Dimensions of democracies

Abstract The conventional wisdom concerning the choice between majoritarian electoral systems and proportional representation (PR) - and, more broadly, between majoritarian and consensus forms of democracy - is that there is a trade-off: PR and consensus democracy provide more accurate representation and better minority representation, but majoritarianism provides more effective government. A comparative analysis of 18 older and well-established democracies, most of which are European democracies, shows that PR and consensus democracy indeed give superior political representation, but that majoritarian systems do not perform better in maintaining public order and managing the economy, and hence that the over-all performance of consensus democracy is superior. This conclusion should also be tested among the growing number of slightly newer non-European democracies, which are already old enough to have proved their viability and can be studied over an extended period of time. If its validity is confirmed - and the evidence so far is very promising -it can have great practical significance for the future of democracy in the world.
