Sign restrictions and statistical identification under volatility breaks : simulation based evidence and an empirical application to monetary policy analysis ; conference paper
Herwartz, Helmut; Plödt, Martin - 2014
Apart from a priori assumptions on instantaneous or long run effects of structural shocks, sign restrictions have become a prominent means for structural vector autoregressive (SVAR) analysis. Moreover, second order heterogeneity of systems of times series can be fruitfully exploited for...
