Explanation / Answer

A $500 billion increase in investment spending causes the equilibrium income in the country of Oncy to rise by $5,000 billion.

What is the marginal propensity to consume in this economy?

1/MPS = 1/(1-MPC) is known as the spending multiplier

so

10 = 1/MPS

MPS = 1/10

So MPC = 9/10


A. 0.9

B. 0.6
