There is a monopolist, Concrete Mex, in the concrete market in Mexico. The demand function is Qd= 100-50p. The marginal cost of production is c = 0.4. a) ConcreteMex claimed the high price is due to high transportation costs and persuaded the government to help cut down the costs. As a result, for every unit of concrete sold, the government subsidizes ConcreteMex 0.2 dollars. What are the new profit maximizing price and production level for ConcreteMex? b) Under the subsidy policy and the new price in a part, calculate the consumer surplus, producer surplus, and deadweight loss. You do not need to consider government spending for the deadweight loss.  c) Suppose ConcreteMex wants to enter a different market, the competitive market in Texas. To enter the market, ConcreteMex needs to pay a fixed cost of F = 1, and its variable cost in Texas is VC = (0.4+Q)Q. What is ConcreteMex’s total cost, marginal cost, and average total cost in Texas at production level Q?

Assume quantities need not be integers. Assume a profit maximizing monopolist with marginal cost equal to $4 faces demand MWTP(Q) = 14 - 2Q. Assuming it must charge the same price for each unit it sells, what is elasticity of demand at the price it chooses?

A monopolist sells its product in two di§erent countries. The demand in country 1 is Q1 = 50-0.5P1, whereas the demand in country 2 is Q2 = 25-0.25P2. The firm's cost function is C(Q)=10+0.5Q2, where Q = Q1 + Q2.a) Calculate the amount of the product that the profit maximizing monopolist should sell in each country. Q1*=?, Q2*=?b) The determinantal test suggests that the firm's profit function (which one is correct)   is locally concave around the critical point, but not elsewhere   is globally concave   is locally convex around the critical point, but not elsewhere   is globally convex   has a saddle point at the critical point

A monopolist has discovered that the inverse demand function of a person with income Y for the monopolist’s product is P = 0.002Y-Q where P is the price, Y the income, and Q is the output. The monopolist can observe the incomes of its consumers and hence vary its price accordingly. The monopolist has a total cost function C(Q) = 100Q. A. Calculate the profit maximising price as a function of the consumer’s income Y carefully explaining all the steps in the derivation of the formula. B. A monopolist has a constant marginal cost of £2 per unit and no fixed costs. He faces two separate markets in the United States and in the UK. The goods sold in one market are never resold in the other. He sets one price P1 for the US market and another price P2 for the UK market (both measured in £). The demand in the United States is given by Q1=7,000-700P1 and the demand in the UK is given by Q2=1,200-200P1. Calculate the profit maximising output produced and price charged in each country by the…
