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.     

Interdisciplinary economics

Summary Starting from Robbins and Hennipman and with the help of Becker and Lindenberg a theoretical framework has been constructed within which the strong points of economics and sociology are combined,viz,. the formal but relatively bare-bones modelling of economics and the often so much richer, in terms of social content, analysis of sociology. This theoretical framework also appears to enable more balanced analyses of the effectiveness and efficiency of legislation and regulation than the kind of law and economics so much in fashion at the moment, which is often not devoid of economism and in whichhomo econornicus still all too often figures as the prototype of man.(Economic Institute/Centre for Interdisciplinary Research on Labour Market and Distribution Issues (CIAV)); Associate of The Netherlands Interdisciplinary Demographic Institute (NIDI) in The Hague and the Interuniversity Center for Social Science Theory and Methodology (ICS).

On the scope of hydraulic macroeconomics: Some reflections on Alan Coddington's Keynesian Economics

Summary The questions which Alan Coddington's posthumous bookKeynesian Economics brings to the fore as well as the thought-provoking (rather than fully acceptable) answers it provides make it worthy of being taken up for further analysis and discussion. This review article is intended to be one possible contribution in this respect. It focuses on the way Coddington's book deals with subjectivist approaches in economics and criticises it for going astray in this respect by adopting a mistaken view on the proper method of economics and giving a mistaken interpretation of both Keynesian economics and the economics of Keynes.I am indebted to L. H. Hoogduin, I. M. Kirzner, J. A. Kregel, S. K. Kuipers, J.A.H. Maks, J. Muysken and J. Pen for their valuable comments and discussion on an earlier version of this paper. Of course, they cannot be blamed for any remaining errors.A. Coddington,Keynesian Economics: The Search for First Principles, George Allen and Unwin, London, etc., 1983. Pp. 129. £ 9.95     

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.     

Shocks and the Viability of a Fixed Exchange Rate Commitment

The incentive to renege on a commitment to a fixed exchange rate is shown to be state contingent. A fixed exchange rate policy is not viable under unusual circumstances, and the incentive to violate the commitment is larger in the case of contractionary shocks than in the case of expansionary shocks. The possibility that the exchange rate regime is changed in unusual circumstances has significant effects also under normal circumstances, implying systematic devaluation expectations, excessive real wages and (ex post) real rates of interest, lower output and loss of reserves, which in turn reduces the incentive to initiate a fixed exchange rate policy. Moreover, policyshifts may be contagious among countries.     

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.     

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.     

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.     

Policies for economic growth

Summary The old growth theory of the 1950s led to certain conclusions about the sorts of economic policies that would promote economic growth, and also about their limitations. The new growth theory of the 1980s makes much stronger assumptions and leads to correspondingly stronger conclusions about the scope of growth-promoting policy. This article argues that: (1) empirical work so far has neither confirmed nor denied the strong assumptions underlying the new theory; (2) the theory is worth pursuing because of its intrinsic interest and the possibilities it opens up; (3) whatever the final verdict on the new theory, both theory and evidence support the belief that significant long-run gains, even if not permanent changes in the growth rate, can be achieved by increased investment in the broadest sense, including human capital, technological knowledge, and industrial plant and equipment.Fifth Tinbergen Lecture delivered on October 4, 1991, in Amersfoort for the Royal Netherlands Economic Association     

International dollar liquidity and the Eurodollar market

Summary Transactions of Eurodollar banks affect international dollar liquidity (and the US payments balance) exactly as would identical transactions of US banks. Eurodollar banks are, however, usually more likely to grant credits to foreigners than US banks, and thus to raise foreign gross (thought not net) dollar liquidity. In times of international dollar glut, an expansion of the Eurodollar market (e.g., through shifts of deposits from US to Eurodollar banks or through US banks repaying Eurodollar borrowings) thus tends to aggravate unwanted dollar flows to foreign central banks and the US reserve transactions (though not the net liquidity) payments deficit.This paper is a by-product of the author's contribution to the study Foreign Dollar Balances and the International Role of the Dollar, conducted jointly with Professor Raymond F. Mikesell and sponsored by the National Bureau of Economic Research. Neither Professor Mikesell nor the National Bureau (nor the Foreign Service Institute) bears, however, any responsibility for the views expressed in this paper.     

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.     

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.     

Substitution assumptions versus empirical evidence in manpower planning

Summary There exist basically two manpower planning methodologies. Firstly, the manpower requirements approach which stipulates that there are needs in the economy for given numbers of qualified persons in the labour force. Secondly, the rate of return approach which focuses on the costs and benefits of producing one extra qualified person at the margin.This paper contrasts the theoretical foundations of the two approaches with particular emphasis on the degree of substitution between different types of educated labour. The empirical evidence on elasticities of substitution is reviewed and it is concluded that the cost-benefit model fits better the real world.I am indebted to Dr. Christopher Dougherty for reading a draft of this paper and making many important corrections.     

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.     

Het Liquid Iteiskarakter Van Spaartegoeden

Summary Before 1964, the Netherlands Bank did not count savings balances at money-creating banks and savings banks as secondary liquid assets or secondary liquidity (that is, near-money). Secondary liquid assets comprise claims on the public authorities and money-creating institutions, so far as they are held by other than money-creating institutions, which can be converted in large amounts into money at relatively short term without much expense or great loss on the transaction, or which can be used at their par value to make payments in satisfaction of current tax assessments.However, towards the end of the 1950's it became apparent from the rising value of the velocity of circulation of savings balances at financial institutions that these assets were acquiring increased significance for current payments. In 1964, this phenomenon induced the Netherlands Bank to count a certain part of the savings balances — indicated as liquid savings balances — as secondary liquidity, whereas the remaining part (true savings balances) was not. The Bank did so for better being able to impute the responsibility for monetary disturbances to the various sectors of the economy.Savings balances acquiring increased significance for current payments is a result of increased competition among financial institutions for the savings of the households sector. This increased competition is due to the fact that the households feel the need of more services rendered by the financial institutions as their income rise. Nowadays those financial institutions whose balance sheets do not comprise an item Current Accounts permit households to use their savings balances for making current payments. On the other hand, there is a tendency towards creating new types of accounts that serve as current accounts for the households in particular. If this tendency is followed up, the liquid assets character of savings balances will grow weaker.Rede, uitgesproken bij de aanvaarding van het ambt van gewoon hoogleraar in de staathuishoudkunde aan de Nederlandse Economische Hogeschool te Rotterdam op 28 september 1967.     

Mode of payment in household expenditures

Summary We have studied the choice of mode of payment from a 1987 Dutch household survey. The institutional arrangements of a transaction are a major determinant for the mode of payment, and so is the amount involved. A 10% increase in the sum paid usually leads to a reduction of about 1.3% to 2.3% in the incidence of currency use.Based on De keuze van een betaalmiddel (The Choice of Mode of Payment), (SEO, Amsterdam, 1989), which reports research commissioned by the Postbank, Amsterdam.     

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.     

Over het sociaal-economische gemenebest

Summary The title of this essay reflects the responsibility that people share in today's society for the outcome of the economic process to be efficient and equitable for everybody.Overcoming both the pursuit of Economic Welfarism and the separation of Efficiency and Equity, in welfare economics one has to look to a general understanding of the maintenance and furtherance of welfare on the physical, subjective and ethical levels. For that purpose, a recognition of the pluriformity of the ingredients of welfare is necessary. External effects, ecological problems and the scale of private, mixed and public goods, fall into that pattern.Openbare les, gegeven bij de aanvaarding van het ambt van gewoon lector in de staathuishoudkunde aan de Vrije Universiteit to Amsterdam op 22 september 1972.     

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.     

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.
