Labor market is a continuous mechanism of adjustment labor demand and supply. If the interaction between demand and supply is effective, businesses find employees for newly created or vacant jobs, and people find new (or their first) jobs and a source of income. If the job search fails, it means a loss in output for enterprises and a continued unemployment for the unemployed, which ultimately results in considerable aggregate economic and social costs. Hence, it is very important to ensure an effective search for jobs, which largely depends on adjustment the dynamics of vacant jobs and labor in Russia. However, even under the current rapid spread of information and its relative accessibility, the desired result is not always reachable. The task is even more complicated in a segmented labor market where employees objectively possess different professional and qualification qualities and characteristics, as well as vacancies, which may imply different requirements for the employee's qualification level and other characteristics.An outline of the model approach used. Previous investigations (see, e.g., [1,2]) have shown that an approach based on methods developed for describing biological populations of the "predator-prey" type is sufficiently effective for forecast analytical studies on adjustment labor demand and supply [3].A population and labor-resource mobility model, based on official statistical reports, is described in [1]. It combines studies of changes in the numbers of vacancies ( w ( t )) and potential employees ( u ( t )), i.e., the number of working-age individuals not engaged by the Russian economy. Here, potential employees reflect current labor supply, and vacancies, current labor demand. In turn, the number of employees characterizes the values of labor demand and supply met, which are identically equal.Assuming that there is neither interaction between potential employees and vacancies nor mobility of labor between the employment system and potential employees (or the balance of this mobility is zero), then the growths of potential employees ( du ( t )) and vacancies ( dw ( t )) during period dt will be proportional to u ( t ) and w ( t ), which are considered as continuously differentiable functions, and to the length of the time interval providing it is small. Thus, we obtain (1) where ε 0 and ε 1 are growth coefficients expressing the ratio of growths du / dt and dw / dt to u and w.Depending on the subject matter of research, these coefficients reflect different phenomena. At the macrolevel, the growth coefficient of potential employees ε 0 is determined by demographic processes (birth rate, mortality, and migration). The vacancy growth coefficient ε depends on trends in demand, as well on job creation and closure. (It is assumed that job reductions take place only after unsolicited dismissals, natural losses, and so on.)In reality, population and labor mobility, i.e., in this case, the interconnection between potential employees and vacancies, affects both indicators. This impact is reflected ...
