    Les intentions contradictoires des Suisses vis-à-vis de leur consommation d’énergie

    Cet article discute les intentions des ménages suisses de réduire leur consommation d'énergie. Il examine leurs connaissances en matière d'énergie ainsi que l'acceptation et la visibilité de la taxe CO2. Les données utilisées proviennent de l'enquête Swiss Household Energy Demand Survey (SHEDS), effectuée annuellement depuis 2016 sur un échantillon d'environ 5'000 ménages suisses. Notre analyse fait ressortir un écart entre les villes et les communes non urbaines. Bien que la taxe CO2 bénéficie du soutien de la majorité des répondants, elle manque de visibilité. La plupart des gens croient en son efficacité pour les entreprises mais non pour les ménages, et parmi les mé-nages directement concernés, beaucoup ne savent pas qu'ils sont affectés par la taxe. Notre ana-lyse fait également ressortir une disjonction entre les intentions et les connaissances, remettant en question le lien présumé entre information et action.

    Commitments and sunk costs in private mobility: A study of Swiss households facing green transport choices

    This paper experimentally investigates the existence of behavioural deviations from the oft-assumed rationality in private transport decisions, avoiding the selection-biases in revealed data. Through a choice experiment answered by 995 Swiss respondents, we explore the linkages between long- and medium-term travel investment decisions, and the choice of transport mode. We test the existence of commitment device usage in car and public transport pass purchases, and the sunk cost fallacy, as well as the impact of electric vehicles on mode choice. We find little evidence to support the existence of commitment devices, and no sunk cost fallacy. We further show that electric vehicle owners are equally likely to commute in their car, however use a greater mix of transport modes for leisure and long-distance trips. Our results support the importance of marginal travel costs in transport policy, as well as demonstrate the wide impact of rising EV consumption.

    Turn It Up and Open the Window: On the Rebound Effects in Residential Heating

    This paper investigates how households respond to efficiency improvements of their heating system. The analysis is based on the stated preference approach with an innovative choice experiment. The design includes questions to quantify both the direct and indirect rebounds. A series of easy discrete possible changes have been suggested to prime the respondents for deciding on potential actions impacting their heating service demand. Responses to these qualitative choices are moreover used to cross-validate the quantitative results. Overall, we find relatively low direct rebound effects. However, after accounting for the indirect rebound calculated using energy embodied in goods and services purchased by re-spending initial savings, we estimate an average total rebound of about one third. The econometric analysis points to substantial variations across individuals that are partly explained by observed characteristics. The results are consistent with the conjunction that heating is a basic need which calls for little rebound in high-income groups.

    The Swiss Household Energy Demand Survey (SHEDS) has been developed as part of the research agenda of the Competence Center for Research in Energy, Society, and Transition (SCCER CREST). It is designed to collect a comprehensive description of the Swiss households’ energy-related behaviors, their longitudinal changes and the existing potentials for future energy demand reduction. The survey has been planned in five annual waves thus generating a rolling panel dataset of 5,000 respondents per wave. The first two waves of SHEDS were fielded in April 2016 and April-May 2017. This paper elaborates on SHEDS's general objectives, design, and implementation. It also reports a series of practical examples of how the datasets are being used in empirical analyses.

    Travel Distance and Fuel Efficiency: An Estimation of the Rebound Effect using Micro-Data in Switzerland
    (University of Neuchâtel, 2014)
    Weber, Sylvain 
    ;
    Farsi, Mehdi 
    We estimate the rebound effect for private transportation using cross-section micro-level data in Switzerland for 2010. Our simultaneous equations model accounts for endogeneity of travel distance, vehicle fuel intensity and vehicle weight. Compared to the literature, our paper provides an important contribution as micro-level data and simultaneous equations models have seldom been used to estimate the rebound effect. Moreover, among the distance measures we use, one is highly reliable as it was recorded using GIS (Geographical Information System) software. Our results, obtained by 3SLS, point to substantial direct rebound effects between 75% and 81%, which lie at the higher end of the estimates found in the literature. OLS estimates are however much lower and seem to under-estimate the rebound effect.
