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.
Furthermore, children who experienced the high levels of externalizing behaviors were the ones who were most likely to experience mental disorders in adulthood. That is, the more externalizing behaviors a child displays, the more likely they are to have mental health problems in adulthood.hildren who display externalizing behaviors have a greater risk of being bullied and rejected by their peers than children who do not engage in externalizing behaviors. They are also more likely to have academic problems, engage in sexual risk-taking behaviors, and use drugs as adolescents.
