Hayek made his name at LSE and won a frickin' Nobel Prize.
Mises taught at Vienna and NYU (some small LAC, I guess).
You also conveniently neglected Schumpeter and basically every Chicago economist ever (Simons, Viner, Becker, Stigler, Lucas?). (By what definition, other than anarchist, is Friedman not a libertarian?)
In any case, the Austrians are irrelevant to the OP's question. He asked about pro-market, freshwater macro. Which basically means Chicago, monetarist, rational expectations macro.
If anything, the success of Chicago demonstrates the exact opposite of your point: If your academic rigor is the par of excellence, your political posiitions are irrelevant to your academic standing.
