IMPERFECT COMPETITION: Any markets or industries that do not match the criteria for perfect competition. The key characteristics of perfect competition are: (1) a large number of small firms, (2) identical products sold by all firms, (3) freedom of entry into and exit out of the industry, and (4) perfect knowledge of prices and technology. These four characteristics are essentially impossible to match in the real world.

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.
