نویسنده
چکیده
This note shows that oligopolistic loan competition with discriminatory pricing is inefficient when competing banks differ in their ability to screen borrowers: banks with better screening abilities win too small market shares. This result contrasts with a finding by Spence (1976) who showed that an oligopoly with price discrimination achieves first–best efficiency. JEL classification: D43; D82; G21
