"This is the intriguing premise of a tool being used internally at BlackRock, the world’s largest fund manager, which it has nicknamed “the Yellen index”. It is a measure that suggests, on the economic indicators favoured by Ms Yellen, monetary tightening is already overdue and the Fed falls further behind the curve with every passing day."

This could be a really good additional exercise for the interest rate assignment: create a "Yellen Index".
