- Be fast Suppose there are three (3) consumers in a market for bottles of perfume; Mutumbu, Jasanu and Julius The individual demand for perfumes for each of these consumers is given as 10 bottles for Mutumbu, 15 bottles for Jasanu and 25 bottles for Julius at $60 per bottle for perfume. Thus, the market demand for perfumes if the market price is $60 is: (a)40 bottles (b)60 bottles (c)80 bottles (d) None of the aboveMarket Equilibrium A retail chain will buy 900 cordless phones if the price is $10 each and 400 if theprice is $60. A wholesaler will supply 700 phonesat $30 each and 1400 at $50 each. Assuming that thesupply and demand functions are linear, find the market equilibrium point and explain what it means.Consider the market for lattes What would happen to the equilibrium price and quantity of lattes if the cost of milk, which is used to make lattes, falls?

- To obtain the market demand curve for a product, sum the individual demand curves .................a) diagonallyb) verticallyc) and then average themd) horizontallyThe following relations describe monthly demand and supply for a computer support service catering to small businesses.Q D = 3,000 - 10PQ S = -1,000 + 10Pwhere Q is the number of businesses that need services and P is the monthly fee, in dollars.a. At what average monthly fee would demand equal zero?b. At what average monthly fee would supply equal zero?c. Plot the supply and demand curves.d. What is the equilibrium price/output level?e. Suppose demand increases and leads to a new demand curve:Consider a “market” with differently substitute goods. Firms1 and 2 produce homogeneous goods, but firm 3 produces a differentiated (imperfectly substitute) good. Thus, the inverse demand functions for each of the firms are:P1 = 1 − 2q1 − 2q2− .5q3P2 = 1 − 2q2 − 2q1− .5q3P3 = 1 − 2q3 − .5q1− .5q2All firms have zero costs. They compete in quantities. We want to study this “market” to define a relevant market as traditionally done by antitrust agencies, and to that end we are going to perform the SSNIP test. The question is whether the product offered by firm 3 is in the same “market” as that offered by firms 1 and 2. Thus, we need to know if a “hypothetical” monopoly (or cartel) producing goods 1 and 2 would increase the price by a 5-10% at least. Thus, (a) let us first compute the prices in this “market” as it is. (You can use symmetry between firms 1 and 2, so that you expect q1 = q2, to speed up the computation of equilibrium outputs and prices.) b) Now consider a hypothetical…
