a) Some consumers strongly prefer Coke and some strongly prefer Pepsi. Statement: this means that Coke and Pepsi are not in the same market. b) Consider a Cournot duopoly: demand is P(91, 92)=40-91-92, marginal costs are constant at c = 10 for both firms. Statement: for any player, choosing a quantity q, = 12 is a dominated strategy. (c) Consider an oligopoly. Suppose that one of the firms has the option to move before its opponents (instead of the firms deciding simultaneously). Statement: the firm will never strictly prefer to forgo this option. d) It is optimal for a monopolist to choose a quantity such that ea < 1. (e) The elasticity of demand for petrol is d = -2.4. The price of petrol is £5 per gallon and sales are 1 million gallons (per month). Statement: if the price of petrol falls by 1 percent, sales revenue will fall.
