Summary: This paper focuses on the scope sensitivity in nonmarket valuation, particularly in discrete choice experiments (DCEs). The study reveals that scope sensitivity analysis as a validity diagnostics is uncommon in the DCE literature, and when more flexible specifications are used, the scope sensitivity tends to be inelastic. The estimated scope elasticities for people's preferences for expanding renewable energy production in Norway range from 0.13 to 0.58, showing a plausible order of magnitude.

Summary: The formulation of the cost vector is an important component in the design phase of a Discrete Choice Experiment (DCE) as it affects choice behaviour and marginal WTP estimates. This study investigates the effects of different cost vectors on choice behaviour and WTP estimates using a split-sample design. The results suggest that the cost vector does have an impact on choice behaviour and that both absolute and relative cost levels matter in decision making.

Summary: This study aimed to determine the impact of framing greenhouse gas emissions information on people's willingness-to-pay for transportation emissions reductions. Results showed that the addition of color and emoticons in the framing led to the highest increases in willingness-to-pay, while carbon tax framing had the least influence. Various socio-demographic variables and regional influences were also identified. This research contributes to improving environmentally friendly choices by policymakers and decision makers.

Summary: The paper argues that decision makers have a natural preference for diversification, with willingness to pay for it driven by risk aversion and loss aversion. In an experiment, the estimated value of diversification is around 5% of the initial amount, and risk-averse individuals are willing to pay more for diversification. These findings suggest that diversification is a fundamental preference that may help explain anomalies in portfolio choice.

Summary: Children and adolescents have definite economic preferences for environmental protection, with a higher willingness to pay for projects in their own country. The utility of environmental protection is greater for girls and teenagers, and a pro-environmental attitude reduces the likelihood of opting for continuation of the status quo. These findings are relevant to policy decisions on environmental conservation.

Summary: The construction sector plays a crucial role in energy consumption and greenhouse gas emissions. Promoting green buildings could be an effective solution to tackle environmental issues. This study conducted a choice experiment to investigate preferences and willingness to pay for different attributes of green office buildings in Shanghai. The findings indicate that respondents highly value attributes related to indoor comfort and health, as well as power saving and water saving features. People working in higher rental offices are more likely to pay for air purifier installation. Construction and manufacturing firms show higher willingness to pay for power saving and lower willingness to pay for soundproofing. Overall, foreign firms are willing to pay more for eco-friendly materials.

Summary: Inappropriate treatment of agricultural residue streams can have negative impacts on the environment, society, and economy. Bioconversion of livestock wastes using black soldier fly can recover valuable nutrients and enhance the circularity of agricultural systems. A survey of Australian farmers showed that they agreed the use of black soldier fly-derived fertilisers would improve environmental sustainability and expressed interest in using the product. Farmers preferred the product in granulated form and were willing to pay more for higher organic carbon and nutrient content. Organic and 'regenerative' farmers showed a greater willingness to pay compared to 'conventional' farmers.

Summary: This study used a Discrete Choice Experiment and a Geographical Information System to assess individuals' willingness to switch to a more virtuous energy mix. It found that young people are more likely to accept renewable energy and residents in areas with negative externalities have lower willingness to pay. Therefore, increased effort in public policies to plan the location of renewable energy facilities in a more equitable way is needed, along with better explanation and co-construction of new projects.

Summary: This paper presents a study on Tasmanian firewood consumers' willingness to pay for labelled firewood. The results show that consumers are willing to pay a premium for repurposed wood, firewood sourced from agroforestry-based operations, proceeds invested in wildlife conservation, or firewood that comes from sites closer to their residence. Additionally, consumers prefer their firewood to be accredited and regulated by independent non-profit bodies such as the Firewood Association of Australia.

Summary: This study examines households' preferences, willingness to pay, and determinants of adopting improved cook stoves in rural Ethiopia. Findings suggest that households were aware of the benefits of improved cook stoves but were constrained by technology availability and product quality. Factors such as education, income, non-farm employment, and livestock ownership influenced the adoption of new gas stoves.

Summary: This study investigates whether shareholders are willing to pay for higher levels of corporate financial, social, and environmental disclosure. The results show that shareholders are willing to pay for financial and environmental disclosure, but not for social disclosure. However, the main contribution of this study is the finding that investors are willing to pay for non-financial disclosures. The use of a choice-based conjoint experiment is a novel approach to examine this issue.

Summary: This study examines the decision-making process of Australian farmers regarding the selection and intensity of herbicide use using a random utility consistent discrete-continuous model. The proposed model offers flexibility and can accommodate decisions concerning a single herbicide. A forecasting approach based on sequential quadratic programming is employed to predict optimal herbicide types and allocations, while structural estimates are used to forecast the impact of price changes on herbicide demand.

Summary: Natural Capital Accounts are an extension of traditional balance sheets that aim to incorporate the value of nature into decision-making. In comparison to UK decision-support guidance, these accounts introduce innovations such as explicit reporting of gaps, providing confidence level information, and reporting on the ecological state of assets. These innovations make the accounts more transparent and provide a useful snapshot of the condition of natural capital assets.
