Who Is Joseph Stiglitz?

Born in 1943, Joseph Stiglitz attended Amherst College before serving as a professor at many of America’s top research universities. He earned his doctoral degree from the Massachusetts Institute of Technology in 1967. He has served on the faculty of several Ivy League institutions.

Over the course of his career, he has also worked with the United States government and several NGOs. In the 1990s, he was part of the U.S. Council of Economic Advisors and later chief economist of the World Bank. In the 2010s, he took up a position with the International Economic Association as its president.

Joseph Stiglitz has often offered his positions on a variety of economic topics. Free trade, monopolies, and economic development are just a few areas in which he has publicly opined.


Over the course of his career, Joseph Stiglitz has earned many awards. Early in his career, he earned the John Bates Clark Medal for contributions by an economist under 40.

Age has not stopped him from acquiring more awards. 2001 saw him earn the Nobel Prize for his work in economics. In 2010, he received the Gerald Loeb Award for business journalism.

Joseph Stiglitz and Asymmetric Information

Much of Joseph Stiglitz’s work in economics has looked at cases where people have different amounts of information. Rational economic behavior requires good information.

Insurance serves as his prime case. In the insurance field, insurers have access to very little information compared to their customers. Encouraging customers to tell insurers their details allows both parties to make more informed and beneficial decisions.

Joseph Stiglitz and Monopolistic Competition

Stiglitz’s work on monopolistic competition looks at problems with the idea of perfect competition in a market. Under perfect competition, consumers will choose the best product for their needs. In practice, however, brands and firms in competition with one another can lead to imperfect decision-making.

A hypothetical firm with a perfect product could still lose in the market if brand awareness and advertising led to lower product knowledge. As a result, these types of competitive markets have barriers to entry. They may not be economically efficient.

A Titan of Economic Thought

Few economists of the 20th century have had as broad an impact as Joseph Stiglitz. Academics, politicians, and interested laypeople have all been exposed to Stiglitz’s ideas. His influence in government organizations means even those who aren’t familiar have felt the impact of his work.
