COMPETITION AMONG THE MANY: A market with so many buyers and sellers that none is able to influence the market price or quantity exchanged. This type of competition is the one most favored by economists (the other type is competition among the few). Compared to a three-person sprint, this is like a 10,000-entry road race. To win this race, I can't count on the other 9,999 coming up injured. To win, I may have to be the best I've ever been. I just might have to set a world record. This is the type of competition that brings out the best, most efficient use of resources.

Topic:
Doing The Numbers: Endpoint
|
|
|
- Our task is to calculated the price elasticity of demand using the endpoint formula. I am presenting the endpoint formula for reference.
endpoint
elasticity | = | (Q2 - Q1)
Q1 | ÷ | (P2 - P1)
P1 |
- Suppose the values for this formula are P1 = $2.49, Q1 = 5,447 unit of a given good (say Tacos), P2 = $1.99, Q2 = 6,608 units of Tacos
endpoint
elasticity | = | 0.21 ÷ - 0.20 | = | - 1.05 |
- This value - 1.05 indicates that the a one percent decline in the price of Tacos results in a 1.05 percent increase in quantity demanded.

MARGINAL COST OF SEARCH The incremental cost incurred by additional search effort is the marginal cost of search. Marginal cost of search, also termed marginal search cost, is comparable to marginal cost of short-run production analysis. Marginal cost of search increases with an increase in search effort and is represented by the marginal cost of search curve. This is one half of the efficient information search decision. The other is marginal benefit of search.

[What's This?]
Today, you are likely to spend a great deal of time flipping through mail order catalogs looking to buy either a genuine down-filled comforter or a 200-foot blue garden hose. Be on the lookout for high interest rates.
