the following the average marginal propensity to consume (MPC)
is c1 = .52.
They then looked at how different groups had different marginal
propensities to consume. In particular:
- For Group 1 of Italians, their MPC is c1 = .3
- For Group 2 of Italians, their MPC is c1 = .65
Now, take the following hypothetical situation about the Italian
economy:
M = X = 0
G = 500, Tp=500
C = 1000 + c1(Y-Tp)
I = 200
Round to two decimal places in answers below:
- First let’s imagine all Italians have the average MPC of
c1 = .52
- What is the equilibrium level income?
3000
- If the gov’t increases spending by 200, what is the new
equilibrium level of income? 3416.67
- What is the multiplier on government spending?
2.08
- If government spending stays at 500, and instead they lower
personal taxes by 200, why is the new equilibrium level of income?
3216.67
- What is the multiplier on the tax
reduction?-1.08
- Which multiplier is larger? multiplier on govt spending
is larger
- Why are they different? portion of increase govt
spending is consumed resulting in lower taxes?
- Now, let’s look at the effect of difference in MPC.
- Fill out the following table (your answer for all Italians
should come from question 1)

- Discuss the differences in multipliers. In words (not math!),
how does the MPC relate to the multiplier?
- Group 1 and Group 2 are two mutually exclusive collections of
people in the Italian economy that have different consumption
habits (this could be based on geography, age, income level,
education, et) Make an educated guess about who belongs to each
group. Then explain your reasoning.
