    Attractiveness Compensates for Low Status Background in the Prediction of Educational Attainment

    People who are perceived as good looking or as having a pleasant personality enjoy many advantages, including higher educational attainment. This study examines (1) whether associations between physical/personality attractiveness and educational attainment vary by parental socioeconomic resources and (2) whether parental socioeconomic resources predict these forms of attractiveness. Based on the theory of resource substitution with structural amplification, we hypothesized that both types of attractiveness would have a stronger association with educational attainment for people from disadvantaged backgrounds (resource substitution), but also that people from disadvantaged backgrounds would be less likely to be perceived as attractive (amplification)

    The two-matrix model can be solved by introducing bi-orthogonal polynomials. In the case the potentials in the measure are polynomials, finite sequences of bi-orthogonal polynomials (called "windows") satisfy polynomial ODEs as well as deformation equations (PDEs) and finite difference equations (Delta-E) which are all Frobenius compatible and define discrete and continuous isomonodromic deformations for the irregular ODE, as shown in previous works of ours. In the one matrix model an explicit and concise expression for the coefficients of these systems is known and it allows to relate the partition function with the isomonodromic tau-function of the overdetermined system. Here, we provide the generalization of those expressions to the case of bi-orthogonal polynomials, which enables us to compute the determinant of the fundamental solution of the overdetermined system of ODE+PDEs+Delta-E.Comment: 20 pages v1 18 Nov 2003; v2 9 Jan 2004: trivial Latex mistake correcte

    Personality and the reproduction of social class

    A burgeoning literature in psychology and economics examines how personality characteristics predict indicators of attained status. We build on this research by suggesting that connections between personality and attained status are also socially contingent: Valued personality characteristics are stronger predictors of attainments at lower levels of parent education (the resource substitution hypothesis), but such characteristics are less likely among the children of less educated parents (the structural amplification hypothesis). We examine these possibilities by drawing on the Mini-IPIP (a standardized instrument assessing personality), the National Longitudinal Study of Adolescent Health, and a statistical framework to test for moderated mediation. Results reveal that (1) personality characteristics have notable associations with educational attainment, hourly wages, and self-direction at work; (2) personality often has stronger associations with status attainments at lower levels of parent education; and (3) personality is a weak mediator of associations between parent education and attained status. That is, the children of less educated parents may benefit more from valued personality characteristics, but they are slightly less likely to possess such characteristics. These results are discussed in terms of new avenues for research into diverse forms of capital and status attainment
