1.If a stock is purchased for $100 per share and held one year, during which time a quarterly dividend of $1.5 is paid, each quarter, and the price climbs to $130 per share. What is the rate of return?

2.What should be the price for a common stock paying $1.35 annually in dividends if the dividend will remain constant (zero growth of dividend), indefinitely, and the expected return is 5.5%?

3.If the dividend yield for year one is expected to be 4% based on the current price of $80, what will year seven dividend (DIV₇) be if dividends grow at a constant 2%?

4.What dividend per share would be reported in the financial press for a stock that currently has 4.5% dividend yield and the most recent stock price was $75?

5.What would be the stock price today if you know you will sell the stock in 2 years from today at $55/share and you expect annual dividends $2/share in year 1 and $3/share in year 2, given the discount rate is 10%?

1-month European put option for Apple (AAPL) with a strike price of $235/share sells for $10/share when Apple stock trades at $225/share. Each contract is for 100 shares of Apple stock. Draw a diagram showing the payoff and profit for the investor under different stock prices at maturity. What is the profit break-even stock price for the investor? If Apple share prices at maturity ends up being $230/share how much profit/loss will the investor make/incur?

The ________ utility that is received when an additional unit of a good is consumed is referred to as marginal utility.

If your total utility is 100 utils after consuming one piece of pizza and 140 utils after consuming the next piece of pizza, then the marginal utility of the second slice consumed is _________.

What is the substitution effect?

The price of Good Z decreases, and this causes the demand for another Good, B, to decrease. This is known as the ______________.

An electronics company is looking to develop a regression model to predict the number of units sold for a special running watch. Data is provided below: Sales (units) Price ($) Advertising ($) Holiday 500 100 50 Yes 480 120 40 Yes 485 110 45 No 510 103 55 Yes 490 108 40 No 488 109 30 No 496 106 45 Yes Compile an excel spreadsheet for the above data and determine the regression equation Answer (a) X3 = 1 if it is a holiday and 0 if not. (b) 0.4670

Answers:

Y = 596.02 - 1.09X1 +0.28X2 + 4.34X3 where X1 = Price, X2 = Advertising, X3 = Dummy Variable for Holiday

Y = 596.02 + 1.09X1 +0.28X2 + 4.34X3 where X1 = Price, X2 = Advertising, X3 = Dummy Variable for Holiday

Y = 59.62 - 1.09X1 +0.28X2 + 4.34X3 where X1 = Price, X2 = Advertising, X3 = Dummy Variable for Holiday

596.02 - 0.28X1 + 1.09X2 + 4.34X3 where X1 = Price, X2 = Advertising, X3 = Dummy Variable for Holiday

Lab 3 Java Classes and Memory Management

Multi-file Project

1. In this lab you will gain experience using classes and arrays of classes. Use the following as the beginning of a student abstract data type.

public class Student

{

private String fName ;

private String lName ;

private double[] grades;

}

This class should be in the package com.csc241. Write a program that prompts a user for a total number of students and dynamically allocates memory for just that number of Student objects in a Student[]. Then continuously re-prompt the user to enter, on a studentbystudent basis,

1. a student’s first and last name to be used in populating the class data members fName and lName with appropriate set methods. Use local String variables to hold the values entered by the user.
2. the number of grades for the student to be stored in nGrds, a local variable of the main program.

Next,

3. dynamically allocate memory for the grades and assign the resulting reference to a local double[]. Prompt the user for the nGrds values and after acquiring them all, assign the local grades array to the Student instance in the array using an appropriate set method.
4. re-use the MaxMin class you wrote in a previous lab, but also put it in the package com.csc241. Similarly, the GradeCalculator class that you created in the last assignment needs to be in the com.csc241 package. You will be using the avg and maxMin static methods that accept the grades[] in order to compute individual student statistics.
5. In order for you to calculate ensemble statistics, that is statistics for the entire class, the GradeCalculator class will need methods avg and maxMin that accept as an argument the Student[] that you dynamically allocated. These methods must loop through the individual grades[] of each Student array element in order to compute the total class average, max and min values.
6. display the results to the user, both on a per student and ensemble basis. Your output should appear as shown below. Please make note of and reproduce all the decimal formatting and other characteristics of the sample output.

As always, keep in mind all of the general rules of good program construction.

Periodic inventory by three methods; cost of goods sold

The units of an item available for sale during the year were as follows:

There are 80 units of the item in the physical inventory at December 31. The periodic inventory system is used.

Determine the ending inventory cost and the cost of goods sold by three methods. Round interim calculations to one decimal and final answers to the nearest whole dollar.

Consider the Ultimatum Game, a two-player game often played in experimental economics labs. In the Ultimatum Game, one player is given an amount of money and then instructed to give some arbitrary portion of it to an anonymous second player. The second player has the option of accepting the offer or rejecting it. If the second player rejects the offer, neither player gets anything. Now answer the following question if the First Player is given $100:

(a) According to traditional economic theory (which assumes that individuals are self-interested utility maximisers), what should the first player offer the second? (b) What does traditional economic theory suggest the second player should be willing to accept? (c) In experimental settings, the first player often offers the anonymous second player between 40% of the initial amount. Is this result consistent with theory? How can we explain the differences between theory and the experimental findings?

There will be three grades for each student in "grades.txt" (see example file bellow). In "student.txt" there are two students first and last names. In "grades.txt" the grades for each student will be on the same line number as the students name was on in "students.txt".

So if line 1 of "students.txt" contains:

Joe Blow

then line 1 of "grades.txt" would contain Joe Blow's grades:

85 54.3 56

Into an output file called "report.txt" output the student's last name then a comma the their first name. Following this, calculate their average and assign a letter grade using the following scale:

'A': grade >= 90

'B': 90 > grade >= 80

'C': 80 > grade >= 70

'D': 70 > grade >= 60

'F': grade < 60

If the final grade of a student is greater than 100 instead of printing their letter grade output the statement "Teacher was far too easy". The "report.txt" should have a heading on each of the columns the first saying "Student's Name" and the second saying "Student's Grade".

Select the correct answer:

A (legal; natural) monopoly exists when one firm can meet the entire market demand at a lower average total cost than two or more firms could.

A monopoly that is able to sell different units of a good or service for different prices is a (natural-price; price-discriminating) monopoly.

The act of obtaining special treatment by the government to create an economic profit is called (government surplus; rent seeking).

Regulated firms have an incentive to inflate their costs under (rate of return; price cap) regulation.

The U.S. Postal Service has a (natural; legal) monopoly on first class mail delivery.

A (single-price; price discriminating) monopoly maximizes profit by producing the quantity at which marginal revenue equals marginal cost and then charging the maximum price that consumers are willing to pay for that quantity.

The key idea behind price discrimination is to convert (consumer surplus; producer surplus) into economic profit.
