Joint Bayesian inference about impulse responses in VAR models
نویسندگان
چکیده
We derive the Bayes estimator of vectors structural VAR impulse responses under a range alternative loss functions. also discuss construction joint credible regions for as lowest posterior risk region same show that conventional response estimators such median function or mean are not in general vector obtained by stacking interest. illustrate pointwise may imply shapes incompatible with any possible parameterization underlying model. Moreover, quantile error bands valid measure estimation uncertainty about because they ignore mutual dependence responses. In practice, tend to understate substantially vector.

Inference for Structural Impulse Responses in SVAR-GARCH Models
Conditional heteroskedasticity can be exploited to identify the structural vector autoregressions (SVAR) but the implications for inference on structural impulse responses have not been investigated in detail yet. We consider the conditionally heteroskedastic SVAR-GARCH model and propose a bootstrap-based inference procedure on structural impulse responses. We compare the finite-sample properti...
متن کاملBayesian Inference for Spatial Beta Generalized Linear Mixed Models
In some applications, the response variable assumes values in the unit interval. The standard linear regression model is not appropriate for modelling this type of data because the normality assumption is not met. Alternatively, the beta regression model has been introduced to analyze such observations. A beta distribution represents a flexible density family on (0, 1) interval that covers symm...
متن کاملOn Bayesian inference about extinction.
Alroy (1) provides Bayesian estimates of the number of recent extinctions among reptiles and amphibians based on their sighting records. This involved calculating posterior extinction probabilities for individual species. This calculation is only cursorily described. The purpose of this comment is to provide an expression for this posterior probability and to raise two issues with the applicati...
متن کاملtitled “ Model - Free Impulse Responses ” August , 2003 Estimation and Inference of Impulse Responses by Local Projections
This paper introduces methods to compute impulse responses without specification and estimation of the underlying multivariate dynamic system. The central idea consists in estimating local projections at each period of interest rather than extrapolating into increasingly distant horizons from a given model, as it is done with vector autoregressions (VAR). The advantages of local projections are...
