Document Summary

Nco-net capital outflow (savings - investment = nco = nx) Is: y = c + i(r) + g + nx(e(r)) Net exports is an decreasing function of the exchange rate. The exchange rate is a positive function of the interest rate. Investment is a decreasing function of interest rate. Week 8 page 1 r = r* + Lm* shifts right because y goes up to offset rise in r. In the short run, gdp (y) goes up. Decrease in e causes net exports to increase. Investment is decreasing due to increase in r. Nx increases enough to offset decrease in investment. It is not a good idea to be seen as a risky country and investments will eventually settle down or decrease. 3 policy choices can"t have all 3 at same time, only 2. If prices are higher than expected, y would be greater than y. If prices are lower than expected, y would be less than y.
