This bold venture into political theory and comparative politics combines traditional concerns about democracy with modern analytical methods. It asks how contemporary democracies work, an essential stage in asking how they can be justified. An answer to both questions is found in the idea of the median mandate. The voter in the middle - the voice of the majority - empowers the centre party in parliament to translate his or her preferences into public policy. The median mandate provides a unified theory of democracy - pluralist, consensus, majoritarian, liberal, and populist - by replacing each qualified 'vision' with an integrated account of how representative institutions work. The unified theory is put to the test with comprehensive cross-national evidence covering 21 democracies from 1950 through to 1995. This exciting book will be of interest to specialists and general readers alike, representing as it does a reaffirmation of traditional democratic practice in an uncertain and threatening world. Comparative Politics is a series for students and teachers of political science that deals with contemporary government and politics. The General Editors are Max Kaase, Professor of Political Science, Vice President and Dean, School of Humanities and Social Science, International University, Bremen, Germany; and Kenneth Newton, Professor of Comparative Politics, University of Southampton. The series is published in association with the European Consortium for Political Research.

This book is probably the most important source of evidence published up to now on the consolidation of democracy in Eastern Europe. It provides estimates of party positions, voter preferences and government policy from election programmes collected systematically for 51 countries from 1990 onwards. Time-series are presented in the text. This also reports party life histories (essential to over time analyses) and provides updated and newly validated vote statistics. All this information and much more is available on the devoted website described in the book. The final chapter gives instructions on how to access the data on your own computer. For comparative purposes, similar estimates of policy and preferences are given for CEE, OECD and EU countries. These estimates update the prize-winning data set covered in Mapping Policy Preferences: Estimates for Parties, Electors and Governments 1945-1998 - also published by OUP. A must-buy for all commentators, students and analysts of democracy, in Eastern Europe and the world.

The Manifesto data are the only comprehensive set of policy indicators for social, economic and political research. It is thus vital that their quality is established. The purpose of this book is to review methodological issues that have got in the way of straightforwardly using the Manifesto data since our two preceding volumes were published and to resolve them in ways which best serve users and textual analysts in general. The book is thus generally about text-based quantitative analysis with a particular focus on the quality of the CMP-MARPOR data and ways of assessing and using them, In doing so the book goes beyond normal data documentation - essential though that is - to confront the analytic issues faced by users of the data now distributed by MARPOR. It also provides concrete strategies for tackling these at the research level, with examples from the field of political representation. The problems of uncertainty, error, reliability and validity considered here are generic issues for political analysts in any area of research, so the book has an interest extending beyond the Manifesto estimates themselves - in particular to other textual analyses. In addition the book widens the range of applications introduced in our two previous volumes and discusses the extension of the manifesto project database to cover Latin America.
