Nominal and Real Exchange Rates of an Open Economy (With Formula)
Nominal Versus Real Exchange Rates. Nominal Exchange Rate. Nominal exchange rates simply refer to the quoted rates we observe in the market. The usual distinction is between nominal exchange rate and real exchange rate. Thus we can write the functional relationship between RER and NX as. This study investigates the relationship between nominal and real effective exchange rates. Both short run and long run relationships between the two are.
This relationship is called the law of one price. If every good produced in the domestic economy is also produced in the foreign economy, and if the shares of each good in aggregate output are the same in both economies, then the domestic price level will equal the exchange rate times the foreign price level.
Suppose that the government decides to fix the price of its currency in terms of some foreign currencythat is, adopt a fixed exchange rate. By fixing the exchange rate, the domestic authorities tie their hands with respect to monetary policythey are forced to create a specific equilibrium nominal money supply. As a matter of policy, the government can control either the domestic money supply or the country's exchange rate but not both.
What is the nominal and real exchange rate? - Czech National Bank
When the government fixes the exchange rate, it invokes a natural mechanism that keeps the domestic money supply at its equilibrium level. In order to fix the exchange rate, the government must stand ready to purchase or sell domestic currency for foreign currency at its announced price.

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. To maintain the exchange rate at the official level, the government has to sell foreign currency for domestic currency, taking home money out of circulation in the process. For the purpose of doing this, it keeps reserves of foreign currency on handthe country's stock of foreign exchange reserves.
If the domestic money supply is too low, the opposite will happen.

Too much will be sold abroad and people will be exchanging too much foreign currency for domestic currency. The government has to buy foreign currency to keep the price of foreign currency in terms of domestic currency from falling below the official level.
This increases the country's stock of foreign exchange reserves and puts additional domestic money in circulation. The government can choose, of course, to not purchase and sell foreign currency for domestic currency when there are excess sales or purchases by domestic residents abroad.
So it measures the purchasing power of domestic currency to the foreign currency at a prevailing time. Real exchange rate is highly affected by the change in the exchange rate in the global market. How to calculate Real exchange rate: The formula of real exchange rate: Same as the Real exchange rate this exchange rate is also used to buy and sell the goods and services in the international market with another country.

Nominal exchange rate means a rate by which you can exchange your domestic currency with the foreign currency at any financial institutions like banks, NBFCs etc.
It is the value of money which is received in an exchange with another currency. If RER is high, domestic residents the Britishers will want to buy many imported goods and foreigners the Americans will want to buy few British goods.
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.
