James Alexander Mirrlees was a very important economist from Scotland.

He was born on July 5, 1936, in Minnigaff. He went to Douglas Ewart High School to learn. Later, he studied at the University of Edinburgh. He earned a degree in mathematics and natural philosophy in 1957. Then, he moved to Trinity College at Cambridge. He finished his PhD there in 1963. His thesis was about planning for a changing economy. As a student, he loved to debate ideas with others.

Mirrlees spent his life teaching students all over the world. He was a professor at Oxford University for many years. He also taught at the University of Cambridge. He visited many famous schools in the United States. These included MIT, Yale, and UC Berkeley. He even traveled to Australia to teach at the University of Melbourne. Later in life, he worked in Asia too. He was a professor in Hong Kong and Macau. In 2009, he helped start a new college in Hong Kong.

His work focused on how money and rules work together. He studied something called asymmetric information. This is when one person knows more than another. This idea is very important for taxes. He looked at how these facts affect how much people save. He also studied how to make tax rules fair for everyone. He worked with a man named William Vickrey on these ideas. Together, they helped create new ways to think about money. His methods are now the standard way to study this field.

Mirrlees did a lot of great work with other smart people. In 1971, he worked with Peter A. Diamond. They created the Diamond–Mirrlees efficiency theorem. This was a big step for economic theory. He also wrote many books and papers about growth and taxes. He led a big project called the Mirrlees Review. This project looked at the tax system in the United Kingdom. He even served on a council to advise the government in Scotland. He taught many students who became famous leaders themselves.

Because of his brilliant thinking, he won a huge honor. He received the Nobel Memorial Prize in Economic Sciences in 1996. He shared this prize with William Vickrey. In 1997, he was also made a knight. This is a special title given by the Queen. Mirrlees lived a long and busy life of learning. He passed away in Cambridge, England, on August 29, 2018. His ideas still help people understand how to build a fair world.
