This study intends to measure the relationship between Brazilian economic welfare and income mobility. To achieve that it was used a model of intertemporal consumption proposed by Gottschalk e Spolaore (2002). This theoretical support allows to evaluate isolated the two sources of mobility: the reversibility and the source independence. The simulations suggest that flexibilizantion of Brazilian social structure, represented by an increase of income mobility, results a positive impact on the economic welfare.
