Interventions/Environmental Policy/Pigou: Although not originally developed on the basis of environmental problems, Pigou (1920) took the view early on that the market cannot be left to itself in the case of external effects. Rather - so the argumentation - sovereign interventions are required, that contribute to an internalisation of externalities according to polluters since only by means of such state interventions can private and social costs or benefits be covered with the aim of increasing the welfare of society as a whole. In order to prevent the misallocation of scarce (environmental) resources and thus a sub-optimal market supply of private goods, external costs or external income must be internalised by way of taxation (so-called Pigou taxes) or state subsidisation (Hansjürgens 1992, p. 28ff (1); Endres 2000, p. 94ff (2)).
Intervention/Externalities/CoaseVsPigou: Coase 1960 (3): in the case of (environmental) external effects, there are no "polluters" or "victims" per se. Rather, a reciprocal character of external effects is to be assumed, i.e. if environmental impacts are allowed there are disadvantaged people, if these are prevented, there are also disadvantaged people. The reason for this is that environmental problems contain rival claims to use of environmental goods, which can basically be corrected in two possible directions (Hartwig 1992, p. 140 ff.(4); Feess und Seeliger 2013, p. 141 ff.(5)).
Example: An improvement of injured parties leads to costs on the part of the polluters.
Solution/Coase: Coase theorem: if there are no transaction costs, there is no need for government intervention to internalise external effects, as in this case the market leads to an optimal solution of the environmental problem in the form of private negotiations between the parties concerned. (See Transaction Costs/Coase).
