  • $\begingroup$ Hi there, and welcome to Econ.SE. This question, as is, needs some more information given to the readers. An explanation and source/citation for what Sims' critique is would be appreciated, for starters. $\endgroup$ – Kitsune Cavalry Sep 3 '17 at 23:43

  • $\begingroup$ This question could be improved by included a quotation from the linked slides. The question posted on this site is meant to be permanent and outside links tend to die over time. $\endgroup$ – jmbejara Sep 4 '17 at 23:49
