1. Marginal Propensity to Consume

Laughlandia’s consumption schedule is given in the table below (in millions of dollars).

GDP=DI

C

1660

1668

1680

1684

1700

1700

1720

1716

1740

1732

1760

1748

1780

1764

1800

1780

Use the information to answer the following:

a.     If GDP which equals disposable income is $1680 how much is saved?

b.    What is the "break-even" level of disposable income?

c.     What is this economy's marginal propensity to consume?

d.    What is the average propensity to consume when disposable income is $1700? When disposable income is $1800?

e. What is the simple spending multiplier in this scenario

2. Explain what the simple spending multiplier is and the relevance of the marginal propensity to consume. Give examples.

3. Draw a consumption function. What is the relationship between the consumption function and Aggregate Demand?

Explanation / Answer

1

a)

Saving = 1680 – 1684

           = - 4

b)

Break even disposable income reaches where disposable income is equal to consumption.

Thus, breakeven disposable income here is:$ 1700

c)

Marginal Propensity to Consume (MPC) = Change in Consumption / Change in DI

= 16 /20

= 0.8

d)

Average propensity to Consume (APC) When income is 1700: 1700/1700 = 1

APC when income is 1800 : 1780/1800

                      = 0.98
