General-to-Specific Model Selection Procedures for Structural Vector Autoregressions

Krolzig, Hans-Martin - Department of Economics, Oxford University - 2003

Structural vector autoregressive (SVAR) models have emerged as a dominant research strategy in empirical macroeconomics, but suffer from the large number of parameters employed and the resulting estimation uncertainty associated with their impulse responses. In this paper we propose...
