Class 12 Macro Economics — Definition, Functions, Evolution, Classification, and India's Monetary System

Introduction and Definition of Money

Money
Money is anything which is generally accepted as a medium of exchange, measure of value, store of value and means for standard of deferred payment. Money covers items like coins, currency notes, and cheques used for transactions and settling claims.

Cryptocurrency: Digital/virtual currency using cryptography. Decentralized, not controlled by central authority. In India, not recognized as legal tender.

Primary Functions of Money

The two most essential functions that define money — often called the primary functions:

Secondary Functions of Money

Beyond the primary functions, money also serves several secondary purposes:

Contingent and Dynamic Functions of Money

Contingent Functions — additional roles money plays in the economy:

Distribution of National Income

Money facilitates distribution of national income among factors of production — rent (land), wages (labor), interest (capital), profit (enterprise) — all expressed in monetary terms.

Static vs Dynamic Functions (per Paul Einzig):

AspectStatic FunctionsDynamic Functions
RoleHelp economy function smoothlyInfluence level of economic activity and trends
ExamplesMedium of exchange, measure of value, store of value, standard of deferred paymentsBasis for credit creation, liquidity leading to changes in income/output/employment/price levels
Without themEconomy cannot operateEconomy loses growth and adaptability

Evolution of Money

Money evolved through five distinct stages over thousands of years:

Classification of Money

Money is classified into three major categories based on the relationship between face value and intrinsic value:

Convertible Paper Money

Freely exchangeable for full-bodied money (gold/silver) at holder's option. Full backing not always necessary.

Inconvertible Paper Money

Cannot be converted into full-bodied money. Circulates based on government regulation and trust (e.g., Indian one-rupee note historically).

Token Coins

Metal value < face value (modern Indian coins ₹1, ₹2, ₹5, ₹10, ₹20).

Representative Token Money

100% backed and redeemable in gold/silver, but market value of commodity < paper's face value.

Circulating Promissory Notes

RBI notes — promises to pay bearer the stated sum; commodity value (as paper) much less than face value.

Demand Deposits in Banks

Withdrawn/transferred by cheque. Claims against the bank, not backed by bullion. Commodity value (of cheque) low vs transaction value.

Monetary System in India

Key features of the Indian monetary system:

Monetary Authority

Reserve Bank of India (RBI) manages the system.

Paper Currency Standard

India operates under Inconvertible Paper Currency Standard with 'rupee' as standard currency.

Legal Tender Rules

Coins = limited legal tender (small payments). Paper notes = unlimited legal tender (any amount).

Issuing Authority

RBI issues ₹2 and higher denomination notes. Ministry of Finance issues ₹1 notes and all coins.

Minimum Reserve System

RBI must maintain a minimum reserve of gold and foreign exchange worth ₹200 crores, based on which it can issue any amount of currency notes.

Titan Watch Example — Exam Relevance: Coins (₹1,200) — shopkeeper may refuse (limited legal tender max ₹1,000). Bank notes (₹1,200) — shopkeeper must accept (unlimited legal tender). Cheque — shopkeeper may refuse (non-legal tender).
