Identifying a crisis for representative democracy in Western European party systems, this essential book studies the widening gap between political parties' ideological economic Left-Right rhetoric and their increasing convergence on policymaking. Addressing whether these ideologies are converging or diverging, it answers whether these changes are initiated by the parties themselves, aligned with voter demand, or forced by economic globalization. The crisis of representative democracy in Western Europe is a prevalent issue in comparative politics. This comprehensive study assesses the problems faced by representative democracy by analysing ideological polarization and inter-party conflict in relation to the changing linkage between citizens, parties, and public policies, and the implications this has for representative democracy. Considering both supply-side and demand-side theories, it analyses five major theoretical themes central to the ideological convergence and polarization within party systems, including the cartel party thesis, the median voter theorem, realignment theory, consensus democracy theory, and globalization theory. Going beyond theory, chapters use five decades of empirical research to present new and unique longitudinal and comparative data sets covering eight party systems, ultimately providing a more accurate diagnosis of the vitality of representative democracy in contemporary Western Europe. Combining in-depth theoretical analysis with empirical research, this comprehensive book will prove invaluable to students and scholars of politics and political science, and policymakers concerned with party systems.

It is often suggested that political parties are becoming increasingly alike, and that party politics has turned into an elite affair where political professionals collude to further their self-interest rather than work to represent the interests of their constituents. In recent decades this diagnosis has been famously associated with Richard Katz and Peter Mair's cartel party theory. Yet so far this controversial thesis has not been subjected to systematic empirical scrutiny, nor has its conceptual and normative underpinnings been properly considered. In this volume a group of political scientists with different specialisations take on this task, focusing empirically on the Swedish party system, which the originators of the cartel party theory have suggested is especially conducive to the formation of party cartels. Collecting new and unique qualitative and quantitative data, the volume casts serious doubt on the validity of the cartel party theory as an explanation for party system change.
