Consider the market for a good that has 7 buyers. Each buyer has the same income $I. Let q denote the amount of the good and m the money left after buying the good. Buyers 1,2 have the same utility function u1 = 8q − q 2 + m. Buyers 3,4,5 have the same utility function u3 = 10q − q 2 + m. Buyers 6,7 have the same utility function u6 = 16q − q 2 + m. Denote the price of the good by p. (a) [5 points] Note that each buyer has the same income $I. Determine I should be at least how large to ensure that for every buyer, the income $I is adequate to purchase its desired amount of the good at any price p. For (b)-(c), assume income $I is such that for every buyer, the income is adequate to purchase its desired amount of the good at any price p. (b) [5 points] Solving utility maximization problem, for each buyer find the individual demand. (c) [4 points] Determine the numerical values of the market demand Q for the following prices: (i) p = 9, (ii) p = 13.

5. There are five buyers and five sellers in a perfectly competitive market. Each buyer wishes to purchase one single unit of the good. The willingness to pay displayed by these buyers is presented in the following table: Buyer: 1 2 3 4 5 Willingness to Pay: $4 $8 $2 $5 $7 Each firm sells also only one unit of the good. The cost of producing that unit for these firms is denoted by the following table: Seller: 1 2...

There is single object to be sold to one of the n potential buyers. Each buyer has a valuation of vi for the object. Consider the auction rule where the winner is the highest bidder, and pays the minimum of all the bids, i.e. min{bi : i ∈ N}. In this game, truthtelling is a dominant strategy equilibrium. Is it true or false ?

A market consists of groups of buyers and sellers of a good or service. Market equilibrium represents the price at which the quantity of goods supplied is balanced with the quantity of goods consumers are willing and able to buy. Consider the market for iPads. What could change the quantity of iPads consumers are willing and able to purchase? Identify examples of three events since 2010 that have caused changes in the iPad market's equilibrium. For each event, decide whether...

Consider a market in which there are many potential buyers and sellers of used cars. Each potential seller has one car, which is either of high quality (a plum) or low quality (a lemon). A seller with a low-quality car is willing to sell it for $4,500, whereas a seller with a high-quality car is willing to sell it for $8,500. A buyer is willing to pay $5,500 for a low-quality car and $10,500 for a high-quality car. Of course,...

Suppose the incomes of buyers in a market for a particular normal good decrease and there is also a reduction in input prices. Graphically show what happens to the demand and supply curve, and comment on what would happen to the equilibrium price and quantity in this market. Please label all parts of your graph to receive full points.
