Q

Main determinants of consumption

A
  1. Current income
  2. Future income
  3. Wealth
  4. Interest rate
  5. Taxes
18
Q

The Keynesian Consumption Function

A

Expresses consumption as a function of current disposable income

C= a + BY^d

Y^d is disposable income
a is autonomous consumption
B is marginal propensity to consume

19
Q

Autonomous consumption

A

It is the level of consumption that does not depend of income

20
Q

Marginal Propensity to Consume

A

Measures the change in consumption per unit change in income.

21
Q

Properties of the Keynesian Consumption Function

A
  1. MPC is constant

2. Average Propensity to Consume decreases with income. [see notes]

22
Q

Factors that determine investment

A
  1. The user cost of capital (real interest rate)
  2. Business expectation about the future prospects of the economy
  3. Taxes
  4. Investment tax credit
23
Q

The Keynesian Savings Function

A

[- a + (1 - B) Y^d]

-a is autonomous dissaving
(1 - B) is marginal propensity to save.

24
Q

Investment tax credit

A

An amount that businesses are allowed by law to deduct from their taxes, reflecting an amount they reinvest in themselves

25
Q

Net exports depends on

A
  1. Domestic income
  2. Foreign income
  3. Real exchange rate
26
Q

The real exchange rate

A

The real exchange rate measures the price of foreign goods relative to the price of domestic goods.

27
Q

Mathematically, real exchange rate is

A

The ratio of a foreign price level and the domestic price level, multiplied by the nominal exchange rate.

28
Q

Fiscal policy

A

Refers to the changes in the level of government spending and/or taxes meant to influence the level of economic activity.

29
Q

Types of fiscal policy

A
  1. Expansionary policy (fiscal loosening)

2. Contractionary policy (fiscal tightening)

30
Q

Expansionary policy (fiscal loosening)

A

refers to increases in government spending or reduction taxes

31
Q

Contractionary policy (fiscal tightening)

A

Refers to increases in government taxes and/or reduction in government spending. Fiscal austerity

32
Q

Austerity

A

A set of economic policies a government implements to control public sector debt.

33
Q

Output (GDP) Gap

A

The difference between what the economy could have produced and what actually is produced thus, potential output minus actual output

34
Q

If output gap is positive i.e potential GDP is greater than actual GDP

A

We have recessionary gap

35
Q

If output gap is negative i.e potential GDP is less than Actual GDP

A

We have inflation gap

36
Q

If output gap is zero i.e potential GDP is equal to actual GDP

A

We have full employment

37
Q

Major goal of fiscal policy

A

Is to stabilize actual output close to the potential output

38
Q

[T /F] If actual output is greater than potential output (inflationary gap), contractionary fiscal policy can be used to reduce output to potential output

A

True

39
Q

[T /F] If actual output is less than potential output (recessionary gap), expansionary fiscal policy can be used to increase output to the full employment output

A

True

40
Q

Automatic stabilizers

A

In-built fiscal mechanisms within an economy that dampens effects of fluctuations in aggregate demand on actual output. Example, unemployment insurance

41
Q

Crowding out

A

Refers to offset in aggregate demand that results when expansionary fiscal policy raises the interest rate and thereby reduce investment spending.
