The figure below illustrates the U.S. current and capital account balances since 1980. As you can see, the two accounts are basically mirror images of each other. In 1991, both the current account and capital account balances were roughly zero. The increase in the current account deficit from 1991 to 2006, for example, is matched by an increase in the capital account surplus. To make things simple, assume that the current account includes only the value of exports and imports, and the capital account includes only payments for real and financial assets.

Suppose that Americans buy $10 mil lion worth of cars manufactured in Germany. If Germans use the $10 million to buy air conditioners manufactured in America, both the US. current account balance and the U.S. capital account balance are equal to $ million. Part 2 (2 points) 0 See Hint Suppose instead, the German holders of the $10 million in U.S. dollars purchase shares of General Electric stock. The U.S. current account balance would be equal to $ million, and the U.S. capital account balance would be equal to $ million.
