If an additional competitor reduces output per firm in a homogenous Cournot-oligopoly, market entry will be excessive … the excessive entry prediction. Tax evasion raises the number of firms in market equilibrium and can alter their welfare …-maximizing number. In consequence, evasion can aggravate or mitigate excessive entry.
