REALISM OF PERFECT COMPETITION: Perfect competition is an idealized market structure that does NOT exist in the real world. While some real world industries might come relatively close to a one or two of the four key characteristics of perfect competition, none matches all four sufficiently that we can declare a perfectly competitively industry. Some industries come close on the large number of small firms and the identical product characteristics. A few industries have relatively good, although not perfect, information about prices and technology. However, almost all industries fall far short of the perfect mobility characteristics.

Less Demand and Less Supply
|

|
Here we have demand decreasing (tastes change) and supply decreasing (number of sellers declines).- A decrease in demand causes a decrease in both price and quantity.
- A decrease supply causes price to increase and quantity to decrease.
- The combined effect is an obvious decrease in quantity but a questionable change in price.
- At the new equilibrium the price is indeterminant.
- If both demand and supply curve shift in the same direction, then quantity also changes in that direction, but price is indeterminant.

The near monies added to M2 to derive M3 include large denomination certificates of deposit, institutional money market mutual funds, repurchase agreements, and Eurodollars. M3 is one of three monetary aggregates tracked and reported by the Federal Reserve System. The other two are designated M1 and M2.
