The market-driven approach to correcting externalities is to  internalize  third party costs and benefits, for example, by requiring a polluter to repair any damage caused. But, in many cases internalizing costs or benefits is not feasible, especially if the true monetary values cannot be determined. negative externality (also called external cost or external diseconomy) is an economic activity that imposes a negative effect on an unrelated third party. It can arise either during the production or the consumption of a good or service.
This article is about the general case. For externalization of cost, in the context of economics, see externality. Externalization means to put something outside its original borders, especially to put a human function outside the human body. The opposite of externalization is internalization. In a concrete sense, by taking notes, we can externalize the function of memory which normally belongs in the brain.
