Tyler Cowen's silly book (see Reviews of "The Great Stagnation") led me to the idea that perhaps libertarianism has been stagnating.
The libertarian books that have made an impression on academia or political elites are rather few:
(1974) Anarchy, State, and Utopia
(1981) Free To Choose
(1957) Atlas Shrugged
(1985) Takings: Private Property and the Power of Eminent Domain
(1944) The Road to Serfdom
The most recent of those is 1985, 28 years ago. Since then there has been a welter of expositions, summaries and condensations on these subjects that strikes me as characteristic of groupthink, with no original syntheses that have impinged strongly on academia or political elites.
This is hardly true in liberalism, where at the very least we have Amartya Sen and Martha Nussbaum's Capability Approach.
I'm inclined to think my stagnation argument is even better than Tyler Cowen's. Can anybody think of any new facet of libertarianism making an impression on academia or political elites since 1985 at anywhere near the scale of the immediate impact of these previous writings?
