Structural DSGE models are used for analyzing both policy and the sources of business cycles. Conclusions based on full structural models are, however, potentially affected by misspecification. A competing method is to use partially identified SVARs based on narrative shocks. This paper asks...

We examine the sources of macroeconomic fluctuations by estimating a variety of richly parameterized DSGE models within a unified framework that incorpo- rates regime switching both in shock variances and in the inflation target. We propose an efficient methodology for estimating...

We show that the effectiveness of redistribution policy is tied to how much inflation it generates, and thereby to monetary‐fiscal adjustments that ultimately finance the transfers. In the monetary regime, taxes increase to finance transfers while in the fiscal regime, inflation rises,...

We introduce Behavioral Learning Equilibria (BLE) into a multivariate linear framework and apply it to New Keynesian DSGE models. In a BLE, boundedly rational agents use simple, but optimal AR(1) forecasting rules whose parameters are consistent with the observed sample mean and autocorrelation...

The aim of this paper is to study the relationship between the intertemporal behavior of taxes and wealth distribution. The optimal-taxation literature has often concentrated on representative-agent models, in which it is optimal to smooth distortionary taxes. When tax liabilities are unevenly...

This paper examines a dynamic stochastic economy with a benevolent government that cannot commit to its future policies. I consider equilibria that are time-consistent and allow for history-dependent strategies. A new numerical algorithm is developed to solve for the set of equilibrium payoffs....

We use an analytically tractable heterogeneous‐agent (HANK) version of the standard New Keynesian model to show how the size of fiscal multipliers depends on (i) the distribution of factor incomes, and (ii) the source of nominal rigidities. With sticky prices but flexible wages, the standard...

We propose an empirical framework for analyzing the macroeconomic effects of quantitative easing (QE) and apply it to Japan. The framework is a regimeswitching structural vector autoregression in which the monetary policy regime, chosen by the central bank responding to economic conditions, is...

This paper determines conditions for the existence of a unique rational expectations equilibrium-determinacy-in a monetary policy switching economy. We depart from the existing literature by providing such conditions considering all bounded equilibria. We then apply these conditions to a new...

We study the relationship between monetary policy and long‐term rates in a structural, general equilibrium model estimated on both macro‐ and yield‐data from the United States. Regime shifts in the conditional variance of productivity shocks, or "uncertainty shocks," are a crucial driver...
