• Expansionary Fiscal Policy: Used to stimulate economic growth during periods of recession or slow growth. Involves increasing government spending and/or decreasing taxes.

• Contractionary (Restrictive) Fiscal Policy: Used to slow down economic growth during periods of inflation. Involves decreasing government spending and/or increasing taxes.

Tools of Fiscal Policy

• Government Spending: Direct expenditures on goods and services, infrastructure, defense, etc.

• Taxation: Adjusting tax rates and tax policies to influence disposable income and aggregate demand.

Application of Tools

• Expansionary: Increase spending, decrease taxes.

• Contractionary: Decrease spending, increase taxes.

Monetary Policy

Definition and Implementation

Monetary policy involves managing the money supply and interest rates to influence economic activity. It is implemented by a country's central bank (e.g., the Federal Reserve in the U.S.).

• Expansionary Monetary Policy: Used to stimulate the economy by increasing the money supply and lowering interest rates.

• Contractionary (Restrictive) Monetary Policy: Used to reduce inflation by decreasing the money supply and raising interest rates.

Tools of Monetary Policy

• Open Market Operations: Buying and selling government securities to influence the money supply.

• Discount Rate: The interest rate charged to commercial banks for borrowing funds from the central bank.

• Reserve Requirements: The fraction of deposits banks must hold in reserve.

Application of Tools

• Expansionary: Buy securities, lower discount rate, lower reserve requirements.

• Contractionary: Sell securities, raise discount rate, raise reserve requirements.

Business Cycle

Definition and Phases

The business cycle describes the fluctuations in economic activity over time, typically measured by changes in real GDP.

• Expansion: Rising economic activity, increasing consumption and investment.

• Peak: Highest point of economic activity before a downturn.

• Contraction (Recession): Declining economic activity, decreasing consumption and investment.

• Trough: Lowest point of economic activity before recovery begins.

Graph of Business Cycle

• The business cycle is typically illustrated as a wave-like graph showing real GDP over time, with alternating periods of expansion and contraction.

Consumption and Investment in Each Phase

• Expansion: Both consumption and investment increase.

• Peak: Consumption and investment are at their highest.

• Contraction: Both consumption and investment decrease.

• Trough: Consumption and investment are at their lowest.

Boom versus Bust

Definitions

• Boom: Period of rapid economic growth and high employment.

• Bust: Period of economic decline, often marked by recession and rising unemployment.

Crowding Out

Definition and Effects

Crowding out occurs when increased government spending leads to higher interest rates, which reduces private investment.

• Example: If the government borrows heavily to finance spending, it may drive up interest rates, making it more expensive for businesses to borrow and invest.

Animal Spirits and Sentiment

Definitions

• Animal Spirits: A term coined by John Maynard Keynes to describe the emotional factors that influence economic decision-making, such as confidence, optimism, or fear.

• Sentiment: Refers to the overall mood or attitude of consumers and investors, which can affect spending and investment decisions.

Multiplier

Definition and Formula

The multiplier effect describes how an initial change in spending leads to a greater overall change in national income.

• Formula:

• Where MPC is the marginal propensity to consume.

• Example: If MPC = 0.8, then Multiplier = .

Federal Funds Market Graph

Purpose and Explanation

The federal funds market is where banks lend reserves to each other overnight. The federal funds rate is the interest rate at which these transactions occur.

• The graph typically shows the supply and demand for reserves, with the equilibrium determining the federal funds rate.

• The Federal Reserve can influence this rate through open market operations.
