J.M. Keynes and F.A. Hayek had different economic ideas even though both were subjectivists seriously engaged with issues of time and uncertainty in economics. The source of the difference between their economic ideas was the difference between their philosophical ideas. Keynes was a Cartesian rationalist and justificationist; Hayek a critical rationalist and non-justificationist. We draw on Keynes's "A Treatise on Probability," Hayek's "The Sensory Order," and other works to defend our argument. Although Keynes and Hayek might both be called "subjectivists," there are varieties of subjectivism. Their subjectivist ideas are not fully compatible with one another and conduce to different theories of the market process. Hayek's theory, not Keynes's, allows us to say when markets will behave in the way Keynes described and when they will instead behave in more coordinated ways. In this sense, a Hayekian theory is needed to understand a Keynesian world.
EconWPA began as a conversation between Bob Parks and Larry Blume on January 28, 1993. I located Paul Ginsparg's archive (then xxx.lanl.gov) and he graciously installed his software on a Sun Sparc system which was supporting the department of economics email and computation. EconWPA began accepting papers July 1, 1993 and had ftp, email, gopher and web interfaces. The web interface for submissions was engineered into existence in July 1995. A complete and catastrophic machine failure in 1999 caused the loss of EconWPA's email new paper announcment service at which time there were over 15,000 subscriptions with over 8,000 unique email addresses.

I was told that I could keep operating EconWPA (as well as many other services including rfe.wustl.edu, barnett.wustl.edu, and three RePEc servers) but I would receive no support (hardware, software, or anthing else) and (as had been the case) no compensation. At that point, given the apparent low valuation of my activities by the department, and university, it made no sense for me to continue operating EconWPA or other services.
Thanks to all who have supported EconWPA in the past.
