Answer: b. the four-firm concentration ratio to increase.

Explanation: The four-firm concentration ratio should increase when and competition shifts from monopoly to oligopoly. A ratio that exceeds 40 percent is an indication of oligopololistic competition while a ratio of less than 40 percent is an indication of monopolistic competition. Concentration ratios are used to show the extent of market control of the largest firms in the industry. When it is computed using the four largest firms in an industry, it measures the extent to which the four largest firms dominate the sales of a good.

An easy reference rule is that an oligopoly exists when the top four firms in the market account for more than 60% of total market sales in the industry.

Fill in the blanks: Stock prices fall if investors either expect _________ growth rates or require _________ returns.A. higher,
devlian [24]

Answer:

C. lower, higher

The reason for this is that when growth rates are lower investors will be willing to pay less for the stock is because low growth rate mean that the capital gains will be less as stock price is less likely to increase in the future and dividend growth is also less. Also  the DDM model D*(1+G)/1-R shows that mathematically a lower growth rate would mean lower stock price

Also Higher required returns mean that the investor requires higher returns to buy the stock, because he may view the stock as risky and requires higher returns for the risk he is taking or he may have a higher opportunity cost (for eg interest rates may be high) with other investments. Mathematically the DDM model D*(1+G)/R-G shows us that a higher R would mean lower stock price.
