One crucial lever for rebalancing this power asymmetry lies in scrutinising corporate mergers that would reduce labour market competition, just as regulators already do for product markets. Despite growing awareness of monopsony and labour market concentration, the European Union has taken remarkably little action. One promising approach would mirror existing product market protections: preventing mergers and acquisitions from creating excessive labour market power. Recent research reveals that mergers within already concentrated labour markets don’t just harm employees of the merging companies—they depress wages across entire local labour markets. Labour market dominance requires separate assessment from product market power, as the two don’t necessarily coincide.
