The welfare cost of random consumption fluctuations is known from De Santis (2007) to be increasing in the level of individual consumption risk in the economy. It is also known from Barillas et al. (2009) to increase if agents in the economy care about robustness to model misspecification. In...

The ability of monetary policy to influence the term structure of interest rates and the macroeconomy depends on the extent to which financial market participants prefer to hold bonds of different maturities. We microfound such preferred-habitat demand in a fully-specified dynamic stochastic...

This paper investigates the consequences of introducing endogenous price stickiness into a standard monetary policy model.We find that the modification reduces the optimal degree of inflation stabilization to which the central bank should commit.The reason is that less inflation stabilization...

In this paper we introduce identifying restrictions into a Markov-switching vector autoregression model.We define a separate set of impulse responses for each Markov regime to show how fundamental disturbances affect the variables in the model dependent on the regime.We go to illustrate the use...

In this paper, we examine the incentives for central bank activism and caution in a two-country open-economy model with uncertainty and learning.We find that the presence of a strategic interaction between the home and foreign central banks creates an additional motivation for caution in...

Disinflationary episodes are a valuable source of information for economic agents trying to learn about the economy. In this paper we are particularly interested in how policymakers can themselves learn by disinflating. The approach differs from the existing literature, which typically focuses...

In response to the Great Financial Crisis, the Federal Reserve and the Bank of England have adopted unconventional monetary policy instruments. We investigate if one of these, purchases of long-term government debt, could be a valuable addition to conventional short- term interest rate policy...

In this paper we examine the optimal level of central bank activism in a standard model of monetary policy with uncertainty, learning and strategic interactions. We calibrate the model using G7 data and find that the presence of strategic interactions between the central bank and private agents...

The assumption of asymmetric and incomplete information in a standard New Keynesian model creates strong incentives for monetary policy transparency. We assume that the central bank has better information about its objectives than the private sector, and that the private sector has better...

For a Markov decision problem in which unknown transition probabilities serve as hidden state variables, we study the quality of two approximations to the decision rule of a Bayesian who each period updates his subjective distribu- tion over the transition probabilities by Bayes' law. The first...
