Endogenous Money, Circuits and Financialisation Malcolm Sawyer Endogenous money, circuits and financialisation Malcolm Sawyer January 2013 Abstract: The paper locates the endogenous money approach in a circuitist framework. It argues for the significance of the credit creation process for the evolution of the economy and the absence of any notion of ‘neutrality of money’. Clearing banks are distinguished from other financial institutions as the providers of initial finance in a circuit whereas other financial institutions operate in a final finance circuit. Financialisation is here viewed in terms of the growth of financial assets and liabilities, of non-bank financial institutions and changes in the predominant flow of funds between firms, households and rentiers. Some of the issues for the way in which the circuit analysis is developed are considered. Key words: endogenous money, monetary circuit, financial instability Journal of Economic Literature classification: E40, E44 Address: Economics Division, Leeds University Business School, University of Leeds, Leeds LS2 9JT, UK Email: [email protected] Endogenous money, credit rationing and financial instability Malcolm Sawyer1 1. Introduction It is generally recognized in post Keynesian circles that money is credit money created through the loan processes of the banking system (‘endogenous money’). This observation places banks centre stage with regard to the expansion of economic activity. The loan— credit money creation has also been generally, but not universally, associated with investment expenditure as resulting from the loans. As Kalecki observed ‘the possibility of stimulating the business upswing is based on the assumption that the banking system, especially the central bank, will be able to expand credits without such a considerable increase in the rate of interest. If the banking system reacted so inflexibly to every increase in the demand for credit, then no boom would be possible on account of a new invention, nor any automatic upswing in the business cycle’ (Kalecki, 1990, p.489). Decisions by banks on the provision of credit is not only a matter of the quantity (important as that is for the level of demand and thereby the level of economic activity) but also on the composition of credit recipients with regard to, for example, different types of business, different groups in society, ethnic and gender composition etc.. In a monetary production economy, the endogeneity of money recognises that money creation is an integral part of the ways in which that economy operates, rejecting any notion of the classical dichotomy of separation between the real side and the monetary side of the economy, with the structure and evolution of the economy impacted by the credit creation process. Thus unlike the ‘weak’ endogeneity introduced by new Keynesian economics in its ‘new consensus macroeconomics’ mould where the effects of monetary policy is limited to the rate of interest (in contrast with the fascination of monetarism with the quantity of money) with little consideration of how the loans (and thereby money) enters the economic system2. The 1 This paper reflects research being conducted within the project Financialisation, Economy, Society and Sustainable Development (FESSUD) (www.fessud.eu) which is a five year project funded by the European Commission Framework Programme 7 (contract number 266800). Discussions with Marco Passarella have informed the work here though without implicating him in the use to which I have put those discussions. I am grateful to Phillip Arestis for comments on earlier draft. 2 In the new Keynesian version, monetary policy can be represented by the interest rate (as set by the central bank) and the residual nature of the stock of money is recognized but a loanable funds approach to savings and investment is retained, and the processes by which money created is largely ignored. See, for example, Arestis and Sawyer (2005) for comparison between endogenous money as viewed by post Keynesians and by 1 stock of money is treated as something of a residual dependent on the ‘demand for money’ (and as we argue below there is not a ‘demand for money’ in any genunine sense in a world of endogenous money. Romer argues that ‘The key assumption of the new approach is that the central bank follows a real interest rate rule; that is, it acts to make the real interest rate behave in a certain way as a function of macroeconomic variables such as inflation and output. This assumption is a vastly better description of how central banks behave than the assumption that they follow a money supply rule’ (Romer, 2000, p.154)3. This may be so but it clearly puts the source of a horizontal supply of money curve as the behaviour of the Central Bank, and does not seriously consider the role of the banking system and their ability to create bank deposits Much of the focus of attention of the debates over endogenous money has been on the relationship between the loan rate of interest (viewed as a mark-up over the Central Bank policy interest rate) and the quantity of loans, and then by extension the quantity of money. This was reflected in the title of the first major book on endogenous money (Moore, 1988) – Horizontalist and Verticalist—with its advocacy of viewing the money supply as horizontal (in quantity of money, interest rate space) rather than the vertical money supply curve in the monetarist and related literatures. It developed in the debates between accommodationists and structuralists (e.g. Pollin, 1993, Lavoie (2006) and Dow (2006) for contrasting positions). Following Fontana (2004) those differences can be seen as relating to different modes of analysis with ‘[t]he disagreement between horizontalists and structuralists arises from the particular assumptions made about the general state of expectations of economic agents. Horizontalists rely upon a single-period framework that is built on the assumption that the state of expectations of all agents involved in the money supply process is given and constant’. Further, ‘structuralists depend on a continuation framework that explicitly takes account of the fact that the state of expectations of agents the ‘new consensus macroeconomics’, and the different policy approaches which flow. For the determination of the rate of interest, the NCM has in the short-term a rate set by the central bank (presumably in pursuit of inflation targeting), around a ‘natural rate of interest’ which comes from a sort of loanable funds approach located in a non-monetised economy. 3 This type of approach suffered from an inadequate treatment of how base money would be translated into broader money. Usually, there would be some appeal to the credit multiplier between base money and some broader definition of money, but the mechanism whereby banks would create loans in response to the demand for loans and the links thereby between expenditure and money creation were generally ignored. Indeed in the NCM in general there are no banks! 2 may change in the light of realized results. In this way, structuralists are able to tackle controversial issues related to shifting monetary policies, liquidity preference and the credit–deposits nexus that are ignored in the horizontalist approach’ (Fontana, 2004, p.382). We have in any case argued elsewhere (Sawyer, 2008) that the supply curve when the actual supply is undertaken to meet demand takes on a horizontalist appearance in the sense that the price at which a firm is willing to supply is set at the beginning of ‘the day’ and within that day supply is made to meet the demand which is forthcoming. The supply curve of, for example, a restaurant will have that horizontal appearance in that the prices are set at the beginning of the trading period and then any demand which is forthcoming at those prices is met (up to the capacity of the restaurant). One question is then the basis on which the price is adjusted in light of experience—if demand each day is persistently higher than expected when the price was set, at what point is the price changed; if the costs of production change at what point is the price changed. There are obvious implications for banks setting the loan interest rate, and the responses of that interest rate to changes in the central bank policy rate. In this paper, we do not explore the ways in which banks set the loan interest rate, and treat the question of whether the supply of loans can be regarded as horizontal or not as a secondary issue. It is also the case that we do not delve into how and why the central bank sets the interest rate, though this may have significant implications for the way in which the economy operates. Over the course of the trade cycle, the ways in which banks adjust the loan interest rate and the factors which influence the banks decisions, in conjunction with the decisions made by the central bank on the policy rate of interest will have consequences for the precise manner in which the business cycle develops. The focus of our discussion here is on the workings of the monetary circuit. The creation of money through the loan process is, of course, only the start of a process, and the circuitist approach4 provides clear expression of the loan creation and destruction processes. The endogeneity of credit money and the circuitist approach are general ideas which have to be applied to specific sets of circumstance. In this paper, we argue that features such as (i) the purposes for which loans are provided (investment purposes, consumption, or purchase of existing financial assets), (ii) the relationship between the 4 See, for example, Gnos (2006), Realfonzo (2006) and Graziani (2003). 3 financial sector more generally and the banking sector, (iii) the identity of savers and investors (that is those making fixed capital formation decisions).

Modern Monetary Theory: A Marxist Critique Abstract Compiled from a series of blog posts which can be found at "The Next Recession." Modern monetary theory (MMT) has become flavor of the time among many leftist economic views in recent years. MMT has some traction in the left as it appears to offer theoretical support for policies of fiscal spending funded yb central bank money and running up budget deficits and public debt without earf of crises – and thus backing policies of government spending on infrastructure projects, job creation and industry in direct contrast to neoliberal mainstream policies of austerity and minimal government intervention. Here I will offer my view on the worth of MMT and its policy implications for the labor movement. First, I’ll try and give broad outline to bring out the similarities and difference with Marx’s monetary theory.

Box 5000 Annandale-on-Hudson, NY 12504-5000 http://www.levyinstitute.org Copyright © Levy Economics Institute 2014 All rights reserved ISSN 1547-366X Abstract Since the beginning of the fall of monetarism in the mid-1980s, mainstream macroeconomics has incorporated many of the principles of post-Keynesian endogenous money theory. This paper argues that the most important critical component of post-Keynesian monetary theory today is its rejection of the “natural rate of interest.” By examining the hidden assumptions of the loanable funds doctrine as it was modified in light of the idea of a natural rate of interest— specifically, its implicit reliance on an “efficient markets hypothesis” view of capital markets— this paper seeks to show that the mainstream view of capital markets is completely at odds with the world of fundamental uncertainty addressed by post-Keynesian economists, a world in which Keynesian liquidity preference and animal spirits rule the roost.

  • The Endogenous Money Supply: Crises, Credit Cycles and Monetary Policy
    The endogenous money supply: crises, credit cycles and monetary policy Vadim Kufenko, University of Hohenheim [email protected] Abstract The given paper represents theoretical and empirical analysis of credit-cycles. Having considered theoretical foundations of credit-driven business cycles including financial instability hypothesis of Minsky, we formulate a predator-prey model of “bad” debt-driven credit cycles and include liquidity into the system, which allows us to account for monetary policy. After running simulations we show that counter-cyclical liquidity management performed by central banks allows banking systems to overcome debt deflation with smaller losses and raises the debt ceiling. HP filtered series of real loans clearly exhibit cycles and with the help of VAR models we were able to verify the validity of the predator-prey model and its liquidity extension for the US. Russian data showed that “bad” debt-driven credit cycles are to a certain extent relevant for countries with emerging financial and banking systems. Keywords: financial instability, debt deflation, predator-prey, vector autoregressions, Granger causality Introduction The goal of this paper is to revise the endogenous money supply and credit-driven business cycle theories in terms of new economic reality and stress their viability after accounting for credit cycles and monetary policy. The recent economic crisis has demonstrated the relevancy of financial instability and shown that credit disruptions pose a serious threat to corporate and, as it becomes more and more obvious, sovereign solvency. Needless to say, once being forced to implement such unprecedented measures as exogenous quantitative easing, one should at least consider the endogenous nature of money supply variations in order to understand the potential consequences.

  • Modern Monetary Theory and the Public Purpose
    Modern Monetary Theory and the Public Purpose Dirk H. Ehnts (Technical University Chemnitz) Maurice Höfgen (Samuel Pufendorf-Gesellschaft für politische Ökonomie e.V./ Pluralism in Economics Maastricht) Abstract: This paper investigates how the concept of public purpose is used in Modern Monetary Theory (MMT). As a common denominator among political scientists, the idea of public purpose is that economic actions should aim at benefiting the majority of the society. However, the concept is to be considered as an ideal of a vague nature, which is highly dependent on societal context and, hence, subject to change over time. MMT stresses that government spending plans should be designed to pursue a certain socio-economic mandate and not to meet any particular financial outcome. The concept of public purpose is heavily used in this theoretical body of thought and often referred to in the context of policy proposals as the ideas of universal job guarantee and banking reform proposals show. MMT scholars use the concept as a pragmatic benchmark against which policies can be assessed. With regards to the definition of public purpose, MMT scholars agree that it is dependent on the socio-cultural context. Nevertheless, MMT scholars view universal access to material means of survival as universally applicable and in that sense as the lowest possible common denominator. Keywords: Modern Monetary Theory, Public Purpose, Economy for the Common Good, Fiscal Policy, Monetary Policy Contacts: [email protected] [email protected] 2 1. Introduction While the concept of “public purpose” is widely discussed in political science and philosophy, it is hardly discussed at all in the orthodox school of the economics discipline.

  • Population Ageing and Inflation with Endogenous Money Creation
    Population Ageing and Inflation with Endogenous Money Creation Igor Fedotenkov DP 03/2016-013 Population ageing and inflation with endogenous money creation Igor Fedotenkov1 Bank of Lithuania Abstract This paper provides an explanation as to why population ageing is associ- ated with deflationary processes. For this reason we create an overlapping- generations model (OLG) with money created by credits (inside money) and intergenerational trade. In other words, we combine a neoclassical OLG model with post-Keynesian monetary theory. The model links demographic factors such as fertility rates and longevity to prices. We show that lower fertility rates lead to smaller demand for credits, and lower money creation, which in turn causes a decline in prices. Changes in longevity affect prices through real sav- ings and the capital market. Furthermore, a few links between interest rates and inflation are addressed, they arise in the general equilibrium and are not thoroughly discussed in literature. Long-run results are derived analytically; short-run dynamics are simulated numerically.

  • Inside-Money in the New Keynesian Model
    Inside-money in the New Keynesian model Cristina Manea∗ † December 4, 2019 Incomplete Draft Link to the latest version Abstract The textbook New Keynesian framework has become a common tool for monetary policy analysis in central banks. Policymakers are nonetheless often concerned that this framework abstracts away from endogenous money creation, and lacks realism. To address this concern, I introduce endogenous money creation by the private banking sector (like deposits), or “inside money”, into the textbook framework. I find that the new “inside money” model has the same equilibrium representation as the textbook ‘money-less” one, and hence transmission and optimal design of monetary policy in the two models are identical. Keywords: New Keynesian model, inside-money, cashless, inside-liquidity banking theory JEL Class.: E2 – E3– E4 ∗Universitat Pompeu Fabra. Email: [email protected]: https://www.upf.edu/web/econ/manea-cristina †I thank my PhD advisor Jordi Gali and Piti Disyatat for comments. 1 1 Introduction A number of economists have expressed concerns over the lack of explicit account of banks’ monetary role in New Keynesian models widely used for monetary policy analysis. These concerns are expressed on two dimensions. On a first dimension, they regard the monetary fundamentals of cashless versions of these models, because they do not explicitly model the role of bank deposits (’inside-money’) in transactions. For instance, Goodfriend and McCallum (2007) consider the New Keynesian framework in Bernanke, Gertler and Gilchrist (1999) as ’fundamentally non-monetary’ because ’it does not recognize the existence of a demand for money that serves to facilitate transactions’.

Introduction* Schumpeter (1954) has made the important distinction between ‘real analysis’ and ‘monetary analysis’. 1 In ‘real analysis’ the equilibrium values of employment, distribution and growth can be determined without any reference to monetary variables: Real Analysis proceeds from the principle that all essential phenomena of economic life are capable of being described in terms of goods and services, of decisions about them, and of relations between them. Money enters the picture only in the modest role of a technical device that has been adopted in order to facilitate transactions. This device can no doubt get out of order, and if it does it will indeed produce phenomena that are specifically attributable to its modus operandi. But so long as it functions normally, it does not affect the economic process, which behaves in the same way as it would in a barter economy: this is essentially what the concept of Neutral Money implies.

Its focus is on describing monetary and fiscal operations in nations that issue a sovereign currency. As such, it applies Georg Friedrich Knapp’s state money approach (chartalism), also adopted by John Maynard Keynes in his Treatise on Money. MMT emphasizes the difference between a sovereign currency issuer and a sovereign currency user with respect to issues such as fiscal and monetary policy space, ability to make all payments as they come due, credit worthiness, and insolvency. Following A. Mitchell Innes, however, MMT acknowledges some similarities between sovereign and nonsovereign issues of liabilities, and hence integrates a credit theory of money (or, “endogenous money theory,” as it is usually termed by post-Keynesians) with state money theory.

FMM Conference: The Euro at 20 – Macroeconomic Challenges Berlin, 24-26 October, 2019 Money supply is endogenous and the Venezuelan hyperinflation is a monetary phenomenon During the last years, Venezuela has experimented both a deep economic crisis and hyperinflation. The US economic blockade and the internal economic crisis has played a main role in the sharp fall of the output levels. But regarding hyperinflation, it must be analyzed as the result of the expansionary policies adopted by the government and the Central Bank in a context of currency overvaluation. In this research, I show the mechanisms that enabled this hyperinflation, which continues today, and explain how the approach to the Venezuelan hyperinflation as a 'monetary phenomenon' is fully consistent with the hypothesis of the endogenous supply of money.
