Miller had a very big idea about company money. Most people used to think a company needed a perfect mix of debt. Debt is money that a company borrows to grow. They thought this specific mix would lower their costs. Miller and his partner said this was not true. They believed the mix of debt did not matter much. This idea is known as the Modigliani-Miller theorem.

This big idea started in 1958. Miller worked with a man named Franco Modigliani. They worked together at the Carnegie Institute of Technology. This school is now called Carnegie Mellon University. They wrote a famous paper called "The Cost of Capital, Corporate Finance and the Theory of Investment." They used a special idea called "no arbitrage." This idea says that easy ways to make free money disappear quickly.

Miller was a very busy and successful man. He was born in Boston, Massachusetts, in 1923. He studied at Harvard University as a young man. He earned a Ph.D. from Johns Hopkins University in 1952. He taught at the University of Chicago for many years. In 1990, he won the Nobel Memorial Prize in Economic Sciences. He shared this prize with Harry Markowitz and William F. Sharpe.

Merton Howard Miller was a highly influential American economist. An economist is a professional who studies how money, resources, and markets function. Miller is most famous for his work in corporate finance. Corporate finance is the area of study focused on how companies manage their money. He changed the way experts think about how businesses use debt and equity. Equity represents ownership in a company, while debt is money borrowed from others. His theories provided a new foundation for modern financial science.

Miller’s most significant contribution is the Modigliani–Miller theorem. He co-authored this theorem in 1958 with his colleague Franco Modigliani. Before their work, most experts believed in a traditional view of finance. They thought a company could lower its cost of capital by finding a specific debt-to-equity ratio. This ratio is the balance between borrowed money and owner investment. Miller and Modigliani argued that this specific mix was actually irrelevant to a firm's value. Their paper was titled "The Cost of Capital, Corporate Finance and the Theory of Investment."

To prove their theory, they used a logical concept called "no arbitrage." Arbitrage is the practice of taking advantage of price differences in different markets. The "no arbitrage" argument suggests that if a way to make riskless money exists, it will disappear quickly. Traders would act on the opportunity until the chance to make free money was gone. Miller and Modigliani used this premise to show that debt structures do not change a firm's fundamental value. They suggested managers should focus on minimizing tax liability instead. They believed managers should maximize corporate net wealth and let the debt ratio happen naturally.

Merton Miller had a distinguished academic career. He was born in Boston, Massachusetts, to Sylvia and Joel Miller. He attended Harvard University as an undergraduate student. During World War II, he worked as an economist for the Treasury Department. He focused on tax research for the government during this time. He later earned a Ph.D. in economics from Johns Hopkins University in 1952. His first teaching job after his doctorate was as a Visiting Assistant Lecturer at the London School of Economics.

Miller spent much of his professional life at the University of Chicago. He joined the faculty of the Booth School of Business in 1961. He remained there until his retirement in 1993, though he continued teaching for several more years. His research was so impactful that it formed the basis of "Modigliani-Miller Financial Theory." He held several leadership roles in the field of economics. He was a fellow of the Econometric Society in 1975. He also served as the president of the American Finance Association in 1976.

In 1990, Miller received one of the highest honors in his field. He shared the Nobel Memorial Prize in Economic Sciences with Harry Markowitz and William F. Sharpe. This prize recognized his massive impact on economic thought. Beyond academia, Miller served as a public director for important financial institutions. He worked for the Chicago Board of Trade from 1983 to 1985. He also served on the Chicago Mercantile Exchange from 1990 until his death. He even used his expertise to address real-world financial controversies. In 1993, he wrote about trading losses at Metallgesellschaft in the Wall Street Journal.
