The U.S. is often blamed for triggering the 2008 global financial crisis because many of the excesses and bad practices originated in the U.S. The crisis has had consequences on all aspects of the global economy. According to a recent report by Brookings Institute, the U.S. economic crisis is linked to a huge drop in world trade. Since U.S. imports have been an important component of world demand, a drop in imports has had repercussions in its exports. Rami Horowitz is a young economist working for a trade policy institute. He wishes to analyze the changes in U.S. imports and exports based on the data in the accompanying table. Both real exports and imports represent quarterly, seasonally adjusted values, measured in billions of 2005 dollars. A portion of the data is shown below; the complete data set can be found on the text website, labeled World Trade.

U.S. Real Exports and Imports

Period	Real Exports	Real Imports
2007: Quarter 1	1485.9	2190.8
2007: Quarter 2	1504.8	2188.1
....	....	....
2009: Quarter 4	1555.5	1902.7

In a report, use the sample information to:

1. Create simple indices for real exports and real imports with Quarter 1, 2007, used as the base period.

2. Interpret the percentage changes in real exports and real imports over the three-year period.
