Macroeconomics
|
|
The act of combining many individual markets into one overall market.
|
Aggregation
|
|
Shows the quantity of the domestic product (Y) that is demanded at each given price level (P).
|
Aggregate demand curve (AD)
|
|
Shows the quantity of domestic product(Y) that is supplied at each given price level (P).
|
Aggregate supply curve (AS)
|
|
A price index that represents the average price of goods and services produced in an economy.
|
Price level (P)
|
|
The sum of money values of all final goods and services produced in the domestic economy and sold on organized markets in a year.
|
Gross Domestic Product (GDP)
|
|
Purchased by their ultimate users.

|
|
Only ____________________ is included in GDP.
|
Market activity
|
|
Calculated by valuing all outputs at current prices.
|
Nominal GDP
|
|
Calculated by valuing outputs of different years at a chosen base year's prices. Corrected for inflation.
|
Real GDP
|
|
Refers to a sustained increase in the general price level.
|
Inflation
|
|
Refers to the rate at which the prices increase.
|
Inflation Rate
|
|
Refers to a sustained decrease in the general price level.
|
Deflation
|
|
A period of time during which the total output of the economy declines.
|
Recession
|
|
A government policy designed to prevent or shorten recessions and to tame inflation (to stablize prices).
|
Stabilization Policy
|
|
To improve long-run economic growth, while keeping both unemployment and inflation low.
|
Goal of macroeconomics
|
|
the real GDP that the economy would produce if its resources were fully utilized (in normal times).
|
Potential GDP (Y)
|
|
The growth of the labor force, capital stock, and technical progress.
|
Supply-side factors.
|
|
Actual GDP tends to fluctuate around potential GDP.
|
Short-Run
|
|
Actual GDP tends to converge to potential GDP.
|
Long-run
|
|
Measures the size of the expansion of the economy over time
|
Real GDP Growth
|
|
considers the population effect on a coutry's GDP.
|
Real GDP per capita
|
|
Real GDP/Population =
|
Real GDP per capita
|
|
Real GDP per hour of work.
|
Labor Productivity
|
|
Real GDP/Hours of work =
|
Labor Productivity
|
|
(# of people employed) + (# of people unemployed but who actively seek work) =
|
Labor force
|
|
a person who gives up looking for work and is therefore no longer counted as unemployed and is not part of the labor force.
|
Discouraged worker
|
|
(# of unemployed/Labor force) x 100 =
|
Unemployment Rate
|
|
(Labor force/Working age population) x 100 =
|
Labor Force participation rate
|
|
Unemployed during a job change or of a new entrant into labor force
|
Frictional unemployment
|
|
Unemployed due to structural changes in an industry.
|
Structural unemployment
|
|
Unemployed due to the business cycle. Rises durinig recessions and falls as prosperity is restored. Due to bad economy
|
Cyclical unemployment
|
|
Real GDP tends to fluctuate around potential GDP over time.
|
Business cycle
|
|
a period of falling real GDP-- for at least two successive quarters.
|
Recession
|
|
a period of rising real GDP.
|
Expansion (boom)
|
|
The unemployment rate is never _______ since frictional and structural unemployment always exist in an economy.
|
zero
|
|
includes frictional and structual employment
|
natural rate of unemployment
|
|
Frictional + Structural =
|
Natural rate of unemployment
|
|
If the cyclical unemployment = 0 then
|
The economy is at potential GDP (full-employment GDP)
|
|
the portion of unemployment attributed to output being below potential. Due to recession and bad employment
|
Cyclical unemployment
|
|
production is not maximized with given resources (production is inside the PPF which is inefficient) when the labor is not fully employed.
|
The economic costs of (cyclical) unemployment
|
|
expresses the cost of a market basket of goods relative to its cost in some base period.
|
Price Index
|
|
{(Cost of Market basket in year t)/(Cost of market basket in base Year)} x 100=
|
CPI in year t
|
|
In the base year, CPI =
|
100
|
|
The process of finding the real value of some monetary magnitude by dividing by some appropriate price index.
|
Deflating
|
|
{(Nominal Monetary Magnitude in Year t)/(Price index in year t)} x 100=
|
Real Value
|
|
To compare the purchasing power of monetary magnitudes across different time periods, by converting current dollars to a common base year dollars.
|
Purpose of Deflating

|
The volume of goods and services that it will buy.
|
Purchasing power
