Study Notes

Macroeconomics Objectives

Sustainable rates of growth
Low level of unemployment
Low level of inflation
Equitable distribution of income

Macroeconomics

Branch of economics focusing on the entire economy, not individual markets.
Analyzes large-scale economic phenomena and aggregates.

Gross Domestic Product (GDP)

Total value of goods and services produced in a country.

Unemployment Rates

Percentage of people actively seeking employment but unable to find it.

Inflation & Deflation

Prices of goods rising or falling.

Government Policies

Fiscal policy: Government spending and taxation.
Monetary policy: Controlling the money supply and interest rates.

Economic Growth

Increase in a country's productive capacity.

Trade & Balance of Payments

Flow of goods, services, and capital across borders.

Key Goals

Economic stability (minimizing recessions and controlling inflation)
Full employment
Economic growth (nation's income and living standards)
International trade equilibrium (balanced interactions)

Industrial Level

Rationale for almost all business activities
Good economic indicators encourage investment and expansion.
Ominous indicators encourage stability or even retrenchment.
Companies are aware of the link between the economic environment and their profitability.
Risk sensitivity to macro events (e.g., oil prices, exchange rates)

Circular Flow of Income

Money flows directly between households and firms.
Money is a stock concept (amount at a given time); income is a flow concept (per time period).
Velocity of circulation is the proportion between money and income.
Aggregate demand (AD): Total spending on goods and services produced within a country over time.
Injections (J): Consumer spending (Cd), Investment (I), Government spending (G), Export expenditure(X).
Withdrawals (W or Leakages): Import expenditure (M), Net taxes (T), Savings (S)

Relationship between Injection and Withdrawal

Direct link between Savings & Investment, Gov expenditure & Tax, Import & Export.
Different decisions for spending and saving.
Imports and exports will also differ.
Budget surplus or deficit.

Measuring National Income (GDP)

Product method, income method, expenditure method
Each transaction equally contributes to the economy's income and expenditure.

Functions of Money

Medium of exchange
Means of storing wealth
Means of evaluating future claims and payments
Means of establishing value.

Attributes of Money

Durability
Divisibility
Transferability
Non-counterfeitability

Narrow and Broad Money

Narrow money (M1): Most liquid forms of money. (Cash and other easily convertible money.)
Broad money (M2, M3): Includes less liquid assets that can be converted to cash with effort (e.g., time deposits, savings, money market funds)

Fiat Money

Modern economic systems
Monetary value derived from government trust
Accepted in exchange
Not connected to any tangible asset.

Eurozone Monetary Aggregates

Different classification of money supply based on their liquidity.
Liquidity: How easily an asset can be converted to cash.
M1, M2, M3 are monetary aggregates that are used in the ECB (European Central Bank) to calculate the size of the money supply.

Roles of the Central Bank

Note issue
Lender of last resort
Liquidity provider to banks
Oversee financial institutions
Manage government borrowing
Control inflation
Exchange rate policy & reserve management

Bonds

Fixed income instruments representing a loan.
Typically provide a fixed or predictable income stream to investors.
Primary market: Initial bond issue.
Secondary market: Bonds traded by investors post-issue.
Inverse relationship between bond prices and interest rates.

Treasury Bills

Short-term debt securities issued by governments.
Sold at discounted prices and redeemed at face value at maturity.
Inverse relationship between the price of bonds and the interest rate.

Controlling Money Supply: Government Bonds

Government's way of raising money through taxes and bond sales.
Buying bonds increases money supply.
Selling bonds decreases money supply.

Open Market Operations

Selling Treasury bills (TBs) to reduce money supply
Buying Treasury bills (TBs) to increase money supply

Bank Credit Creation

Banks expand deposits through lending.
Increase in deposits increase money supply.
Banks create money through lending to people—who deposit it back into the bank.

Money Multiplier

The number of times the initial injection of cash is multiplied in the money supply.
Calculated using the required reserve ratio.

Capital Adequacy Ratio (CAR)

Capital portion of deposits for banks
Ensures bank stability
Amount of capital relative to risk-weighted assets (RWA).

Aggregate Demand (AD)

Total spending on goods and services in an economy.
Downward sloping: as prices rise, people buy less.
Shifts in AD: Consumption, Investment, Government spending and Net Exports (NX).

Factors influencing AD curve

Wealth/income effect (P & C)
Interest rate effect (P & I)
Exchange rate effect (P & NX)

Supply-Side Policies

Policies aimed at increasing the productive potential of an economy.
Reducing barriers, enhancing market flexibility, raising productivity.
Fiscal policies (e.g. tax cuts, government spending).
Policies of deregulating and/or privatizing industries to encourage competition and lower costs.

New Classical Supply-Side Policies

Reduce government expenditure
More efficient use of resources
Reduce the size of the public sector
Crowding out (private sector investment).
