WP489. How Effective are Energy Labels? Evidence from the 2021 EU Reform

Energy labels are often used to promote the adoption of more energy-efficient domestic appliances. This paper provides evidence on the impact of the 2021 revision of the EU energy labeling regulation using product-level sales data on refrigerators in four European countries (Belgium, France, Germany, and Poland). We first document substantial cross-country differences in sales-weighted energy consumption, reflecting differences in product portfolios and consumer preferences. Controlling for product characteristics, average energy consumption declines by between 3.3% in France and 4.2% in Belgium following the reform. We subsequently estimate a product-level demand model that incorporates energy labels in utility either directly or through their associated 15-year electricity costs. The results indicate that consumers undervalue future energy costs under both labeling regimes, although the degree of undervaluation declines under the new labels. Counterfactual simulations suggest that the labeling reform generated only modest energy efficiency gains. Larger gains could be achieved through alternative policies: stricter minimum standards (banning the least efficient appliances) or fiscal incentives (a feebate scheme subsidizing efficient appliances while taxing inefficient ones).

WP461. Awareness and Impact of Energy Labels on Purchases of Household Appliances in the EU

This paper examines Eurobarometer survey data from 27,438 individuals across 28 EU Member States in 2019 to evaluate the awareness and impact of EU Energy Labels. Specifically, we analyze the role of socioeconomic characteristics such as age, gender, education, financial stability, and political engagement. Our results suggest that individual characteristics have a greater effect on the influence of labels on purchase decisions than on label awareness. However, significant heterogeneity across countries persists even after controlling for individual characteristics. Using our model, we conduct three exercises in which we assume a policymaker can either increase label awareness among all unaware individuals or target those with specific characteristics, and we demonstrate the resulting impact on the share of people whose purchases are influenced by the label. The findings reveal that even when label awareness is at its highest level, it does not necessarily translate into substantially higher influence on purchasing decisions in some countries. Additionally, at the country level, certain socioeconomic and political variables are positively correlated with label awareness.

WP311. Preferences for demand side management—a review of choice experiment studies

This review of choice experiment (CE) studies deals with the valuation of electricity supply attributes in the residential sector. We consider the willingness to pay and the willingness to accept changes in the electricity supply. The results could be used to determine consumers' preferences for demand-side management (DSM) programs and could serve as a reference for formulating policies. DSM is an option for constructing a low-carbon electricity system, improving energy efficiency, and achieving the sustainable development of an economy. The results from CEs justify investment in new solutions. The research shows that consumers are open to DSM, but they prefer simple programs to complex ones. Decision-makers could introduce DSM programs that enable power outages and provide compensation for households. The societal advantages of DSM are not obvious to consumers, so the implementation of DSM requires communication and more research on peoples' preferences.

WP278. Impact of beliefs about negative effects of wind turbines on preference heterogeneity regarding renewable energy development in Poland

We investigate individuals' preferences for renewable energy development in Poland. Our main objective is to examine whether preferences for avoiding externalities from renewable energy development near respondents' place of residence are influenced by their personal beliefs about the negative effects of wind turbine activity. We focus on attitudes towards wind power because it has had the most dynamic development among all renewable energy sources in Poland. To elicit values on avoiding renewable energy externalities, we use a choice experiment (CE) approach. To conduct our analysis we applied a theoretically robust econometric approach, the hybrid mixed logit model. From our analysis of data from a large sample of the Polish population, we find that beliefs about wind turbine have distinct negative effects on respondents' preferences concerning renewable energy development. Respondents who generally have an opinion about potential wind turbine effects would like to have input on renewable energy development in their neighbourhood. Latent beliefs that wind power is not harmful enhance respondents' preferences for implementing a wind energy project and enhance preferences against solar power development. These beliefs appears to be significantly correlated with respondents' marginal utility of money.

WP260. Disentangling the effects of policy and payment consequentiality and risk attitudes on stated preferences

Incentivising respondents to truthfully reveal their preferences in stated preference surveys requires that they believe their survey responses can influence decisions related to the outcome in question (policy consequentiality) and that they will have to bear their share of coercive cost if the outcome is implemented (payment consequentiality). We investigate the effects of these two aspects of consequentiality on stated preferences in a field survey concerning renewable energy development in Poland. We find that beliefs in policy and payment consequentiality strengthen respondents' interest in having the project implemented, but policy consequentiality decreases, while payment consequentiality increases their sensitivity to the project cost, thus increasing or decreasing their willingness to pay, respectively. We conclude that the two components of consequentiality should be addressed separately in stated preference studies. Additionally, we inquire the theoretically speculated links between respondents' perceptions about policy and payment consequentiality and their risk attitudes, finding no significant relationship.

WP227. Gain and loss of money in a choice experiment. The impact of financial loss aversion and risk preferences on willingness to pay to avoid renewable energy extarnalities.

We examine how the direction of price changes affects the value people place on avoiding renewable energy externalities in Poland. Additionally, we investigate the influence of individuals' financial loss aversion and financial risk preferences on this valuation. In our study we conduct a choice experiment survey in which respondents' choices indicate the value they place on avoiding wind, solar, and biomass externalities. We combine this survey with a financial lottery choice task that elicits the respondents' risk preferences and degree of loss aversion. In the choice experiment we use both increases and decreases in electricity bills to depict the uncertain effect of new sources of energy generation on the current price level. This design allows us to investigate if obtained values are independent of the payment mechanism. In the analyzed context, our results indicate that marginal utility of money seems to be lower with a rebate on the energy bill than with a surcharge. Moreover, financial risk preferences affect people's choices in a case of a surcharge, while loss aversion for money affects them in the case of a rebate. We find that the more loss averse people are with regard to money, the more they require compensation before they accept externalities from renewable electricity production. In contrast, the more risk seeking people are in a financial domain, the less cost sensitive they are and the more willing they are to pay for proposed changes in renewable electricity generation.

WP167. Marine trade-offs: comparing the benefits of off-shore wind farms and marine protected areas

The drive to increase renewable electricity production in many parts of Europe has led to an increasing concentration of location of new sites at sea. This results in a range of environmental impacts which should be taken into account in a benefit-cost analysis of such proposal. In this paper, we use choice modelling to investigate the relative gains and losses from siting new windfarms off the coast of Estonia, relative to the option of creating a new marine protected area. Methodologically, the paper makes a contribution by showing the ability of the latent class mixed logit model to represent both within-and between-class preference heterogeneity, and thus its power to provide a more sophisticated representation of preference heterogeneity than latent class or mixed logit approaches. The paper is also the first to use the latent class mixed logit in willingness-to-pay space for environmental goods.
