. In 1973, the Basic Education Opportunity Grant (later renamed the Pell Grant) was established to provide grant aid to low-income students—not just recent high school graduates (“traditional students”) but also older students who might be returning to school (“nontraditional students”). The program was intended to increase college enrollment among the students most likely to face difficulties financing a college education. a. How is the effect of the Pell grant on college enrollment different for a student who is in his mid-20s than for a recent high school graduate?

The Ministry of Education wants to know whether attending a private school has a positive causal effect on student test scores. The Ministry provides you with data that covers all students in the province of Ontario. The data include each student's grade average and whether he or she attends a public or private school. Note that attending a private school is an active choice made by students and parents (all students are guaranteed a spot in a public school) and students are required to pay tuition to attend (public schools are free).
You define the independent variable of interest as
??= 1 if student attends a private school
0 otherwise
Let ??? denote the grade average of student ?. You consider estimating the following regression in order to evaluate the effect of attending a private school on student grade average:
???=?0+?1??+??
Please answer the following questions.
a/ Interpret the parameter ?0. What does it represent?
b/ Interpret the parameter ?1. What does it represent?
c/Using the econometric model given by the equation above (???=?0+?1??+??), write down (mathematically) the condition that must be satisfied for OLS estimation of this model to result in an unbiased estimate of ?1. Now interpret this condition (in words). Do you think the condition is satisfied?
d/ Would your answer to question (1c) above change if heteroskedasticity was present in this model? If so, explain how. If not, why not? Make sure to (briefly) define heteroskedasticity in your answer.

Consider Gavin, a new freshman who has just received a Stafford student loan and started college. He plans to obtain the maximum loan from Stafford at the beginning of each year. Although Gavin does not have to make any payments while he is in school, the unsubsidized 6.8 percent interest owed (compounded monthly) accrues and is added to the balance of the loan. UNSUBSIDIZED Stafford loan limits: Freshman $6,000 Sophomore 6,000 Junior 7,000 Senior 7,000 After graduation, Gavin gets a 6-month grace period. This means that monthly payments are still not required, but interest is still accruing. After the grace period, the standard repayment plan is to amortize the debt using monthly payments for ten years. a. Show a time line of when the loans will be taken. b. What will be the loan balance when Gavin graduates after his fourth year of school? c. What is the loan balance six months after graduation? d. Using the standard repayment plan and a 6.8 percent APR interest rate, compute the monthly payments Gavin owes after the grace period.

In March 1976, plaintiff Albin Laaperi purchased a smoke
detector from Sears. The detector, manufactured by the Pittway
Corporation, was designed to be powered by AC (electrical) current.
Laaperi installed the detector himself in one of the two upstairs
bedrooms in his home.
Early in the morning of December 27, 1976, a fire broke out in the
Laaperi home. The three boys in one of the upstairs bedrooms were
killed in the blaze. Laaperi’s 13-year-old daughter Janet, who was
sleeping in the other upstairs bedroom, received burns over 12
percent of her body and was hospitalized for three weeks.
The uncontroverted testimony at trial was that the smoke detector
did not sound an alarm on the night of the fire. The cause of the
fire was later found to be a short circuit in an electrical cord
that was located in a cedar closet in the boys’ bedroom. The
Laaperi home had two separate electrical circuits in the upstairs
bedrooms: one which provided electricity to the outlets and one
which powered the lighting fixtures. The smoke detector had been
connected to the outlet circuit, which was the circuit that shorted
and cut off. Because the circuit was shorted, the AC-operated smoke
detector received no power on the night of the fire. Therefore,
although the detector itself was in no sense defective (indeed,
after the fire the charred detector was tested and found to be
operable), no alarm sounded.
Laaperi brought this diversity action against defendants Sears and
Pittway, asserting negligent design, negligent manufacture, breach
of warranty, and negligent failure to warn of inherent dangers. The
parties agreed that the applicable law is that of Massachusetts.
Before the claims went to the jury, verdicts were directed in favor
of defendants on all theories of liability other than failure to
warn.…
Laaperi’s claim under the failure to warn theory was that he was
unaware of the danger that the very short circuit which might
ignite a fire in his home could, at the same time, incapacitate the
smoke detector. He contended that had he been warned of this
danger, he would have purchased a batterypowered smoke detector as
a back-up or taken some other precaution, such as wiring the
detector to a circuit of its own, in order better to protect his
family in the event of an electrical fire.
The jury returned verdicts in favor of Laaperi in all four actions
on the failure to warn claim. The defendants’ motions for directed
verdict and judgment notwithstanding the verdict were denied, and
defendants appealed.
The Court affirmed the judgment in favor of Albin Laaperi in his
capacity as administrator of the estates of his three sons. In the
action on behalf of Janet laaperi, the verdict of the jury was set
aside, the judgment of the district court was vacated, and the
cause was remanded to the district court for a new trial limited to
the issue of damages.
1. This a US Court of Appeals case from the First Circuit in Massachusetts. Why is this case in federal court?
2. Why does the court talk about its “sense of the current state of tort law in Massachusetts” and how this case “would be treated by the Massachusetts courts,” as if it were not in the state at all but somehow outside?
3. What rule of law is in play here as to the defendants’ liability?
4.This is a tragic case—three boys died in a house fire. Speaking dispassionately—if not heartlessly—though, did the fire actually cost Mr. Laaperi, or did he lose $3.4 million (in 2010 dollars) as the result of his sons’ deaths? Does it make sense that he should become a millionaire as a result? Who ends up paying this amount? (The lawyers’ fees probably took about half.)
5. Is it likely that smoke-alarm manufactures and sellers changed the instructions as a result of this case?

You are preparing a statement of activities for the University of Richland, a private not-for-profit entity. The following questions should be viewed as independent of each other.
Part 1
During the current year, a donor gives $386,000 in cash to the school and stipulates that it must hold this money forever. However, any investment income earned on this money must be used for faculty salaries. During the current year, the investment earned $42,000 and, of that amount, the school has expended $29,000 appropriately to date. As a result of these events, what was the overall change in each of the following for the current year?
Unrestricted net assets.
Temporarily restricted net assets.
Permanently restricted net assets.
Part 2
A donor gives a large machine to the school on January 1 of the current year. It has a value of $201,000, no salvage value, and a 10-year life. The donor requires that the school keep the machine and use it for all 10 years, and the school agrees. It cannot sell or retire the machine in the interim. As a result of these events, what was the overall change in each of the following for the current year?
Unrestricted net assets.
Temporarily restricted net assets.
Operating expenses.
Part 3
Several years ago, a donor gave the school $430,000 in cash to help fund its financial aid program. This year, the school charged $2.40 million in tuition but granted $740,000 in financial aid. Collections to date from the students have totaled $1.50 million. The donor’s gift has offset $310,000 of the financial aid. As a result of these events, what was the overall change in each of the following for the current year?
Unrestricted net assets.
Operating expenses.
Temporarily restricted net assets.
