Assume both home and the rest of the world is in recession. If the home country wants to use monetary policy to stimulate its economy, would that intervention be more effective or less effective if the rest of the world: (a)used fiscal policy, (b) also used monetary policy, or (c) did nothing? Consider how foreign intervention would affect YROW (income in rest of the world), WIR (world interest rate), and the exchange rate from the rest of the world's point of view, which is the inverse of ER (foreign exchange rate). Then consider how those three effects would affect the home country. Which foreign intervention is best for the home country?
