How does a change in interest rates affect

18
Why do bond prices fall as interest rates rise?
Bond sellers have to offer higher returns (lower price) to attract potential bond buyers, or else they will go elsewhere to get higher interest returns
![Page 19: 1 Chapter 20 Monetary Policy ©2004 Thomson/South-Western Key Concepts Key Concepts Summary Summary Practice Quiz.](https://reader036.fdocuments.net/reader036/viewer/2022070414/5697c0061a28abf838cc569d/html5/thumbnails/19.jpg)
19
Why do bond prices rise as interest rates fall?
Bond sellers are put in a better bargaining position as interest rates fall (higher price); potential buyers cannot go elsewhere to get higher interest returns so easily
![Page 20: 1 Chapter 20 Monetary Policy ©2004 Thomson/South-Western Key Concepts Key Concepts Summary Summary Practice Quiz.](https://reader036.fdocuments.net/reader036/viewer/2022070414/5697c0061a28abf838cc569d/html5/thumbnails/20.jpg)

47

The demand for money in the Keynesian view consists of three reasons why people hold money: (1) Transactions demand is money held to pay for everyday predictable expenses. (2) Precautionary demand is money held to pay unpredictable expenses. (3) Speculative demand is money held to take advantage of price changes in nonmoney assets.

The demand for money curve shows the quantity of money people wish to hold at various rates of interest. As the interest rate rises, the quantity of money demanded is less than when the interest rate is lower.

The equilibrium interest rate is determined in the money market by the intersection of the demand for money and the supply of money curves. The money supply (M1), which is determined by the Fed, is represented by a vertical line.

An excess quantity of money demanded causes households and businesses to increase their money balances by selling bonds. This causes the price of bonds to fall, thus driving up the interest rate.

An excess quantity of money supplied causes households and businesses to reduce their money balances by purchasing bonds. The effect is to cause the price of bonds to rise, and, thereby, the rate of interest falls.

The Keynesian view of the monetary policy transmission mechanism operates as follows: First, the Fed uses its policy tools to change the money supply. Second, changes in the money supply change the equilibrium interest rate, which affects investment spending. Finally, a change in investment changes aggregate demand and determines the level of prices, real GDP, and employment.

Monetarism is the simpler view that changes in monetary policy directly change aggregate demand and thereby prices, real GDP, and employment. Thus, monetarists focus on the money supply, rather than on the rate of interest.

72
The equation of exchange is an accounting identity that is the foundation of monetarism. The equation (MV = PQ) states that the money supply multiplied by the velocity of money is equal to the price level multiplied by real output.
![Page 73: 1 Chapter 20 Monetary Policy ©2004 Thomson/South-Western Key Concepts Key Concepts Summary Summary Practice Quiz.](https://reader036.fdocuments.net/reader036/viewer/2022070414/5697c0061a28abf838cc569d/html5/thumbnails/73.jpg)
73
The velocity of money is the number of times each dollar is spent during a year. Keynesians view velocity as volatile but monetarists disagree.
![Page 74: 1 Chapter 20 Monetary Policy ©2004 Thomson/South-Western Key Concepts Key Concepts Summary Summary Practice Quiz.](https://reader036.fdocuments.net/reader036/viewer/2022070414/5697c0061a28abf838cc569d/html5/thumbnails/74.jpg)
74
The quantity theory of money is a monetarist argument that the velocity of money (V) and the output (Q) variables in the equation of exchange are relatively constant. Given this assumption, changes in the money supply yield proportionate changes in the price level.

75
The monetarist solution to an inept Fed tinkering with the money supply and causing inflation or recession would be to have the Fed simply pick a rate of growth in the money supply that is consistent with real GDP growth and stick to it.
![Page 76: 1 Chapter 20 Monetary Policy ©2004 Thomson/South-Western Key Concepts Key Concepts Summary Summary Practice Quiz.](https://reader036.fdocuments.net/reader036/viewer/2022070414/5697c0061a28abf838cc569d/html5/thumbnails/76.jpg)

Monetarists’ and Keynesians’ views on fiscal policy are also different. Keynesians believe the aggregate supply curve is relatively flat, and monetarists view it as relatively vertical. Because the crowding out effect is large, monetarists assert that fiscal policy is ineffective. Keynesians argue that crowding out is small and that fiscal policy is effective.
