If the domestic money supply is too high, people will spend the excess abroad, buying foreign currency with home money to enable those purchases. This will cause the price of foreign currency in terms of domestic currency to be bid up.

We see that at initial RER er0trade is balanced, i. The Determinants of the Nominal Rate of Exchange: So long we were concerned with the determination of the RER and its effect on trade balance and social welfare. Now we examine how the nominal exchange rate NER is determined. The NER is written as: Since a pound is worth less, it will buy fewer dollars. This means that the dollar is worth less, a pound will buy more dollars. Since the foreign exchange market is dynamic, economists find it interesting to study exchange rate movements over time.

The above equation can now be expressed as: Thus, percentage change in NER between pound and dollar equals the percentage change in RER plus the difference in rates of inflation in the two countries. If a foreign country the USA has a higher lower rate of inflation than UK the home country a pound will buy a larger smaller amount of a foreign currency dollar over time.
