Abstract
Abstract The article criticises current conceptual frameworks focused on the evaluation of the performance of electoral systems. It offers a new tool allowing researchers to measure the size of the deviation of electoral outcomes from theoretical expectations. The index d=log[NS/(MS)1/6] is built on the Seat Product (Taagepera, Rein (2007b) Predicting Party Sizes: The Logic of Simple Electoral Systems. New York: Oxford University Press) and captures the deviations of electoral outcomes from predictions solely on the basis of two institutional factors – average district magnitude (M) and size of assembly (S). The theoretical background of index d is explained, and its reliability is further supported by conventional econometric methods based on empirical data.
期刊介绍:
World Political Science (WPS) publishes translations of prize-winning articles nominated by prominent national political science associations and journals around the world. Scholars in a field as international as political science need to know about important political research produced outside the English-speaking world. Sponsored by the International Political Science Association (IPSA), the premiere global political science organization with membership from national assoications 50 countries worldwide WPS gathers together and translates an ever-increasing number of countries'' best political science articles, bridging the language barriers that have made this cutting-edge research inaccessible up to now. Articles in the World Political Science cover a wide range of subjects of interest to readers concerned with the systematic analysis of political issues facing national, sub-national and international governments and societies. Fields include Comparative Politics, International Relations, Political Sociology, Political Theory, Political Economy, and Public Administration and Policy. Anyone interested in the central issues of the day, whether they are students, policy makers, or other citizens, will benefit from greater familiarity with debates about the nature and solutions to social, economic and political problems carried on in non-English language forums.
