John B. Taylor 
Getting Off Track 
How Government Actions and Interventions Caused, Prolonged, and Worsened the Financial Crisis

In this concise volume, leading economist John B. Taylor offers empirical research to explain what caused the current financial crisis, what prolonged it, and what dramatically worsened it more than a year after it began. The evidence he presents strongly suggests that specific government actions and interventions are largely to blame and that any future government interventions must be based on a clearly stated diagnosis of the problem and a rationale for the interventions.
