Structural vector autoregressions : checking identifying long-run restrictions via heteroskedasticity
Lütkepohl, Helmut; Velinov, Anton - 2014
) analysis. Such restrictions are typically just-identifying but can be checked by utilizing changes in volatility. This paper … reviews and contrasts the volatility models that have been used for this purpose. Three main approaches have been used …, exogenously generated changes in the unconditional residual covariance matrix, changing volatility modelled by a Markov switching …

The transmission of German monetary policy in the pre-Euro period
Lütkepohl, Helmut; Wolters, Jürgen - 2001
A small macroeconomic model is constructed to study the transmission of the monetary policy conducted by the Deutsche Bundesbank (DBB) since the middle of the 1970s. For this purpose quarterly, seasonally unadjusted data for the period from 1975 to 1998 are used, that is, the period until the...

Structural vector autoregressions with nonnormal residuals
Lanne, Markku (contributor); Lütkepohl, Helmut (contributor) - 2006
In structural vector autoregressive (SVAR) models identifying restrictions for shocks and impulse responses are usually derived from economic theory or institutional constraints. Sometimes the restrictions are insufficient for identifying all shocks and impulse responses. In this paper it is...
