In an auction, potential buyers compete for a good by submitting bids. Adam Gallinsky, a social scientist from NWU, compared eBay auctions in which the same good was sold. He found on average that, the higher the number of bidders the higher the sales price. For example, in two separate auctions of identical IPods, the one with the higher number of bidders brought the higher sales price. According to Gallinsky, this explains why smart sellers set absurdly low opening prices (the lowest price the seller will accept), such as 1 cent for a new IPod. Use the concept of consumer and producer surplus to explain this reasoning.

Praxilla, who lived in ancient Greece, derives utility from reading poems and from eating cucumbers. Praxilla gets 30 units of marginal utility from her first poem 27 units of marginal utility from her second poem 24 units of marginal utility from her third poem, and so on, with marginal utility declining by three units for each additional poem. Praxilla gets six units of marginal utility for each of her next three cucumbers consumed, five units of marginal utility for each of her next three cucumbers consumed, four units of marginal utility for each of the following three cucumbers consumed, and so on, with marginal utility declining by one for every three cucumber consumed. A poem costs three bronze coins hut a cucumber costs only one bronze coin. Praxilla has 18 bronze coins. Sketch Praxillas budget set between poems and cucumbers, placing poems on the vertical axis and cucumbers on the horizontal axis. Start off with the choice of zero poems and 18 cucumbers, and calculate the changes in marginal utility of moving along the budget line to the next choice of one poem and 15 cucumbers. Using this step-by-step process based on marginal utility, create a table and identify Praxillas utilityâ€”maximizing choice. Compare the marginal utility of the two goods and the relative prices at the optimal choice to see if the expected relationship holds. Hint: Label the table columns: 1) Choice, 2} Marginal Gain from More Poems, 3) Marginal Loss from Fewer Cucumbers, 4) Overall Gain or Loss, 5) Is the previous choice Optimal? Label the table rows: 1) 0 Poems and 18 Cucumbers, 2) 1 Poem and 15 cucumbers, 3) 2 Poems and 12 cucumbers, 4) 3 Poems and 9 Cucumbers, 5) 4 Poems and 6 cucumbers 6) 5 Poems and 3 Cucumbers, 7) 6 Poems and 0 Cucumbers.
You'd like to study social networks. Consider the following 7 people {A,B,C,D,E,F,G} in a social network graph. (These people can be thought of as "nodes" or points drawn on a piece of paper.) Here, we'd like to model "followers." How many different ways can we draw arrows between two people from these 7? Here, "A-->B" (A is a follower of B) is not the same as "B-->A" (B is a follower of A). Order matters here
Define the Nash Equilibrium. Give examples.
Adam Smith from the Classical School had introduced the “water-diamond paradox” in his Theory of Value. But he did not solve the paradox because he failed to understand the concept of utility. Explain by demonstrating relevant graph how this paradox was solved by William Stanley Jevons from the Marginalist School by using law of diminishing marginal utility.
Suppose the utility possibility frontier for two individuals is given by U_a+2U_b=200 Please plot the utility frontier on a graph.

In the movie Rebel Without a Cause, James Dean and Buzz Gunderson compete for thefavours of sixteen year old Judy. Buzz's gang members steal two cars. The group of teenagers gathers on aLos Angeles lookout, with a cliff that drops down to the Pacific Ocean. James and Buzz are to drive the stolencars toward the cliff. The first person to jump from his car is declared the chicken (which is bad). The lastperson to jump is the hero (which is good), capturing Judy's affection and the gang's respect. The driverlesscars continue over the cliff and plunge to the rocks at its base.Each driver can make two possible actions. Jump when he feels endangered (be a chicken) or jump AFTERthe other driver jumps (be a rooster). Assuming that both feel endangered at the same moment, the followingmatrix represents the payoffs for James and Buzz for each choice of strategy.BuzzChicken RoosterJames Chicken 3, 3 -10, 20Rooster 20, -10 -50, -50 PLEASE ANSWER THE BELOW QUESTION WITH REFERECE TO THE ABOVE…
u work for a marketing firm that has just landed a contract with Run-of-the-Mills to help them promote three of their products: splishy splashies, flopsicles, and mookies. All of these products have been on the market for some time, but, to entice better sales, Run-of-the-Mills wants to try a new advertisement that will market two of the products that consumers will likely consume together. As a former economics student, you know that complements are typically consumed together while substitutes can take the place of other goods. Run-of-the-Mills provides your marketing firm with the following data: When the price of splishy splashies increases by 4%, the quantity of flopsicles sold increases by 1% and the quantity of mookies sold decreases by 5%. Your job is to use the cross-price elasticity between splishy splashies and the other goods to determine which goods your marketing firm should advertise together. Complete the first column of the following table by computing the…

Burger King has introduced new strategy by reducing the price of its Whopper by 75 percent if customers also purchased french fries and a soft drink. Nevertheless, the sales dropped within two weeks. Based on your knowledge on game theory, what do you think had happened? The Edge magazine columnist, Jack Sparrow reported the recent findings of two academic political scientists. These scholars found out that voters are not happy with “negative campaigns” of politicians. However, the political scientists suggested it is pointless for candidates to stay positive. The damage from staying positive is heaviest when the opponent is attacking. Explain the dilemma. Airlines practice price discrimination by charging leisure travelers and business travelers different prices. Why do you think by charging different prices; the airline companies will maximize their profits? Discuss briefly.
In today’s economy, it’s harder for workers to get promoted. In 2006, it took an averageof 2 ½ years to get a promotion; today it takes 4 ½ years. As a result, fewer workers are willingto boost their productivity in an effort to impress the boss and get the promotion. In 2006, 25percent of employees said they were willing to give “an extra oomph” at work (boost theirproductivity); today about 15 percent are willing to do so. Explain the connection to the Phillipscurve.
