abstract today, debt stabilization in an uncertain environment is an important issue. in particular, the question how fiscal and monetary authorities should deal with this uncertainty is of much importance. especially for some developing countries such as iran, in which on average 60 percent of government revenues comes from oil, and consequently uncertainty about oil prices has a large effect ...

On Identification of Bayesian DSGE Models In recent years there has been increasing concern about the identification of parameters in dynamic stochastic general equilibrium (DSGE) models. Given the structure of DSGE models it may be difficult to determine whether a parameter is identified. For the researcher using Bayesian methods, a lack of identification may not be evident since the posterior...

This paper analyzes the effects of lower bound for interest rates on distributions inflation and rates. In a New Keynesian model with bound, two equilibria emerge: policy is mostly unconstrained in “target equilibrium,” whereas constrained “liquidity trap equilibrium.” Using options data inflation, we find forecast densities consistent target equilibrium no evidence favor liquidity equilibrium....

This paper compares the Calvo model with the Rotemberg model in a fully nonlinear dynamic new Keynesian framework with an occasionally binding zero lower bound (ZLB) on nominal interest rates. Although the two models are equivalent to a first-order approximation, they generate very different results regarding the policy functions and the government spending multiplier based on nonlinear solutio...

The authors construct three financial conditions indexes (FCIs) for Canada based on three approaches: an IS-curve-based model, generalized impulse-response functions, and factor analysis. Each approach is intended to address one or more criticisms of the monetary conditions index (MCI) and existing FCIs. To evaluate their three FCIs, the authors consider five performance criteria: the consisten...

The results suggest that in long run, more than one third all euroised countries central, eastern south-eastern Europe (CESEE) are linked shadow rate. ...

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...

This paper estimates a Structural Dynamic Factor Model on a panel of 102 US quarterly series. We model economic comovements by means of 5 underlying structural shocks (oil price, productivity, aggregate demand, monetary policy, and housing demand). The results of the benchmark model (impulse responses and variance decompositions) are in line with those predicted by economic theory and usually e...

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 considers the joint problem of model estimation and implementation of monetary policy in the face of uncertainty regarding the process of structural change in the economy. We model unobserved structural change through time variation in the natural rates of interest and unemployment. We show that certainty equivalent optimal policies perform poorly when there is model uncertainty abou...
