Testing the CVAR in the fractional CVAR model

Johansen, Søren; Nielsen, Morten Ørregaard - 2017

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...

The cointegrated vector autoregressive model with general deterministic terms

Johansen, Søren; Nielsen, Morten Ørregaard - 2016

In the cointegrated vector autoregression (CVAR) literature, deterministic terms have until now been analyzed on a case-by-case, or as-needed basis. We give a comprehensive uni ed treatment of deterministic terms in the additive model Xt = γZt + Yt, where Zt belongs to a large class of...

The analysis of nonstationary time series using regression, correlation and cointegration

Johansen, Søren - In: Contemporary economics 6 (2012) 2, pp. 40-57

There are simple well-known conditions for the validity of regression and correlation as statistical tools. We analyse by examples the effect of nonstationarity on inference using these methods and compare them to model based inference using the cointegrated vector autoregressive model. Finally...

Optimal hedging with the Vector Autoregressive model

Gatarek, Lukasz; Johansen, Søren - 2014

with general cointegration rank. Our hedge is optimal in the sense of minimum variance portfolio. We consider a model that … correlation and cointegration parameters. For short holding periods the correlation impact is predominant. For long horizons, the … hedge ratio should overweight the cointegration parameters rather then short-run correlation information. In the innite …
