Our current inflation stemmed from a fiscal shock. The Fed is slow to react. Why? Will the Fed's slow reaction spur more inflation? I write a simple model that encompasses the Fed's mild projections and its slow reaction, and traditional views that inflation will surge without swift rate rises....

In this essay, I analyze Salvador Allende's economic policies in Chile during the early 1970s. I argue that the explosion of inflation during his administration (above 1,500% on a six-month annualized measure) was predictable, and that the government's response to it, through massive and strict...

The fiscal theory states that inflation adjusts so that the real value of government debt equals the present value of real primary surpluses. Monetary policy remains important. The central bank can set an interest rate target, which determines the path of expected inflation, while news about the...

In standard solutions, the new-Keynesian model produces a deep recession with deflation in a liquidity trap. The model also makes unusual policy predictions: Useless government spending, technical regress, and capital destruction have large multipliers. These predictions become larger as prices...

In this paper I analyze the work on exchange rates and external imbalances by University of Chicago faculty members during the university's first hundred years, 1892-1992. Many people associate Chicago's views with Milton Friedman's advocacy for flexible exchange rates. But, of course, there was...

This paper develops an analytical framework for the analysis of targeting rules for monetary policy. We derive the optimal money supply rule and analyze the implications of other monetary rules including rules that target nominal GNP, the price level, the monetary growth rate and the...

This paper surveys the research in the past decade on imperfect information models of aggregate supply and the Phillips curve. This new work has emphasized that information is dispersed and disseminates slowly across a population of agents who strategically interact in their use of information....

This paper explores a model of wage adjustment based on the assumption that information disseminates slowly throughout the population of wage setters. This informational frictional yields interesting and plausible dynamics for employment and inflation in response to exogenous movements in...

Expansionary fiscal policies have increased significantly following the subprime crisis in 2007 and the COVID-19 crisis, leading to fiscal dominance concerns, where a growing share of monetary authorities may be forced to deviate from policy targets to accommodate fiscal policies. Meanwhile,...
