Most people are familiar with the nominal exchange rate, the price of one currency in terms of another. It's usually expressed as the domestic price of the foreign currency. So if it costs a U.S. dollar holder $1.36 to buy one euro, from a euroholder's perspective the nominal rate is 0.735 euros per dollar. But the nominal exchange rate isn't the whole story. The person or firm buying another currency is interested in what can be bought with it. Are they better off with dollars or euros? That's where the RER comes in. It seeks to measure the value of a country's goods against those of another country, a group of countries, or the rest of the world, at the prevailing nominal exchange rate. are increase $679
