Definition. An ethical philosophy in which the happiness of the greatest number of people in the society is considered the greatest good. According to this philosophy, an action is morally right if its consequences lead to happiness (absence of pain), and wrong if it ends in unhappiness (pain).
In an economic sense, a perishable good is one which, when used, is used up. Food is a good example, whether it is perishable in a biological sense or not. Canned food may last a hundred years, and there is honey unspoiled in the pyramids from thousands of years ago, but when you eat them, they are gone.
