MEDIDAS E DETERMINANTES DA MOBILIDADE DOS RENDIMENTOS DO TRABALHO NO BRASIL

This paper makes an analysis of the evolution of real earnings mobility for Brazilian workers from 1984 to 2001. The evolution of five real earnings mobility indicators is calculated using the Pesquisa Mensal de Emprego data set. The economic and demographic determinants of real earnings mobility in Brazil are estimated using the Fixed Effect Method to the mobility indicators calculated for sample cells. Among the economic variables, the real average earning, the real interest rate and the real minimum wage have a positive effect in earnings mobility; the inflation rate, when controlled by the other variables, has only distributive effects on earnings; the impact of the unemployment rate depends on the concept of mobility adopted. The importance of demographic variables becomes clear when we look at the econometric results. Men, usually, have more mobility than women, except for per capita directional changes in real earnings. Younger groups also have more directional mobility compared to older individuals, but have lower mobility caused by relative trades among them. Education level seems to contribute to diminish the earnings mobility for those that have more than fourteen years of education.
