Global Investments Are Still a Good Bet

Investors in global equity markets have traditionally hedged their bets, casting their investments far and wide across the world. That way, if the market in one country or region stagnated (think Japan in the 1990s or Europe in the 2000s), they could make up the difference in other sectors that are booming.

However, as markets in different countries have increasingly moved in tandem or correlated, from 50 or 60 percent in the 1990s to more than 90 percent after the financial crisis of 2008, that strategy has seemed less and less worthwhile.

“The claim is that it makes less sense to be diversified than it used to be in the past, since, at the end of the day, all markets are moving together,” says Luis Viceira, George E. Bates Professor and Senior Associate Dean for International Development at Harvard Business School.

All things being equal, that means instead of spreading the wealth around, investors should put their money in places that are familiar—usually their own country. “There is a very well-known phenomenon called home bias,” continues Viceira. “People think they know their own stock market and feel more comfortable investing in it, and they overestimate the risks of investing abroad.”

Required: Is there any disadvantage of being affected by Home Bias? Discuss with reasoning.

Three Cournot competitors produce in a market with indirect demand

P (Q) = 15- Q

The marginal cost for all firms is constant and equals 3.
a). What are the Cournot equilibrium quantities, price, and firm profits?
b) Two of the three firms want to merge. Calculate the new equilibrium quantities, price, and firm profits if
the post-merger market structure is the asymmetric duopoly.
c). Compare the merged firms’ pre- and post-merger profits. Is this merger good for the merging firms? for
consumers? for the outside firm?

Beyond starting and running new businesses, entrepreneurs are change agents who transform innovation into reality. Apple Inc. is known as one of the world's most innovative companies, and it co-founder Steve jobs was credited with Apple's most important breakthrough innovations. Steve Jobs also founded Pixar, one of the most successful film studios of all time. He was clearly an entrepreneur extraordinaire, and created continuous innovation in his quest to create value through new products or services. Jeff Bezos, and Elon Musk are also entrepreneurs that stand out as examples of successful entrepreneurs. Discuss the traits and behaviors of these entrepreneurs that might have contributed to the outstanding record of innovation in the companies they led. What are the major differences in how these individuals have approached entrepreneurship? How have those differences impacted the organizations they have founded?  

Cost savings are likely to be greatest when firms with dissimilar operations are merged or consolidated. True or False

An article appeared in an Australian newspaper. It described a study of academic performance and attention span and reported that the mean time to distraction for teenage boys working on an independent task was 5 minutes. Although the sample size was not given in the article, suppose that this mean was based on a random sample of 50 teenage Australian boys and that the sample standard deviation was 1.5 minutes.

Is there convincing evidence that the average attention span for teenage boys is less than 6 minutes? Test the relevant hypotheses using

α = 0.01.

(Use a statistical computer package to calculate the P-value. Round your test statistic to two decimal places and your P-value to three decimal places.)

Assume that different groups of couples use a particular method of gender selection and each couple gives birth to one baby. This method is designed to increase the likelihood that each baby will be a​ girl, but assume that the method has no​ effect, so the probability of a girl is 0.5. Assume that the groups consist of 31 couples. Complete parts​ (a) through​ (c) below.

a. Find the mean and the standard deviation for the numbers of girls in groups of 31 births.

b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high.

Values of ___ girls or fewer are significantly low. ​(Round to one decimal place as​ needed.)

Values of ___ girls or greater are significantly high. (Round to one decimal place as​ needed.)

c. Is the result of 31 girls a result that is significantly​ high? What does it suggest about the effectiveness of the​ method?

The result is/is not significantly​ high, because 31 girls is greater than/equal to/less than ___ girls. A result of 31 girls would suggest that the method is not effective/is effective.​(Round to one decimal place as​ needed.)

PLEASE HAND ONE SAMPLE T. TEST

The county collector of Suncoast County is responsible for collecting all property taxes levied by funds and governments within the boundaries of the county. To reimburse the county for estimated administrative expenses of operating the tax custodial fund, the custodial fund deducts 1.5 percent from the collections for the town, the school district, and the other towns. The total amount deducted is added to the collections for the county and remitted to the Suncoast County General Fund.

The following events occurred during the year:

1. Current-year tax levies to be collected by the custodial fund were

2. $13,700,000 of current taxes was collected during the first half of the year.
3. Liabilities to all funds and governments as a result of the first half-year collections were recorded. (A schedule of amounts collected for each participant, showing the amount withheld for the county General Fund and net amounts due the participants, is recommended for determining amounts to be recorded for this transaction.)
4. All cash in the tax custodial fund was distributed.
5. All additions and deductions were recorded by the custodial fund. Additions and deductions are aggregated because resources are held less than three months.

Prepare journal entries for each of the foregoing transactions that affected the tax custodial fund.

A clinical trial tests a method designed to increase the probability of conceiving a girl. In the study 400 babies were​ born, and 320 of them were girls. Use the sample data to construct a 99% confidence interval estimate of the percentage of girls born. Based on the​ result, does the method appear to be​ effective?

? < p < ?

​(Round to three decimal places as​ needed.)

Does the method appear to be​ effective?

No​, the proportion of girls is not significantly different from 0.5.

or

Yes​, the proportion of girls is significantly different from 0.5.
