The Intergenerational Mobility of Income: A Study Applied to the Spanish Case (2005–2011)

Intergenerational income mobility has attracted the interest of many economists for—among other reasons—its role as a mechanism for reducing inequalities and achieving equal opportunities. In this paper, we analyse the intergenerational mobility of income in Spain in the years 2005 and 2011, located at different phases of the economic cycle. We use proxy variables (the economic situation of the household during the adolescence of the informant and the educational level achieved by parents) to study intergenerational income mobility, because there are not extant surveys with income information from parents and their descendants when they are part of a different household. With these variables, we try to verify the existence and degree of mobility by analysing different methodologies. The results suggest the existence of mobility in the two studied years, although a trend towards a reduction in intergenerational mobility is confirmed, already detected by other authors.
