In economic analysis, the principle of marginal analysis refers to: dividing large problems into smaller, more manageable ones. the result that the optimal quantity of an activity is that at which the net benefit of the representative, or marginal, individual is maximized. the notion that a group's problems can be effectively analyzed by focusing on only a small subsample of the group. the result that the optimal quantity of an activity is that at which marginal benefit is equal to marginal cost
