On Comparative-Static Analysis in Numerical Nonlinear Economic Models.

Many economic models can be formulated as a system of nonlinear equations and solved numerically using a black-box equation solver found in software packages such as EUREKA or MATHEMATICA. Unfortunately, black-box solvers can fail for several reasons and the messages displayed upon termination may not be very informative. In this paper we discuss a Jacobian-based solution method we devised for comparative static analysis of a model of parking in order to cope with computational difficulties encountered with black-box solvers. Our method worked well and should apply to a variety of computational economic (and non-economic) models. Citation Copyright 1995 by Kluwer Academic Publishers.
