6. 5 What is a Double Coincidence of wants? A situation in which two traders both have what the other person wants © ©1999 South-Western College Publishing

7. 6 Inefficiency of Barter  Time consuming due to the need for the double coincidence of wants

8. 7 What is Money?  Any commonly accepted good that acts as a:  medium of exchange  a measure of value (unit of account)  a store of value

9. 8 What is commodity money?  Actual products that became acceptable as money, thus had 2 purposes to it: to be used as a product or as money

28. 27 Monetary Theory How does monetary policy affect the economy? Differing views on this

29. 28 Begin with the old quantity theory of money, based on the equation of exchange

30. 29 How does the Money Supply effect prices? The Equation of Exchange relates the economy’s price level, the quantity of goods, and the money supply © ©1999 South-Western College Publishing

31. 30 © ©1999 South-Western College Publishing What is the Equation of Exchange? MV = PQ Prices Money QuantityVelocity

32. 31 Note that Q = real GDP, PQ equals nominal GDP

33. 32 What is Velocity? The average number of times per year each dollar is used to transact an exchange © ©1999 South-Western College Publishing

34. 33 Example, suppose PQ, nominal GDP = 8 trillion If the money supply equals 1 trillion, what is velocity? Answer: 8

35. 34 Classical economists believe that the velocity and quantity of output are constant in short-run equilibrium © ©1999 South-Western College Publishing What is the Classical View of Money?

36. 35 Conclusion of the old quantity theory If V and Q treated as constants, then M affects only P-price level is proportional to the money supply

37. 36 36 © ©1999 South-Western College Publishing MV = PQ Prices MoneyQuantity Velocity If V is constant, and if Q is not affected by M, then M can only affect P--this is the conclusion of old classical theory

38. 37 What does the Quantity Theory of Money illustrate? Money does not influence how much we produce but it does influence prices © ©1999 South-Western College Publishing

39. 38 Monetarism, a modern version of the classical quantity theory  Monetarists, V not constant, but stable or predictable  Q tends in the long run to move to its full employment level  Monetarists tend to be critical of allowing the money supply to be too volatile

40. 39 Milton Friedman, best known monetarist Argues that bad monetary policy worsened the great depression Calls for a monetary rule on the part of the Fed, constant growth in the money supply regardless of what is going on in the economy

41. 40 What is the Keynsian View of Money? They reject the idea that V is constant and that Q always reflects full- employment GDP © ©1999 South-Western College Publishing

42. 41 How do the Keynsians view Velocity? Even though they agree that spending and saving are basically stable, velocity is also effected by interest rates and expectations

43. 42 What factors can lead to a rise in velocity? Increased use of electronic banking Use of credit cards Getting paid more frequently Higher rates of inflation Higher interest rates

44. 43 Must look at the demand for money Why hold money instead of other assets?

45. 44 According to the Classical Economist, why do people demand money? People demand money to make transactions © ©1999 South-Western College Publishing

46. 45 What is the Transactions Demand for Money? The quantity of money demanded by households and businesses to transact their buying and selling of goods and services © ©1999 South-Western College Publishing

47. 46 According to the Keynsians, why do people demand money? Transactions motive Precautionary motive Speculative motive © ©1999 South-Western College Publishing

48. Speculative Motive Individuals may choose to hold bonds over money: Because the market value of interest-bearing bonds is inversely related to the interest rate, investors may wish to hold bonds when the interest rates are high with the hope of selling them when interest rates fall.

49. 48 Due to speculative motive, money demand varies inversely with interest rates

51. 50 Now put in a money supply curve, have equilibrium

52. 51 S1 i1i1 Money supply and demand M1M1 D 5151

53. 52 According to the Keynsians, how does money affect GDP? © ©1999 South-Western College Publishing An increase in the money supply increases GDP and not necessarily prices, especially in a recession

54. 53 The Keynesian Transmission Mechanism Increased money supply reduces interest rates, raising planned investment, and thus a multiplier expansion of GDP
