Abstract This has been an unusually productive exchange. My critics largely accept my main theoretical claims about economic calculation and socialism. They have also started to do what advocates of the Misesian view should have been doing for decades: offer empirical evidence that that the calculation problem is serious. While I continue to believe that incentive problems explain most of the failures of socialism, I am slightly less confident than I was before. Fortunately, there are many unexploited sources of information (...) to help resolve the issue. (shrink)
