South Africa is one of the most unequal nations in the world. This revenue inequality is principally attributable to high unemployment and enormous variations in wages.
In South Africa right this moment, economists and policy-makers usually give attention to employee traits resembling schooling to deal with wage inequality. Elsewhere, nevertheless, consideration has not too long ago returned to the energy that bosses must set the wages of employees.
In my study, I doc that employer wage-setting explains over a 3rd of wage inequality in South Africa. In truth, for many employees, particular employers clarify about half of the variations in pay.
Employers get this energy to set wages from a mix of two issues. One is the giant variations in productiveness between employers. The different is the lack of competitors – between bosses – for employees, which is possible associated to high unemployment. Both elements are notably extreme in South Africa.
As my paper reveals, South Africa’s world-leading wage inequality has as a lot to do with what bosses are doing because it does with how educated or skilled employees are.
Job hopping
A problem for the paper was to isolate the part of the wage that’s attributable to employers, and never attributable to employee traits resembling schooling or expertise.
One method to do that is to see how a employee’s wage adjustments after they transfer from one employer to a different. These wage adjustments can’t be about productiveness or abilities – it’s the similar individual being paid a distinct wage relying solely on the place they work.
Have you ever moved jobs and acquired a wage bump, though you are doing roughly the similar work? Economists name this an employer wage premium. Using tax information from 2011 to 2016, I tracked practically all formal sector job movers in South Africa to estimate this premium for each employer.
In a aggressive labour market the place bosses should not have the energy to set wages, a employee ought to be paid equally regardless of the place they go, and there ought to be no employer wage premium.
Yet, Figure 1 reveals that wage bumps – and drops – after transferring jobs will be monumental. A employee fortunate sufficient to maneuver from a low-wage to high-wage employer greater than doubles their wage (mild pink line). The reverse can also occur: a employee at a high-wage job could also be compelled to maneuver to a low-wage employer, and receives a commission a lot much less (mild blue line).

These variations between low- and high-wage employers drive up wage inequality. Altogether, I estimate that employers account for 36% of wage inequality in the formal sector.
Accounting for different sources of inequality (for instance, the undeniable fact that some individuals have jobs and others don’t), employer wage premiums account for roughly one fifth of general revenue inequality in South Africa right this moment.
The boss is an enormous issue
Much of the dialogue on inequality in South Africa is about entry to high high quality schooling. This is essential.
But my analysis reveals that a big part of inequality is additionally attributable to which particular employer you land at.
In Figure 2, the distinction in complete wages for all besides the highest paid employees is as a lot defined by variations in particular employers (pink) as variations attributable to employee traits (blue). The upshot is that giant components of employees’ wages have little to do with schooling.
Such variations in wages attributable to the particular employer are discovered in many different nations too. But South Africa stands out for simply how a lot inequality employers account for, at the least in comparison with estimates for richer nations.

Why do bosses enhance wage inequality a lot?
The main financial fashions explaining variations in wages attributable to particular employers give attention to employer productiveness dispersion and monopsony energy. Monopsony energy is when bosses face little competitors from different bosses for the labour they make use of.
The quantity of cash you make for an employer, or income productiveness, relies on many issues that are particular to that employer. For instance, they might have higher know-how or have a well-liked model. Employers with increased productiveness usually pay employees extra, and so greater variations in income productiveness throughout employers induce larger wage inequality.
This dispersion in income productiveness is giant in South Africa in comparison with estimates for richer nations, however is just like different growing nations like India and China.
However, such income productiveness dispersion solely issues for wage inequality insofar as employers have monopsony energy. Without some monopsony energy, employees would simply stop to the highest paying employer. Indeed, one technique to measure this energy is to see how a lot employers can decrease wages with out employees quitting.
My estimates recommend that there is extra monopsony energy in South Africa than different locations. Bosses pay employees a smaller portion of what is produced, thereby contributing extra to the high wage inequality in South Africa. This additionally means employees face the next charge of exploitation.
This high employer monopsony energy could also be attributable to South Africa’s high unemployment. When unemployment is high, it is tougher to discover a job, and so employees are extra reluctant to stop in response to an employer wage lower. This has lengthy been popularly understood in phrases of the Marxian “reserve army of labour”. Thus employers doubtlessly hyperlink two of the nation’s most devastating options: inequality and unemployment.
Implications for coverage
Policy prescriptions to cut back employer monopsony energy are difficult. Nevertheless, it ought to be clear that the contribution of employers to South Africa’s inequality disaster warrants consideration. There are doubtlessly giant advantages to wages, employment and even taxation.
My evaluation reinforces the must centre the energy of bosses over employees in financial evaluation.
