William Sharpe, 1990 co-winner of the Nobel Prize in economics, is one of the founders of the modern theory of finance. His most famous work involves the development of the capital asset pricing model (CAPM), which is now one of the fundamental tools for understanding equilibrium risk–return relationships for different assets.
