William Riker is one of the most influential political scientists at present writing on the theory and practice of democracy. A quick count on my part of the Social Science Citation Index, normally a Siva of academic reputations, revealed nearly one thousand entries under Riker's name between 1971 and the beginning of 1982. Not only is his work frequently cited, it is read long after it is originally published. The Theory of Political Coalitions, probably his best known work, was published in 1962, and is still seriously discussed by those engaged in the empirical study of political coalitions. Moreover, Riker has always been anxious to show the relevance of technical work in political science to the political philosophy of democracy. His work therefore represents not simply an impressive scholarly and academic achievement, but also an important contribution to the more wide-ranging public debate about the nature and value of democracy.

16 Riker does pay some attention to the relative costs of forming different coalitions by introducing the idea of ‘side-payments’ which the members of a proto-coalition may offer to outsiders to induce them to join. Some aspects of ideological compatibility or incompatibility might be captured through the use of this idea – for instance where a side-payment takes the form of a promise to modify one's legislative programme. This is a less demanding way for ideological considerations to enter a theory of coalition formation than would be true of those theories in which ideological similarity is explicitly required.

17 I have constructed my interpretation of the argument from The Theory of Political Coalitions, Chap. 2 and Appendix 1, and from Riker, William H. and Ordeshook, Peter C., An Introduction to Positive Political Theory (Englewood Cliffs, N.J.: Prentice-Hall, 1973)Google Scholar, Chap. 7.1 advise the interested reader who is new to Riker's theory to begin with Chap. 2 of The Theory of Political Coalitions, then to go to Positive Political Theory and then back to the appendix of the former work.
