A graduated excise allows mores patial control of congestion and pollution. The cost of a detour to a scheaper gas station defines a gradient, and the integral gives an excise mountain with its top at the center of the metropolitan area. Consisntency implies that the mountain with the maximal gradient is a cone. There are differential effects of fuel efficiency, tank size, speed and (virtual) wage costs. An increase in fuel efficiency e.g. reduces the size of the maximal exxcise cone. Legislation and control would be required to prevent riding bombs and graduated smuggling.
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.
