Rational spirits and the post Keynesian macrotheory of microeconomics

Summary The argument that post Keynesian theory rejects rationality and maximization as a basis of agent behaviour and is thus non-rational and lacking micro-foundations is contrasted by reference to Keynes' use of his early work on probability in the General Theory. Instead of presuming rational choice over perfectly known events, post Keynesian theory builds on Keynes' explanation of agents' rational beliefs in uncertain propositions about their knowledge of the world. These rational spirits lead to the recognition of the macro constraints to individual action or a macrofoundations of microeconomics linked to the role of money and to the role of liquidity preference as both a measure of rational belief and a determinant of money prices which equate the rates of return on all existing and newly produced goods. In this equilibrium prices will generally diverge from costs of production, in contrast to perfect competition but in concordance with the post Keynesian microeconomic theories of mark-up pricing.Comments by L. Hoogduin are gratefully acknowledged. He is relieved from any responsibility for my impressionistic presentation of Keynes' views on probability.     

Game equilibrium modelling

Summary Non-cooperative game theory has in recent years become one of the main tools in the social sciences and economics. It deals with decision problems of more than one (rational) player. The actions of those players result in outcomes that are the best that may have happened to a player, given the actions of the other players. This is precisely the content of the 'Nash equilibrium' concept. It would be nice when each game had a unique Nash equilibrium. Unfortunately, both non-existence and multiple equilibria occur. An important role in game theory is played by the information available to the players. Among the economic applications are: the Theory of Industrial Organisation, Bargaining and the Economic Theory of Information.Comments by Eric van Damme and Casper de Vries on an earlier draft of this paper have greatly improved the presentation. I have benefited from the comments of the editor and an anonymous referee ofDe Economist. For all omissions, all possible errors and the revealed views in this paper, I alone am responsible.     

Public pensions and political decision-making

Summary A simple decision-making model regarding the financing method and benefit level of a public old age pension is developed. In line with existing literature, the decision-making process is supposed to be in the form of direct democracy, initially, In order to apply the model to a situation of a representative democracy, to wit the Netherlands, five social groups are considered which may be assumed to influence the decisions taken by the government organization. The empirical results show unanimous support for the PAYG system actually chosen at the start of the pension scheme in 1956. The results are highly suggestive, furthermore, as regards the fact that the financing method of the pension scheme has recently become a parliamentary issue. If one endorses the view that long-term considerations should be given a more preeminent place in this context, which would demand a change of the decision-making structure in favour of the young, then the political support for such a change would seem to be present at the moment.The research reported in this paper is part of the project Economic Policy and Conflicts of Interests of the University of Amsterdam (PEPCI paper 85.03).

Hennipman and by participants in the workshop on The Origin and Future of Social Security Schemes at the Wissenschaftszentrum Berlin, December 13–14, 1984, in particular by Professor Charles Blankart, are gratefully acknowledged.     

Post- war European economic development as an out of equilibrium growth path. The case of the Netherlands

The paper examines a number of aspects of post-war economic development of the Netherlands in the light of recent out of equilibrium growth theory. It contains a comparison of the stylized facts of the long run performance of the economies of the United States and the Netherlands which suggests that the US has been on an equilibrium growth path for more than a century, but that the Netherlands followed a radically different growth path, especially after 1945. It is attempted to explain this erratic behaviour of the investment ratio and the wage share after 1945 by examining two aspects more in detail: the financing of the acceleration of growth after 1945 and the phase of too rapid growth during the 1950s and 1960s, when the growth of the demand for labour tended to be higher than the increase in its supply.     

Utility and economics

Summary Although utility has been the central concept in economics, economists have paid relatively little attention to its measurement. Generally, utility is measured indirectly via the revealed preference approach. We discuss problems with this approach and next introduce alternative direct measurement methods. The direct measurement methods are seen to spawn a so-called theory of preference formation, which explains differences in utility functions of different individuals. The similarities of this theory with related theories in sociology and psychology, and various sorts of empirical evidence, are reviewed. The paper concludes with a discussion of the implications of these findings for economic theories.This is a slightly adapted version of my inaugural address at Tilburg University. I thank Tom Wansbeek for his helpful comments.     

Financial instability and the real economy

Summary The paper deals with three different areas of the financial sphere: national moneys, exchange rates and financial claims, markets and institutions. For each of them, it tries to identify the main forms of instability which may occur, their causes and consequences for the real economy. Depending on the area concerned, the forms of instability include inflation, fluctuations and misalignments in interest rates, exchange rates and asset prices and finally solvency and liquidity crises of institutions. It is concluded that, over the last fifteen years, significant progress has been made in the policy framework to counteract instabilities in the national and monetary spheres. The conclusion is more mixed with regard to the structure of financial markets.[/p]We are grateful to Julian Alworth, Svein Andresen, Gavin Bingham, Joe Bisignano, Michael Hutchison and Paul van den Bergh for useful comments.     

The golden rule of accumulation and the open economy

Summary This paper examines the factors which determine the volume of consumption per capita in a small open economy in the long run. The analysis is based on a neoclassical model. It is proved that-in general — Phelps' golden rule of accumulation does not hold for an open economy. This conclusion follows from the decline in the terms of trade, which is generated in an open economy by an increase in the share of investment. The influence of labour supply and world expenditure on the consumption per capita also depend heavily on the induced change in the terms of trade. The analytical results of the model are illustrated by means of a few numerical examples.This paper is written within the framework of the research program Possibilities and Limitations of National and International Economic Policy, code K.H.T.

Exchange rate theories

Summary A four-period classification is used to categorise recent exchange-rate theories or models. In the very short period, only capital flows are relevant. In the short period, both capital flows and payments on the current account play a role. In the long period, the capital account and the current account are individually in equilibrium. In the very long period, purchasing power parity holds. Cash-in-advance models are dealt with separately. Many models that purport to explain exchange rates do in fact not provide for the exchange of currencies. No model stands up satisfactorily to econometric testing. Speculative bubbles, the peso problem and news play havoc with tests of the uncovered interest parity theorem, the core of the monetary models. This aside, the fundamental assumption of rational expectations itself is suspect. There does not seem to be such a thing as a true model.I am indebted to Dr. W.J.B. Smits and Professor J.W. Gunning for helpful discussions on a number of issues pertinent to this article.     

Tax Level and Tax Internalization Effects on Union Wage Bargaining

High taxes and generous social benefits are often blamed for causing unemployment. The conventional view is that if taxes on labour are (too) high, jobs will be lost and that generous social benefits will exert an upward pressure on unions' wage claims. In the case where unions co-ordinate their wage bargaining strategy, this need not be the case. A simple model is used to illustrate the effects of the tax rate level and tax internalization on unions' wage bargaining strategy. A high marginal tax rate along with endogeneity of the average tax rate shifts the union's trade-off between wages and employment in favour of the latter. These shifts may have contributed to the success of the so-called polder model or tulip model of the Netherlands.     

ECB Foreign Exchange Intervention and the EURO: Institutional Framework,News, and Intervention

Using a unique intervention news data set, this paper investigates the impact of ECB intervention and intervention-related news (newswire reports) on the Euro exchange rate. A time-series study of news generated by ECB officials and market participants regarding intervention and the value of the Euro as well as an event study of firm reports of ECB intervention is conducted. Both studies find significant short-run effects on the Euro value, while only negative statements (official statements denying past intervention or ruling out future intervention) appear to have persistent effects.     

The Dutch Transportation System in the nineteenth Century

The actual discussion on the Betuwe-line and the construction of this new railway for freight transportation from Rotterdam to Germany is placed into a historical perspective. Right from the beginning of railway history in the Netherlands, the construction of an Iron Rhine was disputed. As analytical tool, the social saving approach is used. The conclusion of this cost-benefit analysis is that it did not and does not matter that much for the level of welfare in the Low Countries or the Rhineland whether the goods from major coastal ports are transported on the river Rhine or by the four Iron Rhines.     

Smoke of leets

Summary This is a review of some of Mrs. Joan Robinson's ideas, and the author's conclusion is that these ideas do not contribute to the present state of economic theory. Her view on international trade is lopsided, her criticism of traditional capital theory goes too far, her refutation of income distribution theory is mainly unfounded. Basically, Mrs. Robinson rejects the notion of relative scarcity of capital; the author believes that this is a useful notion in economics. Moreover, her recent work shows a strong anti-empiricist tendency. If Mrs. Robinson's negative train of thought were to be applied to all concepts of macro-economic theory (total labour force, real national income etc.) these concepts would vanish in thin air. The whole of macro-economics might go up in smoke.     

Strategic Interaction in the Dutch Market for Consumer Magazines

Information goods such as newspapers and magazines have a number of distinct economic characteristics such as a high fixed cost – low marginal (variable) cost structure and the possibility to subsidize content through selling advertising space. We develop a simple one-shot duopoly model that analyses strategic interaction in a market with such features. We focus on the firms best responses and test the theoretical predictions of the model empirically by panel regression techniques using a balanced panel data set of 60 Dutch consumer magazines over the period 1991–1998. Our 3SLS estimation results confirm the prediction of our model that the Dutch market for consumer magazines is characterized by strategic complementarity between magazine and ad prices.     

Forward exchange,short term capital flows and monetary policy

Summary This paper re-examines the relationships between short term capital flows and monetary policy, in the light of a new theoretical approach of the forward exchange market. They contend that the traditional forward exchange market theory is a misleading one as it fails to give all the importance it deserves to the distinction between covered and uncovered exchange transactions and to the actual role of the arbitrageurs. As a consequence of this analysis, they demonstrate that the problem of monetary management in an open economy must be dealt with in a way different from what has been usual, and they conclude that monetary policy, central banks' intervention on the foreign exchange market and direct controls on capital movements can still have some efficiency in the struggle against inflation, either of the domestic or the imported type.     

Bertrand Price Competition in a Social Environment

We analyze the dynamic behaviour of firms that locally interact through price competition in a social environment in an evolutionary game-theoretic model. These firms update their prices according to the behavioural rule Win Cooperate, Lose Defect (WCLD), which is often observed in experimental economics. It can be regarded as a generalized Tit-for-Tat strategy. The model can explain the simultaneous emergence of collusive behaviour, price dispersion and occasional local price wars. Price wars only last for a short period of time after which the firms start to collude again.     

Art and Appropriability in Renaissance Italy and The Netherlands in the Seventeenth Century: The Role of the Academy

The concepts selection systems and appropriability are used to discuss the developments of the competitive process between painters and the strategic choices open to them in Renaissance Italy and The Netherlands in the seventeenth century. The presence or absence of an academy, an institution such as the Florentine Accademia del Disegno, is seen to be a crucial factor with respect to safeguarding appropriability in the new selection system that replaced market selection.     

Testing Korteweg's rational expectations model for a small open economy

Summary Korteweg extended the Barro, Lucas, Sargent, Wallace type of rational expectations model to a small open economy. This paper tests Korteweg's model with Dutch data. A major error in the specification and estimation is pointed out and corrected: the differenced expected variables are not defined consistently. This error implies that Korteweg's and Bomhoff's previous empirical results on the model are invalid. The test results for the corrected model indicate that this model has to be rejected for The Netherlands. The restrictions implied by an extremely simple empirical alternative are, however, not rejected.I would like to thank Dr. Th.E. Nijman, Professors F. van der Ploeg, W.H. Buiter and J.J.M. Theeuwes and Dr. A. J. de Zeeuw for their stimulus and helpful comments on previous versions of this paper, and Professor P. Korteweg for his open-minded attitude towards this research.

Differentiation of Skills, Firms’ Recruitment Strategy and Unemployment Benefits in an Efficiency Wage Model

It is well known that the recruitment strategy of firms depends on the state of the labour market. In order to account for this fact, we build a matching model where the differentiation of skills is explicit. Along the line of Salop (1979b) workers and firms are distributed on the same circle and the distance between two points on this circle measures the mismatch between a firm and a worker. Another feature of this model concerns wage setting. In a natural way, wages are subject to the constraint that good workers (i.e. workers who are not too far on the circle) prefer to keep their job. In addition, on a suggestion by Phelps (1992), we assume that workers who quit their job are not eligible to unemployment insurance. Two main results are established. First, the lower the tightness of the labour market the more stringent the requirements of firms are. Second, as a consequence of the incentive constraint, unemployment benefits appear to raise employment.     

The infant industry argument for protection: A reevaluation

Summary Despite its importance as an exception to the free trade case, the argument for infant industry protection has only sporadically been subjected to close theoretical scrutiny. This article helps to fill this gap by evaluating the various traditional and modern perceptions of the topic. The paper concludes that none of the existing formulations of the infant industry theory are fully satisfactory. The classical view on the argument seems too static and too restrictive, whereas the modern approaches fail to provide a convincing theoretical framework. The proposed reappraisal of the infant industry idea is based on the classical principle of comparative advantage, but places the argument in the dynamic context of modern theories.     

Economic theories of leisure: Some comments and suggestions

Summary Most economic theories of leisure are concerned with valuations of leisure time related to income as an opportunity cost. After a critical discussion of these theories, leisure time as a constraint is introduced in the theory of consumer behaviour by (1) distinguishing between pleasant and unpleasant consumer activities, (2) discussing the effects on individual's welfare of changes, in the duration of both types of activities and (3) developing time-saving concepts. A theoretical framework for consumer choices under time and/or income constraints leads to suggestions for the lines along which leisure research should be developed as a basis for welfare policy in the widest sense.My thanks are due to Professors P. Hennipman, L. H. Klaassen, A. Pais and Mr. D. B. Needham for the valuable suggestions they made during the preparation of this article. Several parts of it will be presented in a more detailed form in a thesis on the subject.
