摘要:本文中对一系列经济营销课程的专业问答进行了详细的解答,供大家参考。
Question 1,
Assume that two companies (C and D) are duopolists that produce identical products. Demand for the products is given by the following linear demand function:
P = 600 – QC - QD
Where QC and QD are the quantities sold by the respective firms and P is the selling price. Total cost functions for the two companies are
TCC = 25,000+100 QC
TCD = 20,000+125 QD
Assume that the firms act independently as in the Cournot model (i.e., each firm assumes that the other firm’s output will not change)
a. Determine the long-run equilibrium output and selling price for each firm
b. Determine the total profits for each firm at the equilibrium output found in Part (a)
Question 2,
Assume that two companies (A and B) are duopolists who produce indentical products. Demand for the products is given by the following linear demand function:
P = 200 – QA – QB
Where QA and QB are the quantities sold by the respective firms and P is the selling price. Total cost functions for the two companies are
TCA = 1,500+55 QA + QA2
TCB = 1,200+ 20 QB + QB2
Assume that the firms act independently as in the Cournot model (i.e., each firm assumes that the other firm’s output will not change)
a. Determine the long-run equilibrium output and selling price for each firm
b. Determine Firm A, Firm B and industry profits at the equilibrium solution found in Part (a)
Question 3,
Consider Exercise 2 again. Assume that the firms form a cartel to act as a monopolist and maximize total industry profits (sum of Firm A and Firm B profits).
a. Determine the optimum output and selling price for each firm
b. Determine Firm A, Firm B and industry profits at the equilibrium solution found in Part (a).
c. Show that the marginal costs of the two firms are equal at the optimal solution found in Part (a).
Question 4,
Compare the optimal solutions obtained in Exercises 2 and 3. Specifically:
a. How much higher (lower) is the optimal selling price when the two firms form a cartel to maximize industry profits, compared to then they act independently?
b. How much higher (lower) is total industry output
c. How much higher (lower) are total industry profits.
Question 5,
Suppose that two Jananes companies, Hitachi and Toshiba, are the sole producers (i. e., duopolists) of a microprocessor chip used in a number of different brands of personal computers. Assume that total demand for the chips is fixed and that each firm charges the same price for the chips. Each firm’s market share and profits are a function of the magnitude of the promotional campaign used to promote its version of the chip. Also assume that only two strategies are available to each firm: a limited promotional campaign (budget) and an extensive promotional campaign (budget). If the two foirms engage in a limited promotional campaign, each firm will earn a quarterly profit of $7.5 million. If the two firms undertake an extensive promotional campaign, each firm will earn a quarterly profit of $5.0 million. With this stratege combination, market share and total sales will be the same as for a limited promotional campaign, but promotional costs will be higher and hence profits will be lower. If eother firm engages in a limited promotional ca本论文由英语论文网提供整理,提供论文代写,英语论文代写,代写论文,代写英语论文,代写留学生论文,代写英文论文,留学生论文代写相关核心关键词搜索。
