• There is evidence on the endogeneity of labor productivity to the wage and the persistence of wage inequality across similar workers and firms. • We build an evolutionary micro-dynamic model having these two features of the labor market as interconnected. • We explore the implications of such micro-dynamics for the macro-dynamics of the distribution of income, capacity utilization and output growth. • Firms periodically revise (and possibly switch) their choice of remuneration with a higher or lower wage. • The productivity differential across workers is endogenous to the distribution of wage strategies across firms. • The long run features wage inequality as a persistent outcome. • Plausibly low levels of wage inequality cause the micro- and macro-dynamic variables to experience self-sustaining cyclical fluctuations. There is extensive evidence on both the endogeneity of labor productivity to the wage remuneration and the persistence of wage inequality across observationally similar workers and firms. The paper builds an evolutionary micro-dynamic model having these two features of the labor market as interconnected, and explores the ensuing implications for the macro-dynamics of the distribution of income, capacity utilization and output growth. Firms periodically revise (and possibly switch) their choice of remunerating workers with a higher or lower wage, and the resulting labor productivity differential across workers is endogenous to the distribution of wage remuneration strategies across firms. The long run features wage inequality as a persistent outcome. Plausibly low levels of wage inequality cause the distribution of wage remuneration strategies across firms, and therefore the functional distribution of income, capacity utilization and output growth, all to experience self-sustaining cyclical fluctuations. Interestingly, the level of wage inequality is a bifurcation dimension. [ABSTRACT FROM AUTHOR]
