Question

Consider an economy that abides by a Dynamic AS/AD model as presented in class, which, in period t-1, is in a short equilibrium that happens to coincide with a long run equilibrium. In period t there is a negative supply shock which dissipates in period t+1. There are two types of policy makers: hawks and doves. Which is true?

A. The size of the leftward shift of DAS in t is the same for Hawks and Doves

B. The size of the leftward shift of DAS in t is greater for Hawks than Doves

C. The size of the leftward shift of DAS in t is less for Hawks than Doves

D. The DAS shifts left only for Hawks

Answer #1

As we know that aggregate demand is the total demand for goods and services in the economy, while as aggregate supply is the total supply of goods and services. The interaction of AD-AS gives us the equilibrium. When short run equilibrium in period t-1 coincides with the long run equilibrium in period t+1 for the two policy makers Hawk and Doves than the result will be DAS will shift towards left only for Hawk.

The correct option is (D).

The DAS shifts left only for Hawks.

This leftward shift is due to higher inflation expectations.

Hope you got the answer.

Thanks!

Consider an economy that abides by a Dynamic AS/AD model as
presented in class, which, in period t-1, is in a short equilibrium
that happens to coincide with a long run equilibrium. In period t
there is a adverse supply shock. The shock remains for 2 periods
(t, t+1), but then dissipates fully in period t+2. Describe how
this economy reacts to this shock from periods t-1 through t+2.
Also discuss how the economy might transition to a LR equilibrium....

For the questions use the following scenario:
Consider an economy that abides by the standard classical model
specifications. Suppose policy makers have decided to allow a large
number of new immigrants to enter the country and join the
workforce.
In the labor market, we would expect to see
A. a leftward shift in labor demand
B. a rightward shift in labor demand
C. a leftward shift in labor supply
D. a rightward shift in labor supply
For the production function,...

in the dynamic model of AD-AS, the economy is in . long run
equilibrium in year 1 and is expected to be in short-run
equilibrium bellow potential GDP in year 2, and the federal reserve
pursues the appropriate policy, because policy will work more
quickly than the automatic adjustment mechanism this will result
in.
A) real GDP lower than what would occur if no policy had been
pursued.
B) unemployment rates higher than what would occur if no policy had...

will shift as a result of the shock and in which direction?
A.
SAS will shift Left
B.
AD will shift Right
C.
AD will shift Left
D.
SAS will shift Right
c) Illustrate the shift on your graph--again, just draw it on
your paper.
d) Explain what happens to Y, P, and the unemployment rate...

if an AD/AS model equilibrium occurs relatively far from where
the AS curve becomes steep, which of the following is/ are
true?
the economy is operating close to potential GDP
unemployment is at its natural rate
unemployment is relatively high
there is pressure on the price level
the price level is stable
the economy is operating below potential GDP
Assuming AD is unchanged, shifts in SRAS to the right lead to
a(n) _____ in real GDP and _____ pressure on...

Consider the following Keynesian (short-run) model along with
the Classical (long-run) model of the economy.
Labor Supply: Le = 11
Capital Supply: K=11
Production Function:
Y-10K.3(Le).7
Depreciation Rate: &=.1
Consumption Function: C=12+.6Yd
Investment Function: I= 25-50r
Government Spending: G=20
Tax Collections: T=20
Money Demand Function: Ld=
2Y-200r
Money Supply: M=360
Price Level: P=2

5- If an economy is in short-run equilibrium where the level of
real GDP is less than potential output, then, in the long run, one
will find:
A-Nominal wages will rise and the SRAS curve will shift left
bringing the economy back to its potential real GDP.
B-Nominal wages will rise shifting the AD curve to the right and
restoring real GDP to its potential level
C-Nominal wages will fall and the SRAS curve will shift right
bringing the economy...

When the economy is producing at an output level below the
potential output,
the unemployment rate is above the natural rate of
unemployment.
the short-run aggregate supply curve will slowly shift to the
left when wages start to adjust.
the intersection of the short-run aggregate supply curve and the
aggregate demand curve is to the right of the long-run aggregate
supply curve.
the economy might be at the long-run equilibrium.
Which of the following is not a determinant of the...
