Résumé : This paper revisits Strulik’s model of growth with insecure property rights. In this model different social groups devote some effort to control a share of the capital stock. We show that a slight variation in the modeling of strategic interactions results in the coexistence of savings and efforts to control a share of the capital stock. We also study the effects of a change in the number of social groups, on growth. We also show that an increase in social fractionalization may lead to less effort devoted to control capital and to a higher growth rate.
