  5. Chapter 25 • Keynesian Economics

  6. Determining GDP • GDP is determined where the C + I line intersects the 45˚ line. • At that level of output, y*, desired spending equals output.

  7. Chapter 30 • The Dynamics of Inflation and Unemployment

  8. Nominal rate of interest = Real rate of interest + Expected rate of inflation Money Growth, Inflation,and Interest Rates • When the public holds expectations of inflation, real and nominal rates of interest will differ. • In the long run, changes in the money supply do not affect real variables, including the real interest rate. But nominal rates, which depend on the rate of inflation, will be affected by the growth of the money supply.

  9. The Quantity Equation • The equation of exchange, or quantity equation, links the money supply and velocity to nominal GDP: • If velocity is predictable, we can use the quantity equation and the supply of money to predict nominal GDP, or the value of spending, on the right side of the equation.

  10. Chapter 27 • Money, the Banking System and the Fed

  11. The Role of the Federal Reservein the Money Creation Process • Open market purchases: The Fed’s purchase of government bonds, which increases the money supply. • Open market sales: The Fed’s sales of government bonds to the public, which decreases the money supply.

  12. Using Concepts to Illustrate the US Economy in Fall 2002 • Production Possibility Frontier Tool: Illustrate the War on Terrorism • Lecture Eight

  13. Guns or Butter War Front: “Guns” This year Last Year Production Possibility Frontier: Real GDP Govt.: Tax it away or borrow to buy it away Opportunity cost of war in“butter” Home Front: “Butter”

  14. Using Concepts to Illustrate the US Economy in Fall 2002 • Production Possibility Frontier Tool: Illustrate that the Government wants more guns and butter, and spends on both increasing nominal GDP faster then real GDP • Lecture Eight

  15. Guns or Butter War Front: “Guns” Government. Wish Nominal GDP Production Possibility Frontier: Real GDP Govt.: Tax it away or borrow to buy it away Home Front: “Butter”

  16. Is Inflation on the Way? • Measure GDP in current (nominal) $ • But how much of the change from year to year is a change in output and how much is a change in prices? • GDP(nominal) = GDP Deflator x GDP(real)

  19. Using Concepts to Illustrate the US Economy in Fall 2002 • Production Possibility Frontier: Real GDP Could be Getting Ready to Decline-Double Dip Recession?

  40. Using Concepts to Illustrate the US Economy in Fall 2002 • What has been the economic impact of the “War on America”? • Destruction of income (flow) • Destruction of wealth (stock)

  41. The Direct Loss of Income • 3000 fatalities • @ $100,000 per year income • $ 0.3 billion

  42. The Indirect Loss of Income: Potential GDP • Full employment of labor • Full employment of capital

  43. Lab Three: National Income and Product Accounts (NIPA)-Ch. 20 Billions of Current $, Seasonally Adjusted at Annual Rates GDP is Gross Domestic Product

  44. The Indirect Loss of Income: Potential GDP • Full employment of labor • unemployment rate has gone from 4 % to 5% • Say we lost 1 % of national income, 2002II $10377 billion, would be $104 billion • Full employment of capital

  46. How Much of the Loss is Attributable to the Attack • As of August 22, the Survey of Professional Forecasters were still relatively optimistic • Calling for a growth rate in real GDP of 2.4% in 2002QIII • calling for a growth rate in real GDP of 2.6% in 2002 QIV
