<h3><u>How Do Pigovian Taxes Work?</u></h3>
Pigovian taxes, sometimes called Pigouvian taxes, are levied against private individuals or companies who engage in activities that have negative side effects on society. Costs associated with adverse side effects are those that are not accounted for in the product's market price. The selling of tobacco products puts a load on the public healthcare system and causes environmental pollution, among other side effects that have detrimental external impacts.
After English economist and early externality theorist Arthur Pigou, who made a substantial contribution, Pigovian taxes were given their name.

<h3><u>How Is a Pigovian Tax Calculated?</u></h3>
A Pigouvian tax is notoriously tricky to calculate correctly. The tax should, in theory, have a value that is exactly equal to the externality's net cost. As a result, for a particular level of production, the tax would be equal to the difference between the societal cost and the marginal private cost.
