Question

Quizplus · Accepted Answer

The government purchases multiplier can be calculated using the formula: 1 / (1 - MPC(1 - Tax Rate) + MPI), where MPC is the marginal propensity to consume, MPI is the marginal propensity to import, and the Tax Rate is the proportion of income paid as taxes. Plugging in the given values: 1 / (1 - 0.8(1 - 0.1) + 0.2) = 1 / (1 - 0.8*0.9 + 0.2) = 1 / (1 - 0.72 + 0.2) = 1 / 0.48 = 2.1.
