In the context of global imbalances, several efforts have been made to estimate the magnitude of the dollar depreciation needed to reduce the U.S. trade deficit, which reached around 6 percent of gross domestic product (GDP) in the year preceding the 2008 financial crisis.[1] However, it’s also important to take into account the role of demand because its fluctuations at home and abroad can offset relative price movements.

A positive bump to German output would increase output and exports among other European economies.
