PART II: Short Answer, 12 points (each question is worth 3 points).

  1. Suppose the economy experiences a negative cost shock, at a time when the Federal Reserve initiates a contractionary monetary policy. Draw a graph illustrating this situation. In equilibrium, what happens to the price level and aggregate output?

Answer:

  1. The Phillips Curve represents the relationship between the inflation rate and the unemployment rate. In 1974, the price of imports increased substantially and again in 1979. What could you predict on the relationship between the inflation rate and the unemployment rate?

Source: textbook chapter14, 269p-270p,274p

Answer: As a result of import price increases which led to shifts in aggregate supply, the relationship between the inflation rate and the unemployment rate was erratic (no clear trade off).

  1. Using the three panel diagram, explain why the AD curve is downward sloping.

As the price level increases, the interest rate increases, investment decreases, and GDP falls.

  1. During 1999 and 2000, a debate raged over whether the United States was below potential GDP. Then, the Federal Reserve decided to boost the economy. What would you expect? Illustrate using an aggregate supply and aggregate demand diagram.

Answer: figure13.5 A shift of the Aggregate Demand Curve When the Economy is on the Nearly Flat part of the AS curve

Part III Read the following article and answer the questions below

Inflation is on the way, with or without growth

1 November 2009 - Issue : 858

Coming out of this dreadful recession may become equally as difficult as being deep in it. The question here is to choose an economic and monetary policy mix to fight on two fronts. For one thing, policies should make sure that the economies will not return to a deeper recession, and, secondly, this policy mix must secure a low inflation growth path.
Is it possible to have both? Let’s see to this. On the face of it, those two goals seem to be the same but they are not. Inflation usually accompanies any growth period, but western economies found some 10 years ago that this is not always a must. Growth can evolve without inflation pressures and in this way it can last longer that in the past, when the fight to control inflation killed growth as well. Now all the major western central banks have set inflation “targets” and whenever consumer price changes exceed those targets, they take measures. This is exactly where we are at the present conjuncture.

1. (2 points) The article says that “the policy mix should make sure that the economies will not return to a deeper recession” and also that “this policy mix should insure a low inflation growth path”. What policy might achieve this? Illustrate using Aggregate Demand and Aggregate Supply curves.

The desired increase in output together with low inflation can be achieved by anything that would shift the AS curve outward to the right. Examples would be anything that would decrease costs such as removal of energy taxes, lowering of payroll taxes, investments that would improve technologies or productivities, etc.

2. (2 points) The article says that policies to promote growth usually promote inflation. What policies to increase growth would result in this outcome? Illustrate using AD and AS diagram.

Any policy that shifted the AD curve to the right (expansionary fiscal or monetary policy) would result in both price increases and increased output.

3. (4 points) The article refers to inflation targeting. Describe what is meant by “inflation targeting”. In contrast, suppose the authorities adopted a policy of “deficit targeting”. Describe what is meant by this.

See chapter 15 of the text for the answer to this question. 2 points are given for a correct description of inflation targeting and 2 points for a correct description of deficit targeting.

-Inflation targeting is when the monetary authorities (e.g. the Federal Reserve) pick a target range for the level of inflation (e.g. 2-4%) and conduct expansionary or contractionary monetary policy to achieve the target level, with contractionary policy happening when the inflation target is exceeded and expansionary policy when inflation is lower than the target range.

-Deficit targeting is when fiscal policy (i.e. taxing and spending voted on by Congress and signed and executed by the President and the Executive Branch) is automatically adjusted to keep the fiscal deficit (G-T) within certain limits. When the target deficit is exceeded then either spending is cut or taxes are raised to achieve the target.
