“…Traditional explanations suggest that large employers: i) hire more qualified workers, ii) compensate workers for bad working conditions, iii) have more market power and share their excess profits with their workers, iv) avoid or mimic unionisation, and v) substitute high monitoring costs with wage premia.

As a result, alternative hypotheses have been recently developed.…”
