You are in the market for a new refrigerator for your company's lounge, and you have narrowed the search down to two models. The energy-efficient model sells for $700 and will save you $45 at the end of each of the next five years in electricity costs. The standard model has features similar to the energy-efficient model but provides no future saving in electricity costs. It is priced at only $500. Assuming your opportunity cost of funds is 6 percent, which refrigerator should you purchase?
1. Alizeh and Kelly were traveling together and have gotten stranded at an airport overnight.
They have no cash, but they did both think to bring granola bars and turkey sandwiches with
them. They currently each have several granola bars and a few sandwiches. Alizeh announces
that she'd be willing to give up a granola bar for one turkey sandwich. Kelly responds that
turkey sandwiches are bigger than granola bars so she would be willing to give up a granola
bar if she could get half a turkey sandwich. Is Kelly and Alizeh's current allocation of granola
bars and turkey sandwiches efficient? Explain why or why not. (Note that you cannot rely
on a rule here – you have to specifically explain why the allocation does or does not meet the
definition of an efficient allocation.)

- If a risk-neutral individual owns a home worth $200,000 and there is a three percent chance the home will be destroyed by fire in the next year, then we know 15. that: a) He is willing to pay much more than $6,000 for full cover. b) He is willing to pay much less than $6,000 for full cover. c) He is willing to pay at most $6,000 for full cover. d) None of the above are correct. e) All of the above are correct.arrow_forwardAnderson is facing the hardest decision in his life: Should he buy the newest Xbox Series X (cost $500), the newest Apple Airpod Max (cost $550), or the newest Apple Mac Pro Wheels Kit (cost $700). Right now, Anderson has exactly $700. Provided that Anderson already has EVERYTHING he needs and the $700 cannot be used on anything else to make him happier (in other words, the $700 should only be spent on these 3 items. Moreover, for example, if Anderson chooses to buy the Xbox for $500, the remaining $200 is not usable and has no value to Anderson). 1/ If Anderson chooses to buy the Airpod Max, what is the opportunity cost associated with that option? 2/ How would your answer in 1/ change if Anderson just won the $1 million lotteries today? 3/ How would your answer in 1/ change if Anderson just lost one of his $100 bill today, making him now only has $600 left?arrow_forward3) Marco has $100 worth of grain in period 1 but gets no grain in period 2. Marco has two choices. He can store the grain that he does not consume in period 1. This results in a loss of 20% of the grain due to pests. Assume that with this option he will choose to consume 68 units of grain in period 1 and 26 units in period 2. Instead, Marco can sell the grain he does not consume in period 1 and lend the money from that sale to someone today at an interest rate of 10%. He can then use the repayment of that loan to buy gain in period 2. a) Based on this information, draw a diagram that outlines Marco's choices. Is he definitely better off once the opportunity to lend is available to him? b) Relative to his initial equilibrium point, does he unambiguously consume more in both periods once he can lend out the excess he does not consume in period 1? c) Now assume that Marco can sell any excess grain he doesn't consume in period 1 and invest the money he gets in a new type of risky activity.…arrow_forward
- 8. Suppose that you have a big test on Monday and you plan to spend the weekend studying. On Saturday, your friend invites you to spend the day at a water park. It's the last weekend that the park will be open for the year. You'd really like to go to the park, but you're worried that you won't have enough time to study on Sunday. What are the possible tradeoffs of each choice-going to the water park or staying home to study?arrow_forwardMing lives in Seattle and recently bought a $125 ticket to attend a Seattle Seahawks game. He is a huge fan, so even though the ticket is pricey it is well below his willingness to pay of $250 However, as game day approaches, Ming receives an invitation from his friend, Cassandra, to spend the day at the Museum of Pop Culture touring a big exhibit on Marvel superheroes. The museum visit would only cost $75, but Ming (being a big Marvel fan too) would be willing to pay $150. What is his opportunity cost of going to the Seattle Seahawks game? Ming's total opportunity cost of going to the Seattle Seahawks game is $ (Enter a numeric response using an integer)arrow_forwardEvery week I spend a total of £400 buying two goods, luxuries (L) and necessities (N). I obtain utility (U) from these goods according to the rule U(L, N) = 10 + L + 20N−2N2. Suppose that I pay £10 for each unit of L and £20 for each unit of N and that I am a utility-maximiser. MUL=1 and MUN=20-4N. Define the Marginal Rate of Substitution (MRS) as MRS ≡ MUL/MUN). Calculate its value at the bundle (L = 0 and N = 4) and at (L = 1 and N = 4). By referring to a graphic illustration of the above calculations or otherwise, argue that an increase in my budget will have no effect on my consumption of N if I am already consuming 2.5 units of N. Calculate my optimum choice of L and N if instead I have £40 to spend. Fully explain your answer.arrow_forward

For a fixed annual fee (paid in advance) one can purchase goods at 90% of their listed price (in other words, 10% off the list price); otherwise, one pays the list price. Suppose that the annual fee is $300 and the interest rate on your savings account is 5%. Finally, assume discount club's list prices are the same as any other store, and you plan to spend $4000 over the coming year at this store. (Hint: the interest represents an opportunity cost of purchasing a membership). benefit not buying is a membership I dollars and the cost of not buying The of a membership is dollars.

At every time step, there is a demand for energy in the home which is drawn from 0,1,2 units with equal probability independent of the demands in the previous time steps. At every point in time, you have to satisfy the demand either by discharging the needed energy from the battery or purchasing power from the grid (or a combination of the two). You could also choose to purchase power from the grid to charge your battery. The grid energy price is either H(igh) or L(ow) according to a Markov chain (Price moves from H to L with probability p, and from L to H with probability q). (a) Model the decision making as an infinite horizon MDP where the objective is to minimize the discounted cost of energy purchased over an infinite horizon. (b) Write down a policy a of your choosing. Perform two steps of the operator T, for your policy, followed by one step of T..arrow_forward
- 6) You have been assigned to create a new TV game show, and you have an interesting idea that you call, “I WANT TO BE A MILLIONAIRE.” The basics are: 1) two contestants; 2) the show begins with each contestant being given $1 million (!); and then 3) they begin playing a game that can increase or decrease that $1 million. You worry that the initial outlay of $2 million will stun your producers, so you decide to prepare them with a simpler version of your game that you call: “I WANT $3.” There are four steps in this simpler game: There are two contestants/opponents (who do not know each other and cannot communicate with each other during the game). Each player is given $3 at the start of the game. Independently and simultaneously, each player must choose whether they want to add $0, $1, $2 or $3 to their initial stake of $3. Doing so reduces their opponent’s award by $0, $2, $4, or $6, respectively. Each player knows that their payoff at the end of the game is based on their initial…arrow_forwardAhmed is considering his plans for the coming weekend. He is currently working as a marketing specialist in a big advertising company. He normally spends the weekend with family but this weekend he is thinking of going on a camping trip that would cost him about $1,900. At the same time, his manager asked him whether he can help during the weekend and the company will be willing to pay him an overtime bonus of $1,000. If Ahmed goes on the camping trip, he can manage to provide a number of quick consultancy services that would earn him around $2,500. If Ahmed decided to go on the camping trip what would be the incremental cost of that decision ($)? a.

Ahmed has had this position for several years, but recently Ahmedhas developed a cocaine habit. He recently sold one of Bader’s cars and kept some of the money himself to buy some cocaine. Soon thereafter, Ahmed was declared bankrupt. The government then notified Ahmed that he had sold the maximum allowable number of cars in a year without getting a dealer’s license. Shortly thereafter, Bader was on a secluded island and died, which no one knew about until 2 weeks later. Discuss the effect of these events on the existence of the agency.arrow_forward
