- Suppose a town is planning to construct a new public park. Based on some market research, they have determined that the town’s 50 residents can be divided into two types with respect to their benefit from this public good. 20 of the town’s residents are of Type 1 and the other 30 residents are of Type 2. Each resident's individual demand for acres of park space is given by: Type 1: QD = 20 – P Type 2: QD = 40 – 2P a. Solve for the aggregate demand of the towns 50 residents as a function of the number of acres. Be sure to write down equations for each section of the aggregate demand curve, as well as the interval of quantities each section spans. b. Graph the aggregate demand curve calculated in part a. Make sure to label both intercepts, slopes, and the intersection of the two sections.6. If the demand equation is L=100-10r find the consumer's surplus when the consumer purchases 8 units.Refer to the diagram. Between prices of $5.70 and $6.30: A. D1 is more elastic than D2 B. D2 is an inferior good and D1 is a normal good. C. D1 and D2 have identical elasticities. D. D2 is more elastic than D1
- First suppose the market demand for “cougar caps” is given by the equation: Q = a1 + a2 * P - a3 * P2 + a4*I where P is the price of cougar caps, I is income, Q is quantity of cougar caps and a1, a2, a3, a4 are positive constants. What is the price elasticity of demand? What conditions need to hold for this to be an elastic demand? An inelastic demand? What is the income elasticity? What conditions are needed for this to be a normal good ? Inferior?There are two restaurants next to each other. Restaurant 1 (R1) sells burritos and Restaurant 2 (R2) sells burgers. Both restaurants have to simultaneously set their prices which can be any non-negative 1 real number. Denote by p1 the price of a burrito set by R1 and by p2 the price of a burger set by R2. Since consumers have a choice of which restaurant to go to and are price conscious, the price of each restaurant, besides impacting the demand for its own product, effects the demand for the product of the other restaurant as well. Specifically, the demand functions for the burritos sold by R1 and burgers sold by R2, denoted q1 and q2, respectively, are given by: q1 = 44 − 2p1 + p2 q2 = 44 − 2p2 + p1 (For simplicity, we are assuming here that demand is perfectly divisible). Finally, the cost of producing each unit of burger and burrito is the same and equal to 8. Model this strategic environment as a normal form game and find a pure strategy Nash equilibrium. Is the equilibrium you…Suppose there are only two fishermen, Maria and Ruby, who fish along a certain coast. They would each benefit if lighthouses were built along the coast where they fish. The marginal cost of building each additional lighthouse is $100. Maria’s demand curve for lighthouses is given by P=170-2Q, and Ruby’s by P=150-Q, where Q is the number of lighthouses. Explain why we might not expect to find the efficient number of lighthouses along this coast. Draw the demand curve for Maria and Ruby individually and the market demand for lighthouses. What is the efficient number of lighthouses?

Suppose there are network externalities in this market such that the quantity of a good demanded grows in response to the growth of purchases by other individuals (as indicated by the demand curve "Demand" in the figure). Suppose that the price is initially $90 where the quantity demanded is 120 (thousand CD players per month). If the price of CD players falls to $50, demand will increase to 180 thousand CD players per month. (Enter your response using an integer.) Of this increase, price effect and thousand units of the 60 thousand-unit increase is the pure thousand units of the increase is the bandwagon effect.

The market price of each electric vehicle is $200,000, and each consumer demands no more than one electric vehicle. Suppose that Jake is the only consumer in the electric vehicle market. Their willingness to pay for an electric vehicle is $350,000. Based on Jake's willingness to pay, the following graph shows his demand curve for electric vehicles. Shade the area representing Jake's consumer surplus using the green rectangle (triangle symbols).
