The science of economics covers a vast terrain, as is clear from the history of Nobel awards in this area. Among the many fields that have been recognized are portfolio theory to reduce investment risk, the discovery of linear programming algorithms to solve complex allocation problems, econometric methods as a way of systematically understanding history and behavior, economic growth theory, and general-equilibrium theory as the modern interpretation of the invisible hand of Adam Smith.
