Frank Ramsey

Frank Ramsey published foundational papers in 1927 on optimal taxation, now known as the Ramsey rule, and optimal economic growth. His work on the Ramsey growth model laid the groundwork for modern macroeconomic theory. Despite his young age, his mathematical models fundamentally shaped how economists understand savings and government revenue.

Frank Plumpton Ramsey died in January 1930 at the age of 26 after suffering from severe jaundice and liver complications. Despite his incredibly brief career at the University of Cambridge, his academic output was massive. The exact medical cause of his death has historically been attributed to a severe hepatic illness.

The Ramsey pricing rule is an economic principle stating that to minimize deadweight loss, taxes should be levied inversely to the elasticity of demand for goods. This means goods with inelastic demand—where consumers will buy them regardless of price changes—should theoretically be taxed more heavily. It was originally formulated by Ramsey to solve how a government should optimally raise a specific amount of tax revenue.

Yes, they are the exact same person; his full name was Frank Plumpton Ramsey, and he worked simultaneously as a mathematician, philosopher, and economist. He famously translated Ludwig Wittgenstein's "Tractatus Logico-Philosophicus" into English. His diverse genius allowed him to make landmark discoveries across multiple distinct academic disciplines.
