Study Notes

Measuring the Size of the Economy

The national accounts are statistical measures used to quantify the size of the economy, providing a comprehensive picture of economic fluctuations and growth.

Economic Fluctuations & Unemployment

Fluctuations in a nation's total output (GDP) have a significant impact on unemployment, causing hardship for individuals.
Economic shocks can be positive or negative, causing booms or recessions.
Data shows a correlation between higher unemployment rates and increased searches for anti-stress medication, suggesting a direct link between the two.

The GDP Equation

Economists measure the size of the economy using the national accounts, using a circular flow approach.
GDP can be calculated using three perspectives:
- Expenditure: Sum of all spending on final goods and services.
- Income: Total income earned by all factors of production.
- Production: Total value added by all industries.

Key Economic Variables

Exports (X): Goods and services produced domestically and sold internationally.
Imports (M): Goods and services produced internationally and purchased domestically.
Trade Balance (X - M): Difference between exports and imports.
- Trade Deficit: When imports exceed exports.
- Trade Surplus: When exports exceed imports.
Aggregate Demand: Total spending on goods and services in the economy.
- Y = C + I + G + X - M (where Y is GDP, C is consumption, I is investment, G is government spending, X is exports, and M is imports).

Okun's Law

It is an empirical relationship connecting real GDP growth with changes in the unemployment rate.
The relationship is usually negative, implying that positive GDP growth is associated with a decrease in the unemployment rate.
The equation for Okun's law is: Δut = α + β (GDP growtht)
- Δut: Change in unemployment rate at time t.
- (GDP growtht): Real GDP growth at time t.
- β: Okun's coefficient, determining the impact of GDP growth on unemployment.

The Role of Government in the Economy

Government spending on goods and services includes spending on infrastructure, defense, and education.
Government transfers are not included in government spending in the national accounts, and include unemployment benefits and pensions.

Data and Examples

In 2010, the US had a trade deficit of 3.4% of GDP, while China had a trade surplus of 3.6% of GDP.
Estimated Okun's law coefficients:
- US: β = -1.2298
- Germany: β = -0.20
Germany had a GDP decline of 5.1% in 2009, which was predicted to lead to an unemployment increase of 1.58 percentage points by Okun's law.
Total government spending in 2012, including transfers:
- France: 57% of GDP.
- US: 40% of GDP.
