Mardi intime de la Chaire Hoover par Mathias Dewatripont et Jean Tirole (ULB)

Scholars and civil society have argued that competition erodes supplier morality. This paper establishes a robust irrelevance result, whereby intense market competition does not crowd out consequentialist ethics; it thereby issues a strong warning against the wholesale moral condemnation of markets and pro-competitive institutions. Intense competition, while not altering the behavior of profitable suppliers, however may reduce the standards of highly ethical suppliers or not-for-profits, raising the potential need to protect the latter in the marketplace.
