Product Market Cooperation, Foreign Direct Investment and Consumer Welfare

Cooperation among rival firms raises serious skepticism among economists, policymakers, and legal experts, since it generally hurts consumers.

Under Bertrand competition with differentiated goods, increased cooperation may increase consumer surplus, and it may increase or decrease the domestic welfare by attracting FDI
