AbstractResponses to the IPPR Commission on Economic Justice

En éste trabajo se aplica la teoría de los signos de Juan Poinsot para la evaluación de un "buen modelo económico". Primero se define qué se considera un buen modelo, luego se presenta el marco conceptual de Poinsot y se presentan algunas ideas actuales acerca de modelos económicos. Luego se muestra cómo se pueden combinar las ideas de Poinsot y sobre los modelos. La conclusión es que un buen modelo señala posibles causas de los fenómenos bajo estudio las que han de verificarse empíricamente.

Economic models enjoy growing use and importance. An environment characterized by rapid change and the interplay of a host of variables prompts increased use of and reliance on models. For example, one might want to predict the effect of a change in interest rates on housing starts. On the other hand, a company might desire to predict demand levels for specific building products given reported housing starts. Others may have an interest in a better understanding of how humans behave in response to a change in variables in the environment. The first paper in a two paper series, provides a perspective and guidelines useful to the professional who may have to make decisions about economic models such as the usefulness of models, the important issues to consider when developing a model, the appropriateness of an existing model and interpretation of model output. Provides guidelines for the development and use of models.
