Manganese Nodule Mining and Economic Rent

2020. 10. 13.  In the case of manganese nodules both kinds of barriers may exist. If commercially exploitable nodules are not a "free good" but are scarce, such scarcity could permit the creation of economic rent by miners. And if there exist barriers to entry into nodule mining, the conditions for increasing such economic rent would exist.
