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.

INDUCED IMPORTS

Imports from the foreign sector that depend on domestic income or production (especially national income and gross domestic product). That is, changes in income induce changes in imports. Induced imports are measured by the marginal propensity to import (MPM) and are reflected by a positive slope of imports line. Induced imports are the reason for induced net exports, generating a negatively sloped net exports line. Autonomous net exports are due to a combination of autonomous exports and autonomous imports.
