Some analysts use the short-run and long-run effects on the aggregate demand–aggregate supply model to argue that expansionary m

onetary policy can’t affect employment in the long run because in the short-run monetary policy shifts the aggregate:
a. supply curve to the left, but over time the increase in prices shifts aggregate demand to the right so that GDP will end up going back to its same level of output with a higher price level.
b. demand curve to the left, but over time the increase in prices shifts aggregate supply to the right so that GDP will end up going back to its same level of output with a higher price level.
c. supply curve to the right, but over time the increase in prices shifts aggregate demand to the left so that GDP will end up going back to its same level of output with a higher price level.
d. demand curve to the right, but over time the increase in prices shifts aggregate supply to the left so that GDP will end up going back to its same level of output with a higher price level.

Answer:

D.)demand curve to the right, but over time the increase in prices shifts aggregate supply to the left so that GDP will end up going back to its same level of output with a higher price level.

Expansionary monetary policy increases money supply in the economy and thus aggregate demand increases leading to shift in demand curve to right.

Suppose that output (Y ) in an economy is given by the following aggregate production function: Yt = Kt + Nt where Kt is capital
shusha [124]

Answer:

Check the explanation

Explanation:

Yt = Kt + Nt

Taking output per worker, we divide by Nt

Yt/Nt = Kt/Nt + 1

yt = kt + 1

where yt is output per worker and kt is capital per worker.

a) With population being constant, savings rate s and depreciation rate δ.

ΔKt = It - δKt

dividing by Nt, we get

ΔKt/Nt = It/Nt - δKt/Nt ..... [1]

for kt = Kt/Nt, taking derivative

d(kt)/dt = d(Kt/Nt)/dt ... since Nt is a constant, we have

d(kt)/dt = d(Kt/Nt)/dt = (dKt/dt)/Nt = ΔKt/Nt = It/Nt - δKt/Nt = it - δkt

thus, Capital accumulation Δkt = i – δkt

In steady state, Δkt = 0

That is I – δkt = 0

S = I means that I = s.yt

Thus, s.yt – δkt = 0

Then kt* = s/δ(yt) = s(kt+1)/(δ )

kt*= skt/(δ) + s/(δ)

kt* - skt*/(δ) = s/(δ)

kt*(1- s/(δ) = s/(δ)

kt*((δ - s)/(δ) = s/(δ)

kt*(δ-s)) = s

kt* = s/(δ -s)

capital per worker is given by kt*

b) with population growth rate of n,

d(kt)/dt = d(Kt/Nt)/dt =

= \frac{\frac{dKt}{dt}Nt - \frac{dNt}{dt}Kt}{N^{2}t}

= \frac{dKt/dt}{Nt} - \frac{dNt/dt}{Nt}.\frac{Kt}{Nt}

= ΔKt/Nt - n.kt

because (dNt/dt)/Nt = growth rate of population = n and Kt/Nt = kt (capital per worker)

so, d(kt)/dt = ΔKt/Nt - n.kt

Δkt = ΔKt/Nt - n.kt = It/Nt - δKt/Nt - n.kt ......(from [1])

Δkt = it - δkt - n.kt

at steady state Δkt = it - δkt - n.kt = 0

s.yt - (δ + n)kt = 0........... since it = s.yt

kt* = s.yt/(δ + n) =s(kt+1)/(δ + n)

kt*= skt/(δ + n) + s/(δ + n)

kt* - skt*/(δ + n) = s/(δ + n)

kt*(1- s/(δ + n)) = s/(δ + n)

kt*((δ + n - s)/(δ + n)) = s/(δ + n)

kt*(δ + n -s)) = s

kt* = s/(δ + n -s)

.... is the steady state level of capital per worker with population growth rate of n.

3. a) capital per worker. in steady state Δkt = 0 therefore, growth rate of kt is zero

b) output per worker, yt = kt + 1

g(yt) = g(kt) = 0

since capital per worker is not growing, output per worker also does not grow.

c)capital.

kt* = s/(δ + n -s)

Kt*/Nt = s/(δ + n -s)

Kt* = sNt/(δ + n -s)

taking derivative with respect to t.

d(Kt*)/dt = s/(δ + n -s). dNt/dt

(dNt/dt)/N =n (population growth rate)

so dNt/dt = n.Nt

d(Kt*)/dt = s/(δ + n -s).n.Nt

dividing by Kt*

(d(Kt*)/dt)/Kt* = s/(δ + n -s).n.Nt/Kt* = sn/(δ + n -s). (Nt/Kt)

\frac{sn}{\delta +n-s}.\frac{Nt}{Kt}

using K/N = k

\frac{s}{\delta +n-s}.\frac{n}{kt}

plugging the value of kt*

\frac{sn}{\delta +n-s}.\frac{(\delta + n -s)}{s}

n

thus, Capital K grows at rate n

d) Yt = Kt + Nt

dYt/dt = dKt/dt + dNt/dt = s/(δ + n -s).n.Nt + n.Nt

using d(Kt*)/dt = s/(δ + n -s).n.Nt from previous part and that (dNt/dt)/N =n

dYt/dt = n.Nt(s/(δ + n -s) + 1) = n.Nt(s+ δ + n -s)/(δ + n -s) = n.Nt((δ + n)/(δ + n -s)

dYt/dt = n.Nt((δ + n)/(δ + n -s)

dividing by Yt

g(Yt) = n.(δ + n)/(δ + n -s).Nt/Yt

since Yt/Nt = yt

g(Yt) = n.(δ + n)/(δ + n -s) (1/yt)

at kt* = s/(δ + n -s), yt* = kt* + 1

so yt* = s/(δ + n -s) + 1 = (s + δ + n -s)/(δ + n -s) = (δ + n)/(δ + n -s)

thus, g(Yt) = n.(δ + n)/(δ + n -s) (1/yt) =  n.(δ + n)/(δ + n -s) ((δ + n -s)/(δ + n)) = n

therefore, in steady state Yt grows at rate n.

The aggregate demand curve shows a _____ relationship between _____ and _____ at a given spending growth.
rewona [7]

The aggregate demand curve shows a relationship between aggregate price level and demand at the given spending growth.

<h3>What is demand?</h3>

Demand is explained as the requirement of a certain product in the market, usually this demand is varied if the prices are changed and the demand also is impacted by the supply.

If the prices are high it is highly likely that the demand of that product will reduce if the product is not a necessity.

If the prices are lower the demand for the product will increase.

How important is structure/culture compared to the other primary internal considerations for a strategic plan?
ZanzabumX [31]

Explanation:

The organizational structure and culture are essential for the design of a strategic plan aligned with the organization's purpose.

What happens is that the structure and culture of an organization constitute its identity, its way of organizing itself and creating an environment designed to obtain the objectives and goals stipulated by strategic planning. So it can be said that there is no way to develop a strategic plan without considering the structure or culture, because it is through these two variables that action plans are developed and modeled according to what the company is, and what it plans to be in the future. All organizational systems must be foreseen in the planning and be developed with the same degree of importance, because together they form the organizational whole that will lead a company to be well positioned in the market, achieve continuous improvement in its processes, achieve competitive advantage in the market, etc.
