短期固定价格模型中，减少货币供给将提高名义利率并使通货升值。在这种情况下，预期实际利率会发生什么变化，请解释为何实际汇率的随后变化满足实际利率平价的条件。

  In the short run of a model with sticky prices，a reduction in the money supply raises the nominal interest rate and appreciates the currency．What happens to the expected real interest rate？ Explain why the subsequent path of the real exchange rate satisfies the real interest parity condition．
