Position, selective emphasis and framing: How parties deal with a second dimension in competition

This Special Issue aims to (1) theorise party strategies in multi-dimensional policy spaces; and (2) apply the theory to party competition in multinational democracies characterised by a salient territorial dimension alongside a more established economic dimension. The introductory article brings together recent contributions treating spatial and salience theories as compatible and policy spaces as two-dimensional to propose four party strategies that can be ranked from one- to two- dimensional competitive behaviour: uni-dimensionality, blurring, subsuming, and two- dimensionality. The remaining contributions operationalise these strategies and draw on a variety of data sources ranging from manifestos to parliamentary bill proposals and expert surveys to describe when and explore why parties use these strategies in competition focusing on patterns of party competition in multinational democracies, selected as typical cases of multi-dimensional competition.
