We study oracle … properties of LASSO estimation of weakly sparse vector-autoregressive models with heavy tailed, weakly dependent innovations with … and strong (ff-) mixing sequences as particular examples. From a modeling perspective, it covers several multivariate …

We consider the fractional cointegrated vector autoregressive (CVAR) model of Johansen and Nielsen (2012a) and show that the test statistic for the ususal CVAR model is asymptotically chi-squared distributed. Because the usual CVAR model lies on the boundary of the parameter space for the...

We consider the fractional cointegrated vector autoregressive (CVAR) model of Johansen and Nielsen (2012a) and make two distinct contributions. First, in their con- sistency proof, Johansen and Nielsen (2012a) imposed moment conditions on the errors that depend on the parameter space, such that...
