This paper shows that under the King et al. (1991) approach [KPSW, 1991. Stochastic trends and economic fluctuations. American Economic Review 81, 819-840] to structural identification in VEC models, the structural shocks with transitory effects do not have a contemporaneous impact on the weakly exogenous variables. This result is used to establish the conditions under which the KPSW and Sims (1980) identification schemes [Macroeconomics and Reality. Econometrica 48, 1-48] are equivalent in a model of US consumption, investment and private output.
