What Is Entrepreneurship?:

Kirzner's explanation of entrepreneurship should be recognized for what it is; an abstract metaphor to help explain why markets clear. His focus is on the abstract, aggregate effects of acts of alertness. The abstract "entrepreneurial opportunity" is Kirzner's unit of analysis. He does not take uncertainty into account.

A full understanding of Kirzner's entrepreneur raises considerable doubt as to whether those studying entrepreneurship in the real world should focus on Kirzner's conception or not. Those studying entrepreneurship should seriously consider the alternative explanations presented by the Austrian School: by economists such as Menger, Fetter, Mises and Rothbard. They make human action the unit of analysis, not abstract "opportunities."

FK state,

It is the real-world, flesh and blood entrepreneur, who not only bears uncertainty in his judgments about deploying the resources he owns and controls but is also alert, creative, and leader — and not some abstract, hypothetical discoverer — who is the "driving force of the market."

It is questionable whether Kirzner's conception helps us understand the real-world entrepreneur.
