Current-Account Effects of a Temporary Change in Government Expenditure
用完美预见模型分析政府支出暂时增加对经常账户的影响，发现私人消费边际效用与公共品供给的关系决定最优经常账户反应的性质，并考察政策变化时机与效应大小的联系。
A perfect-foresight model of intertemporal utility maximization is used to analyze the current-account effects of a temporary increase in government spending. The relationship between the marginal utility of private consumption and the supply of public goods in the economy is shown to play a crucial role in determining the qualitative nature of the optimal current-account response. The link between the timing of the policy change and the magnitude of the current-account effect is also examined.
