A large consumer goods company ran a television advertisement for one of its soap products. On the basis of a survey that was conducted, probabilities were assigned to the following events. B = individual purchased the product S = individual recalls seeing the advertisement BnS = individual purchased the product and recalls seeing the advertisement The probabilities assigned were P(B) = 0.20, P(S) = 0.40, and P(BS) = 0.12. a. What is the probability of an individual's purchasing the product given that the individual recalls seeing the advertisement (to 1 decimal)? Does seeing the advertisement increase the probability that the individual will purchase the product? - Select your answer - As a decision maker, would you recommend continuing the advertisement (assuming that the cost is reasonable)? - Select your answer - + b. Assume that individuals who do not purchase the company's soap product buy from its competitors. What would be your estimate of the company's market share (to the…

Two identically able agents are competing for a promotion. The promotion is awarded on the basis of output (whomever has the highest output, gets the promotion). Because there are only two workers competing for one prize, the losing prize=0 and the winning prize =P. The output for each agent is equal to his or her effort level times a productivity parameter (d). (i.e. Q2=dE1 , Q2=dE2). If the distribution of “relative luck” is uniform, the probability of winning the promotion for agent 1 will be a function of his effort (E1) and the effort level of Agent 2 (E2). The formula is given by...Prob(win)=0.5 + α(E1-E2), where α is a parameter that reflects uncertainty and errors in measurement. High measurement errors are associated with small values of α (think about this: if there are high measurement errors, then the level of an agent’s effort will have a smaller effect on his/her chances of winning). Using this information, please answer the following questions. Both workers have a…

43% of small businesses are either not tracking inventory or using manual processes, such as spreadsheets or pen-and-paper. This creates a higher probability of creating double entries, difficulties in placing and receiving orders, and time-consuming processes of locating stock, among other errors. Suppose you are appointed as a purchasing officer of a small business. You are asked to manage the purchases of NIDO (powder milk). The annual demand = 1500 units of NIDO, Delivered purchase cost = R25/units, Annual carrying cost percentage= 15percent, Order cost = R35/order. The lead time is 10 working days. Assuming 20 working days per month. a) Determine the Economic Order Quantityb) Determine the reorder pointc) Determine the average inventoryd) Suppose orders are placed only at review time. Find the optimal period and the optimal orderquantity.

To solve: A manufacturer of high-tech computing equipment must decide whether or not to continue development of a new promising technology. continuing the development would cost $2 Million. If the development is continued, then a patent is either awarded or not. 70% chance that the patent will be awarded and The best estimate is that there is a a 30% chance that it will not. if the patent is awarded, the company needs to decide whether or not to license the technology. it does, it would receive a total of $25 million in licensing royalties. However, the company could also produce and sell the technology in-house (at. a cost of $10 million), in which case there is an additional uncertainty about the demand for the technology. if the demand is high (p = 0.25), the company would make $55 Million in revenues, if the demand is medium (p = 0.55) the company would make $33 Million and if the demand is Low (p = 0.20) the company would still make $15 Million. a) Draw and solve a decision tree…

QUESTION 10 YouTube generates revenue by showing ads to consumers who watch videos on its website. Suppose that, for each person watching a video, YouTube receives one dollar in ad revenues (P=1). Arthur is a professional video-game player. He plays the video-game "Fortnite" and uploads his video to YouTube. The number of people who will watch his video depends on Arthur's effort producing the video and increasing its quality. The number Q of viewers as a function of Arthur's effort "e" is given by the function Q= Be. Arthur's offort cost is 202. His utility equals his income minus ys effort cost. To give incentives to Arthur to create better videos and attract more viewers, YouTube decides to pay Arthur a bonus b for each person watching his video. YouTube also has an operational cost 30 Operational cost - 32 which is the cost of maintaining its internet servers and administrative staff. YouTube's profit equals the ad revenue minus the payment to Arthur and the operational cost. Find…

Sumo wrestlers have 15 matches per tournament and the benefits of winning 8 matches (a winning record) are very large, compared to the benefits of winning a 5 matches (compared to 4) or the benefit of winning 10 matches (compared to 9). Sumo wrestlers who have won 7 matches and lost 7 matches tend to win a statistically anomalous (they win too often) amount of the time in their last match of the tournament. In order to show that this is unlikely to be explained by 'wrestlers with 7-7 record try hard to win' researchers show that wrestlers who win an 8th match in these circumstances then tend to lose a statistically anomalous amount of the time when they next face that same opponent (they lose too frequently when those wrestlers next meet). This result is consistent with 'win trading'. The researchers find that wrestlers about to retire benefit less from the 'wrestlers at 7-7 tend to win' effect. Pick the answer which best explains the fact that wrestlers tend to win an 8th match more…

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?

Exercise 1.4. There are two players. Each player is given an unmarked envelope and asked to put in it either nothing or $300 of his own money or $600. A referee collects the envelopes, opens them, gathers all the money, then adds 50% of that amount (using his own money) and divides the total into two equal parts which he then distributes to the players. (a) Represent this game frame with two alternative tables: the first table showing in each cell the amount of money distributed to Player 1 and the amount of money distributed to Player 2, the second table showing the change in wealth of each player (money received minus contribution). (b) Suppose that Player 1 has some animosity towards the referee and ranks the outcomes in terms of how much money the referee loses (the more, the better), while Player 2 is selfish and greedy and ranks the outcomes in terms of her own net gain. Represent the corresponding game using a table. (c) Is there a strict dominant-strategy equilibrium?

An amount of money is accumulating; in period t (= 1, 2, . . . , T) its size is $2t. In each period two people simultaneously decide whether to claim the money. If only one person does so, she gets all the money; if both people do so, they split the money equally; and if neither person does so, both people have the opportunity to do so in the next period. If neither person claims the money in period T, each person obtains $T. Each person cares only about the amount of money she obtains. Formulate this situation as an extensive game with perfect information and simultaneous moves, and find its subgame perfect equilibria). (Start by considering the cases T = 1 and T = 2.)

QUESTION 2 You work for a big retail chain that operates in a large number of regional markets and you want to investigate the effect of increased marketing spending on sales. You randomly select half of the markets and increase the marketing budget in these markets by 10%. The rest of the markets are allocated the same marketing budget as before. Then comparing the average sales in the markets with increased marketing budget and average sales in the remaining markets will give an unbiased estimate of the true causal effect of increased marketing spending on sales. True O False

A large hospital is soliciting competitive bids to contractors for the construction of a new wing.  The hospital’s procurement auction will use a first-price sealed-bid mechanism.  Your construction company plans to bid for this business.  You have data on the historical bid frequencies of the average bidder for construction jobs in this area.  These data indicate that, for an average bidder, the proportion of relative bids that exceed a relative bid of 1.05 equals 0.84, and the proportion of relative bids that exceed a relative bid of 1.10 equals 0.70.  However, for one particular competitor – Rockford Construction – you estimate its likelihood of exceeding a relative bid of 1.05 equals 0.65 and its likelihood of exceeding a relative bid of 1.10 equals 0.50. (a)   Briefly describe the concept of expected value.  Then, consider this situation: if the roll of a single die shows a 4, you will win $30, but if it shows any other number, you will win nothing.  Given this situation, what is…

Suppose that you own a used car dealership. You want to sell a 2005 Honda Civic LX. You know that this car is of high quality, and it cost you $5000 to acquire it (so you will not sell it at a price below $5000). However, consumers cannot see the quality of the car at the time of purchase. They believe that 25% of the cars in the used car market are high-quality cars and 75% are low-quality cars or “lemons.” A typical lemon costs $2000 to acquire (so you will not sell it at a price below $2000). Consumers are eager to buy and are willing to pay up to $3000 for a lemon and $6000 for a high-quality car. From now on, suppose that only you (the seller) know the quality of the cars. (Buyers do not know the quality, but know the proportion of high- and low-quality cars in the market). Suppose that you could offer bumper-to-bumper warranties. You know that offering a warranty on a high-quality car costs, on average, $450 per year of warranty offered, while a warranty on a lemon is very…

Consumers are eager to buy and are willing to pay up to $3000 for a lemon and $6000 for a high-quality car. (a) Suppose for a moment that buyers could observe the quality of your car at the time of purchase. At what price would you be able to sell the 2005 Honda Civic Accord LX? If you had a lemon instead, what price would it sell at? (Suppose as a dealer you can induce buyers to pay at their highest willingness to pay. Keep this assumption in all of the following questions.) From now on,…

Exercise 2.2. A three-man board, composed of A, B, and C, has held hearings on a personnel case involving an officer of the company. This officer was scheduled for promotion but, prior to final action on his promotion, he took a decision that cost the company a good deal of money. The question is whether he should be (1) promoted anyway, (2) denied the promotion, or (3) fired. The board has discussed the matter at length and is unable to reach unanimous agreement. In the course of the discussion it has become clear to all three of them that their separate opinions are as follows: • A considers the officer to have been a victim of bad luck, not bad judgment, and wants to go ahead and promote him but, failing that, would keep him rather than fire him. • • B considers the mistake serious enough to bar promotion altogether; he'd prefer to keep the officer, denying promotion, but would rather fire than promote him. C thinks the man ought to be fired but, in terms of personal policy and…

Jackson invested $750 into a savings bond that earned 3% interest each month. At the same time, he also began saving money in a savings account. The value of the savings account is represented by f(x)=1,000+25x, where x represents the Number of months since the account was opened. At the end how many months did the value of the savings bond first begin to exceed the value of the savings account?

Although 23 states barred the self-service sale of gasoline in 1968, most removed the bans by the mid-1970s. By 1992, self-service outlets sold nearly 80% of all US gas, and only New Jersey and Oregon continued to ban self- service sales. Using predictive value for self-service sales for New Jersey and Oregon Johnson and Romeo (2000) estimate that the ban in those two states raised the price by approximately $.03-$.05 per gallon. Why did the ban effect the price? Illustrate using a figure and explain. Show the welfare effects in your figure. Use a table to show who gains or loses.
