Chapter 8/9/10 Econ review
GDP
can be used to measure the economic growth of a country in current dollar value, level of GDP indicates the size of economy and changes determine whether it is contracting or expanding
Income approach vs expenditure
Expenditure: c +g + I+ (x-m)
Income: uses 3 income items in addition to depreciation and taxes
Depreciation
The loss of value that an asset faces overtime
Depreciation = gross investments- net investments
Final and intermediate products
Final: do not need further processing, accounted in GDP
Intermediate: purchased by businesses manufacturing, not accounted in GDP
Nominal GDP
Final value of GDP expressed in current dollar value
N= R x D
Real GDP
final value of GDP expressed in base year value. Discounts inflation, base year is 2002 for GDP calculations
R= N/ D
GDP per capita
GDP is total value of goods and services in a nations border
GDP per capital indicates the changes in trends and a nation's living standards over time, helps resolve misleading GDP
GDP per capita = GDP / population
Exclusions from GDP
GDP involves market value which can overlook other productive activities
1. Non market value activities: volunteering, renovating own home
2.underground economy: smuggling, services paid in cash, activities that are kept off the books
Same GDP, different standards of living, how?
GDP can be understated or overstated based on countries underground activities, population, debt, income distribution
Limitations
EPCILE
Excluded activities, product quality, composition of output, income distribution, leisure, environment
Inflation
Increase in prices for an entire economy
Hyperinflation: price increases are out of control
Inflation rate
Rate = ((CPI current year / CPI previous year)/ CPI previous year ) x100
CPI
Consumer price index, a device used to measure inflation, it surveys the consumer spending habits based on their shopping baskets
CPI = price of basket current/ price of basket base x100
CPI limitations
CCSP
Consumer difference: not always same as urban
Charges in spending patterns
Size of household
Product qualify / New product
Nominal income/ Real
Nominal income: income in current dollar
Real income: income in base year dollar, inflation adjustment
Real income= nominal income / CPI (in hundredths)
Rationale behind using Real GDP
In order to compare economic growth and well being of countries,it has to be done without inflation, which why you use real GDP
Economists also assess the changes in outputs which cannot be assessed with inflation
GDP deflator
Indicator of price changes/ falls for all goods and services, measure of inflation
GDP deflator = nominal/ real X 100
Unemployment rate
Number of unemployed people / number of people in labour force
Employment
# of ppl unemployed = unemployed ppl that are looking for jobs actively (4 weeks)
I of ppl in labour force= employed ppl + ppl looking for work
4 types: FSCS
Frictional
Structural
Cyclical
Seasonal
Natural rate of unemployment
= full employment
= frictional + structural
AD
Aggregate Demand is total demand for a good or service in an economy
Factors: CIGN
consumption
Investments
Government
Net exports
AS
Aggregate supply is the total supply of a good or service in an economy
Factors: IRPG
Input cost prices
Resource supplies
Productivity
Government regulations
Inflationary Gap
Gap between aggregate demand and full employment equilibrium, characterized by high inflation, low unemployment and high, GDP growth
Recessionary gap
Gap between I could get demand and full employment, equilibrium, characterized by low inflation, high unemployment, and low GDP growth
