9
Q

Why is the AS curve upward sloping?

A

Because firms will produce more output only if prices
increase to offset higher unit costs.

Q

Why is the AS curve relatively flat when GDP is low?

A

When firms have excess capacity
and
are able to expand production with little or no increase in unit costs (demand determined)

Q

What is the AD curve?

A

The curve showing the combinations of real GDP (x axis) and Price level (y axis) for which
Desired AE = Actual National Income

16
Q

Why is the AD curve negatively sloped (2)

A
  1. Fall in the price level = rise in private-sector wealth –> increases desired consumption –> increase in equilibrium GDP
  2. Fall in the price level = rise in net exports and thus leads to an increase in equilibrium GDP

18
Q

What does the simple multiplier measures for the AD curve

Study These Flashcards
A

It measures the horizontal shift in response to changes in the autonomous desired expenditure

19
Q

A decrease in factor prices leads to what for the AS curve?

Study These Flashcards
A

Shifts the curve downward to the right

(real GDP will increase for the same price level)

20
Q

What is a deterioration in technology?

Study These Flashcards
A

change in production methods that RAISES unit costs for any given level of output

21
Q

What is an improvement in technology?

Study These Flashcards
A

change in production that REDUCES unit costs for any given level of output

22
Q

What happens to the AS curve when there is an improvement of technology?

Study These Flashcards
A

The curve shifts downward to the right

(increase in AS, real GDP increases for the same price level)

23
Q

What happens to the AS curve if there is an increase in Canadian exports?

Study These Flashcards
A

Movement upward to the right along the AS curve

24
Q

What are the 3 things explaining the positive slope of the AS curve?

Study These Flashcards
A
  1. The law of diminishing marginal returns
  2. The behaviour of profit-seeking firms
  3. The rising unit costs associated with rising output levels
25
What is the law of diminishing returns
Unit costs tend to rise as output rises As investment in a particular area increases, the rate of profit from that investment, after a certain point, cannot continue to increase.
26
What happens to the AS curve when wages rise faster than the increase in labor productivity?
AS curve shifts upward
27
What does macroeconomic equilibrium determines?
Equilibrium levels of price and GDP
28
Macroeconomic equilibrium occurs at the intersection of what?
The AS and AD curves
29
What are the 2 conditions for a macroeconomic equilibrium?
1. At the prevailing price level, desired AE must be equal to actual GDP --> this condition holds along the AD curve 2. At the prevailing price level, firms must want to produce the prevailing level of GDP, no more, no less --> this condition holds along the AS curve
30
What will a positive shock cause to the AD curve, the GDP, and the Price level
A shift the the right Price level increase Real GDP increase Price level and GDP in same direction Events sifting the AE up will shift the AD to the right
31
What will a positive shock cause to the AS curve, the GDP, and the Price level
A shift to the right Price level decrease Real GDP increase Price level and GDP in opposite directions
32
The multiplier when the price level varies is smaller or bigger than the simple multiplier?
Smaller
33
Why is the multiplier smaller when the price level varies?
Because an increase in autonomous expenditure cause the AE to shift up but the increase in price level causes it to shift down a little
34
The steeper the AE curve, the _______ the price effect and the _______ the GDP effect
greater smaller
35
When does a recessionary gap occur?
When actual level of output is less than the potential one
36
When the AS curve is flat, the multiplier is ______ than when it's not flat
Larger
37
What is stagflation
The particular​ case where both inflation and unemployment​ rise
38
A variable price level ... the value of the multiplier
reduces
39
Aggregate supply shocks cause the price level and real GDP to change in _______ directions
opposite
40
The aggregate demand curve shows the relationship between
the price level and the quantity of real GDP demanded
41
The COVID-19 pandemic created what regarding AS and AD shocks
A combined negative AS shock and negative AD shock
42
Aggregate demand shocks cause the price level and real GDP to change in _______ directions
same
43
For a country that uses oil as an input, an unexpected change in the price of oil would be called __________ by economists (assume the country does not produce and export oil).
A supply shock
44
For countries such as Canada that also produce and export oil, a decrease in the price of oil causes a reduction in income to domestic oil producers and is thus a _________
negative aggregate demand shock
