But then in April of 1985 the dollar began a sharp decline. The dollar's trade weighted value fell 23 percent in just 12 months and by a total of 37 percent by the beginning of 1988.
Although economists have studied the sensitivity of import and export volumes to changes in the exchange rate, there is still much uncertainty about just how much the dollar must change to bring about any given reduction in our trade deficit.
Even if the dollar does decline during the coming months, the delays in the response of exports and imports to the more competitive dollar will mean that the increase in aggregate demand from this source may not happen for a year or more.
In short, both experience and economic theory imply that the US could now t to a more competitive dollar without experiencing either increased inflation or decreased economic growth.
But the primary reason for wanting the dollar to become more competitive in the near future is that we may need an increase in exports this year and in 2007 to sustain the economy's current pace of expansion.
The more competitive value of the dollar turned around the trade deficit.
After all, an overvalued dollar gives us the ability to buy foreign goods at lower prices. And the existing volume of exports brings more yen and euros than they would if the dollar were more competitive.
