- Consider a basket of goods that costs $72.00 in the United States. The same basket of goods costs 224.00 pesos in Mexico. The nominal exchange rate is 14 pesos per dollar. Given the information above, the real exchange rate is 4.50 baskets of Mexican goods per basket of U.S. goods. Suppose that the nominal exchange rate increases from 14.00 pesos per dollar to 28.00 pesos per dollar. If the prices of the basket remain unchanged in both the U.S. and Mexico, the real exchange rate between the U.S. and Mexican baskets of goods will change to 9.00 baskets of Mexican goods per basket of U.S. goods.
- The following table shows the nominal exchange rate, in terms of U.S. dollars per unit of foreign currency. Suppose that an handmade bookcase in Mexico is priced at 2000 Mexican pesos. The approximate U.S. dollar price of the bookcase would be $ 185.20 .
- Suppose the following transactions occur during 2012. 1. Sung, a liquor store owner in the United States, buys 50 bottles of champagne from a French vineyard at a price of $75 per bottle. 2. Autozone, a U.S. company, sells 100 spark plugs to a Korean car company at $5 per spark plug. 3. Tim, a U.S. citizen, pays $670 for a surfboard he orders from Greatwaves (a U.S. company). Based on these transactions, U.S. net exports (NX) in 2012 is $ -3250 .

- The nominal interest rate is currently 7% per year and the current expected inflation is 1%. Suppose the Fed unexpectedly increases the growth rate of the money supply, causing the inflation rate to rise unexpectedly from 1% to 3% per year. As a result of this change in inflation, the nominal interest rate will now be 9 %. Assume that the classical dichotomy holds.
- Suppose that the nominal interest rate is 7% per year. If banks and depositors expect an inflation rate of 1% per year, the expected real interest rate is 6 % per year.
- Consider a simple economy that produces only loaves of bread. The table contains information on the economy's output, money supply, velocity, and price level. For example, in 2009, the money supply was $200, the price of a loaf of bread was $5, and the economy produced 400 loaves of bread. Use the information in the table and your previous answers. The money supply grew at a rate of 8.0 % from 2009 to 2010 and the inflation rate (percentage change in prices) grew at a rate of 8.0 % from 2009 to 2010.

- Suppose that Excalibur Hotel and Casino is currently charging $150 per night. If the price of a room at the Excalibur Hotel and Casino decreases to $135, the quantity of rooms demanded at the Luxor Hotel and Casino would fall from 300 to 270 rooms per night. The cross-price elasticity of demand between these two goods is equal 1 .
- Hotels in Las Vegas draw a majority of their customers from residents of Southern California. The average household income in Los Angeles is currently $50,000 per year. At this level of income, 300 rooms are demanded per night at the Luxor Hotel and Casino. If the average household income in Los Angeles were to increase to $55,000 per year, the quantity of rooms demanded at the Luxor would increase to 340 per night. Given this information, the income elasticity of demand would be 1.32 .
