Next, the chapter compares various policy instruments the state can use to address market failures in dealing with externalities. Finally, the role of the financial system is discussed, which can counteract the current market failure in connection with externalities via sustainable measures in the area of investment and lending.enNegative externalities Invisible hand Market failure Marked-based instruments Border taxes Environmentalsocialand governance (ESG) factorsbook_section
