The costs and benefits of foreign borrowing: A survey of multi‐period models
综述多期外国借贷模型，探讨国家应借多少以及何时需要公共干预，分析三类模型的见解与不足。
This article surveys the literature on multi‐period models of foreign borrowing to shed light on the issue of how much a country should borrow and under what circumstances there is a role for public intervention. It identifies the essential structural elements of multi‐period models and draws out the ramifications of the alternative specifications adopted. It discusses the insights and shortcomings of three classes of models: non‐optimising, optimising borrower and jointly optimising borrower and lender.
