Finance,investment and innovation: A theoretical and empirical comparative analysis

The paper compares the relative efficiency of country models in the relationship between finance and investments. Results, confirmed under three different panel data estimates (Arellano-Bond GMM method, random and fixed effect estimates) suggest that: i) the UK thick market reduces informational asymmetries for large firms and for those firms providing good signals to shareholders; ii) the Japanese vertical (between firms and banks) integration and horizontal (among firms) integration almost eliminates financial constraints (the horizontal integration effect) and equates agency costs across firms (the vertical integration effect). These results are consistent with the short-termist hypothesis which assumes that the Japanese economic system can process information more efficiently reducing managerial myopic behaviour and thereby determining positive effects on long term growth.     

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.     

Ein Entscheidungsmodell für Konsumieren und Sparen

Summary The present study analyses the simultaneous problem of consumption and saving by means of a consistent demand system; for this purpose the linear—expenditure—system (LES), developed by R. Stone, has been modified and used as a methodological base. Saving takes, for the sake of operationality, the character of a consumer—good and becomes an argument of the utility function. The usual neoclassical assumption of utility maximization allows the derivation of a linear expenditure system of consumption and saving (LESSC) when prices and income are given. The simultaneous LESSC-model has remarkable weaknesses, however: the assumption of certainty, the static character of the model, the disregard for major savings—motives and private expenditure on homebuiding led to bad elasticity—estimates. The assumpion of directly—additive utility functions causes furthermore collinearity between income—and price—elasticities such that the meaning of the derived elasticities is greatly reduced.The income—elasticities derived from the LESSC are positive throughout but show a remarkable variance. The calculation of the Friedman—bias demonstrates a rather strong bias due to the assumption of certainty. A modification resulted in income—elasticities of private consumption and savings of around 0,93 (unmodified: 0,88) and 1,41 (unmodified: 1,76). The demand for consumption goods of great necessity was income—inelastic whereas the demand for goods of less importance to survival was income—elastic. An analysis of income—elasticities of the disaggregated system and the relation between transitory components of consumption and income existing in Austria gave the impression that unexpected changes in income are not only reflected in saving but also in changes of the consumption—structure.The respective price—elasticites are all negative and smaller than 1. For less important consumption—goods lower price—elasticities have been measured and for easily substitutable goods higher ones. Marked crossprice—elasticities could only by discovered with clothing and food products. Generally it can be said that an increase in prices of goods of the daily needs hits both the expenditure on easily substitutable consumption goods and causes dissaving.A comparison with the elasticities calculated through OLS shows a greater reliance of LESSC—elasticities as far as data of differing aggregation levels are concerned.

Is Technological Progress Pareto-Improving for a World with Global Public Goods?

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.     

Constitutions for Local Collective Action and Institutional Interdependence

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.     

Strategy-proof and individually rational social choice functions for public good economies

Summary We consider the problem of choosing an allocation in an economy in which there are one private good and one public good. Our purpose is to identify the class of procedures of choosing an allocation which satisfy strategy-proofness, individual rationality, no exploitation and non-bossiness. Any such procedure is a scheme of semi-convex cost sharing determined by the minimum demand principle.I wish to thank Professors Salvador Barbera, Matthew Jackson, Herve Moulin and William Thomson for their helpful suggestions and two anonymous referees for their detailed comments. Conversations with Professors Hideo Konishi, Shinji Oseto Ken-ichi Shimomura and Stephen Ching were helpful.

Austrian economic policy

Zusammenfassung Die österreichische Wirtschaftspolitik wird in Österreich vielfach als austro-keynesianisch etikettiert. Der vorliegende aufsatz versucht zu zeigen, daß das Keynesianische dieser Politik nicht in einer Stop-and-go-Politik besteht, was üblicherweise als Keynesianismus bezeichnet wird. Vielmehr zielt die österreichische Wirtschaftspolitk darauf ab, intrinsische Instabilitäten des Marktprozesses als Folge von Unsicherheiten oder wechselnden Erwartungen durch gesamtwirtschaftliche Arrangements zu reduzieren: Sozialpartnerschaft, stabiler Finanzsektor, Unabhängigkeit der Investitionsentscheidungen von monetären Faktoren sowie Dominanz automatischer Stabilisatoren. Diese Reduktion von Marktinstabilitäten kann als fundamentale Politikempfehlung Keynes' angesehen werden.Der Terminus Austro in der Bezeichnung der österreichischen Wirtschaftspolitik weist darauf hin, daß es ein hausgemachtes Konzept ist, welches neben keynesianischen Elementen auch klassische Relikte, neoklassische Erweiterungen, monetaristische Vermutungen oder einfach Wirtschaftspolitik à la Hausverstand beinhaltet. Dies gilt insbesondere für eine Vielzahl von selektiven Eingriffen wie Investitions-, Spar- oder Exportförderung. Gemeinsam ist diesen selektiven Eingriffen, daß sie üblicherweise als Erklärungen für die Erfolge der österreichischen Wirtschaftspolitik herangezogen werden; der konkrete Beweis hiefür steht jedoch aus.Der Aufsatz unternimmt den Versuch, das austro-keynesianische Konzept theoretisch wie auch empirisch kritisch zu prüfen.

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.     

Transformation or Transmogrification? Ackerman, Hobbes (as in Calvin and Hobbes), and the Puzzle of Changing Constitutional Identity

In this article, I argue that Ackerman's approach to constitutional change is unable to distinguish between changes of degree and changes in kind, or between changes that transform and changes that transmogrify. As a consequence, the model Ackerman proposes fails at its most elemental purpose of illuminating questions of constitutional identity. Transformations fails to tell us who We the People really are or about what we are constituted.     

Technological change and institutional inertia: a game-theoretic approach

In this paper, we study a co-evolutionary model of economic change at two hierarchical levels. At the lower level, institutions are given and the focus is on how resources are allocated and innovation produced in response to the pay-off structure induced by prevailing institutions. At the higher level, it is the institutions themselves that change as the outcome of a process of social bargaining. The main objective of the paper is to study the interaction between these two levels of change, attempting to provide some insight on issues like technological/institutional divergence, technological dead-end, institutional inertia, etc.It appears that evolutionary economics must be the theory of a process of cultural growth as determined by the economic interest, a theory of a cumulative sequence of economic institutions stated in the terms of the process itself.

Robust Institutions

I propose to show how to translate the economic analysis of institutions developed in the tradition of worst case political economy into the lingua franca of robust statistics. An institution will be defined as contingent upon a design theory and the difficulty we consider is the use of the institution by the designer.The technical bridge between institutional robustness and statistical robustness is the the possibility of exploratory data analysis [EDA] with respect to the design theory. In an institutional context with EDA comes the recognition that the model is not completely specified, that we do not fully understand the structure of world before studying it. In a statistical context with EDA comes a non-normal error distribution.The relationship between evolutionary institutions and robust institutions is discussed. A conjecture that rule utilitarianism can be thought of as robust utilitarianism is defended with the historical example of William Paley's discussion of the utility of murder.     

Exchange rates and perfect competition

The purpose of this note is to demonstrate that the commonly held belief that incomplete and perverse pass-through are incompatible with perfect competition is wrong! To this end, we consider two types of firms both operating in two countries. The demand sides of the markets of the two countries are separated and each type of firm produces its good in one of these countries. We study the effect of an exchange-rate change on the competitive equilibrium prices in each country. When producing for the foreign market causes the same costs as producing for the home market then the law of one price holds and an exchange-rate change is completely offset by price changes. Furthermore, when cost functions neither exhibit economies nor diseconomies of scope between producing for the home and producing for the foreign market then prices move in the right directions in response to an exchange-rate change. However, with general cost structures, even in this simple perfectly competitive model, perverse directions of price changes can result from an exchange-rate change.     

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.     

Incentive compatibility and the quantity-setting competitive firm under demand uncertainty

This paper examines the tie between the popular black box neoclassical quantity-setting firm under demand uncertainty and a firm with a rudimentary but explicit employee relation organizational structure in which workers are offered fixed wages for following management directives. Surprisingly, the quantity-setting firm unambiguously mimics optimal employment relation hiring and work rules when the contract is incentive-compatible ex post. The attitude toward risk is shown to be the key determinant of whether or not the quantity-setting firm replicates the optimal employment relation contract when ex post incentive-compatibility is relaxed.     

Coordination as a Criterion for Economic “Goodness”

Welfare economics requires a criterion for economic goodness in regard to a society. Unlike conventional criteria, coordination (among independent decisionmakers) does not violate methodological individualism. The coordination criterion can be objectively deployed to judge events or policies, referring only to the given preference rankings of relevant individuals, given their initial positions. An important variant refers not to the attained (or unattained) state of achieved coordination, but to the ability of events or policies to affect the process through which a better-coordinated state may be approached. Several implications of the coordination criterion are explored.     

Technological paradigms,patterns of learning and development: An introductory roadmap

This paper presents an evolutionary microeconomic theory of innovation and production and discusses its implications for development theory. Using the notions of technological paradigm and trajectory, it develops an alternative view of firm behavior and learning. It is shown then how these are embedded in broader national systems of innovation which account for persistent differences in technological cappacities between countries. Finally, this bottom-up evolutionary analysis is linked with an institutional top-down approach, and the potential fruitfulness of this dialogue is demonstrated.We thank the discussants and participants at the workshop on Technology and Competitiveness in Developing Countries, Venice, 26/11/93, for their useful comments.The research leading to this work has benefited at various stages from the support of the Italian National Research Council (CNR, Progetto Strategico Combiamento Technologico e Crescita Economica) and of the International Institute of Applied System Analysis (IIASA, Austria).     

Die Komponenten des Rückganges der Ausländerbeschäftigung

Summary During the crisis of 1974/75 the number of foreign workers in Western European countries has been reduced. This has caused a new discussion about the benefits and drawbacks of the employment of foreign workers. Whatever the attitude towards this problem may be, it is useful to decompose the reduction of foreign labour into categories. First of all a certain amount of foreign labour will be reduced due to a general decrease of overall employment. This influence may be called proportionality effect. The share of foreign workers in the different branches of the economy allows the calculation of a structural effect. Both of them measure influences, which concern foreigners as well as nationals. Only the remaining influence is specific to foreigners. It may again be split into a reduction effect and a substitution effect. The former ist concerned with that part of total reduction of foreign workers, which corresponds to the decrease of employment, i.e. employment reduction by dismissal of foreign workers. The latter pertains to that part of reduction, which exceeds the decrease of employment, i.e. by this magnitude domestic labour has been substituted for foreign labour.The application of this model to the years 1974 and 1975 shows no proportionality effect (1974 it is even positive), a limited structural effect, but a high reduction effect. The substitution effect is considerable in 1974 but of minor importance in 1975. So foreign labour in Austria served actually as cyclical buffer but mainly by reduction and only partly by substitution.     

Communication in dynastic repeated games: ‘Whitewashes’ and ‘coverups’

Summary. We ask whether communication can directly substitute for memory in dynastic repeated games in which short lived individuals care about the utility of their offspring who replace them in an infinitely repeated game. Each individual is unable to observe what happens before his entry in the game. Past information is therefore conveyed from one cohort to the next by means of communication.When communication is costless and messages are sent simultaneously, communication mechanisms or protocols exist that sustain the same set of equilibrium payoffs as in the standard repeated game. When communication is costless but sequential, the incentives to whitewash the unobservable past history of play become pervasive. These incentives to whitewash can only be countered if some player serves as a neutral historian who verifies the truthfulness of others reports while remaining indifferent in the process. By contrast, when communication is sequential and (lexicographically) costly, all protocols admit only equilibria that sustain stage Nash equilibrium payoffs.We also analyze a centralized communication protocol in which history leaves a footprint that can only hidden by the current cohort by a unanimous coverup. We show that in this case the set of payoffs that are sustainable in equilibrium coincides with the weakly renegotiation proof payoffs of the standard repeated game.Received: 30 September 2002, Revised: 5 August 2003, JEL Classification Numbers: C72, C73, D82.We wish to thank an Associate Editor and Dino Gerardi as well as seminar participants at Arizona State, Columbia, Duke, Georgetown, Indiana, Montreal, Princeton, Rochester, Vanderbilt, VPI, the 2001 NSF/NBER Decentralization Conference, the Summer 2001 North American Econometric Society Meetings, and the Midwest Theory Conference, 2000, for useful comments and suggestions.

Sparen und Einkommensverteilung

Summary The wage and salary bill in Austrian manufacturing industry is divided into a fixed and a variable part on the assumption that wages of skilled labour and salaries can be regarded as fixed, wages of unskilled and semi-skilled workers as variable cost. The excess of value added (factor incomes) over the variable wage cost (gross profit) is shown to be more stable in the trade cycle than the excess of value added over the total wage cost (net profit); this accords with the idea of a relatively stable mark-up on variable cost.As a proportion of value added, gross profit and even more net profit in the above sense decline gradually over the period 1956 to 1972. This would indicate a declining degree of monopoly or increasing degree of competition which presumably applies mainly to the export markets. The hypothesis is advanced that more active competition has taken place in foreign markets which enabled Austrian manufacturing to increase its share in those markets. The reduction in profit margins was made possible by tax allowances i.e. by the quick write-off a considerable part of new investment. This tax allowances amounts to an interest free government loan to the investor, which in fact will not be repaid of the depreciation funds are reinvested immediately after the equipment is fully written off. The proportion of the industry's capital which is in this sense financed by the government increases over time as investment expands; a profit rate has to be earned only on the remaining capital stock, so that without reduction of the return on private capital the profit margins may be reduced. (The tax allowances thus amount to a virtual reduction of the capital coefficient which proceeds gradually over a long time.)The paper finally shows the relation between the share of savings and the share of corporate incomes in the total private income during the cycle. The share of saving moves with the cycle and this is made possible by a shift to corporate income.     

The “Dorfman Steiner” rule

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).
