Q

In the SOLOW MODEL
What happens if the saving rate (s) increases ?

A

sY curve shift upward
So Inet increase
But consumption decrease
K* and Y* increase
So Y increase until we get to the new steady state

Q

In the SOLOW MODEL
What happens if the depreciation rate (d) increases ?

A

dK curve became more vertical
So Inet decrease
But consumption don’t change
K* and Y* decrease
So Y decrease until we get to the new steady state

Q

In the SOLOW MODEL
What happens if A or Kh increase ?

A

Both Y curve and sY curve shift upward
So Inet increase
But consumption don’t change
K* and Y* increase
So Y increase

Since we can increase technology with no limit, A is the key to having a continual growth

Q

In the PPC MODEL
What is the type of curve and why ?

A

It’s a concave curve (since it’s not always a constant trade off)

Q

In the PPC MODEL
What happen if the economy is on the PPC curve ?

A

To produce more good X one must sacrifice production of good Y

To produce more good Y one must sacrifice production of good X

There is an opportunity cost (OC) because ressources must be reallocated from one sector to another

Q

In the PPC MODEL

Q

In the PPC MODEL
What happen if the economy is outside the PPC curve ?

A

It is not feasible

Q

In the PPC MODEL
What happen if we increase technology (productivity in one good) ?

A

It is only the X that increase

That allow the achievement of a previously impossible production (initially outside the PPC curve)

Q

In the PPC MODEL
What happen to the OC of a good if we increase technology (increase of productivity in the other good) ?

A

If we increase the productivity of X for exemple then the OC of Y increase

Q

In the LABOUR MARKET MODEL
What is the effect of a wage increase ?

A

Above the equilibrium wage (w*)
Ls > LD

Q

In the LABOUR MARKET MODEL
What is the effect of a wage decrease ?

A

Under the equilibrium wage (w*)

AD and SRAS curves are affected If there is a change in oil price that mean there is a change in production cost so production is less favorable but investment become more interesting If P increase then SRAS shift to the left and AD shift to the right If P decrease then SRAS shift to the right and AD shift to the left
63
In the AGGREGATE SUPPLY AND AGGREGATE DEMAND MODEL (closed economy) How does a change in production capacity (A) affect the curves ?
LRAS and SRAS curves are affected If there is a change in productivity that mean there is a change in Y and Yp If productivity increase then SRAS and LRAS shift to the right by the same proportion If productivity decrease then SRAS and LTAS shift to the left by the same proportion
64
In the AGGREGATE SUPPLY AND AGGREGATE DEMAND MODEL (closed economy) How does a change in production cost affect the curves ?
Only SRAS curve is affected If there is a change in production cost but prices don’t change it makes production less or more favorable If production cost increase then SRAS shift to the left If production cost decrease then SRAS shift to the right
65
In the AGGREGATE SUPPLY AND AGGREGATE DEMAND MODEL (closed economy) How does a change in money supply m affect the curves ?
If there are more money supply that decrease the interest rate but if there are less money supply that increase the interest rate An increase in the interest rate make AD shift to the left An decrease in the interest rate make AD shift to the right
