Open Source Economics Models

Mark Thoma at Economist's View is creating a repository for open source economics models.  The idea is to emulate open source software by releasing a beta model to the world and inviting others to improve it.   Mark has contributed a very nice paper on social insurance that could be expanded upon, Brad DeLong has contributed two beta models on finance topics, and I have contributed some very preliminary notes and a touch of Mathematica code on the implications of uncertainty about one's own tastes for savings decisions and other behavior (an interesting idea but one I have not had the technical skills to exploit).  The models can be found in the right hand column of Economist's View.
