摘要：The current economic crisis requires fast information to predict economic
behavior early, which is difficult at times of structural changes. This paper
suggests an innovative new method of using data on internet activity for that
purpose. It demonstrates strong correlations between keyword searches and
unemployment rates using monthly German data and exhibits a strong potential for
the method used.
