Stewart Clay Myers (born August 1, 1940) is the Robert C. Merton (1970) Professor of Financial Economics at the MIT Sloan School of Management. He is notable for his work on capital structure and innovations in capital budgeting and valuation, and has had a "remarkable influence" on both the theory and practice of corporate finance. Myers, in fact, coined the term "real option". He is the co-author with Richard A. Brealey and Franklin Allen of Principles of Corporate Finance, a widely used and cited business school textbook, now in its 11th edition. He is also the author of dozens of research articles.
