Se critican dos tesis de Nancy Cartwright. Por un lado, se examina el enfoque de las “capacidades” en el campo de lo económico para argumentar que estas responden a la lógica de los “árboles de posibilidades” o resultados de final abierto; por el otro, se ofrece una alternativa al problema de “sobre-restricción” de los modelos económicos para mostrar cómo el gran número de supuestos auxiliares acota las posibilidades de extrapolar las conclusiones obtenidas en el modelo a condiciones distintas de las explicitadas en él. Se muestra la utilidad del análisis de robustez para descubrir las condiciones esenciales que cierran el árbol de posibilidades.
The article criticizes two of Nancy Cartwright’s theses. On the one hand, it examines the capabilities approach in the field of economics in order to argue that those capabilities function according to the logic of probability trees or open-ended results. On the other hand, it proposes an alternative to the problem of “over-restriction” of economic models, in order to show that the great number of auxiliary assumptions limits the possibilities of extrapolating the conclusions drawn from the model to conditions other than those it takes into account. The article shows the utility of robustness analysis in order to discover the essential conditions that surround the tree of probabilities.
