等式S^P=I+CA-S^g=I+CA+(T-G)=I+CA+(G-T)告诉我们，为了减少经常项目赤字，一国必须增加私人储蓄，减少国内投资或削减政府预算赤字。但是，正如我们在对20世纪80年代美国与日本经常项目案例研究中所看到的那样，许多人建议以限制从日本和其他国家的进口来减少美国的经常项目赤字。美国设立较高的进口壁垒，对美国的私人储蓄、国内投资和政府财政赤字有什么影响？你是否认为对进口限制一定会削减美国经常项目赤字？
Equation S^P=I+CA-S^g=I+CA+(T-G)=I+CA+(G-T)tells ns that to reduce a current account deficit，a country must increase its private saving，reduce domestic investment，or cut its government budget deficit．In the 1980s，many people recommended restrictions on imports from Japan(and other countries)to reduce the American current account deficit．How would higher U.S. barriers to imports affect its private saving，domestic investment，and government deficit？ Do you agree that import restrictions would necessarily reduce a U.S. current account deficit？
