Last decades show internationally a worsening 'trade-off' between inflation and unemployment, which phenomenon is called stagflation. A possible cause is the structure of taxes and premiums that OECD nations have in common. This common structure has a dynamic component: a tendency of reduction of both exemption and statutory marginal rates. The economic theory behind this policy and structure uses comparative statics and partial derivatives. The alternative dynamic analysis uses total derivatives, and thus takes account of tax parameter changes. In dynamics, the marginal rate relevant for incentives is close to the average tax rate. What is wrong about current policies, is that exemption is indexed on inflation while subsistence rises with inflation and real income. This causes either poverty or rising minimum wages, thus benefits, taxes, and lower incentives. If exemption was put at subsistence, then jobs could be created at the low end of the labour market, which saves benefits and reduces average taxes, which increases incentives. If low productivity labour has a stronger position in the labour market, then the risk of unemployment is spread more evenly, and trend-setting high productivity labour will be cautious about wage claims. Since the present situation is inefficient, an improvement is possible from which everybody can benefit (Pareto improving).
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.
