under the radar in designing community-based bio-larviciding campaigns. This study explores the potential of rice farmer cooperatives in Bugesera district, Rwanda, to take up the aforementioned roles. To this purpose, we surveyed 320 randomly selected rice farmers who belonged to one of four rice cooperatives in the area and elicited their willingness-to-pay (WTP) for application of Bti, a popular bio-larvicide, in their rice paddies. Results from a (non-incentivized) bidding game procedure, which tested two alternative contribution schemes showed that financial contributions would be significantly different from zero and sufficient to carry a co-financing share of 15–25 per cent. A strong heterogeneity in mean WTP is revealed across cooperatives, in addition to variation among individual farmers, which needs to be anticipated when engaging farmer cooperatives in LSM.

The Role of Sensory Perception in Consumer Demand for Tinned Meat: A Contingent Valuation Study

This study presents an analysis of consumer preferences for a new food product: Tinned Chianina meat. Respondents (N = 249) participated in a sensory test, where they were also asked to declare their willingness to pay (WTP) for the tasted product. The WTP data were collected after the sensory test by means of the contingent valuation method using a payment card elicitation format. Data were analysed with Cragg’s double-hurdle model to understand which factors influenced market participation (WTP > 0) and then the variables that influenced the declared WTP. According to our results, sensory perception played a key role in explaining both participation in the market and the magnitude of the expressed WTP. Moreover, we found that the sensory aspects have a different effect on the decision to participate in the market and on the magnitude of the expressed WTP. Smell and flavour are the most important in determining the probability of entering the market, while texture has the greatest impact on the declared WTP.

Willingness to Pay for Improved Water Supply Services Based on Asset Management: A Contingent Valuation Study in South Korea

The pressure on water infrastructure has increased due to an increase in the number of aging water pipes. Aging pipes are prone to failure, causing significant financial losses and service disruptions. The increasing number of aged pipes and limited budget for pipe rehabilitation or replacement necessitates water infrastructure asset management to ensure sustainable water supply services. In this study, contingent valuation was used to estimate the willingness to pay (WTP) and value improved water supply services through the implementation of asset management. To estimate the WTP at the individual and county levels, we performed a nationwide survey including eight provinces and 24 counties/cities with distinct water supply service performances. At the individual level, the median WTP estimated using the double-bounded dichotomous choice model was 249.50 KRW/month (0.22 USD/month). The results showed that high-level satisfaction of customers with water supply services and positive price perception of water bills resulted in a high WTP. At the county level, decreasing water supply service performances were associated with a low WTP, indicating that proper interventions by local utilities are required to achieve sustainable water supply services. Our results provide a quantitative basis for decision-making in implementation of water infrastructure asset management.

Valuation and willingness to pay for corn on the cob consumers in Mexico

The corn is a traditional food in Mexico that has been influenced by the current dynamics of the markets, causing the replacement of creole varieties by improved varieties and hybrids. Foods are characterized by a set of attributes that can be associated with a subjective evaluation, from which it is possible to approximate a utility function and determine elements for its evaluation. The objective of this work was to evaluate the Mexican consumer's willingness to pay for various types of corn and to determine which of them have a higher valuation. The methodology was based on a contingent valuation study, with a total of 356 consumers selected by snowball sampling (95% reliability and 7% error) and answering a questionnaire designed in Google forms, addressing consumer sociodemographic information, characteristics corn and their willingness to pay. The willingness to pay extra for corn was significantly influenced when the consumer determined that it is important to know if the corn comes from Creole or modified seed and if it has any certification. Creole and imported corn obtained a greater willingness to pay, giving higher valuation to these products. In conclusion, the present work explores the economic valuation of corn, where significant factors can be used to induce an effect on consumers, particularly in the revaluation of creole corn.
