Practice with value of single time events.

1. Imagine you are given the $100 today. If you invest it, how much will it be worth in 5 years if the annual rate of interest is 10%?
2. How much would that $100 be worth in 5 years if the annual rate of interest is 5%?
3. What is the Present Value of $100 given to you in 5 years if the discount rate is 10%?
4. What is the Present Value of $100 given to you in 5 years if the discount rate is 5%?

D. 500, 100, 500, 900

E. 500, 1000, 600

Think of a time when you were involved in strategic decision making. This could be a business situation or a personal situation. It could be anything from purchasing inputs for a manufacturing firm to trying to divide up household chores. Strategy is huge in sports – Should we punt or go for it on 4^th?

When I purchased my car. I looked for the type and color of the car first in the city and online. I looked for a certain price range and distance. I then contacted my credit union to see exactly how much I qualified for and then I began the more serious process by test driving cars here in the city and speaking with salesman over the phone from online cites out of the city. Of course let me not forget I also looked for the cars with miles under 50,000.

Discuss questions

1.Discuss your dominant strategy for the situation.

2.What was the other person’s dominant strategy?

3.Was the outcome a Nash equilibrium? Why or why not?

Please answer each part of the questions and use game theory terminology. Make sure that you have an adversarial situation with at least two parties.

Have fun with this! These are useful tools to understand for your everyday life!

Game Theory Help!

For questions 1-3, you will need to determine whether or not each firm has a dominant strategy in order to know if the game is a Prisoners’ Dilemma.

A dominant strategy is one in which the agent (the firm, in this case) would have no incentive to change its strategy regardless of what the other agent does. I like to do this...

1. Pretend that Lowe’s chooses first. Write down Lowe's best response to each of Home Depot's choices. That is, what should Lowe’s do if Home Depot picks “cooperate” and what should Lowe’s do if Home Depot picks “don’t cooperate”.

2. Do the same for Home Depot choosing its strategy first. Write down Lowe's best response.

3. If you get that the firm always chooses “cooperate” for example, then “cooperate” is the dominant strategy. If the firm always chooses “don’t cooperate”, then “don’t cooperate” is its dominant strategy. If you get one of each chosen, there is no dominant strategy for that firm.

Questions 4-7 are very similar, but you will need to determine the Nash and strategically stable outcome (if there is one)

1. Pretend that the Saint Petersburg Times chooses first. Write down Tampa's best response to each of SPT's choices. That is, what should Tampa do if SPT picks low price and what should Tampa do if SPT picks high.

2. Do the same for Tampa choosing its price first. Write down SPT's best response.

3. If you get that the firm always chooses Low, for example, then Low is the dominant strategy. If the firm always chooses High, then High is its dominant strategy. If you get one of each chosen, there is no dominant strategy for that firm.

4. To get the Nash Equilibrium, for each firm, ask yourself, "What is the worst case scenario for this firm." Then, pick the opposite strategy. Put a little dot in that square (the opposite of the worst case scenario). Do the same for the other firm. If there is a Nash, it will be the square with 2 dots.

5. Finally, the Nash equilibrium is the only strategically stable outcome. Both firms are doing the best that they can, so there is no incentive for them to deviate from that strategy.

Task #2a Using the Scanner Class for User Input (4 pts)
⦁   Add an import statement above the class declaration to make the Scanner class available to your program.
⦁   In the main method, create a Scanner object and connect it to the System.in object.
⦁   Prompt the user to enter his or her first name.
⦁   Read the name from the keyboard using the nextLine method and store it into a variable called firstName (you will need to declare any variables you use).
⦁   Prompt the user to enter his or her last name.
⦁   Read the name from the keyboard and store it in a variable called lastName.
⦁   Concatenate the firstName and lastName with a space between them and store the result in a variable called fullName.
⦁   Print out the fullName.
⦁   Compile, debug, and run, using your name as test data.
⦁   Since we are adding on to the same program, each time we run the program we will get the output from the previous tasks before the output of the current task.
Task #2b (alternate) Using Dialog Boxes for User Input (4 pts)
⦁   Add an import statement above the class declaration to make the JOptionPane class available to your program.
⦁   In the main method, prompt the user to enter his or her first name by displaying an input dialog box and storing the user input in a variable called firstName (you will need to declare any variables you use).
⦁   Prompt the user to enter his or her last name by displaying an input dialog box and storing the user input in a variable called lastName.
⦁   Concatenate the firstName and lastName with a space between them and store the result in a variable called fullName.
⦁   Display the fullName using a message dialog box.
⦁   Compile, debug, and run, using your name as test data.
⦁   Since we are adding on to the same program, each time we run the program we will get the output from the previous tasks before the output of the current task.

Task #3 Working with Strings (4 pts)
⦁   Use the charAt method to get the first character in firstName and store it in a variable called firstInitial (you will need to declare any variables that you use).
⦁   Print out the user’s first initial.
⦁   Use the toUpperCase method to change the fullName to uppercase and store it back into the fullName variable.
⦁   Add a line that prints out the value of fullName and how many characters (including the space) are in the string stored in fullName (use the length method to obtain that information).
⦁   Compile, debug, and run. The new output added on after the output from the previous tasks should have your initials and your full name in uppercase.
Task #4 Using Predefined Math Functions (4 pts)
⦁   Add a line that prompts the user to enter the diameter of a sphere.
⦁   Read in and store the number into a variable called diameter (you will need to declare any variables that you use).
⦁   The diameter is twice as long as the radius, so calculate and store the radius in an appropriately named variable.
⦁   The formula for the volume of a sphere is:
r3
Convert the formula to Java code and add a line which calculates and stores the value of volume in an appropriately named variable. Use Math.PI for and Math.pow to cube the radius.
⦁   Print your results to the screen with an appropriate message.
⦁   Compile, debug, and run using the following test data and record the results.

Diameter   Volume (hand calculated)   Volume (resulting output)
2      
25.4      
875,000      
Task #5 Create a program from scratch (4 pts)
In this task you will create a new program that calculates gas mileage in miles per gallon. You will use string expressions, assignment statements, input and output statements to communicate with the user.

⦁   Create a new file in your IDE or text editor.
⦁   Create the shell for your first program by entering:
public class Mileage
{
   public static void main(String[] args)
   {
       // Add your declaration and code here.
   }
}
⦁   Save the file as Mileage.java.
⦁   Translate the algorithm below into Java code. Don’t forget to declare variables before they are used. Each variable must be one word only (no spaces).
Print a line indicating this program will calculate mileage
Print prompt to user asking for miles driven
Read in miles driven
Print prompt to user asking for gallons used
Read in gallons used
Calculate miles per gallon by dividing miles driven by gallons used
Print miles per gallon along with appropriate labels
⦁   Compile the program and debug, repeating until it compiles successfully.
⦁   Run the program and test it using the following sets of data and record the results:

Miles driven   Gallons used   Miles per gallon (hand calculated)   Miles per gallon
(resulting output)
2000   100      
500   25.5      
241.5   10      
100   0      

⦁   The last set of data caused the computer to divide 100 by 0, which resulted in what is called a runtime error. Notice that runtime can occur on programs which compile and run on many other sets of data. This emphasizes the need to thoroughly test you program with all possible kinds of data.
Task #6 Documenting a Java Program (2 pts)
⦁   Compare the code listings of NumericTypes.java with Mileage.java. You will see that NumericTypes.java has lines which have information about what the program is doing. These lines are called comments and are designated by the // at the beginning of the line. Any comment that starts with /** and ends with */ is considered a documentation comment. These are typically written just before a class header, giving a brief description of the class. They are also used for documenting methods in the same way.
⦁   Write a documentation comment at the top of the program which indicates the purpose of the program, your name, and today’s date.
⦁   Add comment lines after each variable declaration, indicating what each variable represents.
⦁   Add comment lines for each section of the program, indicating what is done in that section.
⦁   Finally add a comment line indicating the purpose of the calculation.
