Dear all, The next seminar in our series of statistics talks for people interested in quantitative methods in biology and medicine will take place on Thursday 22 September 2016 at 11h00, in the Salle Delachaux (Biopôle 2, first floor, Route de la Corniche 10, 1010 Lausanne, M2: Vennes). The speaker will be Dr. Qing Li from the University of Sherbrooke, Canada. Title: Disentangling causal effect of socio-economic status on health for aged Quebeckers Abstract: While the socio-economic status-health gradient is well-known, it is more difficult to estimate causality. Using data of Quebeckers aged 67+, we model observed income as a sum of time-invariant permanent income and other components that vary with time, and estimate causal effect of permanent income (and other exogenous covariates) on four health dimensions namely physiology, chronic disease, depression and cognition. We find that permanent income have the strongest effect on cognition and the effect is stronger for the low income group. The causality from permanent income to health exists in other health dimensions though it is not as strong as in the cognition dimension. The causality from health to observed income is not statistically significant in general. We compare our results with a model where individual fixed effect is eliminated with a differencing approach; the results support our modeling of time-invariant permanent income for aged people. This seminar is organized in collaboration with the platform "Economie de la Santé" and the seminar « Health and Labour Economics » from the Faculty of Business and Economics, University of Lausanne. Hope to see you there!
