Core Formulas

GDP

$$GDP = C + I + G + (X - M)$$

C = Consumption
I = Investment
G = Government spending
X = Exports
M = Imports

Elasticity

$$E_d = \frac{% \Delta Q_d}{% \Delta P}$$

| Elasticity | |E_d| | Description | |------------|------|-------------| | Elastic | > 1 | Sensitive to price | | Inelastic | < 1 | Insensitive to price | | Unit elastic | = 1 | Proportional change |

Inflation Rate

$$\text{Inflation} = \frac{CPI_{new} - CPI_{old}}{CPI_{old}} \times 100%$$

Unemployment Rate

$$\text{Unemployment} = \frac{\text{Unemployed}}{\text{Labor Force}} \times 100%$$

Market Structures

Structure	Firms	Product	Entry	Price Control
Perfect Competition	Many	Identical	Free	None
Monopolistic Competition	Many	Differentiated	Free	Some
Oligopoly	Few	Similar	Barriers	Significant
Monopoly	One	Unique	Blocked	Full

Fiscal vs Monetary Policy

Aspect	Fiscal Policy	Monetary Policy
Authority	Government	Central Bank
Tools	Taxes, Spending	Interest rates, Money supply
Expansionary	↓ Taxes, ↑ Spending	↓ Interest rates
Contractionary	↑ Taxes, ↓ Spending	↑ Interest rates

Key Economic Indicators

Indicator	Measures	Good Sign
GDP Growth	Economic output	2-3% annually
Inflation	Price changes	2% target
Unemployment	Joblessness	< 5%
Interest Rate	Cost of borrowing	Stable

Trade Concepts

Comparative Advantage

Country produces good with lower opportunity cost
Basis for trade even if one country is better at everything

Exchange Rates

Appreciation: Currency strengthens (imports cheaper, exports expensive)
Depreciation: Currency weakens (imports expensive, exports cheaper)
