Map of yucatan peninsula for If a social welfare function is assumed, Paretooptimality is a necessary yet not sufficient condition for its identification. The optimum optimorum is the best Pareto-optimal point. The distinction between local and global optima is crucial in analyzing social welfare functions, where the maximorum is the point of maximum social well-being at which it is no longer possible to reorganize an economy such that one individual is better off without simultaneously reducing another individual’s utility level. Efficiency, then, is not some unique point toward which society may direct its efforts. Rather, many efficient solutions (in production and distribution) are feasible, and each is different in resource allocation, commodity distribution, and the distribution of overall utility. Clearly, the challenge of finding an optimal economic organization for a society cannot be resolved by appeals to efficiency alone. This insight has become extremely important for public policy analysis. Map of yucatan peninsula 2016.
