Depict on a graph a perfectly competitive market with a negative externality. Utilise the graph to cleary highlight and discuss the problems associated with the negative externality.[hint: focus on the quantity difference between the market equilibrium and the socially desirable equilibrum] now consider what happens if the market consolidates and becomes a monopoly (there is no need to depict this on a graph). Do you think the obesity and diabetes will increase or decrease? [hint: focus on the quantity difference betweeen a monopoly and perfectly competitive market]

What is semi-strong-form EMH? What would you expect to see/not see if markets where semi-strong form efficient? In other words, can you think of market events that would serve as evidence that market is or isn’t semi-strong-form efficient?

Please answer fast I will rate for you sure....

Ceteris paribus, current financial market returns will increase as _____. Group of answer choices a. the uncertainty about the productivity of capital goods increases and people become more risk averse b. the uncertainty about the productivity of capital goods increases and people become less risk averse c. the uncertainty about the productivity of capital goods decreases and people become more risk averse d. the uncertainty about the productivity of capital goods decreases and people become less risk averse

(1) Why is the risk-free return independent of the state of the economy? Do T-bills promise a completely risk-free return? (2) Why are High Tech’s returns expected to move with the economy whereas Collections’ are expected to move counter to the economy? Calculate the expected rate of return on each alternative and fill in the row for in the table. You should recognize that basing a decision solely on expected returns is appropriate only for risk-neutral individuals. Because the beneficiaries of the trust, like virtually everyone, are risk averse, the riskiness of each alternative is an important aspect of the decision. One possible measure of risk is the standard deviation of returns. (1) Calculate this value for each alternative, and fill in the row for σ in the table. (2) What type of risk does the standard deviation measure? (3) Draw a graph that shows roughly the shape of the probability distributions for High Tech, U.S. Rubber, and T-bills. Suppose you suddenly remembered that…

What is weak-form EMH? What would you expect to see/not see if markets where weak form efficient? In other words, can you think of market events that would serve as evidence that market is or isn’t weak-form efficient?

If all investors believe that the market is efficient, could that eventually lead to less efficiency in the market? Explain with an example.

Suppose that as the economy moves through a business cycle, risk premiums also change. For example, in a recession, when people are concerned about their jobs, risk tolerance might be lower and risk premiums might be higher. In a booming economy, tolerance for risk might be higher and premiums lower.a. Would a predictably shifting risk premium such as described here be a violation of the efficient market hypothesis?b. How might a cycle of increasing and decreasing risk premiums create an appearance that stock prices “overreact,” first falling excessively and then seeming to recover?

Select all that are true with respect to the theory of market efficiency. Group of answer choices If markets are efficient, investors cannot earn positive returns If markets are efficient, it means prices are always "right" in that the reflect perfect foresight into what will happen in the future Strong form market efficiency suggests that all information, public or private, is reflected in current prices in an unbiased way Market efficiency suggests that relevant information is quickly impounded into prices If transaction costs are high, then prices are less likely to reflect all available information

Which of the following statements is/are correct?   Group of answer choices   If a market is weak form efficient it is also semi- and strong form efficient If a market is strong form efficient it is also semi- and weak form efficient If a market is semi-strong efficient it is also strong form efficient If a market is strong form efficient it is also semi-strong but not weak form efficient
