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

2020, van Dijk, Jeremy, Farsi, Mehdi, Weber, Sylvain

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.

Travel Distance and Fuel Efficiency: An Estimation of the Rebound Effect using Micro-Data in Switzerland

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.

Swiss Household Energy Demand Survey (SHEDS): Objectives, design, and implementation

2017, Weber, Sylvain, Burger, Paul, Farsi, Mehdi, Martinez-Cruz, Adan L., Puntiroli, Michael, Schubert, Iljana, Volland, Benjamin

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.

Interactions in Swiss Households’ Energy Demand: A Holistic Approach

2017, Tilov, Ivan, Volland, Benjamin, Farsi, Mehdi

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.
