Answer all questions (total 100 points: [35 points] antonio takes out of his wallet and puts it in a box. He then offers the following deal to bob and carla. Each of them has to write down on a piece of paper how many lottery tickets he/she wants to buy at the price of each. They are to do so simultaneously and secretly, so that neither of them gets to see how many tickets the other offers to buy. Antonio will then open the two pieces of paper, reveal how many tickets each of them offered to buy and proceed to sell them those tickets. On each ticket he will write the name of the buyer. He will then collect those tickets, put them in a hat, shuffle them very well and pick one as the winner. The winner gets the box with the . (a)

3. At Nice Price for the Ice, an ice cream parlor, customers routinely buy a scoop of ice cream for $3. If consumers purchase one scoop of ice cream at $3, then why don't they keep buying more and more scoops for $3 until the store sells out?

People would not want more than one scoop of ice cream because then they would have less money to spend on other goods.

People do not want to consume all the scoops of ice cream because their total utility is higher the less they eat.

At some point, customers do not value an additional scoop at $3, so they will not pay $3 for a scoop after they reach that point.

4. Suppose you plan on eating 50 potato chips. As you start consuming potato chips, your marginal utility is very high, but it begins to fall slowly until you've eaten 10 chips. After you have eaten 10 chips, your marginal utility decreases even faster with each additional chip. The marginal utility continues to decline until you've eaten 49 chips. The fiftieth chip does not give you any additional utility. After 50 chips, your mouth gets so salty that it's unpleasant to eat anymore, so marginal utility is actually negative for those chips. How many chips should you eat in order to maximize your total utility?

6. At current levels of consumption, Alice is spending her entire budget. If Alice gets 3 utils of satisfaction per dollar spent on ice cream and 2 utils per dollar spent on shampoo, then how should she adjust her consumption to get closer to the consumer optimum?

She is already at the consumer optimum, so no adjustment is necessary.

She should buy more ice cream and less shampoo.

She should buy more shampoo and less ice cream.

She should buy more of both goods.

7. Suppose you are at a restaurant and your favorite dish costs $20. You can get your next-favorite dish for $17. If your next-favorite dish gives you 100 utils, how many additional utils do you need from your favorite dish to spend the extra $3?

117.65

8. The diamond water paradox is the observation that water is essential to life and inexpensive, while diamonds are not essential and are highly-priced. Which of the other pairs of goods exhibit a pricing structure similar to water and diamonds?

economy & luxury cars

rice & truffles (very expensive mushrooms)

paper clips & gasoline

paper & textbooks

9. Rice is a cheap staple food eaten several times a day by many people all over the world. In Trufflelandia, residents also eat expensive mushrooms known as truffles once every year as a birthday celebration. Rice keeps the people alive and truffles are not necessary for sustaining their lives. Why is rice so cheap and truffles so expensive?

Truffles taste better, so they are worth more money.

Rice is easy to cook, so people buy a lot of it. If people are going to buy so much, then it has to be cheap.

Truffles are more nutritious, and healthy food is always more expensive than unhealthy food.

People eat so much rice that an additional serving of rice has little marginal value, but the marginal value of another serving of truffles is very high.

CLASS NOTES ARE LOCATED WHERE IT SAYS CLASS NOTES!

During the early 1700s, a sailing ship is wrecked on an uninhabited island in the Caribbean Sea. The passengers and crew survive but lose all their possessions. There is no source of fresh water on the island, but coconut palm trees are fairly abundant, and the survivors are able to drink milk harvested from coconuts. There are no mammals living on the island, but many birds roost there, and these become a source of meat. There are a number of mango trees that provide fruit. A long, tough form of sawgrass grows in a number of different places on the island. This grass can be woven into knee-length sleeveless shirts, which are the basic type of clothing for people of both genders. The people on this island have developed a simple system of direct market exchange. Currently, two mangos trade for five coconuts, six coconuts trade for a pound of meat, and three pounds of meat trade for four shirts.

1. Use a formula that was stated in class, and in my notes, to calculate the total number of distinct relative prices in the islandâs economy. Note that when this formula is used to count relative prices, any given pair of goods is considered to have only one relative price. For example, if we count the price of a pound of meat in mangos as one relative price, then we donât count the price of mangos in pounds of meat as a second relative price.

(Class Notes: In a barter economy with markets, each good should have a market price, per unit, in terms of each of the other goods: baskets of fish per bushel of apples, bags of coconuts per bushel of apples, etc. A price of this type â units of one good per unit of the other good â is called a relative price (alternatively, a barter price). If there are different goods traded in an economy, then there turn out to be relative prices for a merchant to keep track of, in each market he visits. Each of the n goods has unit prices: one for each of the other goods. We divide by two to avoid counting reciprocal duplicates: if it costs 2 bags of coconuts to buy a bushel of apples, then it costs 1/2 bushel of apples to buy a bag of coconuts, and so on. )

2. Use the price information you are given to calculate all the distinct relative prices. Remember that the prices we are interested in are unit prices. A unit price is the price of a single unit of one good in units of another good. For each pair of goods, use the order that produces the highest unit price. In the case of coconuts and shirts, for example, if the price of a shirt in coconuts is higher than the price of a coconut in shirts, then report the first price but not the second one. Note: In calculating unit prices, donât worry about issues of divisibility. Assume that any good can be divided in any way, so that fractions or decimals can be components of unit prices.

3. For each relative price you just calculated, calculate the relative price if the order of the two items is switched. (In the scenario above, for example, you would now calculate the price of a coconut in shirts.) What very simple formula can you use to do this? Explain briefly.

4. Now suppose the people on this island start using mangos as money. The relative prices on the island do not change, and the absolute prices are consistent with them. a. Use a formula stated in class, and in my notes, to calculate the total number of absolute prices in the islandâs economy. b. Report these absolute prices.

Class Notes: ( In a monetary economy, in contrast, each good has a single absolute price (alternatively, a money price), which is its unit price in terms of money: dollars per bushel of apples, etc. If we assume that one of the n goods is used as money, then a merchant only needs to keep track of absolute prices. As long as there are more than two different goods ( ), it turns out that , and the difference between these two numbers gets very big as n gets large. Even if there are only 10 different goods, then there are 45 relative prices and only 9 absolute prices. And if there are 100 different goods, which is a more realistic number, then there are 99 absolute prices but almost 5000 relative prices.)

5. Comment briefly on the potential advantages and disadvantages of using mangos as money, using our list of the desirable properties of money as a guide.

6. Suppose you are a merchant on this island, where mangos are used as money in the market (see Item 4 above). A competing merchant who dislikes using money in transactions is willing to trade coconuts for shirts (or vice-versa) directly, at a rate of five coconuts per shirt. Explain, carefully and completely, how you could use this merchantâs willingness to trade these two goods, at this rate, in order to make a profit of one unit of money for yourself by (1) using money to buy units of a good in the market, (2) trading those units of the good to this merchant, in exchange for units of another good, and (3) selling those units in the market for money. Identify the items traded and the quantities, and verify the amount of the profit. Finally, explain what you would need to do in order to make a larger profit (double, for example).

Objectives:

ÃÂ· Experience some of the features of group work and teamwork

ÃÂ· Understand what managers and organizational developers do to transform

ÃÂ· groups into teams

ÃÂ· Articulate the tangible benefits (both quantitative and qualitative) of

ÃÂ· high-performing teams

ÃÂ· Finish with an interest in learning more about these concepts and

ÃÂ· techniques to apply what you learn

Background: For this assignment, you will plan and play a game with your family or friends, or at work based on the idea of the classic prisoner's dilemma. If you have had a class on game theory, you will be well aware of this concept. It forms the basis of many TV game shows. The prisoner's dilemma was illustrated in Truman Capote's book, "In Cold Blood" concerning the 1959 robbery of a Kansas farmhouse by Perry Smith and Dick Hickock, who murdered their victims in order to eliminate the witnesses. After the men were captured, the police interrogated them separately. To get a confession, the police offered the men a reduced sentence for cooperating. Failure to cooperate would result in a death penalty charge for both.

In the prisoner's dilemma, if both parties cooperate they are mildly punished; if one betrays another, one is severely punished while the other goes free; and if both betray one-another, both are moderately punished. Can you think of settings where you work in which the organizational structure has created a prisoner's dilemma? Competition can (but does not necessarily) bring out conflict.

In game theory, there are non-cooperative and cooperative games. A non-cooperative zero-sum game has a definite winner and loser. For one to win, one must lose. We often think of politicking as an element of that. A cooperative game is where everyone who plays is better off for having played than not having played the game. That is not to say that everyone is equally well off, but simply better off than they were before playing. Hence, even in a cooperative game, some people will likely benefit more than others.

Instructions

Review in your textbook, the Big Five personality dimensions, pp. 82Ã¢ï¿½ï¿½84, and then consider the 3.1 Personality Insights inventory, pp. 89Ã¢ï¿½ï¿½91
Select four or five friends, coworkers, or family members and have them take the personality inventory
Plan and play a game with the participants
Write a 5-10 page paper that addresses the assignment questions below

As you plan and play your game, you will negotiate the type of game you want to play and your role in it. Strive to determine some personal characteristics of the game participants a head of time, or by observing them. Consider how the personal characteristics of the individuals in the game manifest themselves in the informal roles they assume during the planning and execution of the game.

For the purpose of this assignment, you will want both a cooperative and a competitive element. To do that, you can form several groups to compete and cooperate with each other, or you can have individuals in one group compete and cooperate. You can use rewards and/or punishments to create the competitive/cooperative motivations.

Evaluation: When groups are formed, we want to consider how organizational structures, processes, and situations impact on group motivation, politics, and goals achievement. Alignment of all of these structural, personal, and interpersonal components will help to ensure that the group will meld into a team. A defining feature of teamwork (versus group work) is cooperation!

One of the factors that affect cooperation is conflict. Conflict is defined as when someone perceives that his/her interests are opposed or negatively impacted by another. Conflict can at times produce positive results depending on the basis for the conflict and how the conflict is handled (functional conflict). The worst kind of dysfunctional conflict produces betrayal.

Note that team performance can be observed in how well the team coordinates their interdependencies, works efficiently, communicates, and accomplishes their mission. Consequently, as you implement your game, assess your players based on these factors and the informal roles they play.

After you have played the game, reflect on the personality assessments your participants took, and then consider how they planned and played the game.

Write a (5- 10) page analysis to address the following questions:

1. How well did the personality assessments reflect in the behaviors participants displayed during the game?

2. What do these assessments tell us about how we perceive ourselves versus how others perceive us?

3. What informal roles did participants assume during the game, and were they different from the planning portion from the playing portion of the exercise?

4. What did I learn about myself? For example, did the exercise show that you have characteristic ways of relating to others that are distinctive, or similar, to those the others? Did the exercise show that in a particular type of situation you acted in a particular way, or that when others acted in a particular way, you felt happy or anxious or angry, etc.?

5. What did I learn about someone else in the exercise? Did you see something new about them, such as "they seemed more capable than I imagined," or "inattentive when things were stressful?"

6. In playing your game, what could you have done to increase cooperative behaviors?

7. Based on your game experience, what are some of the key factors involved in gaining cooperation from people in a business setting?

8. How would you go about getting cooperation from a "difficult" co-worker? Give an example or scenario.

Please provide a unique type of game theory preferably instead of Mafia Game.
