| Summary: | The writer reviews the GEOMODEL 3.1 computer package. The package allows the user to solve systems of equations that describe two- or three-sector closed or open economies, with or without taxes, variable labor supply, and interindustry transactions. In addition, it solves single- and multi-country models and finds numerical solutions to nonlinear economic models that can be used to illustrate principles of economics, including fundamental results of microeconomic theory, international trade, public finance, and welfare economics. In general, it is a reasonably easy package to use, although a more sophisticated user may prefer the explicit equation manipulation facilities available in a package such as GAMS.
