Recent empirical work on the effects of minimum wages has called into question the conventional wisdom that minimum wages invariably reduce employment. We develop a model of \emph{monopsonistic competition} with \emph{free entry} to analyze the effects of minimum wages, and our predictions fit the empirical results closely. Under monopsonistic competition, we find that a rise in the minimum wage a) raises employment per firm, b) causes firm exit, c) may increase or reduce industry employment. Minimum wages increase welfare if they raise industry employment, but welfare effects are ambiguous if employment falls. Industry price and employment are inversely related if the product market is competitive. However, if firms have product market power, a minimum wage which raises industry employment can also increase prices.
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.
