Franco Modigliani e l’oligopolio

I met Franco Modigliani in 1948. We had common interests in three fields of economics - Keynes and unemployment, the relationship between monetary mechanisms and the real, forms of market and price formation, in two other fields, widely explored by Modigliani, the common interest was less - I am referring to the problems of saving and the life cycle. Was also common love for empirical tests and, on a different level, on civic engagement. Intellectually we met on the issue of price formation in an oligopoly, which can be seen, in its various forms, such as the shape of the market more frequently in the modern economy. Modigliani incorporated the formula of training and changes in prices in oligopoly in two econometric models, the first developed in the United States, the second in Italy. In recent years, Modigliani became the promoter of a "Manifesto against unemployment in the European Union", which collaborated in six European economists (I was among them) and then had the accession of a large number of economists from around the world. In the Manifesto play an important role the investment function, designed by Modigliani and me in different but complementary ways, and the pattern of changes in prices, given with reference to the problem of inflation.
