Trend and Comparative Analysis of Inequality of Social Opportunity

This article sets out a new method for the analysis of inequality of social opportunity. The shortcomings of the previous concepts and measures attempting to assess the degree of openness of the mobility process independently of marginal effects are displayed. The suggested new approach refers to relative opportunity distributions of individuals according to their social origin. Starting from the premise that these distributions underlying the observed allocation of social positions are continuous, it is assumed that it is possible to compare them using straight lines. The various slopes of the lines represent inequality of social opportunity coefficients which permit trend and comparative analysis of the mobility process net results.
