Functions of Money WHY NOT BARTER? I. HARD TO “CUT A DEAL” Text talk: Difficult to achieve a “double coincidence of wants” Meaning: barter is a clumsy, time-consuming, inefficient process. Barter is not very conducive to economic progress and development. Too much time spent in trading goods that should be spent in producing them. Q. What is meant by the phrase double coincidence of wants? A. Two conditions: 1. Each party must want what the other party has—forming the basis for a voluntary exchange 2. Each party must value the other’s good more than his/her own—else no voluntary exchange will occur AND HOW DOES MONEY HELP?? Money serves as a “medium of exchange” If money is generally acceptable in exchange for goods and services (which it is), then it makes it much easier to achieve that “double coincidence of wants”. By serving as a medium of exchange, money makes it easy to buy stuff. It facilitates voluntary exchange. It reduces “transactions costs”. It improves efficiency. II. With barter, it is very difficult to write contracts calling for future payment? How do you pay for something over time? And how does money help solve this problem? Money serves as a “standard for deferred payments” III. With barter, it is difficult to save in order to buy something in the future. What do you save? And again, how does money help? Money serves as a “store of value” Is money a good “store of value”? Are there other (nonmonetary) stores of value? Which is better? IV. With barter, it is difficult to express relative values/prices. For example, what is the value of a durian relative to the price of a banana? or a cantaloupe? With barter, it’s difficult to express relative prices. Money makes it easy. How? By serving as a “unit of account” Or a “standard of value” A common denominator of value .

Monetary Policy in Economies with Little or No Money Bennett T. McCallum NBER Working Paper No. 9838 July 2003 JEL No. E3, E4, E5 ABSTRACT The paper's arguments include: (1) Medium-of-exchange money will not disappear in the foreseeable future, although the quantity of base money may continue to decline. (2) In economies with very little money (e.g., no currency but bank settlement balances at the central bank), monetary policy will be conducted much as at present by activist adjustment of overnight interest rates. Operating procedures will be different, however, with payment of interest on reserves likely to become the norm. (3) In economies without any money there can be no monetary policy. The relevant notion of a general price level concerns some index of prices in terms of a medium of account.

Make sure you review the material pre- sented here and read the corresponding chapters on the textbook: Chapter 21 on Mankiw. • Barter. Exchange of one good or service for another. { Was the only method used until Lydians first used money (coins) in 700 B.C. Barter: Problems • Barter requires a double coincidence of wants. { Two people have to want each others goods or services. • People spend significant time searching for others to trade with. { Waste of scarce resources: time! • Money fixes the double coincidence of wants problem! The Three Functions of Money 1. Medium of exchange: Buyers give money to sellers when they want to purchase goods and services. • Solves the barter problems! 2. Unit of account: Makes measuring monetary value of goods and services easy. • Easy comparisons: $10 vs. $2000. 3. Store of value: You can hold onto your money today and spend it tomorrow: does not perish (except for inflation). 1 Lecture notes for Chapter #11 Prof. Bilen Two Types of Money 1. Commodity Money: Money that takes the form of a commodity with intrinsic value. • Intrinsic: has value even not used as money. • E.g. gold coins, cigarettes in prisons. 2. Fiat Money: Money without intrinsic value, used as money because of government decree. • E.g. the U.S. dollar. u Central Bank and Monetary Policy • Monetary system is the mechanism that provides money to a country's economy. { Where money comes from: the central bank! • Central bank is an institution that oversees the banking system and regulates the money supply.

  • Chapter 9 MONEY Q.1. What Is Barter?
    Chapter 9 MONEY Q.1. What is barter? Explain the difficulties of Barter system. Ans: Trade of goods with other goods without using money is called barter. This system was in practice before the invention of money. Following are the problems/difficulties of barter: • Lack of double coincidence of wants: The main difficulty of barter system is the lack of double coincidence of wants. In a barter system a person who wants to exchange his goods must find some person who is willing to exchange his commodity with his commodity. For example, a person possessed wheat, which he wanted to exchange for cloth. He could not succeed in acquiring cloth until he met someone who not only had cloth but was also willing to exchange with wheat. • Lack of store of value: The barter system suffered the lack of storing the value. There is no way of storing of wealth for a long period. Some commodities lose their value with the passage of time. Some commodities, such as milk, fish, vegetable, wheat, and cotton lose value with the passage of time. Such commodities could not store for a long period. • Lack of measure of value: It was very difficult to measure the value of the goods with other goods as we can measure the value of everything with the help of money today. Because, there was nothing that could measure the value of each good commonly. For example, it was difficult to tell how much milk should be given to get 1 kg of wheat. • Lack of transfer of value: In barter, people had been facing challenges in transferring wealth from one place to another due to heavy weight and size of the goods stored as wealth.

Economic phenomena also include other aspects of economic reality such as economic agents, (including corporations, individual producers and consumers), commodity markets, banks, investments, jobs and production. My investigation of the ontology of economic phenomena begins with a critical examination of the accounts of theorists and philosophers from the past, including Plato, Aristotle, Locke, Berkeley, Hume, Marx, Simmel and Menger.

  • Cryptocurrency: the Economics of Money and Selected Policy Issues
    Cryptocurrency: The Economics of Money and Selected Policy Issues Updated April 9, 2020 Congressional Research Service https://crsreports.congress.gov R45427 SUMMARY R45427 Cryptocurrency: The Economics of Money and April 9, 2020 Selected Policy Issues David W. Perkins Cryptocurrencies are digital money in electronic payment systems that generally do not require Specialist in government backing or the involvement of an intermediary, such as a bank. Instead, users of the Macroeconomic Policy system validate payments using certain protocols. Since the 2008 invention of the first cryptocurrency, Bitcoin, cryptocurrencies have proliferated. In recent years, they experienced a rapid increase and subsequent decrease in value. One estimate found that, as of March 2020, there were more than 5,100 different cryptocurrencies worth about $231 billion. Given this rapid growth and volatility, cryptocurrencies have drawn the attention of the public and policymakers. A particularly notable feature of cryptocurrencies is their potential to act as an alternative form of money. Historically, money has either had intrinsic value or derived value from government decree. Using money electronically generally has involved using the private ledgers and systems of at least one trusted intermediary. Cryptocurrencies, by contrast, generally employ user agreement, a network of users, and cryptographic protocols to achieve valid transfers of value. Cryptocurrency users typically use a pseudonymous address to identify each other and a passcode or private key to make changes to a public ledger in order to transfer value between accounts. Other computers in the network validate these transfers. Through this use of blockchain technology, cryptocurrency systems protect their public ledgers of accounts against manipulation, so that users can only send cryptocurrency to which they have access, thus allowing users to make valid transfers without a centralized, trusted intermediary.

  • New Monetarist Economics: Methods∗
    Federal Reserve Bank of Minneapolis Research Department Staff Report 442 April 2010 New Monetarist Economics: Methods∗ Stephen Williamson Washington University in St. Louis and Federal Reserve Banks of Richmond and St. Louis Randall Wright University of Wisconsin — Madison and Federal Reserve Banks of Minneapolis and Philadelphia ABSTRACT This essay articulates the principles and practices of New Monetarism, our label for a recent body of work on money, banking, payments, and asset markets. We first discuss methodological issues distinguishing our approach from others: New Monetarism has something in common with Old Monetarism, but there are also important differences; it has little in common with Keynesianism. We describe the principles of these schools and contrast them with our approach. To show how it works, in practice, we build a benchmark New Monetarist model, and use it to study several issues, including the cost of inflation, liquidity and asset trading. We also develop a new model of banking. ∗We thank many friends and colleagues for useful discussions and comments, including Neil Wallace, Fernando Alvarez, Robert Lucas, Guillaume Rocheteau, and Lucy Liu. We thank the NSF for financial support. Wright also thanks for support the Ray Zemon Chair in Liquid Assets at the Wisconsin Business School. The views expressed herein are those of the authors and not necessarily those of the Federal Reserve Banks of Richmond, St. Louis, Philadelphia, and Minneapolis, or the Federal Reserve System. 1Introduction The purpose of this essay is to articulate the principles and practices of a school of thought we call New Monetarist Economics. It is a companion piece to Williamson and Wright (2010), which provides more of a survey of the models used in this literature, and focuses on technical issues to the neglect of methodology or history of thought.

  • Money As 'Universal Equivalent' and Its Origins in Commodity Exchange
    MONEY AS ‘UNIVERSAL EQUIVALENT’ AND ITS ORIGIN IN COMMODITY EXCHANGE COSTAS LAPAVITSAS DEPARTMENT OF ECONOMICS SCHOOL OF ORIENTAL AND AFRICAN STUDIES UNIVERSITY OF LONDON [email protected] MAY 2003 1 1.Introduction The debate between Zelizer (2000) and Fine and Lapavitsas (2000) in the pages of Economy and Society refers to the conceptualisation of money. Zelizer rejects the theorising of money by neoclassical economics (and some sociology), and claims that the concept of ‘money in general’ is invalid. Fine and Lapavitsas also criticise the neoclassical treatment of money but argue, from a Marxist perspective, that ‘money in general’ remains essential for social science. Intervening, Ingham (2001) finds both sides confused and in need of ‘untangling’. It is worth stressing that, despite appearing to be equally critical of both sides, Ingham (2001: 305) ‘strongly agrees’ with Fine and Lapavitsas on the main issue in contention, and defends the importance of a theory of ‘money in general’. However, he sharply criticises Fine and Lapavitsas for drawing on Marx’s work, which he considers incapable of supporting a theory of ‘money in general’. Complicating things further, Ingham (2001: 305) also declares himself ‘at odds with Fine and Lapavitsas’s interpretation of Marx’s conception of money’. For Ingham, in short, Fine and Lapavitsas are right to stress the importance of ‘money in general’ but wrong to rely on Marx, whom they misinterpret to boot. Responding to these charges is awkward since, on the one hand, Ingham concurs with the main thrust of Fine and Lapavitsas and, on the other, there is little to be gained from contesting what Marx ‘really said’ on the issue of money.

  • Nominality of Money: Theory of Credit Money and Chartalism Atsushi Naito
    Review of Keynesian Studies Vol.2 Atsushi Naito Nominality of Money: Theory of Credit Money and Chartalism Atsushi Naito Abstract This paper focuses on the unit of account function of money that is emphasized by Keynes in his book A Treatise on Money (1930) and recently in post-Keynesian endogenous money theory and modern Chartalism, or in other words Modern Monetary Theory. These theories consider the nominality of money as an important characteristic because the unit of account and the corresponding money as a substance could be anything, and this aspect highlights the nominal nature of money; however, although these theories are closely associated, they are different. The three objectives of this paper are to investigate the nominality of money common to both the theories, examine the relationship and differences between the two theories with a focus on Chartalism, and elucidate the significance and policy implications of Chartalism. Keywords: Chartalism; Credit Money; Nominality of Money; Keynes JEL Classification Number: B22; B52; E42; E52; E62 122 Review of Keynesian Studies Vol.2 Atsushi Naito I. Introduction Recent years have seen the development of Modern Monetary Theory or Chartalism and it now holds a certain prestige in the field. This theory primarily deals with state money or fiat money; however, in Post Keynesian economics, the endogenous money theory and theory of monetary circuit place the stress on bank money or credit money. Although Chartalism and the theory of credit money are clearly opposed to each other, there exists another axis of conflict in the field of monetary theory. According to the textbooks, this axis concerns the functions of money, such as means of exchange, means of account, and store of value.

  • Central Bank Digital Currency in Historical Perspective: Another Crossroad in Monetary History1
    Central Bank Digital Currency in Historical Perspective: Another Crossroad in Monetary History1 Michael D. Bordo, Rutgers University, NBER and Hoover Institution, Stanford University Economics Working Paper 21113 HOOVER INSTITUTION 434 GALVEZ MALL STANFORD UNIVERSITY STANFORD, CA 94305-6010 July 14, 2021 Digitalization of Money is a crossroad in monetary history. Advances in technology has led to the development of new forms of money: virtual (crypto) currencies like bitcoin; stable coins like libra/diem; and central bank digital currencies (CBDC) like the Bahamian sand dollar. These innovations in money and finance have resonance to earlier shifts in monetary history: 1) The shift in the eighteenth and nineteenth century from commodity money (gold and silver coins) to convertible fiduciary money and inconvertible fiat money; 2) the shift in the nineteenth and twentieth centuries from central bank notes to a central bank monopoly;3) Then evolution since the seventeenth century of central banks and the tools of monetary policy. This paper makes the case for CBDC through the lens of monetary history. The bottom line is that the history of transformations in monetary systems suggests that technical change in money is inevitably driven by the financial incentives of a market economy. Government has always had a key role in the provision of outside money, which is a public good. Government has also regulated inside money provided by the private sector. This held for fiduciary money and will likely hold for digital money. CBDC could make monetary policy more efficient, and it could transform the international monetary and payments systems. Keywords: digitalization, financial innovation, evolution, central banks, monetary policy, international payments JEL Codes: E5, F4, N2.
