Tests for identification through heteroskedasticity in structural vector autoregressive analysis are developed for models with two volatility states where the time point of volatility change is known.

The tests are Wald type tests for which only the unrestricted model including the covariance matrices of the two volatility states have to be estimated. The residuals of the model are assumed to be from the class of elliptical distributions which includes Gaussian models. The asymptotic null distributions of the test statistics are derived and simulations are used to explore their small sample properties. Two empirical examples illustrate the usefulness of the tests in applied work

  • From January 2012 to December 2016, Helmut Lütkepohl was Dean of the DIW Berlin Graduate Center and Bundesbank Professor in the field of "Methods of Empirical Economics" at the Freie Universität Berlin. Before that, he was Professor of Econometrics at the European University Institute in Florence (2002-2011) and the Faculty of Economics at the Humboldt Universität zu Berlin (1992-2001), Professor of Statistics at the Christian-Albrechts-Universität Kiel (1987-1992) and the University of Hamburg (1985-1987) and Visiting Assistant Professor at the University of California, San Diego (1984/85).

    He has been on the editorial board of several scientific journals like Econometric Theory, Journal of Econometrics, Journal of Applied Econometrics, Macroeconomic Dynamics, Empirical Economics und Econometric Reviews and has published numerous papers in academic journals. He is the author, co-author and editor of many books, like “Handbook of Matrices“ (Wiley, 1996), “Applied Time Series Econometrics” (Cambridge University Press, 2004) und “New Introduction to Multiple Time Series Analysis” (Springer, 2005).
