Abstract: Natural andman-made disasters are currently a source of major concern for contemporary societies. In order to understand their economic impacts, the inoperability input-output model has recently gained recognition among scholars. In a recent paper, Percoco (2006) has proposed an extension of the model to map the technologically most important sectors through so-called fields of influence. In the present note we aim to show that this importance measure also has a clear connection with local sensitivity analysis theory.
