Puzzles of Inflation, Money, and Debt: Applying the Fiscal Theory of the Price Level

Abstract

The fiscal theory of the price level (FTPL) provides an update and revision of monetary theory to address puzzles raised by the failure of both the new Keynesian theory (commonly used by central bankers) and neoclassical monetarism (in particular, the quantity theory of money as interpreted by Milton Friedman and Anna Schwartz)—puzzles such as the low inflation that followed the sustained expansionary monetary policies post-2008. We aim to summarize and explain the FTPL as developed by Eric Leeper, John Cochrane, and others.
