IVAROLA, Leonardo. "Exporting" the knowledge of economic models. Ideas y Valores [online]. 2017, vol.66, n.163, pp.203-222. ISSN 0120-0062.  https://doi.org/10.15446/ideasyvalores.v66n163.50026.

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.
