The use of long-run restrictions for the identification of technology shocks

We survey the recent empirical literature using long run restrictions to identify technology shocks. We provide an illustrative walkthrough of the long-run restricted vector autoregression (VAR) methodology in a bivariate framework. Additionally, we offer an alternative identification of technology shocks that can be imposed by restrictions on the long-run impulse responses. Our results from this methodology compare favorably to the empirical literature that uses structural VARs to identify technology.
