MTI Distinguished Seminar Series: Gianluca Trotta

The MTI Distinguished Seminar Series welcomed Gianluca Trotta, senior energy economost at COWI, on May 6 for talk entitled "The Effect of Changing Registration Taxes on Electric Vehicle Adoption: Evidence from Denmark."

As Denmark makes the transition to a low-carbon economy, large-scale deployment of battery electric vehicles (BEVs) is a key part of the equation.. The country has traditionally stimulated use of BEVs through a registration tax exemption that was lifted in 2016 and partially re-introduced in 2018. Exploiting car registration as well as detailed population data covering the period 2013-2019 and using Bayesian additive regression trees (BART), Trotta has obtained new empirical evidence on the effects of the registration tax evolution on the adoption of BEVs in Denmark and the socioeconomic factors that influence BEV adoption.

The results suggest that the number of BEVs would have been higher if the tax exemption had remained. Moreover, Trotta's study detected heterogeneous treatment effects that are larger the more likely a socio-economic group is to purchase a BEV. Consequently, it found substantial freerider effects in the promotion of BEVs via the tax system.
