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.

INFORMATION SEARCH The decision to seek out or produce information based on a comparison of the cost of acquiring the information and the benefit obtained from the information. Efficient information search is achieved with a equality between the marginal cost of search and the marginal benefit of search. Because the marginal cost of search is invariably greater than zero, search effort stops short of acquiring complete information.
