Components of GDP

Four components of GDP: Consumption (C), Investment (I), Government purchases (G), and Net exports (NX).
GDP formula: Y (GDP) = C + I + G + NX.

Consumption

Refers to household spending on goods and services.
A major driving force behind economic activity and growth.

Investment

Involves spending on capital equipment, inventories, and structures.
Includes household purchases of housing.
Critical for long-term economic expansion and productivity.

Government Purchases

Expenditures by local or national governments on goods and services.
Excludes transfer payments like social security.
Influential in stimulating economic activity through public projects and services.

Net Exports

Represents purchases of domestically produced goods and services by foreign entities.
Calculated as exports minus imports.
Reflects the international trade balance affecting domestic output.

Real GDP

Measures output of goods and services in the economy without adjusting for price changes.
Utilizes fixed prices from a base year for calculations.
Allows for analysis of economic growth that is not distorted by inflation.

Nominal GDP

Measures production of goods and services at current market prices.
Does not account for inflation or changes in price levels over time.

Calculation of Real GDP

Based on a chosen base year to determine fixed prices.
Subsequent outputs are multiplied by the base year prices to calculate real GDP.
Example: If the base year is 2009 with a sausage price of £2.50, that price is used for future output calculations.

Importance of Real GDP

Provides insights into actual changes in domestic production and output.
Reflects consumer satisfaction more accurately than nominal GDP, which includes price level changes.

GDP Deflator

A key measure of the price level, calculated as the ratio of nominal GDP to real GDP, multiplied by 100.
Indicates how price levels have changed compared to a base year.

Calculation of the GDP Deflator

Formula: GDP Deflator = (Nominal GDP / Real GDP) x 100.
A higher deflator suggests significant price level increases.

Interpretation of GDP Deflator Changes

Indicates the overall price level in the economy relative to a base year.
Example: A rise from 100 to 171 in the GDP deflator signifies a 71% increase in price levels over the year.
