Indictators • Leading • Predict what the economy will do • Coincident • Current status of the economy • Lagging • After the fact, explains what has happened.
GDP • Gross Domestic Product • Final Output. • EG Sale of pen included, but not the manufacture of casing or ink. • Manufactured during current year. • Used cars or second hand clothes excluded. • National Borders.
GDP Continued • National Borders • Includes all production regardless of who produces it. • Toyotas built in U.S. factories. • Excludes items built or financed by Americans outside of the U.S. • Coke Plant in Europe.
How to measure GDP • 3 Ways • 1 - Expenditure Approach • Sum of purchases by final users. • 2 - Income Approach • If final price = all income & costs incurred. • 3 - Value-added Approach • Total sales - value of intermediate goods.
Expenditure Approach to GDP • GDP = C + I + G + ( X - M ) • C = Personal Consumption Expenditures • I = Gross Investment • G = Government Purchases • X = Exports • M = Imports
Expenditure Method Components • C = Consumption • All final products • I = Investments • Capital investments • Inventory investments • G = Government Purchases • Excludes transfer payments • X = Exports • M = Imports • Trade surplus is a positive number • Trade deficit is a negative number
Other Points of Notes • Inflation • Nominal GDP • Not adjusted for inflation. • Real GDP • Adjusted for inflation
Calculating Nominal GDP • Nominal GDP • = Sum of TR (P*Q) of all goods • = (AP2)*(AQ2)+(BP2)*(BQ2) • Nominal Prices * Quantity • Nominal prices are prices from tear of sale. • Calculates size of economy for a period in dollars from that period • EG GDP for 2007 in 2007 dollars.
Calculating Real GDP • Real GDP • = Sum of TR using original prices with current quanity • = (AP1)*(AQ2)+(BP1)*(BQ2) • Real Prices * Quantity • Real prices are prices from original or base year • Calculates size of economy for a period in dollars from a base period • EG GDP for 2007 in 2001 dollars.
Inflation & Deflators • Inflation – Amount that prices rise for the same goods. • Deflator – A measure that adjusts the GDP for inflation. • (Nominal GDP / Real GDP) * 100
Example – BBQ GDP • Hot Dogs Hamburgers • Year Price Amount Price Amount • 2006 $1 100 $2 50 • 2007 $2 150 $3 100 • 2008 $3 200 $4 150
Nominal GDP • Nominal GDP = (P1)*(Q1)+(P2)*(Q2) • Nominal Prices * Quantity • 2006 = 1*100+2*50 = $200 • 2007 = 2*150+3*100 = $600 • 2008 = 3*200+4*150 = $1,200
Real GDP • Real GDP = (PB)*(Q1)+(PB)*(Q2) • Real (base year) prices * quantity • 2006 = 1*100+2*50 = $200 • 2007 = 1*150+2*100 = $350 • 2008 = 1*200+2*150 = $500
GDP Deflator • (Nominal GDP)/(Real GDP)*100 • 2006 = (200/200)*100 = 100 • 2007 = (600/350)*100 = 171 • 2008 = (1,200/500)*100 = 240
Other Points of Note • Limitations • Accuracy of information • Timeliness of information • Non-market activities • Underground economy
