I am looking for users and developers interested in collaborating on an open source sovereign rating model project. If you don't agree with your country's credit rating, here is a chance to do something about it! A video describing this project is available at http://www.youtube.com/watch?v=71d3FXCqKtY and a journal article explaining the rationale can be found at http://econjwatch.org/articles/rating-government-bonds-can-we-raise-our-grad e. The tool is available at http://www.publicsectorcredit.org/pscf.html. Source is posted at http://www.github.com/joffemd/pscf. The tool uses a Monte Carlo simulation which includes calls to Boost's normal and Cauchy random number generators. There are many opportunities for improvement upon the initial version. Please contact me if interested. Regards, Marc Joffe Public Sector Credit Solutions marc@publicsectorcredit.org
