Rationalist Theories of Politics: A Midterm Report
Published online by Cambridge University Press: 13 June 2011
Abstract
Rational-choice theories of politics have gained acceptance rapidly and may soon dominate the field. Their popularity is due in part to their real successes, which can be demonstrated in several areas, and to their hypothetical-deductive structure. But some students, in their eagerness to embrace what is by now a theoretical fad, have either ignored inconvenient facts or weakened the theory to fit them. Both the promise and the risk are demonstrated by reference to recent works by Mayhew, Niskanen, Rabushka and Shepsle, and de Swaan.

The influence of these two theories is suggested not only by the copious references to their original proponents, but by the dominant position in the discipline of areas of research that derive from them: political socialization; political values, norms, orientations; the performance and responsiveness of political systems; deprivation and its political consequences.

To identify rationalism with “the economic approach” is, however, misleading: nearly all economics is rationalist, but not all rationalist work is economic. See beolw, p. 303.

15 Since the identical point was made rather emphatically by Downs (fn. 7), 37, almost twenty years ago, I see little excuse for the confusion that still widely prevails.

39 In particular, political analysts of the earlier period tended to consider American society and politics synonymous with “modern”, “developed”, or “democratic” forms: e.g., Gabriel Almond's lyrical treatment of “Anglo-American” political culture in his seminal “Comparative Political Systems” (fn. 5), esp. 398–400, or Dahl's, Robert A. ode to the “American Hybrid” in A Preface to Democratic Theory (Chicago and London: University of Chicago Press 1956)Google Scholar, chap. 5.

47 The difference between the questions that one would have expected to result from Almond's article on “Comparative Political Systems” (1956) and the ones that were actually asked in The Civic Culture (1961) was already instructive; but, for an extreme case of the subsequent eclecticism, see Rose, Richard, “England: The Traditionally Modern Political Culture”, in Pye, Lucian W. and Verba, Sidney, eds., Political Culture and Political Development (Princeton: Princeton University Press 1965)Google Scholar, chap. 3.
48 The criticisms of Schonfeld, William R., “The Focus of Political Socialization Research: An Evaluation”, World Politics, XXIII (April 1971), 544–78CrossRefGoogle Scholar, are particularly cogent.

50 A bureau could of course seek the maximum demand point nonetheless by deliberate underbidding: i.e., asserting to the funding agency that the cost would be lower, and later seeking a deficiency appropriation or supplying less than was promised. Niskanen argues, however, that such breaches of credibility are rather sternly punished by most funding agencies and that bureaucrats have many incentives to remain honest in this respect (p. 42).
51 Cited in Niskanen, 71.
52 Niskanen's ideology blinds him here to a point that one would think congenial to a conservative, namely an explanation of what for convenience may be called the “Rockefeller effect” on state and local spending. Niskanen shows, in an elegant theoretical chapter (chap. 12), that a bureaucrat who expects to be in office only briefly is likely to push immediate costs even higher. Surely it would follow that, where governorships and mayoralties serve as springboards toward national office, state and local spending would tend to rise. But perhaps this is a point on which a former adviser to Governor Reagan is not inclined to dwell.
53 Each newly elected parliament constitutes a new “situation”; in addition, each substantial shift of seats or of partisan affiliations within an existing parliament—e.g., the successive splits of the Gaullist RPF in the Second Assembly of the Fourth Republic—is taken to create a new “situation.” See, for example, de Swaan, 187–89.
54 The countries are: the German Weimar Republic, the French Fourth Republic, postwar Italy, the Netherlands, Israel, Finland, Sweden, Denmark, and Norway. Periods in which the given country or regime did not exist or was under foreign occupation are, of course, excluded.

57 Axelrod's hypothesis asserts, in essence, that only those coalitions will form which: (a) are winning (i.e., have a majority); (b) are connected, or closed, in the sense of consisting only of parties adjacent to one another on the ideological spectrum, with no “leaps” or “gaps”; and (c) are minimal, in the sense of including no unnecessary parties at either their left or their right extremes.

59 A perhaps extreme case is the Lyng government in Norway, which held office for four weeks in 1963. It is weighted equally with the Gerhardsen government, which held power for all of the rest of that parliament's four-year term (1961–1965). See de Swaan, 281.

63 The crucial British legislation was the Corrupt Practices Act of 1883, which sharply curtailed expenditures by individual candidates but left unregulated those by national party organizations; see, for example, Hanham, H. J., Elections and Party Management: Politics in the Time of Disraeli and Gladstone (London: Longmans, Green 1959)Google Scholar, esp. chaps. 12 and 17. In the United States, the Legislative Reorganization Act of 1946 greatly expanded the resources of the individual representative; see Huntington, Samuel P., “Congressional Responses to the Twentieth Century,” in Truman, David B., ed., The Congress and America's Future (Englewood Cliffs, N.J.: Prentice-Hall 1965), 5–31, at 20–21.Google Scholar
64 Sharply curtailing individual candidates' expenditures (on the British model), while permitting or even subsidizing the involvement of central party organizations in primary elections, would pretty clearly give the parties the whip hand in the selection of candidates.
65 To say that of course politicians would never act against their own interest in this way is too easy: they have so acted, for example in Britain in 1883; and we may be supposing their self-interest to be narrower than it is.

89 Security in office is, of course, not adequately measured by the partisan competitiveness of districts, or even by the numbers of successful primary challenges. We must ask, rather, how frequent and how geographically widespread both bipartisan competition and serious challenges for the nomination—in which, say, the challenger gains as much as two-thirds of the vote obtained by the incumbent, or 40 percent in a twoway race—have been at various times. I know of no good longitudinal figures on this, but I doubt that many representatives today can feel as secure as some of the Southern Congressional monoliths once did.
70 The fallacy is nicely elucidated in Davis (fn. 23), 55–57.

75 It is more difficult to test, but in principle probably more testable. An adequate test of many of the central hypotheses of Buchanan and Tullock's Calculus of Consent or Rawls's Theory of Justice, for example, would demand evidence that we do not now have and that would be costly to acquire; if acquired, however, it would be conclusive.
