Standard panel unit root tests (PURTs) are not robust to breaks in innovation variances. Consequently, recent papers have proposed PURTs that are pivotal in the presence of volatility shifts. The applicability of these tests, however, has been restricted to cases where the data contains only an...

Structural vector autoregressive analysis aims to trace the contemporaneous linkages among (macroeconomic) variables back to underlying orthogonal structural shocks. In homoskedastic Gaussian models the identification of these linkages deserves external and typically notdata-based information....

This paper revisits the monetary policy asset price nexus employing a novel identification approach for structural VARs in a framework of non-Gaussian independent shocks. This allows us to remain "agnostic" about the contemporaneous relations between the variables. We provide empirical evidence...
