QE and Unemployment : A Financial Friction DSGE Model with LSAPs and Labor Market Search

In response to the disruption of credit markets and the zero lower bound during the recent financial crisis, the Federal Reserve introduced a variety of new policy tools. Perhaps, the most visible of these tools is large scale asset purchases (LSAP) programs, often referred to as "quantitative easing" (QE).
