Inflation expectations, uncertainty, the Phillips curve, and monetary policy
As with many important theories, the long run value of Phillips curve theories may lie in the new flames that are emerging from its dying embers.

Methods for inference in large multiple-equation Markov-switching models
The inference for hidden Markov chain models in which the structure is a multiple-equation macroeconomic model raises a number of difficulties that are not as likely to appear in smaller models. One is likely to want to allow for many states in the Markov chain without allowing the number of free parameters in the transition matrix to grow as the square of the number of states but also without losing a convenient form for the posterior distribution of the transition matrix. Calculation of marginal data densities for assessing model fit is often difficult in high-dimensional models and seems ...

Bayesian methods for dynamic multivariate models
If multivariate dynamic models are to be used to guide decision-making, it is important that it be possible to provide probability assessments of their results. Bayesian VAR models in the existing literature have not commonly (in fact, not at all as far as we know) been presented with error bands around forecasts or policy projections based on the posterior distribution. In this paper we show that it is possible to introduce prior information in both reduced form and structural VAR models without introducing substantial new computational burdens. With our approach, identified VAR analysis of ...

Central Bank Solvency and Inflation
The monetary base in the United States, defined as currency plus bank reserves, grew from about $800 billion in 2008 to $2 trillion in 2012, and to roughly $4 trillion at the end of 2014 (see chart below). Some commentators have viewed this increase in the monetary base as a sure harbinger of inflation. For example, one economist wrote that this “unprecedented expansion of the money supply could make the ’70s look benign.” These predictions of inflation rest on the monetarist argument that nominal income is proportional to the money supply. The fact that the money supply has expanded ...

Are forecasting models usable for policy analysis?
In this article, Christopher A. Sims argues the answer to his title is yes. Sims explains that any decisionmaking model must incorporate some identifying assumptions to enable it to forecast the effects of alternative decisions. He argues that although all identifying assumptions in econometric policymaking models are of uncertain validity, those incorporated in vector autoregression (VAR) forecasting models have the advantage of allowing their uncertainty to be measured. Sims concludes by demonstrating a method for identifying a small macroeconomic VAR model so that it can be used to analyze ...

When does a central bank’s balance sheet require fiscal support?
Using a simple general equilibrium model, we argue that it would be appropriate for a central bank with a large balance sheet composed of long-duration nominal assets to have access to, and be willing to ask for, support for its balance sheet by the fiscal authority. Otherwise its ability to control inflation may be at risk. This need for balance sheet support?a within-government transaction?is distinct from the need for fiscal backing of inflation policy that arises even in models where the central bank?s balance sheet is merged with that of the rest of the government.
