The happiness which forms the utilitarian standard of what is right in conduct, is not...(one's) own happiness, but that of all concerned. As between his own happiness and that of others, utilitarianism requires him to be as strictly impartial as a disinterested and benevolent spectator.
There are various types of cost curves, all related to each other, including total and average cost curves, and marginal (for each additional unit) cost curves, which are equal to the differential of the total cost curves. At a level of Q at which the MC curve is above the average total cost or average variable cost curve, the latter curve is rising. 2  If MC is below average total cost or average variable cost, then the latter curve is falling.
Economists often talk of âdemand curvesâ and âsupply curves.â A demand curve traces the quantity of a good that consumers will buy at various prices. As the price rises, the number of units demanded declines.
