We propose an empirical procedure, which exploits the conditional heteroscedasticity of fundamental disturbances, to test the targeting and orthogonality restrictions imposed in the recent VAR literature to identify monetary policy shocks. Based on U.S. monthly data for the post-1982 period, we...

This paper assesses the plausibility of popular models of the monetary transmission mechanism for the G7 countries. For this purpose, flexible structural vector autoregressions are used to relaxe the restrictions behind the traditional identifying schemes of monetary-policy shocks and their...

This paper analyzes the important time variation in U.S. aggregate portfolio allocations. To do so, we first use flexible descriptions of preferences and investment opportunities to derive optimal decision rules that nest tactical, myopic, and strategic portfolio allocations. We then compare...
