Pigouvian taxes are named after English economist Arthur Cecil Pigou (1877–1959), who also developed the concept of economic externalities. William Baumol was instrumental in framing Pigou's work in modern economics in 1972. [3]
Arthur Cecil Pigou (/ ˈ p iː ɡ uː /; 18 November 1877 – 7 March 1959) was an English economist. As a teacher and builder of the School of Economics at the University of Cambridge , he trained and influenced many Cambridge economists who went on to take chairs of economics around the world.
Related efforts to achieve socially optimal quantities of externalities have long been a focus of microeconomic research, most famously by Ronald Coase [1] and Arthur Pigou. [2] Externality problems persist despite past remedies, which makes newer approaches such as the efficient voter rule important.
Pigou developed the concept of externalities in 1920 through ‘The Economics of Welfare’. [5] Essentially, Pigou argued negative externalities (spillover) of an activity should incur an extra cost or tax while activities that produce a positive externalities (spillover) should be subsidized to further encourage this activity.
Arthur Pigou had previously developed the concept of economic externalities in a publication of 1920 [15] in which he proposed that what is now referred to as a Pigouvian tax equal to the negative externality should be used to bring the outcome within a market economy back to economic efficiency.

A.C. Pigou (1877-1959). One of the achievements for which the great English economist A.C. Pigou is known, was his work on the divergences between marginal private costs and marginal social costs (externalities). In his book, The Economics of Welfare (1932), Pigou describes how these divergences come about:
Influential theories have been the ability theory presented by Arthur Cecil Pigou [2] and the benefit theory developed by Erik Lindahl. [ 3 ] [ 4 ] There is a later version of the benefit theory known as the "voluntary exchange" theory .
In law and economics, the Coase theorem (/ ˈ k oʊ s /) describes the economic efficiency of an economic allocation or outcome in the presence of externalities.The theorem is significant because, if true, the conclusion is that it is possible for private individuals to make choices that can solve the problem of market externalities.
