Among social democrats, a handful of serious and informed scholars:
Labour Party activist and Oxford professor Raymond Plant is taking Hayek seriously in The Neo-Liberal State.
Economist Ted Burczak is taking Hayek seriously in Socialism After Hayek.
Who else?
John Gray is taking Hayek seriously in his book Hayek on Liberty. A more apt title would have been Hayek on Philosophy.
Vernon Smith is taking Hayek seriously in his book Rationality in Economics.
