Study Notes
Introduction to Economics
- Microeconomics studies how households and firms make decisions and interact in markets.
- Macroeconomics studies economy-wide phenomena, including inflation, unemployment, and economic growth.
Measuring a Nation's Income
- Gross Domestic Product (GDP) measures the total income of everyone in the economy and the total expenditure on the economy's output of goods and services.
- For a whole economy, income must equal expenditure.
Circular-Flow Diagram
- The circular-flow diagram simplifies the economy, assuming markets for goods and services and factors of production, households (spending all income, buying all goods and services) and firms (paying wages, rent, profit to resource owners).
Measurement of GDP
-
GDP is the market value of all final goods and services produced within a country in a given period of time.
-
Market prices reflect the value of goods.
-
GDP includes all items produced and sold legally in markets, excluding items produced and sold illicitly or made and consumed at home.
-
Includes tangible goods and intangible services.
-
Includes goods and services currently produced.
-
Focuses on domestically produced goods, regardless of the producer's nationality.
-
Measured over a year or quarter.
Components of GDP
-
Identity: Y = C + I + G + NX
- Y = GDP
- C = consumption
- I = investment
- G = government purchases
- NX = net exports
Consumption (C)
- Spending by households on goods and services.
- Includes durable goods (e.g., cars), nondurable goods (e.g., food), and services (e.g., education).
- Excludes purchases of new housing.
Investment (I)
- Purchase of (capital) goods that will be used to produce other goods and services in the future.
- Includes business capital (structures, equipment, intellectual property), residential capital (landlord's apartments, homeowners' residences), and inventory accumulation.
Government Purchases (G)
- Government consumption expenditure and gross investment.
- Spending on goods and services by local, state, and federal governments.
- Does not include transfer payments.
Net Exports (NX)
- Exports – Imports
- Exports: Spending on domestically produced goods by foreigners
- Imports: Spending on foreign goods by domestic residents.
2015 U.S. GDP Data
- U.S. GDP in 2015: almost $18 trillion.
- GDP per person: $55,822.
- Consumption: $38,218 per person (68% of GDP).
- Investment: $9,402 per person.
- Government purchases: $9,919 per person.
- Net exports: -$1,657 per person (Americans spent more on foreign goods than foreigners spent on American goods).
Real vs. Nominal GDP
-
Nominal GDP measures production of goods and services at current prices.
-
Real GDP measures production of goods and services at constant prices (a base year is chosen).
-
Real GDP is not affected by changes in prices, while nominal GDP is.
-
For the base year, Nominal GDP = Real GDP.
-
GDP Deflator = (Nominal GDP / Real GDP) * 100. It measures the current level of prices relative to the base year. It can be used to take inflation out of nominal GDP.
Inflation
- Inflation is a rise in the economy's overall price level.
- Inflation Rate = [(GDP Deflator in Year 2 - GDP Deflator in Year 1)/GDP Deflator in Year 1] * 100
A Half Century of Real GDP
- Real GDP grows over time.
- The real GDP of the U.S. economy in 2015 was more than four times its 1965 level.
- Average growth has been about 3% since 1965, though not steady, with interruptions from recessions.
Recession
- A recession is a period of two consecutive quarters of falling real GDP.
- Recessions are marked by lower incomes, rising unemployment, falling profits, and increased bankruptcies.
GDP and Quality of Life
- Although GDP is a measure of economic well-being, it does not perfectly capture quality of life.
- GDP doesn't include leisure, the value of activities outside markets, or the quality of the environment.
- It also doesn't account for income distribution.
- Rich countries tend to have higher GDP per person and better life expectancy, literacy, and internet usage than poor countries. However, poor countries may have other challenges.
