Study Notes

Monetary Theory and Economic Impact

Monetary Theory: Studies the effects of monetary policy and money supply on the economy.
Understanding money supply is crucial as it influences the overall quantity of money in the economy.

Key Questions and Concepts

Major question in monetary theory: Do interest rates significantly affect money demand?
Quantity Theory of Money: Developed by classical economists; explains the relationship between money supply and nominal income, asserting that interest rates have no impact on money demand.

Irving Fisher's Contributions

Irving Fisher: Key figure in classical economics; established the connection between money supply (M) and total spending on goods/services (P*Y).
P*Y signifies aggregate nominal income, equating to nominal GDP.

Velocity of Money

Velocity of Money: Indicates how frequently money is used in transactions within an economy.
Equation for velocity: ( v = \frac{P \times Y}{M} ).

Equation of Exchange

Equation of Exchange: ( M \times V = P \times Y ) illustrates the relationship between money supply, velocity, and nominal income.
Highlights that changes in money supply do not directly equate to changes in nominal income.

Demand for Money

Demand for Money: Refers to the amount of money individuals wish to hold.
Fisher's demand for money equation: ( M^d = k \times P \times Y ) where ( k ) is constant, suggesting demand is driven by income, not interest rates.

Long-Run vs. Short-Run

Classical economists advocate that price flexibility maintains full employment, stabilizing aggregate output.
The quantity theory implies that inflation rates correlate positively with increases in money supply in the long run.

Inflation and Money Supply Dynamics

The inflation rate is influenced by changes in money supply and aggregate output: ( \pi = % \Delta M - % \Delta Y ).
Historical data reveals a strong connection between money growth rates and inflation rates across various periods and nations.

Government Budget Deficits

Government Budget Deficit: Occurs when spending exceeds revenue.
Governments can finance deficits through taxes, borrowing, or printing money, influencing monetary base and money supply.

Challenges with Monetary Policy

Printing money may not effectively reduce deficits due to governmental restrictions and public trust.
If the public does not hold bonds, the central bank may purchase them, thus increasing the monetary base.

Keynes vs. Classical Theories

John Maynard Keynes: Criticized the quantity theory for assuming constant velocity and minimizing the importance of interest rates on money demand.
Liquidity Preference Theory: Introduced by Keynes, focusing on precautionary, speculative, and transactional motives for holding money.

Payment Technology Advancements

Technological improvements in payment methods impact money demand, shifting from cash to electronic transactions.
Keynes argued that technology decreases the need for holding money relative to income.

Precautionary and Speculative Motives

Precautionary Motive: Individuals retain cash for unforeseen emergencies, impacting their overall money holdings.
Speculative Motive: People hold liquid assets as a store of wealth, anticipating changes in interest rates affecting other assets.### Bonds and Money Demand
Increased nominal rates on bonds raise the opportunity cost of holding money, leading to decreased money demand.
Higher interest rates result in a decreased money supply due to reduced spending and increased saving, as the cost of borrowing rises.
Inflation and spending tend to decline, while higher borrowing costs make lending more profitable.
Bond prices drop when interest rates rise, as older bonds with lower rates are less attractive compared to new issues.

Keynes Demand for Money Model

Differentiates between real and nominal qualities, emphasizing that the value of money is based on purchasing power.
An increase in price level reduces the quantity of goods one can buy with the same nominal amount of money.

Real Money Balances

Defined as the quantity of money adjusted for price changes, indicating real purchasing power.

Liquidity Preference Function

Represents demand for real money balances: Md/P = L(i, Y).
The function shows that money demand is inversely related to nominal interest rates and directly related to real income.
A rise in nominal interest rates decreases the demand for real money balances.

Velocity of Money

Velocity is not constant; it fluctuates with changes in interest rates.
The liquidity preference function demonstrates that as nominal interest rates increase, liquidity decreases and velocity increases.

Keynesian vs. Classical Economists

Keynesians reject the notion that nominal income is solely determined by the money supply.
They argue against the classical assumption that velocity remains constant over time.

Portfolio Theory of Money Demand

Explains how individuals choose asset composition in their portfolios, factoring in risk and return.
Demand for a specific asset is influenced by wealth, comparative expected returns, liquidity, and relative risk.

Wealth and Money Demand

An increase in an investor's wealth generally raises the demand for money assets but has a limited effect if income remains constant.

Dominated Assets

Defined as assets that are less desirable compared to others that offer higher returns with similar risk.

Risk of Money as an Asset

While money appears less risky due to universal acceptance, its real returns are affected by inflation, making it volatile.
Investors may seek alternative assets if the real return on money declines.

Inflation Hedges

Investments aimed at preserving purchasing power when inflation occurs, leading to a shift away from cash to less affected assets.

Financial Innovation Impact

New liquid assets (e.g., home equity lines and money market funds) reduce the relative liquidity of traditional money, decreasing its demand.

Factors Influencing Demand for Money

Key determinants of money demand include interest rates, income, payment technology, wealth, risk of alternative assets, inflation risk, and liquidity of other assets.
