Is Kirzner still alive? If so, why don’t we hear from him? Does he still write?
Kirzner is still alive, but I’m not sure if he still writes (he is 80 years old). I think Kirzner would be an excellent choice for a Nobel prize in economics, given the work he has done in reviving the topic of entrepreneurship. I just don’t think he has been “influential” enough (according to mainstream standards, that is) — not enough citations in mainstream publications.
Here is a lecture by him from just last year.
