Intuition for the shift in IS*:
At a given value of e (and hence NX), an increase in G causes an increase in the value of Y that equates planned expenditure with actual expenditure.
Intuition for the results:
As we learned in earlier chapters, a fiscal expansion puts upward pressure on the country’s interest rate. In a small open economy with perfect capital mobility, as soon as the domestic interest rate rises even the tiniest bit about the world rate, tons of foreign (financial) capital will flow in to take advantage of the rate difference. But in order for foreigners to buy these U.S. bonds, they must first acquire U.S. dollars. Hence, the capital inflows cause an increase in foreign demand for dollars in the foreign exchange market, causing the dollar to appreciate. This appreciation makes exports more expensive to foreigners, and imports cheaper to people at home, and thus causes NX to fall. The fall in NX offsets the effect of the fiscal expansion.
How do we know that Y = 0? Because maintaining equilibrium in the money market requires that Y be unchanged: the fiscal expansion does not affect either the real money supply (M/P) or the world interest rate (because this economy is “small”). Hence, any change in income would throw the money market out of whack. So, the exchange rate has to rise until NX has fallen enough to perfectly offset the expansionary impact of the fiscal policy on output.
