Price is set in a market by a dominant firm price leader (L = Leader).  Total Market Demand is P = 10,000-20*QT.  The dominant firm price leader’s (L = Leader or Dominant Firm) total cost is TCL = 60*QL + 1.5*QL2. The competitive fringe supply (F = Fringe) is SF = PL = 100 + 2QF.  Determine the quantity that will be produced and sold by the Dominant Firm.  The Dominant Firm quantity =

A market has many small firms and one dominant firm. The market demand is Q = 100-5P. The dominant firm has a constant marginal cost of $6. All the smaller fringe firms combined have a supply curve given by Qs = 4P-8. The dominant firm sets the market price, and the fringe firms act as price takers. The dominant firm allows the fringe firms to sell as (Enter your responses many units as they want at the price set by the dominant firm. The rest of the market is then supplied by the dominant firm. The profit-maximizing quantity produced by the dominant firm is units and the price it charges is $ as integers.) The fringe firms will produce and sell a total of units at the market price r your response as an integer.)

Price is set in a market by a dominant firm price leader (L = Leader).  Total Market Demand is P = 10,000-5*QT.QT= 2,000 - .20*P.The dominant firm’s total cost is TCL= 50*QL + 1.5*QL2. The dominant firm’s Quantity Demanded is QL= QT – QF.  The competitive fringe supply isSF= PL = 50 + 2QF;QF = -25 + .5*P. The dominant firm’s profit is _____?

Identify whether each statement is true or false.                                       Market power is the ability of a firm to charge a price greater than marginal cost                                       Most markets are perfectively competitive                                       Charging a price greater than marginal cost leads to maximum economic efficiency                                       In reality, few markets are perfectively competitive

The graph below is for a firm with market power. Place point A at the firm's output and price combination. Place point B at the firm's output and price combination if the government wanted to regulate it and set a price ceiling to restrain its market power and have it produce at the level of a perfectly competitive firm. Then answer the questions.

Feedback Imagine that the flat-screen TV market is made up of one large firm that leads the industry and sets its own price first, and another firm that follows the leader when deciding its own profit-maximizing strategy. The leader has a cost function of c₁ (91) = 5q1, and the follower has a cost function of CF (ar) = 4, where Q =q₁ + qr. Total market demand for flat-screen TVs is given by the function Q = 250.00-2p. Calculate the following values: Leading firm's production: q = Follower firm's production: qp = Equilibrium price: p= $49.37 9 OF 16 QUESTIONS COMPLETED 118.33 32.92 (Round to two decimals if necessary.)

A market consists of a dominant firm and a number of fringe firms. The followings are the information about these firms. Total market demand: QALL=300 – (2.5) P The competitive fringe supply function (total): QF=2P-12 The dominant firms marginal cost function: MC = 12 + (1⁄2) QD.  a) What is the equilibrium price set by the dominant firm?  b) How much will the competitive fringe supply to the market at the price found in question (a)?        Show the answers graphically.
