Optimal Level of Wage Inequalities in Polish Regions and Economic Growth

Summary/Abstract: The paper looks at the problem of optimal level of wage disparities in regional terms. First, the concept of parabolic effect of income inequalities on economic growth is presented. Author shows wage inequalities measured by Lorenz concentration ratio in Polish regions (NUTS 2) in 2000–2010. Then he tries to evaluate the influence of that disparities on economic growth using econometric model. The analysis provides only partial confirmation of above relation. Optimal level of wage inequalities, in regional term, was reliably assessed only for 5 Polish regions (NUTS 2).
