- I think these people are describing a sentiment that they sense in the libertarian movement, not an explicit set of works. (I consider myself one of the people working on post-austrian solutions.) There are a number of factors that are driving that sentiment.
- We are no longer battling socialism but redistributive democracy. The Austrian canon is not as suited to the current battle as it was to the previous battle.
- “Austrian” has been appropriated by the anarchists, as a means of claiming legitimacy, and this has been advocated by the Mises Institute in particular. And there is an attempt by the intellectual community to abandon the term ‘Austrian’ in order to distance itself from Rothbardian anarchism. I suspect that this is the reason you’re seeing the term float around.
That’s my suspicion. If you pointed me to a few examples I’m pretty sure I could directly address it. It’s not like there are all that many influential people in the movement.
