We develop a simple and intuitive approach for analytically deriving unconditionally optimal (UO) policies, a topic of enduring interest in optimal monetary policy analysis. The approach can be employed to both general linear-quadratic problems and to the underlying non-linear environments. We...

We discuss the issue of time consistency of monetary policy. We develop a simple and intuitive procedure to derive analytically the unconditionally optimal (UO) policy in a general linear-quadratic set-up, a perspective stressed by Taylor (1979) and Whiteman (1986). We compare the UO perspective...

This paper establishes that one can generally obtain a purely quadratic approximation to the unconditional expectation of social welfare when the steady-state is distorted. A specific example is provided employing a canonical New Keynesian model. Unlike in the non-distorted steady state case,...

In this paper we study the impact of a temporary lack of credibility in a transition to price stability. We quantify the effects of a period of disinflation on temporary output losses, and the impact of the lack of credibility on the optimal speed on disinflation. We demonstrate that the...

In a New Keynesian macroeconomic model under credible commitment, price level targeting dominates inflation targeting. But with sufficient inflation aversion the inflation targeting central bank can produce quantitatively similar results to one targeting the price level. The current degree of...

We develop two variants of an open economy general equilibrium model employing Blanchard-Yaari life overlapping generations, which are shown to capture a number of important aspects of the UK economic cycle. We analyse the equilibrium stochastic processes of the model’s endogenous variables in...

Following Hall (1997) it is increasingly common to incorporate preference, as well as productivity, perturbations in calibrated general equilibrium models. We assess the performance of a small open economy stochastic growth model (based on the Blanchard-Yaari framework) under alternate driving...

The unconditional expectation of social welfare is often used to assess alternative macroeconomic policy rules in applied quantative research. It is shown that it is generally possible to derive a linear-quadratic problem that approximates the exact non-linear porblem where the unconditional...

The unconditional expectation of social welfare is often used to assess alternative macroeconomic policy rules in applied quantitative research. This paper provides a detailed analysis of such policies. It sets out the unconditionally optimal (UO) policy problem and derives an LQ version of that...
