本章讨论的“通货膨胀偏向和政策制定中的其他问题”提出，或许不会有真正的这种永久的财政扩张。

你怎样认为？这些考虑是如何影响汇率和财政政策的产出效果的？你认为与本章讨论的经常项目不平衡引起的长期影响有什么相同之处吗？

The chapter's discussion of“Inflation Bias and Other Problems of Policy Formulation” suggests (paragraph 4) that there may not really be any such thing as a permanent fiscal expansion. What do you think？ How would these considerations affect the exchange rate and output effects of fiscal policy？ Do you see any parallels with the chapter's discussion of the longer-run impact of current account imbalances？
