Moving west or going south? Economic transformation and institutionalization in postcommunist party systems

Patterns of party system institutionalization have varied widely across regions. In postcommunist democracies, weak party system institutionalization exists at high levels along three dimensions-volatility of representation, party extinction, and incumbency disadvantage-despite sustained economic growth. In these cases, the effects of economic restructuring are critical to electoral outcomes. A sample of democratic elections from 1990 to 2006 shows that postcommunist countries whose reform strategies minimize increases in inequality have more institutionalized party systems.
