Clever tests to discriminate between alternative explanations. LaPorta, Lakonishok, Shleifer, and Vishny ("Good News for Value S

tocks," Journal of Finance, June 1997) study the returns on stocks on the few days surrounding their quarterly earnings announcements (relative to various expected return benchmarks). They find that on average, high-B/M stocks earn 0.9% around an earnings announcement. In contrast, low-B/M stocks earn an average of -0.1% around an earnings announcement. The difference is statistically significant.
Discuss whether the return pattern found by LaPorta et al. (1997) around earnings announcements is more consistent with the irrational expectations (behavioral) view, or the risk factor (efficient markets) view of the book-to-market effect, and explain your logic.

In the long run, the competitive firm's supply curve is the a. entire marginal-cost curve. b. portion of the marginal-cost curve
Mars2501 [29]

The long run will see the supply curve of a completive firm changing to the b. portion of the marginal-cost curve that lies above the average-total-cost curve.

<h3>What is the long-run supply curve in a perfect competition?</h3>

In a perfect competition, a company will only produce goods and services at a level where the marginal cost curve is above the average total cost in the long run.

This means that the supply curve will be the marginal cost curve but only the portion of this curve that is above the long-run average total cost curve.

The reason for this is that in the long-run., all the costs in a perfectly competitive firm are considered variable and so they can afford to avoid supply mishaps in the short term.

In conclusion, option B is correct.

Ksivusya [100]

Answer:

The correct answer is:

True (A)

Explanation:

Customer access strategy is a framework or a set of standards, guidelines and processes, which defines the means by which a customer and the organization can interact, and  means by which the customer has access to:

  • the relevant information needed to make purchases
  • the right logistics for the execution of a purchase

The arear of access are mainly information (value of the product, price of products, how products work) and logistics (means of getting the products, customer service on the after-purchase needs etc).

It has been studied extensively that companies are spending 3 to 4 times as much money on creating customer access than they do on advertising, this is because even if advertising is successful, the results will not be seen if customer access is not successful, and having an efficient customer access strategy can provide a competitive advantage to the producers.
