Controversy rages as to whether the recession in Germany in 2009 was caused by a slump in world trade or by a supply shock due to the problems in the banking sector.

However, the productivity shock can also be ex-plained by surplus capacity and declining investment activity. To this extent, therefore, it also reflects a demand shock, though, due to their structure, the DSGE models cannot adequately describe this.
