The Depreciating Dollar: Economic Effects and Policy Response
This report discusses the trend of depreciation of the dollar since 2002. This raises concern among some in Congress and the public that the dollar's decline is a symptom of broader economic problems, such as a weak economic recovery, rising public debt, and a diminished standing in the global economy. However, a falling currency is not always a problem, but possibly an element of economic adjustments that are, on balance, beneficial to the economy.
