Purpose of macroeconomics
1.) Measure the health of the whole economy
2.) Guide government policies to fix problems
3 major economic goals
1.) Promote economic growth
2.) Limit unemployment
3.) Keep prices stable (limit inflation)
GDP
Dollar value of all final goods and services produced within a country’s borders in one year.
Purpose of GDP
Compare to previous years (growth)
Compare policy changes (new policy efficiency)
Compare to other countries (competition)
Formula for: % change in GDP
(year 2 - year 1) / year 1 × 100
Not included in GDP
Intermediate goods
Nonproduction transactions
Nonmarket activities (illegal)
How to calculate GDP
1.) Expenditure approach - adds up all spending on final goods
2.) Income approach - adds up all income on selling final goods
Components of GDP
Consumption (household/consumer spending)
Investment (business spending)
Government purchases (gov. spending)
Net exports (exports - imports)
Transfer payment
Payment not made in exchange for goods and services.
Issue with GDP
Doesn’t account for inflation, GDP can be rising with the country being worse off. (Prices raising with inflation)
Nominal GDP
Measured in current prices, doesn’t account for inflation year to year.
Real GDP
Constant or unchanging dollars, adjusts for inflation, best measure of economic growth.
(nominal GDP/GDP deflator) x 100
GDP Deflator
Measure of the price level ratio of Nominal GDP:Real GDP. Shows the rise in prices rather than a rise in quantities produced.
(nominal GDP/real GDP) x 100
Reasons for fluctuation of the economy
Retailer and producers send misleading info. about consumer demand
Advances in technology, productivity, or resources
Outside influences (wars, supply shocks, panic)
Characteristics of economic expansion
1.) Less unemployment
2.) Increase in Real GDP
3.) Rapid job growth
4.) Increasing interest rates
5.) Increasing prices
6.) Fewer social problems
Characteristics of economic recession
1.) Increasing unemployment
2.) Decrease in Real GDP
3.) Reduced job growth
4.) Lower interest rates
5.) Decreasing prices
6.) More social problems
Economic growth defined
Increase in real GDP over time, along with an increase in real GDP per capita over time.
What does economic growth provide to society?
Better goods and services
Increased wages and standard of living
Allows more leisure time
Economy can better meet the wants of society
Business cycles connection to PPC
Can show on both:
Full employment
Unemployment
Inflation
Shifters of PPC that affect GDP
Changes in quantity/quality of resources
Changes in technology
Changes in trade
Unemployment rate
Percent of people in the labor force who want a job but are not working.
Labor force
People who are willing and able to work. Includes employed and unemployed.
3 forms of unemployment
1.) Frictional Unemployment
2.) Structural Unemployment
3.) Cyclical Unemployment
Frictional Unemployment
Individuals who are qualified workers with transferable skills but are not currently working.
Ex: High school/College graduates, people who were fired and are looking for a better job
Seasonal unemployment
Type of frictional unemployment due to time of year and type of job.
Structural Unemployment
Changes in the structure of the labor force making some skills obsolete. Workers do not have transferable skills and jobs will not come back. Permanent loss of jobs is “creative destruction”.
Ex: VCR repairmen, carriage makers
Technological unemployment
Type of structural unemployment where automation and machinery replace workers causing unemployment.
Cyclical unemployment
Results from economic downturns. As demand for goods and services falls, demand for labor falls and workers are laid off.
Natural rate of unemployment
Consists of frictional and structural unemployment because they are unavoidable. Should be 4-6% unemployment. Country is at full rate of employment if there is only the NRU.
Okun’s law
When unemployment is 1% above the natural rate, GDP will falls by about 2%
Issues with the unemployment rate
Can misdiagnose actual unemployment rate due to:
Discouraged job seekers
Part-time workers
Race/age inequalities
Illegal labor
Inflation
Rising general level of prices
Reduces purchasing power of money
Each dollar of income will buy fewer goods than before
Measure of inflation
Government tracks the prices of the same goods and services each year
“Market Basket” is made up of ~300 commonly purchased goods
Inflation rate % change in prices in 1 year
Those hurt by inflation
Lenders: people who lend money at fixed rates
People with fixed incomes
Savers
Those helped by inflation
Borrowers: people who borrow money at fixed rates
Businesses where the price of the product increases faster than the price of resources
Cost-of-living-adjustment
Negotiated wages that rise with inflation.
Consumer price index (CPI)
Most commonly used measurement of inflation for consumers.
price of market basket / price of market basket in base year x 100
Issues with CPI
1.) Substitution bias
2.) New products (newest consumer prices not included by market basket)
3.) Product quality (ignores improvements and declines)
Substitution bias
As prices increase for the fixed market basket, consumers buy less of these products and more substitutes that may not be part of the market basket.
CPI vs. GDP deflator
CPI - Measures prices of only consumption
GDP deflator - Measures everything (government, investment, consumption, and exports)
