A new working paper by Daron Acemoglu, Alex He and Daniel le Maire, finds those with MBAs increase returns on assets in the five years after their appointment. But that is not because they boost sales, ratchet up investments or raise productivity. Rather, the higher returns are the result of suppressing workers’ wages.
MBAs managers seem to see workers as “costs to be reduced” rather than an investment in human capital.
