CHAPTER 9—PERFECT COMPETITION HOME WORK 1. Market structure is determined by the a. volume of discounts‚ the quantity of foreign exchange‚ and the effects of Federal Reserve policy b. influence of government policy‚ the number of qualified buyers‚ and the effect of generally accepted accounting principles c. number of buyers and sellers‚ whether the product is standardized‚ whether there is free entry and exit‚ and how well informed the buyers and sellers are about the market d.

Treasury yield curve is obtained from the prices of Treasury strips. Strips are essentially zero-coupon bonds which are traded for a variety of maturities. From the strip prices‚ you can directly obtain the yield curve. The spot rates are what are used to discount the future cash flows of bonds. Any coupon bond can be engineered from a portfolio of zero-coupon bonds. The yield on a zero-coupon bond is called a spot rate; the yield curve that consists of spot rates is called the spot rate curve. 4

Teaching Notes Now we step back from supply and demand analysis to gain a deeper understanding of what lies behind the supply and demand curves. It will help students understand where the course is heading if you explain that this chapter builds the foundation for deriving demand curves in Chapter 4‚ and that you will do the same for supply curves later in the course (beginning in Chapter 6). It is important to explain that economists approach behavior somewhat differently than‚ say‚ psychologists

Kyungnam‚ 645-797‚ Republic of Korea a r t i c l e in fo abstract This paper proposes a new estimation method of total cost and average cost curves and applies it to the telecommunications industry. The method is more flexible and entails less hassle for data collection than traditional methods. The results show that the longrun average cost (LRAC) curve is downward sloping‚ revealing the presence of economies of scale in production. The two largest Korean mobile network operators are realizing

(Marginal Rate of Substitution) Slope of indifference curve= the amount of a product that must be substitute for another if utility is to remain unchanged. The ratio is the marginal rate of substitution. The MRS is the slope of the indifference curve at a certain point. I spend my money on the product that gave the most marginal utility. Ex: How much X do I have to give to get an extra unit of Y ? Example of indifference curves= If my MRS does not depend on

(Demand Under Perfect Competition) What type of demand curve does a perfectly competitive firm face Why The perfectly competitive firm faces a demand curve that is horizontal at the prevailing market price. This is the result of firms in the industry producing a commodity. No individual firm would want to raise its price above its competitors priceswhich

An oligopoly describes a market situation in which there are limited or few sellers. Each seller knows that the other seller or sellers will react to its changes in prices and also quantities. This can cause a type of chain reaction in a market situation. In the world market there are oligopolies in steel production‚ automobiles‚ semi-conductor manufacturing‚ cigarettes‚ cereals‚ and also in telecommunications. Often times oligopolistic industries supply a similar or identical product. These

1. Suppose there are 100 consumers with identical individual demand curves. When the price of a movie ticket is $8‚ the quantity demanded for each person is 5. When the price is $4‚ the quantity demanded for each person is 9. Assuming the law of demand holds‚ which of the following choices is the most likely quantity demanded in the market when the price is $6? Explain and show calculations‚ While the question asks of the choices given what the quantity demanded will be‚ there are no choices

Criticisms for “The Bell Curve” As the book breeches many controversial subjects about race and intelligence‚ there have been many people who have said that the findings in Herrnstein and Murray’s joint publication are not only filled with bias‚ but also fail to represent common testing errors that may leave the minority at a disadvantage. In an article entitled “Bias in mental testing since Bias in Mental Testing”‚ Robert Brown and his colleague Cecil Reynolds refute the use of cognitive assessment
