I very distinctly used the word "economists" not "economics".
As for economists who acknowledge her influence, one need only pay attention while reading articles at Mises.org and LewRockwell.com. DiLorenzo and Reisman come immediately to mind but there are many others. Even Rothbard was influenced by her, although not always in agreement with her. For that matter, von Mises paid her compliments.
Rand's major influence is the restoration of Aristotle's views into modern thinking and her own additions to metaphysics, epistemology and especially the moral foundations that underpin Austrian economics.
Because Schmidt emphasized thinkers in these realms, his omission of Rand is a glaring fault.
