The Pigou Club is an informal membership organization founded by macroeconomist Gregory Mankiw.


The Pigou Club is an informal membership organization that supports penalty taxes on certain consumption (known as Pigovian taxes after Arthur Cecil Pigou, a 20th century English economist who proposed them), especially conventional energy sources such as gasoline. Gregory Mankiw, a macroeconomist known for his work on New Keynesian economics and in the George W. Bush administration, is the Pigou Club’s creator. The Club, which exists as an informal membership organization, supports the levying of Pigovian Taxes. In a 2006 op-ed in the Wall Street Journal titled “Raise the Gas Tax,” which Mankiw on his blog describes as “The Pigou Club Manifesto,” Mankiw argues that legislators should gradually increase the tax on gasoline by $1 per gallon over the course of a decade. 1 In his defense of the increase, Mankiw cites environmental concerns as well as concerns about the costs of federal welfare programs, including Social Security and Medicare. 2

In March 2008, at a meeting of the Eastern Economic Association, Mankiw gave a talk on energy-related Pigovian Taxes. Later, the Eastern Economic Journal, a periodical of the association, published an edited version of the talk under the title “Smart Taxes: An Open Invitation to Join the Pigou Club.” In the article, Mankiw contends that a tax on carbon emissions is more economically efficient and attractive from a policy perspective than both regulations mandating more fuel-efficient equipment and cap-and-trade-systems. 3


Membership in the Pigou Club is informal; according to Mankiw’s description of the group, it consists of “economists and pundits with the good sense to have publicly advocated higher Pigovian taxes.” Members whom Mankiw recognizes on his blog are usually recognized as such after having publicly advocated for a Pigovian Tax (usually on energy) of some sort, usually in an op-ed, blog post, academic article, or television interview. Figures recognized by Mankiw include economist Bill Nordhaus, left-progressive New York Times columnists Thomas Friedman and Paul Krugman, environmentalist activist and former Vice President Al Gore, political commentator Andrew Sullivan, and economist Gary Becker. 4
