In The Calculus of Consent, Buchanan and Tullock develop a theory of voting rules in which the optimal rule is determined by minimizing the sum of voters' external and decision costs. Other researchers have extended the Buchanan-Tullock model to include the effects of group size and heterogeneity on external and decision costs and, subsequently, on the optimal voting rule. Despite the prominence of the Buchanan-Tullock model in the constitutional, legal, and public-choice literature, their theory has not (to our knowledge) been tested. In this paper we test the Buchanan-Tullock model by examining the establishment and evolution of voting rules in the European Union. Over the past four decades, the European Union has experienced significant changes in number and heterogeneity, and we interpret the general movement towards, and call for, less inclusive voting rules as support for Buchanan and Tullock's original theory. 相似文献

This paper tries to help bridge the inductive and the deductive traditions in the study of democracy. I identify two empirical patterns, which I call the paradox of conflict and the paradox of decision importance. More conflict ridden societies are both less likely to be democracies, and, when democratic, more likely to be consensual rather than majoritarian. Similarly, important (revolutionary, regime-transforming) decisions are less likely to be democratic but, when democratic, they are more likely to be consensual. I use a decision-cost-minimizing model of democracy to explain those patterns. The model is developed out of the metaphor of institutions as decision producing firms, attempting to maximize quality and minimize cost of those decisions. Its main intellectual source is the transaction cost-minimizing view of organizations but the formalism owes most to Buchanan and Tullock's Calculus of Consent. 相似文献
