Module Notes: GDP, Inflation, and the Four Markets (Nominal vs Real)

GDP (Gross Domestic Product)

Represents all goods and services produced in an economy.

Inflation

Reflects the overall change in price levels.

GDP Components

Consumption (C), Investment (I), Government spending (G), Net exports (NX = Exports
− Imports).

Factors of Production

Resources like capital, labor, and other inputs that firms demand to produce GDP.

Nominal Terms

Dollar values influenced by current prices and inflation.

Real Terms

Quantities with inflation removed, typically by using base-year prices to reveal true quantities.

Money Market

A market for short-term assets, liquidity, and money holdings.

Loanable Funds Market

A market for longer-term borrowing and lending.

Short-run Interest Rate (i or r)

The opportunity cost of holding money (not spending) versus using money to purchase goods/services.

Money Creation

Primarily occurs through the banking system via fractional reserve banking and monetary policy.

Financial Markets

Markets involving bonds and stocks, which are nominal assets affecting wealth, investment, and saving.

Real GDP

A measure of output that uses base-year prices to value quantities of goods/services, stripping out inflation effects.$Real\ GDP = \sum_j P_j^{base} \cdot Q_j$

Nominal GDP

A measure of output that uses current prices and quantities.$Nominal\ GDP = \sum_j P_j^{t} \cdot Q_j^{t}$

Labor Market

Where individuals sell labor to firms in exchange for compensation; excess supply indicates unemployment.

Circular Flow of Income and Expenditure

Describes the interactions between households, firms, and the government in an economy, illustrating the flow of money, goods, and services.
