Peter Ireland is the Murray and Monti Professor of Economics at Boston College, a research associate at the National Bureau of Economic Research, and a member of the Shadow Open Market Committee. He joins the show to discuss his experience as a student at the University of Chicago as well as the nuts and bolts of how the Federal Reserve sets out to achieve its short-, medium-, and long-term objectives. David and Peter also discuss the role of monetary aggregates in monetary policy. Economists largely don’t pay much attention to the traditional simple-sum measures of the money supply anymore, but Ireland argues that more complex measures of money, called Divisia indices, can teach us a lot about the stance of monetary policy.
