TIE-IN SALE: A type of sale in which consumers can buy one good only if they purchase another good as well. For example, if your grocery store sells you a bag of tea with the condition that you buy a pound of sugar, that would be a tie-in sale. Because they allow a monopoly to increase its profit over what it could make by selling the two goods separately at constant prices, tie-in sales can be used to price discriminate. However, it is important to realize that there are other reasons for tie-in sales other than price discrimination, such as to increase efficiency. For example, when we buy a car, it comes as a package of several goods (tires, engine, etc), which would be very difficult (and inefficient) for consumers to assemble if they were bought separately.

WORLD VIEW:

An aspect of a scientific theory that includes fundamental, and unverifiable, axioms, beliefs, and values about how the world works. One example of an unverifiable world view axiom is belief in the existence of a supreme, omnipotent, omniscience being--that is, God. Political philosophies, which are essential to economic theories and policies, are intertwined with alternative world views.
World view axioms are unverifiable because they are not directly testable against the real world. They contain concepts that are inherently immeasurable. As such, they must be accepted on faith. Believe or not.

Albert Einstein, for example gave insight into his world view by saying, "God does not play dice with the universe." While unprovable, Einstein believed that the universe operated by a set of natural laws--not by random chance. In his view, nature was not random, an event did not occur by chance, it was caused by something, it operated according to cause-and-effect laws of nature.

The components of a person's world view include religious belief, political view, cultural background, social upbringing, and overall philosophy of life. Key components of a world view usually include a notion of how and why the universe was created, the reason for humanity's existence, the proper role of government in the society and the economy, and the fundamental goodness or badness of humanity.

While the axioms and beliefs that comprise a world view are not directly testable with real world data, they are not totally free of scientific scrutiny. In fact, each time a hypothesis inspired by a theory is tested against the real world, all parts of the theory, including the world view, are tested indirectly. If a hypothesis does not agree with the real world, if it fails a test, then it opens up the possibility that any part of the theory is incorrect, including the previously verified principles or the unverified world view axioms and beliefs.

The process of scientific discovery has continually called into question many of society's basic beliefs. Some axioms are supported, others are contradicted. Some beliefs are discarded, others survive.
