Definition Of Money By Different Economists

Definition of Money by Adam Smith

Adam Smith, often considered the father of modern economics, provided a broad standard definition of money. He focused on its function as a medium of exchange simplifying transactions by providing a common measure of value.

Adam Smith’s Standard Definition of Money

Smith famously defined money by its use. In his seminal work “The Wealth of Nations,” he wrote, “By means of [money] the whole revenue of the society is regularly distributed among all its different members.” This implies that money is not a representation of wealth itself; instead, it is a tool that facilitates the distribution and flow of wealth among individuals and entities within a society.

Smith’s Function and Role of Money

For Adam Smith, money played a pivotal role in facilitating economic transactions. He suggested that money, acting as a common measure of value, eliminated the inefficiencies of the barter system. It provides a standard of deferred payments, making it easier for individuals to plan for and negotiate future purchases or contracts.

Significance of Adam Smith’s Definition

The significance of Adam Smith’s definition of money lies in its simplicity and its focus on the practical, everyday use of money. Smith did not tie money to any specific material or object, which highlights its essence as an enabler of exchange and a measure of relative worth. The universality and timelessness of his definition have made it a cornerstone in the field of economics.

Definition of Money by Karl Marx

In contrast to Adam Smith’s view, Karl Marx, the father of Marxism, saw money as a manifestation of social relations. He saw the economic value as something derived from labor and viewed money as a tool of capitalism that influenced production and controlled the working class.

Marx’s View of Money as Social Relations

Marx suggested that money was more than a mere tool or commodity. He argued that money, in its essence, crystallized social relations and reflected the class dynamics within a capitalist society. Marx saw money as a form of social power, which allowed a select few (the bourgeoisie) to control the means of production and exert influence over the proletariat.

Marx’s Analysis of Money’s Influence on Production

Marx also examined how money influenced production under capitalism. He believed that the capitalist pursuit of profit led to exploitation of labor. Money acted as a motivator for capitalists, driving them to control production process and extract surplus value from the proletariat’s labor.

Impact of Marx’s Money Theory on Economics

Marx’s theory challenged the prevailing economic norms and still continues to influence important debates around wealth inequality, labor rights, and capital accumulation. His examination of money from a socio-political perspective provided fresh insights that stimulated discourse on labor exploitation and class struggle.

Definition of Money by John Maynard Keynes

John Maynard Keynes, a prominent economist of the 20th Century, emphasized the demand for money. He brought attention to its role in influencing people’s spending and investment decisions, affecting overall economic stability.

Keynes’ Theory of Money Demand

In Keynes’ “General Theory,” he explored the idea that people hold money for three reasons: for transactions, for precaution against uncertainty, and for speculative purposes. He argued that the speculative demand for money becomes more important during economic instability, which can lead to a decrease in investment and subsequently a decrease in employment and income levels.

The Role of Money in Keynesian Economics

Money occupies a central role in Keynesian economics. Keynesian theories suggest that money can be used as a policy tool to manage economic fluctuations. Changes in money supply can influence interest rates, which in turn can stimulate or slow economic activity.

Understanding Keynes’ Liquidity Preference

Liquidity preference is a core concept in Keynes’ theory. It implies that individuals prefer to hold liquid money rather than illiquid assets like bonds. In times of economic instability, liquidity preference increases, and this heightened demand for money can lead to rising interest rates and a downturn in economic activity.

Definition Of Money By Different Economists

Definition of Money by Milton Friedman

Milton Friedman, a key proponent of monetarism, emphasized the role of money supply in determining the price level and thus the rate of inflation.

Friedman’s Quantity Theory of Money

Friedman’s Quantity Theory of Money posits that there is a direct relationship between the money supply and price level in an economy. According to Friedman, if the money supply increases faster than the level of production, inflation will result, thereby devaluing the money.

Friedman’s View on Money Supply and Inflation

Friedman believed that inflation is always a monetary phenomenon. A rampant increase in money supply without a proportional increase in output leads to inflation. For Friedman, maintaining a steady growth rate of the money supply is crucial to curb inflation and ensure stability.

Friedman’s Monetary Rule

Friedman’s proposed “monetary rule” recommended that central banks increase the money supply at a constant annual rate. This rule underlines his theory that a steady, predictable increase in money supply could potentially avoid the economic fluctuations caused by unpredictable monetary policies.

Definition of Money by Friedrich Hayek

Friedrich Hayek, a staunch supporter of the free market, saw money in the context of free market systems. He was also a vocal critic of the conventional central banking systems.

Hayek’s View on Money and Free Market

For Hayek, money was a product of the free market. He believed that the competitive process in a free market system would naturally lead to the development of a medium of exchange that is widely accepted – money.

Hayek’s Criticism of Central Banking System

Hayek criticized the monopolization of money creation through central banking. He argued that this led to economic instability and market distortions, particularly through the artificial manipulation of interest rates.

The Relevance of Hayek’s Theory in Modern Economics

Hayek’s theories, especially his support for free-market competition in money creation, have found renewed relevance in today’s era of digital currencies and decentralization. His views continue to inspire debates on the role of central banks and the potential benefits of competitive money supply systems.

Definition of Money by Irving Fisher

Irving Fisher, one of the earliest American economists, looked at money through the lens of its velocity and its role in transactions.

Fisher’s Transaction Equation and Money

Fisher’s Transaction Equation (MV=PT) sees money in terms of its velocity (V) and the price level (P) and quantity of transactions (T). The equation proposes that the total amount of spending in an economy (PT) is equal to the total money supply (M) multiplied by the speed (V) at which money changes hands.

Fisher’s View on Money Velocity

Fisher suggested that under normal economic conditions, the velocity of money was fairly stable. Therefore, changes in the money supply had a direct and proportional impact on the level of prices in an economy.

The Impact of Fisher’s Theory on Monetary Policy

Fisher’s theories played a significant role in shaping monetary policies over the years. His emphasis on stable money supply and controlled inflation has informed the actions of central banks globally, reinforcing the idea that managing the money supply is key to maintaining economic stability.

Definition of Money by Ludwig von Mises

Ludwig von Mises, a proponent of the Austrian School of Economics, put forward the regression theorem, which explains the origin of money’s value, and argued heavily against inflationary policies.

Mises’ Regression Theorem of Money

The Regression Theorem states that the value of money at present is based on the expected value of money in the future, which, in turn, is based on the historical value of money. Essentially, the theorem implies that money derives its value from its past usefulness as a medium of exchange.

Mises’ Criticism of Inflationary Policy

Mises was a strong critic of inflationary policies of central banks. He argued that increasing the supply of money at a rate higher than economic growth leads to distortion of market signals, leading to misallocation of resources and economic recession.

Understanding Mises’ Austrian School of Economics

Mises’ Austrian School of Economics promotes a free-market based view of money and denounces government interference via inflationary monetary policy. This School encourages the understanding of individual choices and spontaneous order as instrumental in shaping the economy.

Definition of Money by David Ricardo

David Ricardo, an influential classical economist, connected the concept of money with that of commodities. He staunchly supported the gold standard as a stable basis for a monetary system.

Ricardo’s Theory of Money and Commodity

For Ricardo, money was fundamentally a commodity chosen to facilitate exchange. He saw it as neutral in terms of influencing economic output but considered its role vital in simplifying transactions and reducing the friction of a barter system.

Ricardo’s View on Gold Standard

Ricardo was a firm believer in the gold standard. He contended that money should represent a fixed quantity of a commodity like gold. Such a standard would prevent irresponsible government overspending and inflation and would foster international trade.

Ricardo’s Influence on Monetary Theory

Ricardo’s theories greatly shaped the classical understanding of money that prevailed throughout the 19th and early 20th centuries. Though the gold standard has largely been abandoned now, his views on government responsibility and fiscal discipline remain influential in contemporary economic thought.

Definition of Money by J.M. Robertson

J.M. Robertson, an often-overlooked economist, put forward theories relating to monetary policy and the influence of money supply on economic activity.

Robertson’s Theory of Monetary Policy

Robertson believed in the power of monetary policy to impact economic activity. He suggested that by manipulating the money supply, governments could control spending in the economy, thereby either stimulating growth or keeping inflation in check.

Robertson’s View on Money Supply and Economic Activity

Robertson proposed that changes in the money supply would directly affect the rate of spending in an economy. Hence, increases in the money supply could lead to more spending and economic growth, while reductions in the supply could slow down the economy.

Analysis of Robertson’s Monetary Theory

Robertson’s theories, although less known, provide a crucial understanding of how changes in the money supply can impact economic activity. His views complement and provide a context for many of the prevailing theories related to the role of money in macroeconomics.

Definition of Money by Alfred Marshall

Alfred Marshall, a key figure in neoclassical economics, introduced the concept of ‘money-in-utility function’. He distinguished between real money (adjusted for inflation) and nominal money (the face value).

Marshall’s Money-in-Utility Function

Marshall introduced money directly into the utility function, a step towards integrating monetary theory with value theory. He portrayed the use of money as bringing satisfaction just by holding it, referring to its use as a store of wealth.

Marshall’s Conceptualisation of Real and Nominal Money

Marshall made a crucial distinction between nominal money and real money. He suggested that the face value of money (nominal) was less significant than its purchasing power (real), emphasizing the impact of inflation on money’s ability to purchase goods and services.

Marshall’s Contribution to Monetary Economics

Marshall’s contributions have profoundly impacted economic understanding of money and its functions. His theories helped to systematically incorporate money into economic models, paving the way for robust monetary policies and adding depth to the overall understanding of monetary economics.
