In a basic economics class we refer to this as "allocative efficiency".
In Macroeconomics we identify it as a point anywhere on the Production Possibilities Frontier indicating a particular bundle of goods produced at its lowest cost (Productive Efficiency) and most desired by consumers
In Microeconomics we identify is at the point where the Price (P) equals the Marginal Cost (MC) of producing the last unit(s). The price consumers are willing and able to pay and amount that at least equals the cost of the productive resources used to produce that unit.
Any hoot, this can be part of a lesson in allocation of resources and to pose the question "Why the movement away from Wheat production to Corn and/or Soybean?"
