Endogenous Money: A Note on Some Post-Keynesian Controversies

Keynes's theory of liquidity preference sought to illuminate the essential properties of money under the conditions of uncertainty that often lead to involuntary unemployment. Subsequent Post-Keynesian literature built upon this concept to show that a deregulated financial system could induce phases of endemic financial instability and crises. Keynes's finance motive provides an important starting point in Post-Keynesian theories of endogenous money. This article examines the controversies between two major contending analytical approaches, the Horizontalist and Structuralist schools.     

Is ex‐ante ex‐post analysis irrelevant to Keynes's theory of employment?

Ex‐ante ex‐post analysis has become a standard tool in macroeconomics. Yet Keynes dismissed it. We argue that Keynes's dismissal of ex‐ante ex‐post analysis is not an oddity but an indication of the originality of his theory of employment compared to standard macroeconomics. First, the principle of effective demand does not amount to a process that determines employment and income at the point of intersection of the traditionally defined ex ante supply and demand functions. Second, the finance motive allowed Keynes to confirm the identity of aggregate supply and demand already asserted in The General Theory. This latter conclusion is puzzling, however, since the principle of effective demand presupposes the possibility of a discrepancy between supply and demand. We suggest that Keynes's theory of employment is linked to a theory of income distribution whereby profits are a redistributed share of factor income which is transferred to firms when prices exceed factor costs. The identity and the equilibrium condition then relate to separate measurements of income and output, factor cost and prices.     

Of clouds and clocks and Keynes: conceptions of reality and the growth of knowledge function of money ∗

In this paper, John Maynard Keynes' General theoryand the concept of money are given an evolutionary interpretation. This interpretation is based on Karl Popper's delightful essay ‘Of clouds and clocks: an approach to the problem of rationality and the freedom of man’. The essay presents two things: Popper's conception of indeterminism and his general theory of abstractions. Popper's general theory concerns the role of abstractions and rule-governed, hierarchical systems of abstractions in structuring an indeterministic and uncertain world. He applies his general theory to science.Popper maintains that science is an abstract, rule-governed, linguistic process that facilitates criticism as a way of learning about our world. Popper calls this the growth of knowledge function of science. Popper's general theory can be applied to Keynes' General theory. Following Popper, I argue for a conception of the economy as a rule-governed, monetary language of commerce that facilitates critically minded inquiry in the domain of ordinary economic transactions. A monetary system facilitates the growth of commonsense knowledge in the economy. I call this the growth of knowledge function of money. An awareness of indeterminism and a growth of knowledge like function of money seem to pervade Keynes' General theory.     

The Role of credit in a Keynesian monetary economy

Abstract

This paper describes the features of a monetary economy on the basis of Keynes's distinction between a real exchange economy and a monetary economy. In The General Theory, Keynes identifies the reasons for the non-neutrality of money by highlighting the store of wealth function of money; this approach has been adopted by most Keynesian economists. The aim of this paper is to show that such an approach only partially explains the reasons for money non-neutrality and that important elements which demonstrate the relevance of monetary variables emerge when the means of payment function of money is considered. Investigating the role of this function requires that we deal explicitly with how spending decisions are financed. The paper argues that the market for credit must be considered separately from the market for money, and that a viable credit theory can be built from Keynes's post-General Theory writings.     

The Significance of the Monetary Context of Economic Behavior

The dominant paradigm in economics views economic behavior as allocative activity in a neutral, C-M-C' economy. As a consequence, money is treated as a veil that is inessential to the real functioning of the economic system. This paper argues that one of Keynes's fundamental insights is the significance of the monetary context of economic behavior. This insight has been developed by the post-Keynesian theory of money as a "time-machine vehicle" that provides the causal link between uncertainty and unemployment. The Circuitist theory of money as the means of final payment provides a complementary radical perspective on the significance of the monetary context. This paper investigates the methodological and theoretical implications of these radical monetary theories and assesses their contribution towards the development of a general theory of a monetary production, M-C-M' economy.     

An Alternative Monetary Model of Inflation and Growth

This paper presents a simple model of a monetary economy in which production takes time and is financed by loans from financial intermediaries such as banks. The model is an example of a pure credit economy, but does not contain the contentious Wicksellian construct of a natural rate of interest. Rather, the main determining factor of economic outcomes is the struggle over income distribution between finance (Keynes's rentiers), industry, and labour. The model yields a number of macroeconomic results, some of which are sharply at variance with those obtained in more orthodox or mainstream, models. In particular, a structural long-term Phillips-curve type relationship emerges in inflation-growth space, for some demand-side and monetary policy changes. In addition, the model is also able to identify other circumstances in which the opposite cases of either stagflation or non-inflationary growth can occur.     

Keynes and India, 1909–1913: a study on foreign investment policy

Abstract

Keynes's work on India before the First World War concentrated on analysis of the gold exchange standard and the stabilization of the rupee external value. Indian monetary arrangements were framed into a plan for foreign investment, implemented by the India Office in London. This policy, which was a typical example of public control over investments, occasioned Keynes's first job as an applied economist. Although neglected by Keynesian scholarship, this learning by doing experience is likely to have played a significant role in the young economist's training and education.     

On Keynes' inverse relation between real wages and employment: a debate over excess capacity ∗

This article examines Keynes's argument in favour of an inverse relation between employment and the real wage rate. In examining the debate over the inverse relation that took place during the 1930s the article argues that the failure of Keynes's critics to persuade him to relinquish the inverse relation can be traced to his own unrecognized use of a concept of marginal productivity different from theirs but that the larger unresolved issues persisting throughout that debate and continuing till the present are those relating to the formulation of ‘excess capacity’ during a depression and the specification of the supply side of the underemployed economy. Drawing on that debate but contrary to Keynes's own response, the article will propose a respecification of excess capacity such that the labour market directly incorporates aggregate demand independently of changes in the price level, and where an increase in employment is not predicated on a reduction in real wages even in the presence of (neoclassical synthesis) diminishing returns.     

KEYNES ON WAGE FLEXIBILITY AND THE AUSTRALIAN WAGES SYSTEM*

Keynes' General Theory briefly discusses the Australian wages system, as an example of a system in which an attempt was made to fix real wages by law. Keynes argues that such a system, strictly enforced, generates an unstable unemployment equilibrium or highly volatile money wages and prices. This paper clarifies Keynes' views on the Australian system, with a view to their wider relevance for the significance of real and money wage flexibility and inflexibility in Keynes' economics. The most striking finding is that money wage stickiness is a conclusion, not an assumption, of Keynes' theory of employment.     

The Point of Effective Demand

Abstract

Keynes's principle of effective demand conceives competitive equilibrium in terms of the choices of entrepreneurs, investors and consumers, rather than of the optimal allocation of factors of production. In The General Theory, effective demand is distinguished from aggregate demand and from income, expected or realised, and there is no suggestion that equilibrium means the convergence of expectations. Reconsideration of Keynes's use of time and equilibrium periods leads to the conclusion that he treats employment as in continuous equilibrium, at the point of effective demand, determined by the state of expectation, the correctness of which is strictly irrelevant. The nature of the equilibrium represented by the point of effective demand is here described, not in terms of the multiplier, but in terms of the continuous equilibrium of supply and demand in short-term forward markets. This reading is faithful to Keynes's conception of aggregate demand as dependent upon the expectations of entrepreneurs, and it resolves the meaning of his ‘long-period employment.’ Formal appendices identify the differences between Keynes and Walras and the nature of the multiplier. The paper concludes that the Keynesian cross and ‘Swedish’ analysis should be abandoned, and the Walrasian conception recognised as only the limiting case of general competitive equilibrium in a monetary economy.     

Sraffa,Keynes and 'The Years of High Theory'

This paper argues that Shackle's interpretation of 'the years of high theory' is flawed. Shackle (1967) sees Sraffa's critique of the Marshallian theory of value only as a step in the development of the theory of imperfect competition. In the same vein, Shackle reduces the message of Keynes's General Theory to the claim that unemployment results from the existence of uncertainty and irrational expectations. Thus, Shackle leaves open the possibility that both Sraffa's critique of Marshall and Keynes's theory of effective demand do not question the internal coherence of neoclassical theory, but instead merely assert that market imperfections render it irrelevant for the analysis of the real world. This paper argues, in contrast, that the theories of Sraffa and Keynes should be interpreted as radical departures from marginalism, and represent a return to the surplus approach of classical political economy.     

Keynes and probability: An assessment

Abstract

Most interpreters agree that Keynes had a wide-ranging, complex, ‘vision of the world’, which underlies his theoretical contributions. Whenever this is forgotten, as happens in the so-called neoclassical synthesis, not only the original Keynesian spirit goes lost but also, and especially, we lose substantive bricks for our theoretical constructions. The paper considers an important instance of this general rule; namely Keynes's views on the logic of probability, meant as the field concerning human behaviour in an uncertain world (hence connected to, but distinct from, the pure theory of probability, meant as a field of mathematics). The paper begins by recalling the main aspects of the classical and frequentist approaches to probability and the main criticisms they received, pertaining among other things to the limits of their applicability. We then consider Keynes's own views, stressing three aspects: the definition of probability as pertaining to the field of logic, the notion of uncertainty and of the ‘weight of the argument’, the ‘theory of groups’. We then discuss the subjective approach of de Finetti, Ramsey and Savage, and contrast it with Keynes's own views. Finally, we consider the implications of our analysis for the interpretation of Keynes's General Theory, and of his attitude towards econometrics.     

Keynes's realisms

Abstract

Some authors pointed to a realist orientation in Keynes's thought. However, since ‘realism’ is a wide and sometimes equivocal term, one may ask what kind of realism Keynes's realism is. This paper argues that Keynes held to an ontological, logical–semantic and epistemic realism. Whereas ontological realism has metaphysical connections, logical–semantic realism involves a notion of truth, and epistemological realism presupposes a theory of knowledge. The character of the subject matter circumscribes the scope of this last kind of realism. Epistemological realism is related to the role of intuition and convention in Keynes's thought, the meaning and evolution of which is explained.     

Money as an Institution of Capitalism: Some Notes on a Monetary Theory of Uncertainty

Dillard notes that to consider money as an institution of capitalism means to emphasize that money is an essential element in explaining fluctuations in income and employment. He states that Keynes's liquidity preference theory offers a sound explanation of money as an institution of capitalism. Keynes's explanation is based on a necessary condition, independent of money: the presence of uncertainty. The objective of the paper is to elaborate a different explanation of the role of money, based on Keynes's 1933 and 1937–39 works, according to which the presence of money constitutes the necessary condition to justify the importance of uncertainty.     

Keynes,Ricardo and the classical theory of interest

Keynes made harsh and repeated attacks on the work of Ricardo, blaming him particulary for what Keynes called the ‘classical theory’ of interest. Garegnani and others argue that Keynes' criticisms of the classical theory of interest apply to later neoclassical writers, but not to Ricardo. This paper re-examines Keynes' criticisms. It argues that Keynes attacked Ricardoapos;s theory of interest despite his awareness that Ricardo did not hold the ‘classical theory’. Moreover, Keynes not only expressed sympathy for Ricardo's understanding of interest, but his criticisms which do apply to Ricardo do not address Ricardo's theory of interest.     

Volume XXXIV – 2000

In the attempt to deepen the understanding of Keynes' thought as an international macroeconomist, we explore the hypothesis of consistency between his general methodological approach to the economic material and his way of reasoning about international economic relations. As a first step toward this direction, we investigate the methodology of The Economic Consequences of the Peace and find that it reflects Keynes' attempt to cope with the attributes of the complexity characterizing the European settlement for the post-war period, e.g., 1) organic interdependence among variables at play, 2) irreducible dilemmas and situations of conflict, as well as 3) the need for external, public assistance to overcome the impasse and promote a "shared responsibilities" approach to the imbalances. Striking similarities appearing with the method of Keynes' economic diplomacy in the 1940s are shown to substantiate the current rediscovery of his plans for Bretton Woods.     

Beauty contested: how much of Keynes' remains in behavioural economics' beauty contests?

Abstract

In one of the most famous passages of the economic literature, John Maynard Keynes likens the stock market to a beauty contest (BC), in which the winners are those who anticipate the average opinion. In behavioural economics there have recently been attempts at investigating the BC experimentally. We argue that there exist important differences between Keynes' and behavioural economics' BCs. We identify several types of BCs and propose a taxonomy. We also suggest that, in spite of these differences, Keynes' theory of decision under uncertainty is central to understanding the actual behaviour observed in experimental BCs.     

Economy as Instituted Process: Change,Transformation, and Progress

During the past two decades, chronic fiscal deficits have led to elevated and rising ratios of government debt to nominal GDP in Japan. Nevertheless, long-term Japanese government bonds' (JGBs) nominal yields initially declined, and have since stayed remarkably low and stable. This is contrary to the received wisdom which holds that higher government deficits and indebtedness will exert upward pressures on nominal yields. This paper examines the relationship between JGBs' nominal yields and short-term interest rates, as well as other factors, such as low inflation, persistent deflationary pressures, and tepid growth. We also argue that Japan has monetary sovereignty, which gives the Japanese government the ability to service its debt, and enables the Bank of Japan (BOJ) to keep JGBs' nominal yields low by ensuring that short-term interest rates are low, and by using various other tools of monetary policy. The argument that short-term interest rates and monetary policy are the primarily drivers of long-term interest rates follows John Maynard Keynes's (1930) insights.     

An overview of probability,expectations, uncertainty and rationality in Keynes's conceptual framework 1

Keynes's writings on the cognate topics of probability, expectations, uncertainty and rationality exhibit considerable complexity. This paper seeks to provide a clarifying overview of his position on these topics, both in his main philosophical workThe treatise on probability, and his main economic workThe general theory. It is argued that the most useful approach for understanding the deeper structure of Keynes's thought in each work is by means of a two-dimensional, two-domain analysis.Such an analysis helps demonstrate some of the ways in which the conceptual framework of The treatise on probability provides an essential part of the philosophical foundations of The general theory, while at the same time recognizing some of the key differences between the two works. It also illuminates Keynes's non-neoclassical theorization of rationality, and his path-breaking attempt to develop a theory of rationality under irreducible uncertainty.
