Gross Domestic Product (GDP)
Market value of final goods and services newly produced within a nation during a fixed period of time
– Market value– Newly produced final goods and services– Fixed period of time
GDP per capita is an economy’s GDP divided by its population

The Income-Expenditure Identity
Y = C+I+G+NX
– Y = GDP (Income)
– C = consumption
– I = investment
– G = government purchases
– NX = net exports
What is produced is spent somewhere
The Income-Expenditure Identity
Expenditures in 1996 Billions of dollars Percent of GDP
Personal Consumption Expenditures (C) 5151 68.0Gross private domestic investment (I) 1117 14.7Government purchases of goods and services (G) 1406 18.6Net exports (NX) -99 -1.3 Exports 855 11.3 Imports 954 12.6
Total (equals GDP) (Y) 7576 100.0
GDP is same as National Income
GDP = National Income + Indirect taxes +Depreciation - Net Factor Payments (NFP)
The income approach says that what is produced is income to someone
National Income
Income in 1996 Billions of dollars Percent of GDP
Compensation of employees 4449 58.7
Proprietors' income 518 6.8
Rental income of persons 127 1.7
Corporate profits 654 8.6
Net interest 403 5.3
Total (equals National Income) 6151 81.2
National SavingS = Y+NFP-(C+G)
Savings rate is savings as a percent of GDP
Current Account
CA = NX+NFP = S-I
Budget Deficit
Sg = (T-TR-INT)-G
• T = Tax Receipts
• TR = Transfers to private sector
• INT = interest on national debt
• G = Government purchases
• Sg=Budget (surplus if positive, deficit if negative)

Some Fundamental Prices
The General Price Level
Y = nominal GDP
Y = P * y
• P = GDP deflator or simply market price• y = real GDP or quantity of goods produced
The General Price Level
• Price growth = inflation:

Nominal Interest Rate
• The (short-term) interest rate is the risk-free rate of return that can be earned in the market.
• R = Dollar interest rate
• Invest $1 today at the rate R
• Receive $(1+R) in one period (day, week, month, year, etc.).
• The (ex post) real interest rate, r, is the rate of return in units of goods.
r = R -
• (Ex post) real interest rate is nominal interest rate minus (realized) inflation.
Ex Post Real Interest Rate
• The inflation rate is typically not known
• Expected (ex ante) real interest rate = nominal interest rate - expected inflation
re = R - e
• The expected real interest rate is the nominal interest rate less expected inflation – the Fisher equation
