Utility is an economic term referring to the satisfaction received from consuming a good or service. Producers use estimates of economic value to set prices for their products taking into consideration tangible and intangible factors such as brand name. But that's not the only thing money does. The value function of an optimization problem gives the value attained by the objective function at a solution, while only depending on the parameters of the problem. x Relations and Functions - Hayden Economics "[2] To Keen and the tradition of David Ricardo, this corresponds to the classical concept of long-run cost-determined prices, what Adam Smith called "natural prices" and Karl Marx called "prices of production." [3] If the objective function represents some cost that is to be minimized, the value function can be interpreted as the cost to finish the optimal program, and is thus referred to as "cost-to-go function.
