Abstract: This paper extends the Sidrauski's approach to two currencies in a small open economy. Following Sidrauski's solution procedure, we derive a macroeconomic model that is usually found in some ad hoc models of perfect foresight. It turns out that an implicit assumption of fixed future expectations on the future price inflation is imposed on the household's behavior. We also show that unexpected and permanent increases in government expenditure cause the exchange rate to rise. Whether there is initial overshooting in the exchange rate depends on the relative shifts in "m" [equal to] 0 and "F" [equal to] 0 schedules. Furthermore, it is shown that when the government announces its future increases in the government expenditure, the domestic currency depreciates immediately and the foreign exchange accumulates thereafter.
