Further examples of the appearance of matrices (and the role they play) in the course of the economists’ education

The paper makes up the third part of the series of articles aimed at establishing the usefulness of matrices for the study of contemporary economic sciences. The series was initiated by the present author in his previous articles of the subject (Rybicki, 2010, 2012). The themes discussed in the present article concern two areas: (i) the surface description of the Markov-type, continuous time stochastic dynamics (with special emphasis placed on “Poisson dynamics” and on families of transition probability matrices and intensity matrices – finite or denumerable spaces of states); (ii) the second is devoted to showing the role of eigenvectors in modeling the economic dynamics.
