CEIS Research Paper
Prior to the financial crisis mainstream monetary policy practice had become disconnected from money. We outline the basic rationale for this development using a simple model of money and credit in which we explore the conditions under which money matters directly for the conduct of policy. Then, drawing on Goodfriend and McCallums (2007) DSGE model, we examine the circumstances under which money becomes more closely linked to inflation. We fi nd that money matters when the variance of the supply of lending dominates productivity and the velocity of money demand. This is because amplifying the role of loans supply leads to an expansion in aggregate demand, via a compression of the external finance premium, which is inflationary. We consider a number of alternative monetary policy rules, and fi nd that a rule which exploits the joint information from money and the external fi nance premium performs best.
Keywords: money, DSGE, policy rules, external fi nance premium.
