Macroeconomics Flashcards
Categories of Economic Systems
(1) Capitalism
(2) Communism/ Socialism
(3) Mixed economies
Capitalism
AKA Free Enterprise
A system where private parties own most of the means of production and make most economic decisions
Communism/ Socialism
A system where government entities own most of the means of production and make most economic decisions
Mixed Economies
“In between” systems where both private parties and governments own substantial fractions of the means of production and make substantial fractions of the economic decisions
Benchmarks to Measure Economic Activity
(1) GDP
(2) Real GDP
(3) GNP
Gross Domestic Product
“GDP” or “Nominal GDP”
Total dollar amount at current market prices, of all the final goods and services produced within one country’s borders regardless of citizenship or headquarter location of parties involved
Two Ways to Calculate GDP
(1) Income Approach
(2) Expenditure Approach
Income Approach
Sums all income earned in the production of final goods and services, such as wages, interest, rents, business profits, plus adjustments for indirect taxes and economic depreciation
Expenditure Approach
Sums all expenditures to purchase final goods and services by households, businesses, the government, and foreign sectors, minus adjustments for expenditures produced abroad
Real GDP
GDP adjusted for inflation
Total dollar value of all the final goods and services produced expressed using a price level that is constant over time
Most commonly used and most comprehensive measure of economic production
How is Nominal GDP Adjusted to Yield Real GDP
By removing the effects of increases in price from the sum of total purchases of goods
Most commonly used and most comprehensive measure of economic production
Real GDP
Potential GDP
Computed in both nominal and real versions - helps to estimate the degree to which the economy is either underutilizing resources or “overheating”
Who Computes Potential GDP
The Congressional Budget Office
Gross National Product
Total dollar value of all goods and services produced by a country’s residents, including companies headquartered there regardless of whether they were produced within or outside that country’s borders
Inflation
Percentage rate of increase in the price level of goods or services, commonly reported on annual or year-on-year basis
If Inflation is Higher, Money is….
Losing it’s purchasing power
3 Common Measures of Price Inflation
(1) Consumer Price Index (CPI)
(2) Producer Price Index (PPI)
(3) GDP deflator
Consumer Price Index (CPI)
Compares the price of a fixed basket of goods and services a typical urban customer might purchase in an earlier base period and the price of the same basket at later times - used to convert “nominal” figures that are not readily comparable across years into “real” figures that use the same level of prices and are therefore more comparable
Hyperinflation
Similar to inflation except the value of currency is decreased at a much faster rate so prices increase much more rapidly
Deflation
General decline in price level, solution is to increase money supply
Producer Price Index (PPI)
Compares the price of a fixed basket of goods, inputs, and materials purchased by producers at the wholesale level
GDP Deflator
Most comprehensive measure of price levels including prices paid by all parties included in GDP instead of only consumers; Index used to convert nominal GDP into real GDP
Aggregate Demand Curve
Seeks to represent the relationship between:
(1) Total expenditures by consumers, businesses, government, and the foreign sector
AND
(2) The price level at a given point in time
Factors that Cause Aggregate Demand Curve to Slope Downwards
(1) Interest rate effect
(2) Wealth effect
(3) International purchasing power effect
Interest Rate Effect
Higher inflation rates increase nominal interest rates and may decrease consumer borrowing reducing the quantity demanded of items whose purchase is typically financed
Wealth Effect
Higher inflation rated reduced the value of most fixed income investments - having less wealth individuals may consume less
International Purchasing Power Effect
Domestic inflation makes domestic goods and services more expensive in relation to foreign ones, increases quantity demanded of foreign products and decreases quantity demanded for domestic goods and services
Aggregate Supply Curve
Seeks to represent the relationship between:
(1) Total goods and services produced
AND
(2) The price level at a given point of time
* Generally sloping upward
Possible Causes of Inflation
(1) Demand-pull inflation
(2) Cost-push inflation
Demand-Pull Inflation
“The demand curve shifted upward”
When aggregate spending increases, the demand curve moves to the right causing market equilibrium to occur at higher price levels
Excess demand bids up cost of labor and other resources
Causes of Excess Demand in Demand-Pull Inflation
(1) Improved expectations by consumers or businesses
(2) The foreign sector
(3) Government fiscal and monetary policy that turned out to be too loose
Short-Term Phillips Curve
In the short term there is a trade off between inflation and unemployment
Cost-Push Inflation
“The supply curve shifted inward”
If producers/suppliers within one country face increases in the costs of using some inputs the aggregate supply curve would shift to the left causing market equilibrium to occur at a higher price level and at a lower quantity
Since prices of many production inputs are set in international markets, individual countries may experience changes in input costs that are not strictly or directly related to economic conditions in that country
Stagflation
Used to describe periods of high inflation and high unemployment
Multiplier Effect
Increase in final income arising from any new injections
Increase in Output (Multiplier Effect Formula)
Change in spending / Marginal Propensity to Save
Business Cycles
Fluctuations in economic production typically lasting several years
Each business cycle includes one recession/contraction and one expansion
Begins at the peak from the previous expansion and ends at it’s trough
Expansion
Extended period of increased economic production
Recession/Contraction
Brief (typically) periods of decreased economic production
Recession - periods of at least two consecutive quarters of negative growth in real GDP
Depression
Recession that is either particularly deep or long lasting, no formal agreement as to boundary between recession and depression
Recovery
Early stages of an expansion, commonly thought to become a full expansion when the peak from the previous expansion is surpassed
Categories of Indicators Economists Track to Gauge, Evaluate, and Predict Current and Future Economic Conditions
(1) Leading indicators
(2) Coincident Indicators
(3) Lagging indicators
Leading Indicators
Seek to predict whether expansions (or recessions) are likely to end within the next few months
Examples Of Leading Indicators
(1) Stock market prices
(2) Average hours worked per week
(3) New orders for durable goods
(4) Average initial claims for unemployment insurance
(5) Building permits
(6) New private housing starts
Coincident Indicators
Normally move up and down simultaneously with economic expansions and recessions
Examples of Coincident Indicators
(1) Industrial production
(2) Manufacturing and trade sales
Lagging Indicators
Only move up and down months after economic change
Examples of Lagging Indicators
(1) Average prime rate for bank loans
(2) Average duration of unemployment
(3) Unemployment rate
Types of Unemployment
(1) Frictional
(2) Structural
(3) Cyclical
(4) Institutional
Frictional Unemployment
Result of normal turnover of workers between jobs or of new entrants to the workforce; unavoidable will always have some of this type of unemployment even at full employment
Structural Unemployment
Workers who lose their jobs as a result of changes in the demands for goods and services or of technological advances that reduce the need for their current skills
Addressing this type of unemployment generally requires retraining
Underlying problem is speed with which workers may be retrained to meet new demands and technologies
Cyclical Unemployment
Job losses resulting from fluctuations in the business cycle
Key concern during recession; decreases during expansions
Institutional Unemployment
Not recognized by all economists
Affects workers who can’t find employment as a result of government restrictions on the economy
Full Employment
“Natural” or “non-accelerating-inflation” rate of employment “NAIRU”
Rates below which unemployment may not fall sustainably without causing boom conditions that eventually may result in higher rates of inflation
Sum of frictional and structural unemployment (and institutional if recognized)
Interest Rates
Prices that borrowers pay in exchange for funds
Types of Interest Rates
(1) Nominal interest rate
(2) Real interest rate
(3) Risk free interest rate
(4) Federal funds rate (Discount rate)
(5) Prime Rate
Nominal Interest Rates
Those normally quoted by financial institutions
Real Interest Rates
Interest rates adjusted for inflation
Risk Free Interest Rates
Those that would be charged to borrowers if lenders had an absolute certainty of being repaid
Federal Funds Rate (Discount Rate)
Rates that commercial banks charge and pay one another for short-term loans of reserves at the Fed
Prime Rate
Rate banks charge their most creditworthy business customers on short-term loans
Types of Government Involvement in the Economy
(1) Fiscal policy
(2) Monetary policy
(3) Regulatory policy
Fiscal Policy
Involves government setting, applying, and changing levels of taxes, subsidies, and government spending
Expansionary Fiscal Policy
Uses deficit spending to increase aggregate demand and thus output
Appropriate Conditions for Using Expansionary Fiscal Policy
(1) Economic production is below potential
(2) Financial sector failing to lend funds adequately
(3) Unemployment rates are too high
