Party competition in emerging democracies: representation and effectiveness in post-communism and beyond

Competition among political parties is subject to two demands: representation and effectiveness. This poses a dilemma for democratization, as the political opening creates pressures for the representation of long-suppressed voices, but the strain of socio-economic transformation engenders pressures for greater effectiveness in building market economies and democratic polities. How do new democracies cope with this dilemma? This article extends the author's previously published work on party-system institutionalization by focusing explicitly on this problem, including on how electoral reforms affect the distinct pulls of representation and effectiveness. Based on data from eastern European and former Soviet states compared to western European and Latin American experiences during their initial periods of democratization, the evidence shows that the institutionalization of representation and effectiveness in post-communism is more hazardous. Politics in the post-communist region is characterized by numerous contending parties, weak political actors and floating constituencies. Volatility is not only higher in comparison to other regions but continues unabated during successive elections. These conditions contribute to the ‘ineffective representation’ evident in the relatively large share of wasted votes at each election, with significant sectors of the electorate left out from legislative representation. Electoral reforms reflect the twin pressures: changes in formula in the direction of proportional representation favour broader representation, but higher thresholds seeking greater effectiveness make more difficult entry into parliament. The resulting mechanical and strategic effects confirm the expected direction of the reforms, although the contrary pulls towards representation and effectiveness render difficult the stabilization of party competition.
