Una spiegazione cognitivista degli effetti perversi delle scelte pubbliche.

Effetti di crowding-out e regolazione sociale

N. 200

Summary - A model of cognitive rationality and a cognitivistic methodology, used in the reconstruction of belief system which are behind human actions and human judgements, could be a useful tool in order to explain non intentional and undesirable effects originated from public choices. In particular this model allows us to better understanding why people, affected by change of institutional conditions and of social rules caused by an exogenous, purpose-directed intervention of public authority, radically change their state of mind. This concerns not only individual utilities related to alternatives of actions, but also frames used to categorised alternatives of actions and tacit knowledge about implicit social rules. This work will support this thesis on the base of empirical results found out in economic and psychological research and will exploit this thesis in order to justify, on empirical basis, the intrinsically limits of a social order created by public authority. Cognitive reationality would be a strong argument for a strong limitation of public power.
