What difference does the framing of a crisis make to European Union solidarity?

Does the framing of crises shape public support for inter-state solidarity? We focus on three dimensions that have been salient in the characterisation of European Union crises and may affect public support for solidarity more generally: (a) how country-specific or common a crisis is; (b) whether policymakers are seen as responsible for the crisis or not; and (c) how existential or manageable the threat posed by a crisis appears. We employ a pre-registered factorial vignette experiment conducted in 15 European Union countries to assess how characterising a hypothetical crisis affects voter support for fiscal and financial solidarity. Our results show that exposure to different crises frames shapes public support for risk-sharing in the European Union. Changes in solidaristic attitudes vary significantly with the means of fiscal risk-sharing proposed.
