问题如下：
Daltonia is a medium sized developing country. Naim Birol, Minister of Finance for Daltonia. Birol believes Daltonia needs to address a recent increase in inflation and appreciation in the exchange rate. Should these trends accelerate, the country’s present prosperity could be threatened. Birol and his colleague Pamuk discuss policy alternatives.
Birol states: “Since Daltonia allows capital to flow freely, the clearest choice is to implement expansionary monetary and fiscal policies to stop the appreciation of the currency according to the Mundell–Fleming model.”
Pamuk replies: “The long run solution to the problem, at least according to the portfolio balance approach, would be a policy choice by the Daltonian government to run large budget deficits on a sustained basis.”
Birol adds: “There is also a timing dimension to consider. According to Dornbusch, with inflexible domestic prices in the short run, any decrease in nominal money supply will induce an increase in the domestic interest rate. This will encourage capital inflows and cause the exchange rate to overshoot to the upside in the short run, until domestic prices have a chance to react.”
Which of the statements regarding policy alternatives discussed between Birol and Pamuk in response to Daltonia’s recent increase in inflation and deterioration in exchange rate is least accurate?
选项：
A.Birol’s statement regarding Dornbusch
B.Pamuk’s statement regarding the portfolio balance approach
C.Birol’s statement regarding Mundell–Fleming
解释：
Birol’s statement regarding the Mundell–Fleming model is inaccurate because restrictive (not expansionary) fiscal policy, along with expansionary monetary policy, would lead to capital outflows and cause the currency to depreciate assuming high capital mobility.
比罗尔关于蒙代尔-弗莱明模型的陈述是不准确的，因为限制性(而不是扩张性)财政政策，以及扩张性货币政策，将导致资本外流，并导致货币贬值（假设当前资本流动性高）。
选项A虽然原理表述正确，但题目问的是要解决高汇率问题呀，A短期会因为overshoot ing进一步提高汇率，长期又不会实际影响到汇率，那么也是不能解决问题的无效理论啊，所以这题问题不对，真正解决问题的只有经常账户赤子这一个选项
