We compare optimal and simple interest-rate rules. Our model features optimizing agents, monopolistic competition in both product and labor markets, and one-period nominal contracts (for wages alone or for both wages and prices) signed before shocks are known. Exact solutions ensure that we obtain correct welfare rankings. Optimal rules maximize the unconditional expected utility of the represe...

We examine optimal and other monetary policies in a linear-quadratic setup with a relatively general form of model uncertainty, so-called Markov jump-linear-quadratic systems extended to include forward-looking variables and unobservable “modes.” The form of model uncertainty our framework encompasses includes: simple i.i.d. model deviations; serially correlated model deviations; estimable regi...

The author explores the role that Taylor-type rules can play in monetary policy, given the degree of uncertainty in the economy. The optimal rule is derived from a simple infinite-horizon model of the monetary transmission mechanism, with only additive uncertainty. The author then examines how this rule ought to be modified when there is uncertainty about the parameters, the time lags, and the ...

The second round of large-scale asset purchases by the Federal Reserve—frequently referred to as QE2—included repeated purchases of Treasury inflation-protected securities (TIPS). To quantify the effect QE2 had on the functioning of the TIPS market and the related market for inflation swaps, we exploit the measure of combined liquidity premiums in TIPS yields and inflation swap rates derived by...

In perturbation analysis of nonlinear dynamic systems, the presence of a bifurcation implies that the first-order behavior of the economy cannot be characterized solely in terms of the first-order derivatives of the model equations. In this paper, we use two simple examples to illustrate how to detect the existence of a bifurcation. Following the general approach of Judd (1998), we then show ho...

This paper examines the role of the monetary instrument choice for local equilibrium determinacy under sticky prices and different fiscal policy regimes. Corresponding to Benhabib et al.’s (2001) results for interest rate feedback rules, the money growth rate should not rise by more than one for one with inflation when the primary surplus is raised with public debt. Under an exogenous primary s...

Since John Taylor’s (1993) seminal paper, a large literature has argued that active interest rate feedback rules, that is, rules that respond to increases in inflation with a more than one-for-one increase in the nominal interest rate, are stabilizing. In this paper, we argue that once the zero bound on nominal interest rates is taken into account, active interest-rate feedback rules can easily...

Article history: Received 23 February 2012 Received in revised form 18 October 2012 Accepted 18 October 2012 Available online 24 November 2012 This study estimates a dynamic latent factor model of the yield curve for Canada using a newly constructed data series on the term structure of constant-maturity, zero-coupon interest rates. The state-space representation of the model is used to assess t...

A key variable for the conduct of monetary policy is the natural rate of interest – the real interest rate consistent with output equaling potential and stable inflation. Economic theory implies that the natural rate of interest varies over time and depends on the trend growth rate of output. In this paper we apply the Kalman filter to jointly estimate the natural rate of interest, potential ou...

JEL Classification: J24, M12, Z13 We examine the role of peers, commanders, and travel on the later life outcomes of black slaves and freemen who fought in the Union Army. Because most of the black soldiers who served were illiterate farm workers, the war exposed them to a much broader world. In this sense, the Union Army can be viewed as a training program with heterogeneous treatment effects....
