Abstract

Nell’articolo si propone una visione della cooperazione pluralistica e multidimensionale. In particolare, si cerca di mostrare come, sotto determinate condizioni, forme meno incondizionali di cooperazione si possono combinare con forme piu` gratuite. Partendo dal Dilemma del Prigioniero, si analizza l’evoluzione della cooperazione in presenza di diverse strategie, non tutte basate sull’ipotesi di self-interest e di condizionalità, che rappresentano l’eterogeneità delle forme della cooperazione nella vita civile. Le dinamiche di cooperazione sono studiate attraverso l’utilizzo di giochi evolutivi, sia in un contesto one-shot, sia di giochi ripetuti. Uno dei risultati di rilievo del modello è che la cooperazione è favorita dall’eterogeneità delle strategie.
