Assume that the risk-free rate is 6% and the market risk premium is 8%.
valkas [14]

Answer:

r or expected rate of return - market = 0.14 or 14%

r or expected rate of return - stock = 0.2120 or 21.20%

Explanation:

Using the CAPM, we can calculate the required/expected rate of return on a stock. This is the minimum return required by the investors to invest in a stock based on its systematic risk, the market's risk premium and the risk free rate.  

The formula for required rate of return under CAPM is,

r = rRF + Beta * rpM

Where,

  • rRF is the risk free rate
  • rpM is the market risk premium

Under CAPM, the assumption follows that the beta of the market is always equal to 1.

So, expected return on the stock market will be,

r or expected rate of return - market = 0.06 + 1 * 0.08

r or expected rate of return - market = 0.14 or 14%

The beta of the stock is given. We calculate the required rate of return on the stock to be,

r or expected rate of return - stock = 0.06 + 1.9 * 0.08

r or expected rate of return - stock = 0.2120 or 21.20%

<u>A) private-sector entrepreneurs can expropriate the profits generated by the efforts of private and public entities.</u>

Explanation:

  • As there exist four basic structures of the market economy in the form of perfect competition, imperfect competition, oligopoly, and monopoly.  
  • Thus without any legal system of trade in the market economy, the profits that are generated by the public and private sectors can be taken away by these entities as a large number of small firms tends to compete in the market against each other with there homogenous products.
  • Thus under such circumstances, the market economy would deprive all the profits made by the other forms in the market and put barriers to entry for others. Buyers thus will be deprived of the quality products.
