Farmer Mac is the GSE charged with creating a secondary market in loans backed by agricultural real estate. The Farm Credit Administration (FCA) has estimated a credit risk model for agricultural mortgages. This model is a key determinant of Farmer Mac’s risk based capital (RBC) requirement. This paper reviews both the structure of FCA’s credit risk model, and the data used by FCA’s contractors to estimate the model. Serious concerns are raised about both data quality and the econometric specification in use. Under Basle II, RBC models will proliferate. Assessing the validity of credit risk models will become increasingly important.
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.
