Specifically stated. For example, if there are conditions tied to one’s income which state that nothing can be spent on travel, that is an explicit limitation. If there are no conditions, but the income will not permit both a vacation trip and painting the house, the necessity for choice (or establishing priorities) is implicit; it goes “naturally” with the idea of limited funds. In financing medical and hospital care, limited funds require choices as to how to spend them. In the past, the rationing of funds has been implicit, but some states are beginning to use explicit methods.
