Two stochastic models of income mobility

Guided by two markov chains with tridiagonal transition matrices of distinct structure, dynamic inequality characteristics of an income propagation process are compared with the static characteristics of the corresponding stationary distribution, i.e. the result of the process. the two models reflect the concepts of proportionate effect and regression towards the mean, respectively. moreover the influence of small process parameter changes (persevering perturbations) on the stationarydistribution is studied.;
