Gordon Tullock, on the other hand, might be characterized as the somewhat cynical pragmatist, who set out to understand the world, not to change it. This side of Tullock is visible in his early paper on simple majority rule, and is perhaps most apparent in his work on rent seeking. These differences should not be pushed too far, however. Buchanan also contributed to the rent-seeking literature, and often has described public choice as “politics without romance.” One of the most dispiriting contributions to the public choice literature has to be Kenneth Arrow’s famous impossibility theorem. In a too little appreciated article, Tullock demonstrated with the help of a somewhat torturous geometrical analysis, that the cycling that underlies the impossibility theorem is likely to be constrained to a rather small subset of Pareto-optimal outcomes, and thus Arrow’s theorem was “irrelevant,” a rather happy result, and one which anticipated work appearing more than a decade later on the uncovered set. In Chap. 10 of Toward a Mathematics of Politics, Tullock engages in a bit of wishful thinking about constitutional design by describing how one could achieve an ideal form of proportional representation in a legislative body. He also was an early enthusiast of the potential for using a demand-revelation process to reveal individual preferences for public goods . (en) |
