Q

• Minimum Wage Laws:

A

“if the wage is kept above the equilibrium level for any reason, the result is unemployment”
• Applies only to low-skilled workers
• An extremely emotive issue
• Does reduce the growth in employment, but doesn’t “kill jobs”

Q

• Why does the AD curve have a negative slope?

A

• Aggregate Wealth Effect: price goes up, real wealth goes down, consumption spending goes down, GDP goes down

Exchange Rate Changes: if price goes up, Canadian goods and services become less competitive, net export spending goes down, GDP goes down
• Price goes up, GDP goes down (vice versa)

Q

Shifts in the AD curve:

A
  • Any factor except price which causes an increase in expenditure (I, X, G, C) will shift the AD curve to the right
  • Any factor except price which causes expenditure to decrease (Im, T, S) will shift AD to the left
  • Injection increases, withdrawal decreases
  • ANY change in price means move along the AD curve

Q

Aggregate Supply:

A

•
2 types: SRAS, LRAS

Positive because any short run aggregate supply curve, physical productivity and input prices are held fixed

Price goes up, its more or less profitable to produce, so GDP goes up

Q

Q

• Long run AS:

A

• Is a vertical P-GDP space at the natural rate of output where production factors are fully employed
• The vertical form implies that there is no mathematical relationship between the two variables

16
Q

• Why is the LRAS vertical?

A

• The long-run equilibrium level for real GDP depends on the factor endowments of land, labour, capital, and the technology of production, which have nothing to do with the price level
•
Input prices, especially wages, eventually catch-up to any change in output prices, and thus the aggregate output level will end up where it started

Q

• Shifts in the LRAS curve:

A
  • The natural rate of output also called potential GDP
  • This is thought to be the long-run equilibrium for real GDP
  • Same factors cause LRAS to shift as SRAS, EXCEPT for changes in wages or other input prices
  • LRAS will expand (contract), and the curve will shift to the right (left) if there is an increase (decrease) in any of the endowments of the factors of production, or if there is an improvement in the technology of production

Q

• Positive shock to AD:

A

spending goes up, aggregate demand shifts right, equilibrium price and quantity go up
• Due to great times, there is upward pressure on wages
• This causes SRAS to go right, EQ price goes up, Q goes down
• Eventually we end up back at potential GDP

19
Q

• Negative shock to AD:

A

spending goes down, so AD goes down (AD shifts left)
• Equilibrium price, quantity goes down
• Economy enters a recession
• Due to hard times, after a long adjustment period, there is a downward pressure on wages
• Causes SRAS shift right
• Equilibrium P goes down, Quantity goes up
• Eventually, recession ends, and the real GDP grows back to its natural rate

20
Q

• Negative Shock to AS:

A

at each possible price, production costs rise, causing SRAS shift left
• Equilibrium price up, quantity down
• Called stagflation

21
Q

Positive shock to AS (temp)

A

output increases and price decreases

22
Q

The classical and neo-classical approaches

A
  • both recommend that the economy be allowed to right itself
  • Hard times cause wages and input prices to fall
  • SRAS expands
  • After a long, painful adjustment period, price goes down and quantity goes up
  • One way to remedy the situation is for the government to cause an increase in AD
  • AD shifts right, equilibrium P and Q go up
  • End up with even higher prices than before, but the economy is back to its natural state of output
23
Q

• Negative shock to LRAS:

•

A

climate change

24
Q

Stabilization Policy:

A

• Deliberate, conscious effort of the government to intervene in the macroeconomy with an eye toward influencing the course of Equilibrium P or Q (real GDP)

25
Q

Monetary policy

A

• is executed by the bank of Canada

26
Q

Fiscal policy

A

• is carried out by finance departments, and involves changing T and/or G

27
Q

• Expansionary fiscal policy

A
  • to stimulate AD, the government either increases G and/or cuts taxes
  • Causes AD to shift right
  • P, Q go up
28
Q

Contractionary fiscal policy

A
  • to contract AD, the government either decreases G and/or raises taxes
  • causes AD to shift left
  • P, Q go down
29
Q

• Multiplier Effect:

A
  • The basic idea is that if the government increases spending (which it is doing now), this increase in spending has an effect on AD that causes it to expand again and again
  • Ultimately by much more than the initial expansion of AD
  • Geometrically, it is the magnitude of the horizontal shift in AD
30
Q

• Interpretation of multiplier effect

A

the change in total spending (C + I + G + NX) which results from a $1 change in government spending.

31
Q

• ***Exam Question: why the multiplier is important:

A

the higher the value for the multiplier, the more powerful; fiscal policy will be, and conversely the lower the value of the multiple, the less potent fiscal policy will be***

32
Q

• (MPC) marginal propensity to consume =

A

fraction of each additional $ of income that goes to consumption spending as opposed to saving
• Suppose MPC = 0.8, no imports, taxes, and that G increases by $100 million
• Same value as in the textbook
• spending increases immediately by $100 million in round #1
• The initial impetus of D G triggers a RIPPLE effect of successive rounds of changes in induced spending
• Each induced increase to spending gets smaller and smaller
• Therefore, the cumulative sum of the changes in spending approach a limit, and AD will stop shifting

33
Q

• The higher the value of the MPC:

A
  • the higher the value of the multiplier, as less income leaks out of the circular flow in the form of savings
  • The higher the impact of a change in G on aggregate expenditure
34
Q

• Midterm what is the relationship between MPS and MPC

A

they are directly correlated, MPS goes up, MPC goes down

• MPC shows the higher the impact of change in G on aggregate expenditure

35
Q

• fiscal policy is good because:

A
  • effective means to remedy the negative economic shocks, simulative fiscal policy is an increase in government spending and/or decrease taxes
  • all about simulative fiscal policy when the economy is in a negative output gap, lower level of GDP than the natural GDP, LORD KEYNES over to you
36
Q

• fiscal policy is bad because:

A

Argue that the lags are long (the time between the occurrence of the negative shock and the intervention)
• Information lag
• Formulation lag
• Implementation lag
• By that time, the intervention might no longer be appropriate
• Tend not to have faith in the efficacy of government to accomplish anything
•

37
Q

• Automatic Stabilizers:

A

• Automatic stabilizer is fiscal policy that is built into the government’s tax and expenditure apparatus that self-activates
• When in a recession, UI payments increase and total tax revenue decreases
• • This causes AD right
• But not sufficient to bring about an end to the
•
• recession
– When beyond potential GDP, UI payments
• decrease and total tax revenue increases
This causes AD left
•

38
Q

• Deficits and Debt:

A
  • Fiscal Deficit=T–G<0

* Fiscal Surplus=T–G>0

39
Q

Debt is…

A

• a STOCK quantity referring to
• total amount owed
– No time frame
– Sum of all prior deficits and surpluses

40
Q

Deficit is…

A
  • a FLOW quantity referring to shortfall PER TIME PERIOD
  • Benefits of debt-financed deficits
  • – VERY politically popular because it’s “free extra spending”
  • – Address negative AD and/or SRAS shocks
  • – Can finance investments in infrastructure that
  • increase AS in both the short-run and the long-run
  • If it’s PRODUCTIVE public investment
41
Q

The Keynesian view is

A

that macroeconomy is inherently vulnerable and unstable. Sometimes it performs well on its own, but often it does not. The government should frequently intervene in the form of fiscal and/or monetary policy in order to stabilize the macroeconomy.

42
Q

stagflation

A

high inflation despite low economic growth and high unemployment

43
Q

Ricardian equivalence

A

• Ricardian equivalence means when the government generates a ton of debt, people see that taxes will increase in the future and they will save more

44
Q

3 lags in fiscal policy

A

informational
formulation
implementation

45
Q

Why is tax multiplier negative?

A

It’s a leakage/withdraw from the circular flow, as are savings, imports.

46
Q

Multiplier formula for government spending

A

1/(MPC-1)
