Party System Polarisation and Government Duration in Central and Eastern Europe

Abstract:

Since the transition to democracy in the early 1990s, more than 60 per cent of governments in Central and Eastern Europe have terminated prematurely. This article argues that the character of party system development in the region has facilitated the emergence of a polarised pattern of party competition and that competition for government now takes place in distinct ideological blocs. Parties seek to form governments within these blocs but not across them and therefore there is little incentive to defect from a governing coalition due to the lack of viable alternatives. As a result, more polarised party systems produce more durable governments. The empirical evidence shows that polarisation and ideological diversity of the government are significant indicators of government duration in Central and Eastern Europe. Ideologically compact governments formed within narrow blocs in the party system survive longer than ideologically diverse coalitions that emerge from less polarised party systems.
