Marta and Sara are two students that devote part of their free time to doing surveys for a market research company. The income obtained from this activity depends on the number of surveys they do, bearing in mind that the girls may freely choose the interviewees. As they both live in the same neighborhood in case, they just interview their neighbors (N), they compete for the same people and their monthly income is about 250 Euros. If they both choose to go to other neighborhoods of the city and interview strangers (S), they can carry out more surveys and both their incomes would be 400. If one of them decides to go and interview people in another neighborhood but the other one does not, the former will obtain income for 500, and the latter for 300, and vice versa. After receiving the order from the company, Marta is always the one who starts to work first. Sara has information about the places where Marta has done the surveys. Please:…
A major proposed industry in the future is the provision of global satellite wifi. However, the actual willingness to pay for such a service is unknown. Assume there's a 40% chance that there are 1 billion people willing to pay $100/year for a service that would cost $60/year to provide and a 60% chance that those people would be willing to pay $10/year for a service that would cost $60/year to provide. Assume that the enterprise involved with this risky industry has an interest rate or discount rate of 20%.a. What is the expected value, annually, of providing this service?b. Assume that you could spend $75 billion to launch a testbed of the program, that could then either be scrapped if the willingness to pay were $10 or continue at normal cost afterward (for simplicity, assume that the program will last forever and generate constant annual returns if it is continued) if the willingness to pay were $100. What is the net expected value of this testbed?

In this course, you will conduct an analysis of your organization with the goal of creating a plan to improve an aspect of your organization’s performance.

As the two products have been recently improved, both firms are planning to launch an advertising campaign. If neither firm advertises, their market share remains the same. If one of them launches a more powerful advertising campaign, the other loses a proportional percentage of its customers. Market research indicates that it is feasible to reach 50 % of potential customers by TV, 30 % through the press and 20 % on the radio. a. Develop the payoff matrix b.

- A recently discovered painting by Picasso is on auction at Sotheby's. There are two main bidders Amy and Ben {1,2}. Bidding starts at £10M but the value of the painting is certainly not more than £20M. Each bidder's valuation v; is independently and uni- formly distributed on the interval [10M, 20M], and this is common knowledge among the players: A bidder knows their own valuation but not of their opponent. Consider an auction where an object is allocated to the highest bidder but the price paid by the bidder is determined randomly. With probability 3/4, the bidder pays their own bid, and with probability 1/4 the bidder pays the losing bid. The person bidding lowest pays nothing. If the bids are equal, each bidder gets the object with probability one-half, and in this case, pays their bid. Suppose that bidder 1 assumes that bidder 2 will bid a constant fraction, 7, of bidder 2's valuation (and similarly, bidder 2 assumes bidder 1 will bid the same constant propor- tional value of…arrow_forwardThe research department at a manufacturing company has developed a new process that it believes will result in an improved product Management must decide whether to go ahead and market the new product. The new product may or may not be better than the old one. If the new product is better and the company decides to market it, sales should increase by $50,000. If it is not better and they replace the old product with the new product on the market, they will lose $24,000 to competitors. If they decide not to market the new product, they will lose a total of $30,000 if it is better and just research costs of $10,000 if it is not. Answer parts a through c below. (a) Prepare a payoff matrix. (Type an integer or decimal for each matrix element. Do not include the $ symbol in your answer.)

- The city council is to decide on a proposal to raise property taxes. Suppose Ms. Tuttle is the chair and the council’s other two members are Mr. Jones and Mrs. Doubtfire. The voting procedure works as follows: Excluding the chair, Mr. Jones and Mrs. Doubtfire simultaneously write down their votes on slips of paper. Each writes either for or against the tax increase. The secretary of the city council then opens the slips of paper and announces the vote tally. If the secretary reports that both slips say for, then the tax increase is implemented and the game is over. If both vote against, then the tax increase is not implemented and, again, the game is over. However, if it is reported that the vote is one for and one against, then Ms. Tuttle has to vote. If she votes for, then the tax increase is implemented, and if she votes against, then it is not. In both cases, the game is then over. As to payoffs, if the tax increase is implemented, then Mrs. Doubtfire and Mr. Jones each receive a…arrow_forwardIn the post lockdown scenario it is expected that with economic activity slowing down,impacting buying power of consumers, demand will shift towards smaller cars or low price carsand first time buyers.

Each can sell a large coffee for either $1 or $2 with 60% of the price being profit. It is expected that 2000 large coffees will be bought by UTA students per month at the two coffee shops and 1000 per month by non-students. Students choose the shop with the most inexpensive coffee if possible. When the prices are the same, students are equally likely to choose either coffee shop. Non-students are always equally likely to choose either coffee shop. If the goal of both coffee shops is to maximize profit for large coffees (and thereby all coffee hopefully), what would be the strategies for both coffee shops in a two-person game? $1 and $2 O 1000 and 2000 O 80% and 20% O none of the other choices « Previous Next Simpfunarrow_forward

Each of the drivers must decide whether to come to place S via point G or via point D (see the directed graph below). The travel time on segments G-S and K-D is not dependent on the number of drivers: each driver traverses the G-S segment in 60 minutes, and the K-D segment in 45 minutes, regardless of the number of drivers. However, the travel time on segments K-G and D-S depends on the number of drivers: if x drivers travel on the K-G segment, each driver on this segment consumes 0.005x minutes; if x drivers travel on the D-S segment, each driver on this segment consumes 0.01x minutes (see the directed graph below). Assume that all people start simultaneously and do not know the decisions of other people. Find all pure Nash equilibria of the game.arrow_forward(b) Two hotels, Hotel Sandy and Hotel Magda, are competing for a limited number of tourists. The hotels have approval to either expand hotel operations, or add recreational water sports to their offerings. No one hotel has approval do both of these changes. A research company has determined that the following outcomes are likely: If Hotel Sandy expands, and Hotel Magda adds water sports, Hotel Sandy will increase its market share by 1%, and Hotel Magda will increase its market share by 3%. If Hotel Sandy adds water sports, and Hotel Magda expands, Hotel Sandy will decrease its market share by 5%, and Hotel Magda will increase its market share by 2%. If both hotels add water sports, Hotel Sandy will increase its market share by 4%, and Hotel Magda will increase its market share by 5%. If both hotels expand, Hotel Sandy will increase its market share by 2%, and Hotel Magda will decrease its market share by 5%.
