On the strategic inconsistency of the meta-rights approach

Among many attempts to circumvent Sen's impossibility result Gibbard's theory of alienable rights has attracted attention of many researchers. Basu's (1984) theorem essentially depends on a Nash-type equilibrium concept. In this paper we introduce an alternative behavioral assumption where individuals have conjectures about the responses of others and investigate the robustness of Basu's result under this new solution concept. We also examine a possibility of coalition formation and cooperation under the meta-rights approach.For helpful discussions I would like to thank Rajat Deb, Joseph Greenberg, and Shlomo Weber. I am also indebted to an anonymous referee of this Journal for many valuable comments.     

Power,luck and the right index

Summary We have pointed out the theoretical drawbacks of the traditional indices for measuring a priori voting power inasmuch as they are implied in considering the coalition value a private good. This criticism caused us to view the coalition outcome as a public good. From this aspect and additional considerations with respect to power, luck, and decisiveness, we obtained a story describing the characteristics of an adequate measure of a priori voting power. These characteristics were found to be fulfilled by an index presented by Holler (1978). Through the above analysis this index has received its theoretical justification. An independent view of this index was then provided by means of an axiomatic characterization. This characterization makes possible abstract comparison of the index with previously established private good indices.While we have restricted our attention to simple games, the index presented can be generalized to provide a value on games in characteristic function form. We leave this topic for future conideration.     

Individual Decision Making in a Negative Externality Experiment

The experimental treatments analysed in this paper are simple in that there is a unique Nash equilibrium resulting in each player having a dominant strategy. However, the data show quite clearly that subjects do not always choose this strategy. In fact, when this dominant strategy is not a focal outcome it does not even describe the average decision adequately. It is shown that average individual decisions are best described by a decision error model based on a censored distribution as opposed to the truncated regression model which is typically used in similar studies. Moreover it is shown that in the treatments where the dominant strategy is not focal dynamics are important with average subject decisions initially corresponding to the focal outcome and then adjusting towards the Nash prediction. Overall, 66.7% of subjects are consistent with Payoff Maximization, 27.8% are consistent with an alternate preference maximization and 5.6% are random.

Convention, Social Order, and the Two Coordinations

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.     

The evolution of conventions under incomplete information

Summary. We formulate an evolutionary learning process with trembles for static games of incomplete information. For many games, if the amount of trembling is small, play will be in accordance with the games (strict) Bayesian equilibria most of the time. This supports the notion of Bayesian equilibrium. Often the process will select a specific equilibrium. We study an extension to incomplete information of the prototype conflict known as Chicken and find that the equilibrium selection by evolutionary learning may well be in favor of inefficient Bayesian equilibria where some types of players fail to coordinate.Received: 17 March 2003, Revised: 3 December 2003, JEL Classification Numbers: C72.     

A New Variant of the Winner's Curse in a Coasian Contracting Game

We examine behavior in a Coasian contracting game with incomplete information. Experimental subjects propose contracts, while automaton property right holders or robot players with uncertain preferences respond to those proposals. The most common pattern of proposals observed in these games results in too many agreements and, in some games, payoffs that are stochastically dominated by those resulting from rational proposals (which imply fewer agreements). In this sense, we observe a winner's curse similar to that observed in bidding games under incomplete information, such as the common value auction (Kagel, J.H. and Levin, D. (1986) American Economic Review. 76, 894–920) and the takeover game (Samuelson, W. and Bazerman, M.H. (1985) In Research in Experimental Economics, Vol. 3. JAI Press, Greenwich, pp. 105–137; Ball, S.B., Bazerman, M.H., and Carroll, J.S. (1990) Organizational Behavior and Human Decision Processes. 48, 1–22; Holt, C. and Sherman, R. (1994) American Economic Review. 84, 642–652). While the naïve model of behavior nicely predicts the winner's curse in those previous bidding games, it does not do so here. Instead, an alternative model we call the guarantor model explains the anomalous behavior best. Hence, we suggest this is a new variant of the winner's curse.     

A theory of codetermination

Summary and conclusions This paper has developed a framework of theory within which codetermination, collective bargaining, individual bargaining, and workers' management may be compared. This has required a rather long digression on the theory of labor contracts in general when effort is endogenous but is wholly specified by the contract (section II) and when effort is multidimensional and labor contracts are incomplete (section III). When labor contracts are incomplete, suboptimization behavior results, and this in turn implies inefficiency. The inefficiency is displayed in a maximization problem by a structure which formally resembles the Lipsey-Lancaster second-best solution. Codetermination permits improved efficiency by creating a context of joint management decision in which some of the free variables may be jointly determined, with the result that some second-best constraints are relaxed. Thus the theory allows a possibility that power-sharing can in itself shift the effort-productivity frontier outward. This is an empirical question, of course, but one which is excluded from consideration by theories in the neoclassical and Illyrian tradition which are based on homogenous labor and complete labor contracts. Thus, the theory set forth here should supplant the less general neoclassical and Illyrian hypotheses unless and until evidence is offered which supports those hypotheses.The author is indebted to an anonymous referee for several suggestions which improved the paper, to W. Lynn Holmes and Paul Rappoport of Temple University and to Samuel Shrager of Temple University and Vilanova University for clarifying discussions on several aspects of the paper.

On the Durability of King and Council: The Continuum Between Dictatorship and Democracy

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.     

From “tax state” to “debt state”

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.     

On designing economic agents that behave like human agents

This paper explores the idea of constructing theoretical economic agents that behave like actual human agents and using them in neoclassical economic models. It does this in a repeated-choice setting by postulating artificial agents who use a learning algorithm calibrated against human learning data from psychological experiments. The resulting calibrated algorithm appears to replicate human learning behavior to a high degree and reproduces several stylized facts of learning. It can therefore be used to replace the idealized, perfectly rational agents in appropriate neoclassical models with calibrated agents that represent actual human behavior. The paper discusses the possibilities of using the algorithm to represent human learning in normal-form stage games and in more general neoclassical models in economics. It explores the likelihood of convergence to long-run optimality and to Nash behavior, and the characteristic learning time implicit in human adaptation in the economy.     

Land use, biodiversity, and sustainability

We focus on the effects of deforestation for agricultural purposes on biodiversity. This topic has been dealt with in the recent literature where forested land and biodiversity are treated as synonyms. In contrast to that, this paper distinguishes between forested land and forest itself, the latter being interpreted as a measure of biodiversity. The regenerative capacity of forests is modeled as a function of the own stock and of the habitat size. In particular, the threat of a given minimum viable population to be achieved in the course of the reduction of habitats is taken into account. The corresponding structure of a sustainability indicator is elaborated.     

Fully endogenous mechanism selection on finite outcome sets

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.

On the theory of cost sharing

This paper investigates efficiency and equitability issues given a cost sharing method in an economy with a public commodity. We study the concept of a -cost share equilibrium and examine the set of all equilibrium allocations. Finally, we devise a mechanism to implement -cost share equilibria as strong equilibria of an associated non-cooperative game.This paper was written while Shlomo Weber was visiting the University of Bonn.

The Question of “Equilibrium” in Human Action and the Everyday Paradox of Rationality

This paper first specifies how Schütz's analysis of deliberation determines the limits of rationality where individual human action is concerned. This analysis establishes that there is no equilibrium of alternative possibilities before or after deliberation. Next the paper specifies how Schütz's analysis of the typification that makes successful intersubjective action possible leads to the paradox of rationality on the common sense level. Finally, the paper explains how Schütz's analysis of relevance can provide an account for this paradox, and thereby point to an order of human interaction in the absence of equilibrium, all without violating the postulate of subjective interpretation.

Constitutional “Rules” and Intergenerational Fiscal Policy

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.     

Entropic irreversibility and uncontrolled technological change in economy and environment

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.

The allocation of ideological structures

This article tries to make allocation in the sociology of knowledge more teachable. What may appear as a sectarian magic is transformed into a rational procedure to be used by teacher and student alike. Allocation requires a number of steps by which (1) the ideological structure is made part of an ideology; and (2) the ideology is related to a particular social situation of past or present either by reflecting it in symbolic expression or by reflecting the exact opposite.The old puzzle of how ideological relativism can be asserted from a theoretical position, which — by social background — cannot be anything but relative in itself, falls by the wayside. Temporarily positivism is claimed for any viewpoint which allows empirical verification. It asserts its relativisim but never reaches absolute and final truth. Relative advantages only can be claimed for the many comprehensive social theories at any given time.The term imputation is replaced by the term allocation in this article. Imputation is a direct translation of the German word Zurechnumg. Borrowed from economic theory, this term is unnecessarily complicated. We cannot do more than allocated ideologies in a manner not amenable to precise numerical imputation.     

Learning for Innovation and the Skill Premium

The computer revolution took very long to pay off in productivity growth in the computer-using sectors. The relative wage of skilled workers, however, has risen sharply from the early days of the computer revolution onward. As skilled workers wages reflect their productivity, the two observations together pose a puzzle.This paper provides a micro-based explanation for the long diffusion period of the computer revolution. The general equilibrium model of growth zooms in on the research process and provides an explanation for sluggish growth with booming relative wages of the skilled. Technological progress in firms is driven by research aimed at improving the production technology (innovation) and by assimilation of ideas or principles present outside the firm (learning). A new General Purpose Technology (GPT) like the computer revolution generates an initial slowdown in economic growth and an increase in the skill premium.Acknowledgement I am indebted to Theo van de Klundert for suggestions and encouragement.
