Background
Money supply, also known as the money stock, refers to the total amount of monetary assets available in an economy at a particular point in time. It includes various forms of money, such as cash, coins, and balances held in checking and savings accounts.
Historical Context
The concept of money supply has evolved over time. Initially, money constituted primarily of precious metals such as gold and silver. With the advent of banking systems and financial intermediaries, the definition of money expanded to include bank deposits, liquid assets, and similar forms of financial instruments.
Definitions and Concepts
The money supply is the total amount of money available in an economy. This can include:
- Legal tender: Notes and coins that are officially recognized and accepted for financial transactions.
- Bank deposits: Funds held in accounts that can be withdrawn on demand.
- Other liquid assets: Various types of deposits in non-bank financial intermediaries like building societies and forms of highly liquid securities.
Major Analytical Frameworks
Classical Economics
Classical economists emphasized the quantity theory of money, where money supply directly impacts price levels. An increase in money supply, without a corresponding increase in goods and services, leads to inflation.
Neoclassical Economics
This school expanded on the classical view, considering also the velocity of money and other factors affecting money supply. They generally believe in the neutrality of money in the long-run but acknowledge short-term effects.
Keynesian Economics
Keynesians argue that changes in money supply affect real variables like output and employment in the short run, especially under conditions where interest rates are low and the economy is near or at full employment.
Marxian Economics
While not heavily focused on the money supply, Marxian economics views money as a tool of capital, influencing economic relations and power structures in society.
Institutional Economics
Institutional economists study the money supply within the framework of institutions, laws, and norms that affect its circulation and usage in the economy.
Behavioral Economics
Behavioral economists explore how psychological factors and cognitive biases influence people’s use of money and their response to changes in the money supply.
Post-Keynesian Economics
Post-Keynesians put a strong emphasis on the endogeneity of money supply and argue that money supply is driven by the demand for bank credit.
Austrian Economics
Austrians critique central banking and advocate for free-market mechanisms to determine money supply, often favoring commodity-backed currencies.
Development Economics
Development economists analyze money supply in the context of developing economies, focusing on its role in fostering economic growth, stability, and poverty alleviation.
Monetarism
Monetarists, led by Milton Friedman, assert that controlling money supply is the key mechanism for controlling inflation. They advocate for a fixed annual increase in money supply to maintain price stability.
Comparative Analysis
Different schools of thought emphasize various aspects of the money supply. Classical and Monetarist frameworks highlight the relationship between money supply and price levels, whereas Keynesians and Post-Keynesians focus on how money supply impacts short-term economic activity.
Case Studies
An analysis of historical case studies, such as the hyperinflation in Zimbabwe or the deflationary period in Japan, reveals how deviations in money supply practices can lead to significant economic consequences.
