Despite their potential for urgently needed emission reduction, electric vehicles account for a small fraction of the European vehicle fleet. Large scale deployment of electric vehicles requires considerable investments. While public policies are crucial for leveraging such financing, when ill-designed, they risk being ineffective or might even crowd-out investments. This study sheds light on investors' policy preferences in the e-mobility sector. Based on behavioural finance literature, I propose that various a priori beliefs and investors' country-contexts affect their evaluation of e-mobility policies. The policy preferences of European investors are examined through an adaptive conjoint analysis. The results indicate that policy preferences are dependent on investors' belief in government intervention and the effectiveness of e-mobility technology. Furthermore, the existence of a domestic car manufacturing sector and the size of electric vehicle fleets affect investors' policy evaluations. These behavioural aspects should, therefore, be incorporated into future policymaking processes.
