Bayesian Graphical Models for Structural Vector Autoregressive Processes

Abstract: Vector autoregressive models have widely been applied in macroeconomics and macroeconometrics to estimate economic relationships and to empirically assess theoretical hypothesis. To achieve the latter, we propose a Bayesian inference approach to analyze the dynamic interactions among macroeconomics variables in a graphical vector autoregressive model. The method decomposes the structural model into multivariate autoregressive and contemporaneous networks that can be represented in the form of a directed acycli… Show more

“…Methodologically, we build upon the Gaussian Graphical model for multi-variate systems proposed by Whittaker (1990), Dawid and Lauritzen (1993), Lauritzen (1996), , Wang and West (2009), Wang (2010), Rodriguez, Lenkoski, and Dobra (2011), Wang, Reeson, and Carvalho (2011) and Ahelegbey, Billio, and Casarin (2016). In particular Wang et al (2011) developed a dynamic matrixvariate graphical model which allows to capture conditional dependencies under a time-invariant graphs.…”

“…In particular, to estimate 4 This identi cation strategy builds on the previous works by by Swanson and Granger (1997); Bessler and Lee (2002); Demiralp and Hoover (2003); Moneta (2008). Recently also Bayesian strategies have been used to tackle the same issue (see Ahelegbey et al, 2016). 5 For more details about Independent Component Analysis, its assumptions, algorithms and related concepts see Hyvarinen et al (2001) and references therein.…”

“…Clearly, the WSBM approach is independent by the chosen methodology in the network estimation and alternative techniques such as graph-based approaches (i.e. Ahelegbey et al, 2016a) and sparse models (i.e. Ahelegbey et al, 2016c;Hautsch et al, 2015) can be applied.…”
