Chapter 9 the is-lm/ad-as model: a general framework for macroeconomic analysis. 9. 1 multiple-choice questions: the fe line shows the level of output at which the ________ market is in equilibrium, goods, asset, labour, money. Diff: 1 type: mc page ref: 305: the fe line is vertical because the level of output at full employment doesn"t depend on the, real wage rate, level of employment, marginal product of labour, real interest rate. Copyright 2012 pearson canada inc: a temporary increase in government purchases causes the real interest rate to ________ and output to ________, rise; rise, rise; fall, fall; rise, rise; remain unchanged. Diff: 2 type: mc page ref: 310: a rise in expected future output that doesn"t affect labour supply would shift the is curve. ________ and the fe line ________: down; is unchanged, down; right, up; is unchanged, up; right.

a. fall and SRAS to shift to the left until long-run equilibrium is achieved.

b. fall and SRAS to shift to the right until long-run equilibrium is achieved.

c. rise and SRAS to shift to the left until long-run equilibrium is achieved.

d. rise and SRAS to shift to the right until long-run equilibrium is achieved.

2) In a self-regulating economy, inflationary gaps are automatically eliminated in the long run by:

a. decreases in wage rates that cause short-run aggregate supply to shift rightward.

b. decreases in wage rates that cause short-run aggregate supply to shift leftward.

c. increases in wage rates that cause short-run aggregate supply to shift rightward.

d. increases in wage rates that cause short-run aggregate supply to shift leftward.

3) Assume the economy is initially in equilibrium at the full-employment level of real GDP. If businesses and consumers become pessimistic regarding future economic conditions, ceteris paribus, the aggregate demand curve will shift to the ________, causing the level of output to ______.

a. left; fall

b. right; fall

c. left; rise

d. right; rise

4) Economists that advocate a macroeconomic policy of laissez-faire:

a. believe the economy is self-regulating only if the government intervenes to move the economy to equilibrium at natural real GDP.

b. believe the economy is self-regulating and will automatically move to equilibrium at natural real GDP in the long run.

c. also advocate central planning and government control of resources.

d. also advocate active government intervention in the economy.

5) Which of the following summarizes the process for closing a recessionary gap if the economy is self-regulating?

a. Labor shortages put upward pressure on wages, which leads to higher costs of production and a decrease in short-run aggregate supply.

b. Labor shortages put downward pressure on wages, which leads to increases in employment and spending and an increase in aggregate demand.

c. Unemployed resources put upward pressure on the price level, which leads to higher wages, increases in spending, and increases in aggregate demand.

d. Unemployed resources put downward pressure on the price level, which leads to lower costs of production and an increase in short-run aggregate supply.

Consider the scenario in which the Fed is implementing a contractionary monetary policy aimed at alleviating inflationary pressures.In this regard please provide an answer to the questions listed below. In order to answer, it might be a good idea to use a money market diagram and show how interest rates affect the economy using the AD/AS diagram. No need to submit the graphs, but once again drawing the two graphs (money market and AD/AS) for yourself will go a long way in guiding you towards the right answer. Note. In the static AD/AS model, initially assume that the economy is in SR equilibrium and real GDP is above potential GDP. a) As a result of the contractionary monetary policy pursued by the Fed, what would happen with the interest rate? The interest rate is going to (rise/fall/stay fixed) Blank 1 . b) What would happen with the short run aggregate supply curve? Short run aggregate supply curve will shift (left/right/stay fixed) Blank 2 . c) What would happen with the long run aggregate supply curve? Long run aggregate supply curve will shift (left/right/stay fixed) Blank 3 . d) What would happen with the aggregate demand curve? Aggregate demand curve will shift (left/right/stay fixed) Blank 4 . e) What would happen with the Real GDP level? Real GDP will (rise/fall/stay fixed) Blank 5 . f) What would happen with the employment level? Unmployment level will (rise/fall/stay fixed) Blank 6 .
