Householdfleet adaptation as reaction to price regulations: A stated adaptation experiment on the promotion of electric vehicles

Abstract

The goal to limit global warming requires a shift to electric vehicles and a reduction of vehicles in total. To achieve this transition, governments could design price regulations effectively. The potential effect of different price regulations has been assessed by surveying 466 respondents. After providing detailed information on all mobility tools in the household, respondents were faced with four scenarios with varying price regulations concerning prices for fuel, CO2, electricity, and public transport. Given the reported mobility tools and supported by live calculation of resulting cost changes, respondents were asked to adapt their household fleet while being allowed to choose the mobility tools at a high level of detail. Results of a multinomial logit model show that increasing fuel prices, very low electricity prices, high EV subsidies and low public transport prices have the potential to decarbonize household fleets (remove conventional vehicles and/or replace by an electric vehicle).
