First, I will cite two numbers: 30 in 2001 and 2,200 in 2012. These are the numbers of economic papers that get a hit when doing an internet search with the keywords “quantitative easing (QE).” In 2001, the Bank introduced the world’s first-ever QE.
In academia, those within the field of economics did not have a particularly high interest in the QE at the time. It gradually attracted attention, however, and once the Federal Reserve (Fed) and the Bank of England (BOE) introduced their QE policies following the Lehman crisis, studies on QE increased dramatically.
