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

1. Define the recognition lag, the implementation lag, and the response lag.

Answer: Recognition lag: time it takes to recognize the existence of a boom or a slump.

Implementation lag: time that it takes to put a desired policy into effect once economists and policy makers recognize that the economy is in a boom or a slump.

Response lag: the time that it takes for the economy to adjust to the new conditions after a new policy is implemented; the lag that occurs because of the operation of the economy itself.

2. Briefly describe and graphically illustrate the Philips curve.

Answer : See the textbook

3. Derive the aggregate demand curve using the three panel graph illustrating the goods market, money market and investment and focusing on the investment linkage between money market and goods market.

Answer:

[pic]

4 . Briefly describe the effects of taxes and transfers on household consumption and labor supply. You can assume that the substitution effect dominates when describing the labor supply decision, and that output prices remain constant.

Answer:

We know from the consumption function that increases (decreases) in taxes have a negative (positive) effect on consumption, and increases (decreases) in transfer payments have a positive (negative) effect on consumption. For the labor supply decision, an increase in taxes decreases the real wage, causing workers to substitute towards leisure. Therefore, the substitution effect causes workers to work less. Decreases in the real wage also decrease real income, causing workers to consume less of everything, including leisure. Therefore, the income effect causes workers to work less. Since the substitution effect dominates, the result from an increase in taxes is a decrease in labor supply. Similar reasoning would show that labor supply increases from a decrease in taxes. When transfers are increased (decreased), there is a pure income effect since wages do not change, and workers consumer more of everything, including leisure. Therefore, increases (decreases) in transfers result in decreases (increases) in labor supply.

Part III. Read the following excerpt from an article from the business section of the New York Times on July 11th, 2008 and answer the following questions. Use graphs where appropriate.

Oil Shocks

The head of the Organization of the Petroleum Exporting Countries warned on Thursday that oil prices would experience an “unlimited” increase in the event of a military conflict involving Iran because the group’s members would be unable to make up the lost production. Skip to next paragraph

“We really cannot replace Iran’s production — it’s not feasible to replace it,” Abdalla Salem el-Badri, the OPEC secretary general, said in an interview.

Iran, the second-largest producing country in OPEC after Saudi Arabia, produces about four million barrels of oil a day out of the daily worldwide production of close to 87 million barrels.

The country has been locked in a long dispute with Western nations over its nuclear ambitions.

In recent weeks, the price of oil has risen higher on speculation that Israel could be preparing an attack on the country’s nuclear facilities. The saber rattling intensified this week with missile tests by Iran.

That has further unnerved oil markets because of concerns that any conflict with Iran could disrupt oil shipments from the gulf. In New York, crude oil climbed $5.60, to $141.65 a barrel. – James K.

1. Using an aggregate supply and demand diagram, explain what effect an attack on Iran would have on the price level and output level in the U.S. economy in the short run.

[pic]

The price level rises and output falls.

2. Suppose that the Federal Reserve wished to keep the price level at pre-conflict levels. Explain using a three-panel diagram and an aggregate supply and demand diagram how the Fed could accomplish this.

[pic]

3. After the Fed engages in the monetary policy prescribed in the last question, what will be the overall effect on the money supply, the money demand, the interest rate, investment, output, the price level, and aggregate demand.

Money supply falls, interest rate rises, investment falls, output falls, the price level falls, aggregate demand falls, money demand falls
