Using an estimated DSGE model that features monetary and fiscal policy interactions and allows for equilibrium indeterminacy, we find that a passive monetary and passive fiscal policy regime prevailed in the pre-Volcker period while an active monetary and passive fiscal policy regime prevailed post-Volcker. Since both monetary and fiscal policies were passive pre-Volcker, there was equilibrium ...

We examine linear-quadratic (LQ) approximation of stochastic dynamic optimization problems in macroeconomics (and elsewhere), in particular in policy analysis using Dynamic Stochastic General Equilibrium (DSGE) models. We first examine the approximation to a general dynamic programming problem, which can be obtained via the Hamiltonian of the problem. We then define the problem that is solved b...

The purpose of this paper is to evaluate the recent developments in the theory and practice of monetary policy, drawing on the work of influential monetary economists of the past. JEL Classification: E5, E52

I develop an asset-pricing model in which financial assets are valued for their liquidity– the extent to which they are useful in facilitating exchange–as well as for being claims to streams of consumption goods. The implications for average asset returns, the equitypremium puzzle, and the risk-free rate puzzle, are explored both analytically and quantitatively in a version of the model that ne...

We estimate the dynamic stochastic general equilibrium model of Christiano, Eichenbaum, and Evans (2005) on United Kingdom data. Our estimates suggest that price stickiness is a more important source of nominal rigidity in the U.K. than wage stickiness. Our estimates of parameters governing investment behavior are only well behaved when post-1979 observations are included, which reflects govern...

Central bankers’ conventional wisdom suggests that nominal interest rates should be raised to implement a lower inflation target. In contrast, I show that the standard New Keynesian monetary model predicts that nominal interest rates should be decreased to attain this goal. Real interest rates, however, are virtually unchanged. These results also hold in recent vintages of New Keynesian models ...

In this paper, we develop and apply certain tools to evaluate the strengths and weaknesses of dynamic stochastic general equilibrium (DSGE) models. In particular, this paper makes three contributions: One, it argues the need for such tools to evaluate the usefulness of the these models; two, it defines these tools which take the form of prior and particularly posterior predictive analysis and p...

We study the interaction between monetary and fiscal policies in a Ramsey-Sidrauski model augmented with environmental capital. Equilibrium solutions are studied through “Green Golden Rule”. Despite non-separability of money utility intertemporally non-separable preferences, is environmentally neutral. Policy impacts environment via marginal rate transformation rather than substitution consumpt...

This paper presents a general approximation method for characterizing timevarying equilibrium portfolios in a two-country dynamic general equilibrium model. The method can be easily adapted to most dynamic general equilibrium models, it applies to environments in which markets are complete or incomplete, and it can be used for models of any dimension. Moreover, the approximation provides simple...

We build a new empirical model to estimate the global impact of an increase in volatility US monetary policy shocks. Specifically, we admit time-varying variances local structural shocks from stochastic specification. By allowing for rich dynamic interaction between endogenous variables and setting, find that interest rate uncertainty not only drives output inflation volatility, but also causes...
