Question:

In the United States€™ currency union, we seem never to worry if a state has a big current account deficit. Have you ever seen such data in the newspaper? Can you even find the data in any U.S. government statistical sources? For example, one would guess that the state of Louisiana ran large current account deficits after it was devastated by Hurricane Katrina in 2005. But Louisiana€™s possible current account deficit was not deemed worthy of coverage by the financial press. We do know, however, that in 2008, Greece had a current account deficit of 14.6 percent of GDP, Portugal had a deficit of 12 percent of GDP, and Spain had a deficit of 9.8 percent of GDP (Table). Should the governments of these countries worry about such large deficits?
