Research on crisis management and natural disasters identifies three types of behaviour by companies in order to recover from a trauma, as Carlo Salvato, a professor of strategy at Bocconi, explains in this video: "There are those who go bankrupt and must therefore receive massive aid from governments; there are those who are resilient, that is, who come out of the crisis by returning to their starting positions also thanks to aid such as redundancy funds; finally, there are those who take advantage of the crisis to become more competitive with courageous investments in technology".
