; ; 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. - PublicationAccès libreCommitments and sunk costs in private mobility: A study of Swiss households facing green transport choices(Neuchatel University of Neuchatel Institute of Economic Research, 2020)
; ; 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. - PublicationMétadonnées seulement

; ; 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. - PublicationMétadonnées seulementReduktion der Energienachfrage von Haushalten – erfolgversprechende Schritte auf einem langen Weg(Basel SCCER-CREST Work Package 2, 2018-4-30)

- PublicationMétadonnées seulementInteractions in Swiss Households’ Energy Demand: A Holistic Approach(Neuchâtel University of Neuchâtel Institut de Recherches Economiques (IRENE), 2017)
; ; This article explores the interactions between direct and embodied energy requirements of households in Switzerland in order to assess the net impacts of standard energy policies focusing exclusively on direct energy use. For this purpose, we estimate direct and embodied energy demand of Swiss households by combining consumption data of a national expenditure survey with corresponding data on energy intensity mainly from life-cycle analysis. We find strong evidence of complementarity between direct and grey energy by first estimating model parameters in a system of equations setup. In particular, the analysis of various socio-economic and psychological determinants allows us to identify a non-linear relationship between energy demand and income, which suggests that energy possesses certain “luxury features” that go beyond staple resources. An additional indication that households in Switzerland use direct and indirect energy in a complementary manner is provided by the coefficient of cross-equation correlation of residuals in our system. Finally, we analyze the causal relationship between both energy domains by the method of instrumental variables and find indicative evidence of a positive causal effect of embodied on direct energy demand, but not the other way round. From a policy perspective, our findings are important as they suggest that the wide-spread policies targeting direct energy consumption are unlikely to cause a substantial shift in household energy demand from the direct to the indirect domain.
