This paper investigates the role of firm
characteristics in driving wage inequality and firm wage premia in the South
African labour market.
The Abowd, Kramarz, and Margolis (AKM) and
Kline, Saggio, and Sølvsten (KSS) regression-based decomposition methods are
applied to matched employer–employee administrative tax data for the period
2011–19. Additionally, the Theil index is used as a comparative tool for
estimating wage inequality, given that the variance of logarithms applied in
the regression-based decomposition methods has been established as an imprecise
measure of inequality.
The results show significantly high
dispersion in wages, as estimated by both the AKM and the KSS methods as well
as the Theil index, reaffirming the extent of high inequality in the country.
Worker and firm characteristics account for 35 per cent and 18 per cent of wage
dispersion, respectively, with a positive worker–firm covariance accounting for
11 per cent. Firm size, industry, profits, geographical location, and whether firms
are locally or foreign-owned are found to be important in driving firm wage
premia.
