Calculate MPC when a change in investment spending of 40 million leads to an increase in real GDP by 160 million.
Suppose the marginal propensity to consume is 0.8, the marginal propensity to import is 0.2, and autonomous expenditure is 300. What
is the equilibrium value of GDP?
Answer:
With an MPC of 0.8, government spending increases $20 billion while taxes decrease $10 billion. Based on this data, what is the cumulative effect on GDP?
