Constitutional “Rules” and Intergenerational Fiscal Policy   总被引:1,自引:1,他引:0  
This paper analyzes the impact of alternative political institutions on sustainable fiscal policies. We study the choice of intergenerational transfers as outcomes of an infinite social security game among successive selfish median voters. Majoritarian systems accord the current median voter maximum fiscal discretion but no direct influence over future policy. This political arrangement sustains, among others, dynamically inefficient transfers and volatile, non-stationary sequences. Constitutional rules award to the minorities veto power over fiscal policy changes proposed by the majority. This unanimity provision is equivalent to partial precommitment. Under constitutional rules, sustainable fiscal policies feature Pareto efficient, non decreasing transfer sequences.  相似文献

Collective action can take place at a plurality of levels. It has to be based on a constitution which defines the basic rules of interaction. Here, we are concerned with the problem of the constitutional setting of bottom-up formal institutions with a club nature. The pressure to improve the efficiency of services pushes local administrations to co-ordinate to produce public goods. This process has stimulated the birth of different forms of agencies or private companies with a club nature. The aim of this paper is to discuss the effects of institutional interdependence on the efficiency of this kind of collective action. In order to shed some light on this problem, the paper first discusses the problem of the relativity of efficiency to the institutional setting. A framework of analysis is then discussed to identify the main factors affecting collective action. Finally some evidence will be provided by a comparative institutional analysis performed on some case studies concerning local associational forms among communes in north-eastern Italy.  相似文献

Convention, Social Order, and the Two Coordinations   总被引:2,自引:0,他引:2  
The word coordination has two meanings, and thesemeanings are often conflated. One meaning, associated with ThomasSchelling, is seen in situations like choosing whether to driveon the left or the right; the drivers must coordinate to eachother's behavior. The other meaning, associated with FriedrichHayek, means that a concatenation of activities is arranged soas to produce good results. Along with the Schelling sense ofcoordination comes the notion of convention, such as drivingon the right. Some conventions are consciously designed; othersemerge without design (or are emergent). Along with the Hayeksense of coordination comes the notion of social order. Somesocial orders, such as the skeleton of activities within thefirm or within the hypothetical socialist economy, are consciouslyplanned. Other social orders, such as the catallaxy of the freesociety, function without central planning (or are spontaneous).Distinguishing between the two coordinations (and, in parallelfashion, between convention and social order) clarifies thinkingand resolves some confusions that have arisen in discussionsof coordination and spontaneous order. The key distinctionsare discussed in the context of the thought of, on the one hand,Menger, Schelling, David Lewis, and the recent path-dependencetheorists, and, on the other hand, Smith, Hayek, Polanyi, Coase,and the modern Austrian economists. The paper concludes witha typology that encompasses the several distinctions.  相似文献

A social-welfare (illfare) function framework is applied to compare two demographic groups as to the severity of their unemployment experience. This is based on the assumption that for each individual the disutility of unemployment is an increasing and convex function of spell length. The very concept of spell length and its distribution, however, is not unambiguous. In contrast to previous literature which focuses exclusively on the interrupted spell length in a stock of unemployed, we stress the usefulness of the concept of complete spell length in a cohort of unemployed. We establish an equivalence relationship between second-degree dominance in the cohort and first-degree dominance in the stock. For specific illfare functions the disutilityU(x) when applied to the cohort and the disutilityU(x) when applied to the stock will produce the same value of aggregate welfare (illfare).  相似文献

Conclusion When this research was started, it was guessed that the Dorfman-Steiner rule would lose its relevance in an intertemporal setting. This belief has turned out to be false: along the optimal paths ofp (t) ands (t), and must be equal. The only difference with the Dorfman-Steiner result is that they will be different from unity.The author is chargé de cours at the Faculté Universitaire Catholique de Mons (Belgium).

The paper is motivated by Joseph A. Schumpeter's The Crisis of the Tax State. It inquires whether the buildup of government debt in peacetimeprosperity is a threat to the stability, existence or creation of viable tax states. The paper begins by setting out Schumpeter's conception of the tax state and the nature of recent political-economic events which have reinvigorated the concept. Next the paper sets out some simple debt dynamics and sketches a debt-induced business cycle arising from heavy reliance on debt finance in peacetimeprosperity. Finally, the paper assesses threats to the tax state in light of recent work on path dependence and positive feedback. An attempt is made to throw some light on whether the plethora of new, and often small, states spawned by the demise of communism can be viable tax states.Essay on Government, the Tax State and Economic Dynamics submitted to the Third Schumpeter Prize Competition.  相似文献

In practice one rarely observes pure forms of dictatorship that lack a council, or pure forms of parliament that lack an executive. Generally government policies emerge from organizations that combine an executive branch of government, the king, with a cabinet or parliamentary branch, the council. This paper provides an explanation for this regularity, and also provides an evolutionary model of the emergence of democracy that does not require a revolution. The analysis demonstrates that the bipolar king and council constitutional template has a number of properties that gives it great practical efficiency as a method of information processing and as a very flexible institutional arrangement for making collective decisions.  相似文献

For infinite-horizon optimal-growth problems the standard result in the literature says that a program is optimal if and only if associated with it is a sequence of present-value prices at which the program satisfies (i) a set of myopic competitive conditions, and (ii) an asymptotic transversality condition. The principal result of this paper points out the interesting and surprising fact that at least for a class of multisector models where the production side is described by a simple linear model, and there are some limiting primary factors, the competitive conditions alone characterize an optimal program.  相似文献

This paper investigates the welfare effects of unilateral or multilateral technological progress in a world with global public goods. We focus on the consumption relation between the private and the public good, and then show that technological progress may beself-centered (benefit oneself but harm others), self-sacrificing (harm oneself but benefit others), or self-defeating (harm all) if two goods are substitutable. In addition, any type of technological progress improves every countrys welfare if the private and the public good are close complements.  相似文献

Summary. We present a new class of rules named augmented serial rules for the provision of an excludable public good. First, we characterize this class by the four axioms of strategy-proofness, envy-freeness, access independence, and nonbossiness. Second, we identify two important subclasses by imposing an additional axiom: (i) anonymous augmented serial rules by anonymity, and (ii) Moulins serial rule by individual rationality.Received: 31 December 2002, Revised: 9 June 2004, JEL Classification Numbers: D71, D82, H41.This paper is a substantial revision of Serial cost sharing with simple games.

This paper continues the discussion of artificial worlds (AWs) begun in Lane (1993b). Here, the focus is on two kinds of AWs. The first, classifier systems, can be used to represent agents that are capable of generating complex behaviors in response to intermittent rewards from an environment of which they are a part. A collection of such agents, engaging in economic interactions with one another, produces another kind of AW, in which such interesting aggregate behaviors as the formation of bubbles and crashes and technical trading in an artificial stock market, may arise. The second kind of AW considered in this paper is artificial economies. These AWs can provide a dynamic, nonequilibrium, microfounded account of such aggregate-level or macroeconomic phenomena as stable growth paths, business cycles, and Pareto firm-size distributions.  相似文献

In this paper, I consider the influence of political competition on opinion. After reflecting on the notion opinion as a concept in the economic analysis of politics, I turn to Hayek's Constitution of Liberty and consider his argument for democracy on the grounds that it is the form of government which best promotes progress in opinion. Yet Hayek's claim that democratically formed opinion improves is unsubstantiated. I turn to accounts of expressive voting thereafter to show why opinions which are realised in the form of votes may be anything other than propitious to democratic culture. I then return to Hayek and consider what becomes of opinion in Law, Legislation and Liberty. His claim that opinion improves under democratic institutions is no longer of great significance to him. Indeed, his account of the rise of bargaining politics provides evidence against the claim that opinion improves. I conclude by asking how democracy can be shielded from opinion, that is, how opinion might be improved in ways which go beyond Hayek's model of political competition outlined in Constitution of Liberty. To this end, I look to accounts of deliberative democracy and expressive politics for support.  相似文献

Summary We consider both Nash and strong Nash implementation of various matching rules for college admissions problems. We show that all such rules are supersolutions of the stable rule. Among these rules the lower bound stable rule is implementable in both senses. The upper bound Pareto and individually rational rule is strong Nash implementable yet it is not Nash implementable. Two corollaries of interest are the stable rule is the minimal (Nash or strong Nash) implementable solution that is Pareto optimal and individually rational, and the stable rule is the minimal (Nash or strong Nash) implementable extension of any of its subsolutions.We wish to thank Professor William Thomson for his efforts in supervision as well as his useful suggestions. We are grateful to the participants in his reading class, workshops at Bilkent University, University of Rochester, and in particular Jeffrey Banks, Stephen Ching, Bhaskar Dutta, Rangarajan Sundaram and an anonymous referee for their helpful comments.  相似文献

A joint production model representing Spaceship Earth is used to explore at a conceptual level, implications of natural resource depletion and economic waste production for economy-environment change. Ecological change is considered as uncontrolled technological innovation, partially induced through disposal of unwanted surpluses (by-products and wastes from economic activity). These surpluses may accumulate as wastelands, or (more likely) contribute to uncontrolled ecological change. Technologically stationary economy-environment steady-state solutions are contrasted with instability and forced change where either the technologies or the patterns of resource allocation in economic and environmental processes are incompatible with a steady state.Thanks to Charles Perrings, Louis Arnoux, and three anonymous referees. Responsbility for any errors or obscurities in argument is mine alone.  相似文献

Summary This paper defines a choice process over social outcomes in which agents choose the institutional rules ormechanisms themselves without outside interference. Truly endogenizing the mechanism selection process in this way, however, involves facing an infinite regress problem in which outcomes are chosen by games which are themselves chosen by games, ad infinitum. This paper allows the possibility of such an infinite regress which we callfully endogenous mechanism selection.We introduce the notion ofFree Choice which restricts the class of mechanisms in the regress to those which prevent agents from being locked in to an equilibrium outcome by the actions of others. Under this condition, the infinite regress is shown to get truncated with the number of selection iterations endogenously determined. It turns out that the outcomes resulting from a Free Choice-constrained regress are (Weakly) Pareto optimal; in particular, these outcomes solve a weighted Rawlsian Maxmin criterion. We also show that these outcomes are invariant to the equilibrium concept used to evaluate games in the regress.This paper is based on the author's dissertation from the University of Minnesota (November, 1989).I am very grateful for the guidance, advice, and encouragement from my advisor, Marcel K. Richter, and for the many helpful suggestions from David Levine. I have also benefited from conversations with Nabil Al-Najjar, Gerhard Glomm, Leonid Hurwicz, James Jordan, Ramon Marimon, Andrew McClennan, Ariel Rubinstein, and William Thomson.  相似文献

There is a sharp disagreement between mainstream economists and advocates of energy efficiency as regards the potential for free lunches or no regrets policies to cut greenhouse gas emissions. From an economics perspective, the critical question is whether the economic system is — or is not — close to a Pareto-optimum equilibrium state. If so, it follows that most technological systems now in place are optimum, or nearly so, from an economic perspective. If not, there may be many sub-optimal technologies in place, with corresponding opportunities for very high returns on appropriate investments. This paper presents some of the evidence supporting the latter thesis.  相似文献
