| Abstract: | Traditional cross-sectional research is unable to measure the degree of income mobility in an income distribution. Using longitudinal data and various income stability indices, this paper measures the level of permanent inequality (immobility) in Spain for the period 1985–92. Results indicate that the transitory component of inequality is large and the level of income mobility increases over time while income inequality decreases slightly. More stability is found at the top than at the bottom of the income distribution and the range of the registered movements is rather short. |
