Lesson 3: Scarcity | Unit 4: College Cost

An example of the opportunity cost of attending college.- Tuition, fees, textbooks, sliderule, etc. ($932.71 per semester) is an explicit opportunity cost.
- The opportunity cost is all other things that you could have bought with this money-fuzzy dice, hot fudge sundaes, a used Ford Pinto, music CDs.
- The tuition cost of your college degree is the added up over all semesters ($7,461,68).
However, the TOTAL COST actually goes well beyond this explicit $7,461,68 payment, since there are other costs that don't involve a money payment:- By attending school you have foregone alternative activities like working.
- Unearned income, $15,000 per year, $60,000 for four years, is an extremely important implicit opportunity cost of a college education.
- Implicit opportunity costs need not have a dollar value attached.
- The foregone satisfaction from activities like watching television or sleeping, are also implicit opportunity costs.

OLIGOPOLY, BEHAVIOR Oligopolistic industries share several behavioral tendencies, including: (1) interdependence, (2) rigid prices, (3) nonprice competition, (4) mergers, and (5) collusion. In other words, each oligopolistic firm keeps a close eye on the decisions made by other firms in the industry (interdependence), are reluctant to change prices (rigid prices), but instead try to attract customers from the competition using incentives other than prices (nonprice competition), and when they get tired of competing with their competitors they are inclined to cooperate formally and legally (mergers) or informally and illegally (collusion).
