Dynamics of probabilistic labor markets: statistical physics perspective

Abstract

We introduce a toy probabilistic model to analyze job-matching processes in recent Japanese labor markets for university graduates by means of statistical physics. We show that the aggregation probability of each company is rewritten by means of non-linear map under several conditions. Mathematical treatment of the map enables us to discuss the condition on which the rankings of arbitrary two companies are reversed during the dynamics. The so-called `mismatch' between students and companies is discussed from both empirical and theoretical viewpoints.
