This paper relates Keynes’s discussions of money, the state theory of money, financial markets, investors’ expectations, uncertainty, and liquidity preference to the dynamics of government bond yields for countries with monetary sovereignty. Keynes argued that the central bank can influence the long-term interest rate on government bonds and the shape of the yield curve mainly through the short-term interest rate. Investors’ psychology, herding behavior in financial markets, and uncertainty about the future reinforce the effects of the short-term interest rate and the central bank’s monetary policy actions on the long-term interest rate. Several recent empirical studies that examine the dynamics of government bond yields substantiate the Keynesian perspective that the long-term interest rate responds markedly to the short-term interest rate. These empirical studies not only vindicate the Keynesian perspective but also have relevance for macroeconomic theory and policy.

Modern money theory (MMT) synthesizes several traditions from heterodox economics. 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. MMT uses this integration in policy analysis to address issues such as exchange rate regimes, full employment policy, financial and economic stability, and the current challenges facing modern economies: rising inequality, climate change, aging of the population, tendency toward secular stagnation, and uneven development. This paper will focus on the development of the “Kansas City” approach to MMT at the University of Missouri–Kansas City (UMKC) and the Levy Economics Institute of Bard College.

Money, in this paper, is defined as a power relationship of a specific kind, a stratified social debt relationship, measured in a unit of account determined by some authority. A brief historical examination reveals its evolving nature in the process of social provisioning. Money not only predates markets and real exchange as understood in mainstream economics but also emerges as a social mechanism of distribution, usually by some authority of power (be it an ancient religious authority, a king, a colonial power, a modern nation state, or a monetary union). Money, it can be said, is a “creature of the state” that has played a key role in the transfer of real resources between parties and the distribution of economic surplus.

In modern capitalist economies, the currency is also a simple public monopoly. As long as money has existed, someone has tried to tamper with its value. A history of counterfeiting, as well as that of independence from colonial and economic rule, is another way of telling the history of “money as a creature of the state.” This historical understanding of the origins and nature of money illuminates the economic possibilities under different institutional monetary arrangements in the modern world. We consider the so-called modern “sovereign” and “nonsovereign” monetary regimes (including freely floating currencies, currency pegs, currency boards, dollarized nations, and monetary unions) to examine the available policy space in each case for pursuing domestic policy objectives.

The Unit of Account, Inflation, Leverage, and Financial Fragility

We hope to model financial fragility and money in a way that captures much of what is crucial in Hyman Minsky’s financial fragility hypothesis. This approach to modeling Minsky may be unique in the formal Minskyan literature. Namely, we adopt a model in which a psychological variable we call financial prudence (P) declines over time following a financial crash, driving a cyclical buildup of leverage in household balance sheets. High leverage or a low safe-asset ratio in turn induces high financial fragility (FF). In turn, the pathways of FF and capacity utilization (u) determine the probabilistic risk of a crash in any time interval. When they occur, these crashes entail discrete downward jumps in stock prices and financial sector assets and liabilities. To the endogenous government liabilities in Hannsgen (2014), we add common stock and bank loans and deposits. In two alternative versions of the wage-price module in the model (wage–Phillips curve and chartalist, respectively), the rate of wage inflation depends on either unemployment or the wage-setting policies of the government sector. At any given time t, goods prices also depend on endogenous markup and labor productivity variables. Goods inflation affects aggregate demand through its impact on the value of assets and debts. Bank rates depend on an endogenous markup of their own. Furthermore, in light of the limited carbon budget of humankind over a 50-year horizon, goods production in this model consumes fossil fuels and generates greenhouse gases.

The government produces at a rate given by a reaction function that pulls government activity toward levels prescribed by a fiscal policy rule. Subcategories of government spending affect the pace of technical progress and prudence in lending practices. The intended ultimate purpose of the model is to examine the effects of fiscal policy reaction functions, including one with dual unemployment rate and public production targets, testing their effects on numerically computed solution pathways. Analytical results in the penultimate section show that (1) the model has no equilibrium (steady state) for reasons related to Minsky’s argument that modern capitalist economies possess a property that he called “the instability of stability,” and (2) solution pathways exist and are unique, given vectors of initial conditions and parameter values and realizations of the Poisson model of financial crises.

The Contributions of John F. Henry

This paper explores the rise of money and class society in ancient Greece, drawing historical and theoretical parallels to the case of ancient Egypt. In doing so, the paper examines the historical applicability of the chartalist and metallist theories of money. It will be shown that the origins and the evolution of money were closely intertwined with the rise and consolidation of class society and inequality. Money, class society, and inequality came into being simultaneously, so it seems, mutually reinforcing the development of one another. Rather than a medium of exchange in commerce, money emerged as an “egalitarian token” at the time when the substance of social relations was undergoing a fundamental transformation from egalitarian to class societies. In this context, money served to preserve the façade of social and economic harmony and equality, while inequality was growing and solidifying. Rather than “invented” by private traders, money was first issued by ancient Greek states and proto-states as they aimed to establish and consolidate their political and economic power. Rather than a medium of exchange in commerce, money first served as a “means of recompense” administered by the Greek city-states as they strived to implement the civic conception of social justice. While the origins of money are to be found in the origins of inequality, a well-functioning democratic society has the power to subvert the inequality-inducing characteristic of money via the use of money for public purpose, following the principles of Modern Money Theory (MMT). When used according to the principles of MMT, the inequality-inducing characteristic of money could be undermined, while the current trends in rising income and wealth disparities could be contained and reversed. 

The Advantages of Owning the Magic Porridge Pot

Over the past two decades there has been a revival of Georg Friedrich Knapp’s “state money” approach, also known as chartalism. The modern version has come to be called Modern Money Theory. Much of the recent research has delved into three main areas: mining previous work, applying the theory to analysis of current sovereign monetary operations, and exploring the policy space open to sovereign currency issuers. This paper focuses on “outside” money—the currency issued by the sovereign—and the advantages that accrue to nations that make full use of the policy space provided by outside money.

An Alternative to Economic Orthodoxy

This paper explores the intellectual history of the state, or chartalist, approach to money, from the early developers (Georg Friedrich Knapp and A. Mitchell Innes) through Joseph Schumpeter, John Maynard Keynes, and Abba Lerner, and on to modern exponents Hyman Minsky, Charles Goodhart, and Geoffrey Ingham. This literature became the foundation for Modern Money Theory (MMT). In the MMT approach, the state (or any other authority able to impose an obligation) imposes a liability in the form of a generalized, social, legal unit of account—a money—used for measuring the obligation. This approach does not require the preexistence of markets; indeed, it almost certainly predates them. Once the authorities can levy such obligations, they can name what fulfills any obligation by denominating those things that can be delivered; in other words, by pricing them. MMT thus links obligatory payments like taxes to the money of account as well as the currency. This leads to a revised view of money and sovereign finance. The paper concludes with an analysis of the policy options available to a modern government that issues its own currency.

The United States must make a fundamental choice in its economic policy in the next few months, a choice that will shape the US economy for years to come. Pundits and policymakers are divided over how to address what is widely referred to as the “fiscal cliff,” a combination of tax increases and spending cuts that will further weaken the domestic economy. Will the United States continue its current, misguided, policy of implementing European-style austerity measures, and the economic contraction that is the inevitable consequence of such policies? Or will it turn aside from the fiscal cliff, using a combination of its sovereign currency system and Keynesian fiscal policy to strengthen aggregate demand?

Our analysis presents a model of what we call the “fiscal trap”—a self-imposed spiral of economic contraction resulting from a fundamental misunderstanding of the role and function of fiscal policy in times of economic weakness. Within this framework, we begin our analysis with the disastrous results of austerity policies in the European Union (EU) and the UK. Our account of these policies and their results is meant as a cautionary tale for the United States, not as a model.

Recently, some have wondered whether a fiscal stimulus plan could reduce the government’s budget deficit. Many also worry that fiscal austerity plans will only bring higher deficits. Issues of this kind involve endogenous changes in tax revenues that occur when output, real wages, and other variables are affected by changes in policy. Few would disagree that various paradoxes of austerity or stimulus might be relevant, but such issues can be clarified a great deal with the help of a complete heterodox model.

In light of recent world events, this paper seeks to improve our understanding of the dynamics of fiscal policy and financial crises within the context of two-dimensional (2D) and five-dimensional heterodox models. The nonlinear version of the 2D model incorporates curvilinear functions for investment and consumption out of unearned income. To bring in fiscal policy, I make use of a rule with either (1) dual targets of capacity utilization and public production, or (2) a balanced-budget target. Next, I add discrete jumps and policy-regime switches to the model in order to tell a story of a financial crisis followed by a move to fiscal austerity. Then, I return to the earlier model and add three more variables and equations: (1) I model the size of the private- and public-sector labor forces using a constant growth rate and account for their social reproduction by introducing an unemployment-insurance scheme; and (2) I make the markup endogenous, allowing its rate of change to depend, in a possibly nonlinear way, on capacity utilization, the real wage relative to a fixed norm, the employment rate, profitability, and the business sector’s desired capital-stock growth rate. In the conclusion, I comment on the implications of my results for various policy issues.

This paper takes off from Jan Kregel’s paper “Shylock and Hamlet, or Are There Bulls and Bears in the Circuit?” (1986), which aimed to remedy shortcomings in most expositions of the “circuit approach.” While some “circuitistes” have rejected John Maynard Keynes’s liquidity preference theory, Kregel argued that such rejection leaves the relation between money and capital asset prices, and thus investment theory, hanging. This paper extends Kregel’s analysis to an examination of the role that banks play in the circuit, and argues that banks should be modeled as active rather than passive players. This also requires an extension of the circuit theory of money, along the lines of the credit and state money approaches of modern Chartalists who follow A. Mitchell Innes. Further, we need to take Charles Goodhart’s argument about default seriously: agents in the circuit are heterogeneous credit risks. The paper concludes with links to the work of French circuitist Alain Parguez.

Rethinking Money as a Public Monopoly

In this paper I first provide an overview of alternative approaches to money, contrasting the orthodox approach, in which money is neutral, at least in the long run; and the Marx-Veblen-Keynes approach, or the monetary theory of production. I then focus in more detail on two main categories: the orthodox approach that views money as an efficiency-enhancing innovation of markets, and the Chartalist approach that defines money as a creature of the state. As the state’s “creature,” money should be seen as a public monopoly. I then move on to the implications of viewing money as a public monopoly and link that view back to Keynes, arguing that extending Keynes along these lines would bring his theory up to date.

This paper begins by defining, and distinguishing between, money and finance, and addresses alternative ways of financing spending. We next examine the role played by financial institutions (e.g., banks) in the provision of finance. The role of government as both regulator of private institutions and provider of finance is also discussed, and related topics such as liquidity and saving are explored. We conclude with a look at some of the new innovations in finance, and at the global financial crisis, which could be blamed on excessive financialization of the economy.
