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 a linear-quadratic...
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...
The unconditional expectation of social welfare is often used to assess alternative macroeconomic policy rules in applied quantitative research. It is shown that it is generally possible to derive a linear-quadratic problem that approximates the exact non-linear problem where the unconditional...
This paper explores the effect of time varying velocity in a transition to price stability. Nonstationary velocity, expressed as function of consumption, is made endogenous in Ireland's (1997) model. We find that the disinflationary booms found by Ball (1994) may or may not disappear; and also...
In this paper we study and quantify the e¤ects of a disinflationary policy on output and welfare. Our focus is the policy question of the optimal response to low inflation.The analysis takes place in the context of a DSGE model with sticky prices, time varying velocity and imperfect...
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...
We analyze business cycle implications of oil price uncertainty in an oil-importing small open economy, where oil is used for both consumption and production. In our framework, higher volatility in oil prices works through two main channels. On the one hand, it makes the marginal product of...
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 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...
