Summary This paper gives an empirical reexamination of the Linear-Expenditure-hypothesis for Austria. It starts with a brief theoretical discussion of the principal properties and restrictions of the Linear-Expenditure-System (LES). To obtain empirical estimates of the parameters of the LES two different estimation procedures are applied, i.e. the original method used byStone and a simplified version of the Systems-Least-Squares-approach (following theMarquardt-algorithm). There are no essential differences between these estimates. They all seem plausible and satisfy the theoretical restrictions.Usually the stability (i.e. time-invariance) of the parameters is accepted without proof. Using the Moving-Window-Regression-technique, however, most of the estimates vary significantly in time. To obtain a direct proof of the time-dependence of the parameters the LES is reestimated now including trend-factors. Especially results considering time-dependent marginal-budget-shares are considerably better than the static-model results.The conclusion of this paper is that the static version of the LES does not explain the consumer behaviour in Austria and that much more effort should be spent on the estimation of dynamic demand systems.  相似文献

Summary In this paper we consider Anonymous Sequential Games with Aggregate Uncertainty. We prove existence of equilibrium when there is a general state space representing aggregate uncertainty. When the economy is stationary and the underlying process governing aggregate uncertainty Markov, we provide Markov representations of the equilibria.Table of notation Agents' characteristics space ( ) - A Action space of each agent (aA) - Y Y = x A - Aggregate distribution on agents' characteristics - (X) Space of probability measures onX - C(X) Space of continuous functions onX - X Family of Borel sets ofX - State space of aggregate uncertainty ( ) - x t=1 aggregate uncertainty for the infinite game - = (1,2,...,t,...) - t t (1, 2,..., t) - L1(t,C ×A),v t Normed space of measurable functions from t toC( x A) - 8o(t,( x A)) Space of measurable functions from tto( x A) - Xt Xt= x s=1 t X - X t Borel field onX t - v Distribution on - vt Marginal distribution of v on t - v(t)((¦t)) Conditional distribution on given t - vt(s)(vts)) Conditional distribution on t given s (wheres) - t Periodt distributional strategy - Distributional strategy for all periods =(1,2,...,t,...) - t Transition process for agents' types - ( t,t,y)(P t+1(, t , t ,y)) Transition function associated with t - u t Utility function - V t (, a, , t) Value function for each collection (, a, , t ) - W t (, , t ) Value function given optimal action a - C() Consistency correspondence.

The purpose of this paper is to analyze strategic behavior of vertically integrated firms when there is downstream entry, taking into account the balance between competition in the market and competition for the market. This analysis can serve to explain diverse distributional structures, including the coexistence of vertically integrated firms and independent retailers. And it shows that the relative efficiency of downstream entrants and the level of competition among incumbents are two major factors in determining equilibrium configuration.  相似文献

In general, synergies across license valuations complicate the auction design process. Theory suggests that a simple (i.e., non-combinatorial) auction will have difficulty in assigning licenses efficiently in such an environment. This difficulty increases with increases in fitting complexity. In some environments, bidding may become mutually destructive. Experiments indicate that a properly designed combinatorial auction is superior to a simple auction in terms of economic efficiency and revenue generation in bidding environments with a low amount of fitting complexity. Concerns that a combinatorial auction will cause a threshold problem are not borne out when bidders for small packages can communicate.  相似文献

In the latest volume of Bruce Ackerman's We the People, he sets out to demonstrate that the Constitution has been legitimately amended by unconventional means, or by mechanisms other than the Article V amendment process. In making this argument, Ackerman offers a rich constitutional history of the Founding period, the Reconstruction era, and the New Deal. He successfully demonstrates that unconventional methods were used to alter accepted constitutional meaning and government practices during these periods. Unfortunately, Ackerman does not provide an adequate theory that can demonstrate the legal significance of these historical events for future constitutional practice. Moreover, his effort to legitimate the New Deal's constitutional revolution undermines his own normative theory of dualist democracy and seems to embrace a standard Legal Realist analysis that the Constitution simply is whatever powerful government officials declare it to mean.  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

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

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.  相似文献

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

Sherman (1992, 197) concludes that the wasteful use of capital [by a rate-of-return constrained monopolist] is motivated to avoid an inelastic region of demand. Previous analyses of capital waste by regulated firms often employ models with concavity restrictions on the profit and production functions. Here we demonstrate that these conventional assumptions in Averch-Johnson type models require demand to be everywhere elastic, ruling out the avoidance motive emphasized by Sherman. Although these highly restrictive assumptions are suitable for studying inefficient input mix, they are inappropriate when considering investment in unproductive capital.This note is based on the appendix to my doctoral dissertation completed at The University of Tennessee, Knoxville, and supervised by John W. Mayo. Useful comments were also made by Ross Eriksson of The University of Tennessee, David Kaserman of Auburn University, David Mandy of the University of Missouri, and an anonymous referee.

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).

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.  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.

Power,luck and the right index   总被引:1,自引:0,他引:1  
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.  相似文献

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.

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.  相似文献

Geographical Proximity and the Transmission of Tacit Knowledge   总被引:10,自引:1,他引:10  
Since at least the publication of Pigou's The Economics of Welfare (Pigou 1932) and Arrow's seminal article on Economic Welfare and the Allocation of Resources of Invention (Arrow 1962), most economic theorists have argued that knowledge is expensive to produce but cheap to reproduce. Following Hayek (1948) and Polanyi (1958), scholars working in the tradition of Austrian economists have dissented from that view by pointing out that if a good deal of knowledge, such as the price of gold, can be easily codified and transmitted, much important knowledge is tacit and dependent on the particular circumstances of time and place. One line of work that supports the Austrian view can be found in economic geography and neighboring disciplines where the geographic concentration of economic activity is explained, among other factors, by the importance of geographical proximity between individuals in the transmission of tacit knowledge. This paper therefore argues that the spatial agglomeration of economic activities constitutes a powerful vindication of Austrian insights.  相似文献

In a seminal contribution to the literature on bureaucracy, Breton and Wintrobe (The Logic of Bureaucratic Conduct: An Economic Analysis of Competition, Exchange, and Efficiency in Private and Public Organization. New York, NY: Cambridge University Press, 1982) develop a model wherein subordinates and superiors in a bureaucratic structure trade with each other to advance the objectives of the superiors. The success of such an organizational arrangement (for superiors) is based upon the development of vertical trust networks in a way that facilitates the promise of informal payments by superiors in return for informal services provided by their subordinates. Breton and Wintrobe [Journal of Political Economy 94 (1986) 905] also provide a theoretical application of their model by describing the Nazi bureaucracy as a conglomeration of competing agencies that zealously carried out the Final Solution to the Jewish question. As an extension, this note develops two compelling empirical examples of vertical and horizontal trust networks within the Nazi regime: Einsatzgruppen As (Special Action Detachments) attempt to liquidate all Lithuanian Jews after the German invasion of the U.S.S.R. in 1941 and the 20 July 1944 attempt to assassinate Adolf Hitler.JEL Classification: D23, D73.  相似文献
