| Summary/Abstract |
In this article, we investigate the heterogeneity in the responsiveness of Swiss household electricity demand to changes in prices and income. We focus on segments of consumers with different intensities of electricity consumption by using a panel quantile regression approach. This estimation strategy is applied to a rich micro-level longitudinal data set of 3880 observations from more than 1400 households, matched with a unique price data set extracted from the Swiss electricity regulator's online sources. While the findings show an inelastic electricity demand across all groups, an interesting pattern of variation emerges between lower and upper quantiles of electricity demand, respectively frugal and intensive users. Results show that households in the first conditional quartile and at the median react significantly to changes in prices, while those at the lowest quantile and upper quantiles exhibit insignificant price elasticities. The main policy implications of this work concern the design of price-based measures for reducing electricity consumption in the residential sector and the possibility of accounting for individual responses in tailoring policies for specific consumer segments.

| Summary/Abstract |
This article analyzes the interactions and possible trade-offs between direct energy consumption and embodied energy requirement of households in Switzerland in order to assess the net impacts of standard energy policies focusing exclusively on direct energy use. Direct and embodied energy demand of Swiss households are estimated by combining consumption data of a national expenditure survey with data on energy intensity from life-cycle analysis. Using a system of equations and an instrumental variable approach, we find that both domains are driven by same determinants, but that there is no evidence for significant substitution between them. We also find an increasing effect of income on both domains, with particularly important effects on embodied energy. From a policy perspective, our findings highlight a concern that economic growth could bring about an increasing global energy demand through energy requirement for non-energy commodities. However, the wide-spread policies targeting direct energy are unlikely to cause a substantial shift in household consumption to embodied energy.
