(20 marks) Suppose the market for disposable gloves is competitive and it is originally operating at the long run equilibrium. An important raw material of producing disposable gloves is natural rubber. Suppose there is a drastic increase in the price of natural rubber. With the aid of side-by-side diagrams, explain the impacts of the above change on the equilibrium price and equilibrium quantity in the market for disposable gloves, as well as the profit maximizing output level of a typical...
(a) A firm has a total cost schedule of TC = 10 – 3q + 12q2. Draw a sketch graph of the total cost function showing all important points. (b) Assuming that the quantity sold is greater than 2 units (q > 2), at what output level will TC = £200?

Show your steps. iii) Find the amount of loss...
Suppose a firm faces a total cost function of: T C(Q) = 55 − 2Q + 10Q 2 (a) How would you express the average fixed cost for any level of output? What is the average fixed cost for 5 units of output? (b) How would you express the variable costs? What are variable costs when output is 6? (c) What is the marginal cost for the 12th unit of output? (d) At what level of output do marginal costs...
Suppose a pharmaceutical firm just invents a new drug to treat mad cow disease and this is the only effective drug available in the market. The demand and total cost functions of the firm are: Demand: P = 36 – Q Total cost: C = 24 + 2Q2 where P is the price of the drug, Q is the quantity of the drug and C is the total cost of the firm. a. Find the marginal cost and marginal revenue...

Problem 3 [24 marks] A competitive firm uses two inputs, capital (k) and labour (), to produce one output, (y). The price of capital, W, is S1 per unit and the price of labor, wi, is SI per unit. The firm operates in competitive markets for outputs and inputs, so takes the prices as given. The production function is f(k,l) 3k025/025. The maximum amount of output produced for a givern amount of inputs is y(k, l)...
