Our analysis begins with simple idea that situation in labor market has considerable impact on salary level. We proceeded from this situation and earlier when claimed that the nominal salary is corrected at any divergence between actual and possible in outputs. Here I intend to develop this basic idea, having brought in it specification: level of output influences also change of a real, and not just nominal salary.
When unemployment is insignificant, it is hard for employers to involve new workers, and they try all possible means to hold the workers. In these conditions of a position of workers and labor unions at negotiations are rather strong. In such "rigid" labor market the real wage usually grows. But when unemployment rages, workers and labor unions appear in weakness position as firms easily find to themselves new workers. It is necessary to achieve increase in a salary with huge work, and workers can be compelled to agree even with decrease in the real wage.
