Sir James A. Mirrlees is a Scotsman who received the Nobel Prize in economics in 1996 for his research on economic incentives. He shared the Nobel Prize with Columbia University’s William Vickrey. His most significant contribution to the subject of economics was his ground-breaking research on optimal income taxation or a progressive taxation system that included incentives for earning. When he began his investigation, taxes were quite high and the economy was centrally controlled. He believed that the government should increase taxes on the wealthy and use the funds for the benefit of the poor. He also assumed that the tax rate has a direct effect on the motivation of individuals to work and earn more. He computed the greatest marginal tax rate that should be imposed to high-income categories based on these assumptions. The optimal tax rate that he determined was only 20 percent of income, not the 83 percent that was customary in Britain at the time. In addition, he came to the conclusion that everyone should be taxed at a flat rate of 20% for the greatest benefit of all wage earners. In addition, he assisted in the design of contracts that would offer the greatest incentives to company employees.
Youth and Early Life
James Alexander Mirrlees was born on July 5, 1936, in Minnigaff, Kirkcudbrightshire, South West Scotland, United Kingdom.

After skipping his first year of college, he enrolled at the University of Edinburgh in 1954 and majored in philosophy and mathematics. In 1957, he received his B.A. and M.A. in Mathematics and Natural Philosophy from the same university, where he also won the “Napier Medal.”
In 1957, he enrolled in Trinity College, Cambridge, and added economics to his list of major studies in an effort to assist the economies of underdeveloped nations.
Amartya Sen, an Indian economist, arranged for him to participate in an MIT study in India. In 1963, after returning to ‘Trinity College,’ he got his Ph.D.
