灵活的价格货币模型成为了解汇率的重要模型（Devereux＆Engel，2003）。确定汇率的货币模型从有关完美资本流动的假设开始。两个重要的术语包括PPP和用于确定均衡条件的利率平价条件（Girton＆Roper，1977）。
模型的主要组成部分假设购买力平价持续不变。
St = Pt-P * t + C

在上面的等式中，“C是一个常数，S是以外币为单位表示的每种外币的汇率的对数，P和P *是国内和外国的价格水平。在C = 0的情况下，等式将实现PPP的绝对值保持，如果c不等于0，则表示相对PPP成立。
该模型的次要模块假设在国内和国外都可以实现稳定的货币需求。货币汇率决定的市场条件取决于实际收入的对数y和价格水平p和名义利率i的对数。除此之外，为了计算外币汇率，可以考虑这个模型来假设一个相同的关系。
在等式中，外部变量通过使用星号来测量。

“The flexible price monetary model”
The flexible price monetary model emerged as a vital model for understanding of the exchange rate (Devereux & Engel, 2003) . The monetary models for the determination of the exchange rates starts with the assumptions related to the perfect capital mobility. Two important terms includes the PPP and the interest rate parity conditions which are used for the determination of the equilibrium conditions (Girton & Roper, 1977).
The primary block of the model assumes that the purchasing power parity is held in a continious manner.
St = Pt – P *t + C

In the above equation, ‘C is a constant, S s the logarithm of the rate of exchange which is expressed in units of home currency for every foreign currency and P and P* are the domestic and foreign levels of price. In case the value of C=0, equation would implement that absolute value of PPP holds and if c is not equal to 0 it states that relative PPP holds true.
The secondary block for the model assumes that the stable money function for demand is possible both in case of domestic countries and foreign nations. The market conditions in which money exchange rates are determined is dependent on the logarithm of the real income, y and the logarithm of the price level, p and nominal interest rate, i. In addition to this, for the calculation of the exchange rate for foreign currency an identical relationship can be assumed by considering this model.
In the equations the foreign variables are measured by the use of asterisk.
