Consider an open economy representing a three-sector
macroeconomic model: C = 150 + 0.6 (Y - T); I = 350; G = 400; X - M
= 250 and MPI = 0.07, where C is consumption, I is planned
investment, G is government expenditure, (X - M) is net exports,
and MPI is the marginal propensity to import. Assuming there are no
taxes, what is the multiplier with imports?
