Comprehensive Notes on Monetary and Fiscal Policy

Functions and Kinds of Money

• Functions of Money: Money serves three primary roles in the economy:     * Medium of Exchange: An item that buyers provide to sellers as a means of payment when they wish to purchase goods and services.     * Unit of Account: The standard yardstick or numerical scale people use to post prices and record debts.     * Store of Value: An item that people can use to transfer purchasing power from the present to the future.

• Liquidity: This is defined as the ease with which an asset can be converted into the economy’s medium of exchange.

• The Kinds of Money:     * Commodity Money: This takes the form of a commodity that possesses intrinsic value. Examples include gold, silver, and cigarettes.     * Fiat Money: This is used as money because of government decree or mandate. It does not possess intrinsic value. Examples include coins, currency, and check deposits.

Measuring the Quantity of Money

• Money Stock: The quantity of money circulating in the economy. It is represented by the formula: $M = C + D$

• Currency ($C$): The paper bills and coins currently in the hands of the public.

• Demand Deposits ($D$): Balances in bank accounts that depositors can access on demand by writing a check.

• Money in the U.S. Economy (Data from Copyright)2003 Southwestern/Thomson Learning):     * Currency: $580 billion.     * M1 components ($1,179 billion): Includes currency, demand deposits, traveler’s checks, and other checkable deposits ($599 billion).     * M2 components ($5,455 billion): Includes everything in M1 plus savings deposits, small time deposits, money market mutual funds, and a few minor categories ($4,276 billion).

• Monetary System Supply Measures (General/RBI Context):     * C: Currency held by the public.     * M1: Currency with the public + demand deposits with the banks + other deposits with the RBI (RBI context focuses on short-term demand deposits).     * M2: M1 + short-term time deposits + certificate of deposit (CDs).     * M3: M2 + long-term time deposits + term funding from financial institutions (referred to as "broad money supply").

The Central Bank and Regulatory Structure

• The Central Bank Role: Designed to oversee the banking system and regulate the quantity of money in the economy.

• The Federal Reserve System (U.S.):     * Structure: Primary elements include the Board of Governors, the Regional Federal Reserve Banks, and the Federal Open Market Committee (FOMC).     * The Federal Open Market Committee (FOMC): Serves as the main policy-making organ for the Fed. It meets approximately every six weeks to review the state of the economy.     * Monetary Policy: Conducted by the FOMC, it involves the setting of the money supply (the quantity of money available in the economy) by central bank policymakers.

• Reserve Bank of India (RBI):     * Central Board of Directors: The top of the organizational structure, appointed by the Government under the Reserve Bank of India Act, 1934. It has primary authority for RBI oversight and delegates functions to Local Boards and committees.     * Chief Executive: The Governor supervises and directs RBI affairs, supported by Deputy Governors and Executive Directors.     * Local Boards: Four boards (Western, Eastern, Northern, and Southern) located in Mumbai, Kolkata, New Delhi, and Chennai.     * Offices and Branches: Units in the four metros (Mumbai, Kolkata, Delhi, Chennai) are "offices"; units in other cities are "branches." Currently, the RBI operates at 34 locations in India.     * Supervisory Boards: Includes the Board for Financial Supervision and the Board for Regulation and Supervision of Payment and Settlement Systems.

Banks and the Money Supply

• Three Primary Functions of the Central Bank:     * Regulates banks to ensure adherence to safe/sound banking laws.     * Acts as a banker’s bank, making loans to banks and serving as a lender of last resort.     * Conducts monetary policy by controlling the money supply.

• Open Market Operations: The primary method for adjusting money supply involves the purchase or sale of government bonds.     * To increase supply: The central bank creates dollars to purchase government bonds from the public.     * To decrease supply: The central bank sells government bonds from its portfolio to the public, removing money from circulation.

• Bank Reserve Systems:     * Reserves: Deposits that banks have received but have not loaned out.     * 100-percent-reserve banking: A system where banks hold all deposits as reserves. In this system, if assets (reserves) and liabilities (deposits) both equal $100.00, the money supply is unchanged by the bank's creation.     * Fractional-reserve banking: A system where banks hold only a fraction of deposits as reserves and lend out the remainder.     * Reserve Ratio ($rr$): The fraction of deposits that banks hold as reserves. If First National Bank has a 10% reserve ratio on a $100 deposit, it holds $10.00 in reserves and lends $90.00. The money supply then becomes $190 ($100 demand deposit + $90 currency held by the borrower).

• Money Creation: When banks hold only a fraction of deposits in reserve, they create money. Note that this creates debt alongside the new money; it does not create new wealth.

The Money Multiplier

• The Process: Money creation continues as loans from one bank are redeposited into another. For example, if Second National Bank receives the $90 from the first loan and has a 10% reserve ratio, it keeps $9.00 and lends $81.00.

• Total Money Supply Calculation:     * Original deposit: $100.00     * First National lending: $90.00 (calculated as $0.9 \times 100.00$)     * Second National lending: $81.00 (calculated as $0.9 \times 90.00$)     * Third National lending: $72.90 (calculated as $0.9 \times 81.00$)     * Total eventually created: $1,000.00

• Mathematical Formula: The multiplier ($M$) is the reciprocal of the reserve ratio ($R$ or $rr$):     * $M = \frac{1}{rr}$     * Calculation: $100 \times (1 + (1-rr) + (1-rr)^2 + \dots) = \frac{100}{rr}$     * Using the sum of geometric series where $x = 1 - rr$: $1 + x + x^2 + x^3 + x^4 + \dots = \frac{1}{1-x}$     * $\frac{1}{1-(1-rr)} = \frac{1}{rr}$     * If $rr = 10\%$, then the multiplier is $10$. If $rr = 20\%$, the multiplier is $5$.

Tools of Monetary Control

• Open-Market Operations: Buying bonds increases the money supply; selling bonds decreases it.

• Reserve Requirements: Regulations on the minimum reserves banks must hold against deposits.     * Increasing the requirement decreases the money supply.     * Decreasing the requirement increases the money supply.

• Discount Rate (Bank Rate): The interest rate the central bank charges commercial banks for loans.     * Increasing the rate decreases the money supply.     * Decreasing the rate increases the money supply.

• India-Specific Instruments:     * Cash Reserve Ratio (CRR): The proportion of net demand and time liabilities banks must keep as cash with the RBI.     * Statutory Liquidity Ratio (SLR): The amount banks must invest in government-issued securities.     * Repo Rate: The rate at which the RBI lends to commercial banks (injects liquidity).     * Reverse Repo Rate: The rate at which the RBI borrows from commercial banks (absorbs liquidity).

• Operational Limitations: Control is not precise because the central bank does not control the amount of money households choose to hold as deposits or the amount bankers choose to lend.

Classical Theory of Inflation

• Definitions:     * Inflation: An increase in the overall level of prices.     * Hyperinflation: An extraordinarily high rate of inflation (exceeding 50% per month).

• Value of Money: If the price level is $P$, the value of money is $\frac{1}{P}$. If $P = 100$, then $1$ unit of currency buys $\frac{1}{100}$ of a basket of goods. As $P$ increases, $\frac{1}{P}$ decreases.

• Monetary Equilibrium: In the long run, the price level adjusts to where money demand equals money supply.     * Money Supply: Fixed by the Fed, appearing as a vertical (perfectly inelastic) line on a graph.     * Money Demand: Reflects how much liquid wealth people want to hold; determined largely by the price level. Higher prices lead to higher money demand.

• Monetary Injection: An increase in money supply decreases the value of money and increases the price level.

• Quantity Theory of Money: Asserts that the quantity of money available determines the price level, and the growth rate of money determines the inflation rate.

The Classical Dichotomy and Monetary Neutrality

• Variable Classification:     * Nominal Variables: Measured in monetary units (e.g., dollar prices).     * Real Variables: Measured in physical units (e.g., production, real GDP, real wages, real interest rates).

• Classical Dichotomy: The theoretical separation of nominal and real variables. Relative prices are considered real because they are not measured in money terms.

• Monetary Neutrality: The proposition that changes in the money supply affect nominal variables but do not affect real variables. In the long run, doubling the money supply doubles prices and dollar wages but leaves real production and employment unchanged.

Velocity and the Quantity Equation

• Velocity of Money: The speed at which a typical dollar bill travels around the economy from wallet to wallet.

• The Quantity Equation: $M \times V = P \times Y$     * $M$ = Quantity of money     * $V$ = Velocity of money     * $P$ = Price level     * $Y$ = Quantity of output (Real GDP)

• Implications: A rise in $M$ must be reflected by a rise in $P$, a rise in $Y$, or a fall in $V$. Because velocity is relatively stable and money is neutral (not affecting $Y$), rapid increases in $M$ result in high inflation ($P$ increasing proportionately).

• Example Data Point: If Real GDP = $5,000, Velocity = 5, Money Supply = $2,000, and Price Level = 2:     * $2,000 \times 5 = 2 \times 5,000 = 10,000$.

Hyperinflation and the Inflation Tax

• Causes: Governments print too much money to pay for spending when tax revenue is inadequate and borrowing ability is limited.

• Inflation Tax: The revenue the government raises by printing money. It acts as a tax on everyone who holds money because it erodes the value of the currency.

• The End of Hyperinflation: Ends when the government institutes fiscal reforms, such as cutting spending, to eliminate the need for money creation.

• Historical Examples: Germany and Poland (1921–1925) showed correlated spikes in money supply and price levels.

The Fisher Effect and Costs of Inflation

• Fisher Effect: The one-for-one adjustment of the nominal interest rate to the inflation rate.     * Formula: $\text{Real Interest Rate} = \text{Nominal Interest Rate} - \text{Inflation Rate}$.     * In the long run, money growth increases inflation and the nominal interest rate, while the real interest rate (a real variable) remains unchanged.

• Costs of Inflation:     * Shoeleather Costs: The resources wasted when inflation encourages people to reduce their money holdings (e.g., more frequent trips to the bank).     * Menu Costs: The costs of adjusting prices (e.g., updating price lists).     * Relative-Price Variability: Inflation distorts relative prices, leading to the misallocation of resources.     * Inflation-Induced Tax Distortions: Inflation exaggerates capital gains and treats nominal interest as income, increasing the tax burden and discouraging saving.     * Confusion and Inconvenience: Erosion of the unit of account makes it difficult to compare real values over time.     * Arbitrary Redistribution of Wealth: Unexpected inflation redistributes wealth between debtors and creditors.         * Scenario: Sam Student borrows $20,000 at 7% for 10 years (owing $40,000). Hyperinflation would allow him to pay it off with "pocket change," بينما deflation would make the $40,000 a much greater burden than expected.

Fiscal Policy

• Definition: The use of government spending and taxation to influence the economy and promote growth/reduce poverty.

• Tools:     * Expansionary ("Loose") Policy: Increases aggregate demand through higher government spending or lower taxes.     * Contractionary ("Tight") Policy: Reduces demand via lower spending or higher taxes.

• Components of Expenditure:     * Revenue Expenditure: Day-to-day running costs (salaries, maintenance, interest payments, subsidies). It has short-run effects on GDP.     * Capital Expenditure: Spending on durable assets (highways, dams, infrastructure) that improve the economy's productive capacity.

• Components of Revenue:     * Revenue Receipts:         * Tax Revenue: Direct taxes (progressive, e.g., income, corporate) and Indirect taxes (regressive, e.g., GST, VAT, excise).         * Non-tax Revenue: Interest, dividends from PSUs, fees, fines.     * Capital Receipts: Sale of government assets (privatization) or recovery of loans.

Budget Deficits and Public Debt

• Budget Surplus ($BS$) Formula:     * $BS = TA - (G + TR)$     * $BS = tY - G - TR$ (where $t$ is the proportional income tax rate).

• Deficit Types:     * Revenue Deficit: Revenue expenditure exceeds revenue receipts. Indicates the government is using capital receipts or borrowing for daily expenses.     * Capital Deficit: Capital expenditure exceeds capital receipts.     * Fiscal Deficit: Total expenditure minus government's own receipts. It is the sum of Revenue Deficit and Capital Deficit.

• Public Debt: The accumulated deficit amount over time, including debt and interest owed.

• Financing the Deficit:     * Domestic: Issuing bonds (debt financing), borrowing from domestic money markets (PF, small savings), or borrowing from the RBI (Monetized Debt/money creation).     * External: Bilateral borrowing from other countries, or loans from the IMF, World Bank, or ADB.
