Nonlocal Automated Comparative Static Analysis

The name of the journal "Computer Science in Economics and Management" was changed to "Computational Economics" This paper reviews work on the development of a program "Nasa" for the automated comparative static analysis of parameterized nonlinear systems over parameter intervals. "Nasa" incorporates a fast and efficient algorithm "Feed" for the automatic evaluation of higher-order partial derivatives, as well as an adaptive homotopy continuation algorithm for obtaining all required initial conditions. Applications are envisioned for fields such as economics where models tend to be complex and closed-form solutions are difficult to obtain.Annotated pointers to related work can be obtained at http://www.econ.iastate.edu/tesfatsi/nasahome.htm
