The POVB November newsletter shared a short quote from the committee which motivated the decision:

“The prize committee, composed of Marina Costa Lobo (University of Lisbon), Eelco Harteveld (University of Amsterdam) and Romain Lachat (SciencesPo Paris) is pleased to award the ECPR Standing Group on Public Opinion and Voting Behaviour in a Comparative Perspective prize for the best paper presented at the 2022 ECPR General Conference to Maurits Meijers, Björn Bremer, Theresa Kuhn and Francesco Nicoli for their paper “Partisan Cueing and Preferences for International Cooperation”.

In this paper, Meijers et al. present the results of pre-registered survey experiments in five countries to examine the effects of party cues on respondents’ positions on joint European debt. This paper contributes to the literature on partisan cue effects and pushes it further by theorising the role of both in- and out-party cues. The experimental design is well-thought out, and the analyses are presented with great care and nuance. The paper’s findings are important for EU politics too, as they show that parties have quite some leeway to structure support for measures that foster international cooperation.”
