Consider the situation where oligopolists collude in a market to maximise their potential prot. Suppose the following chart shows the costIrevenue structure the oligopolists in this market face. 'ATC '\"\"'\"\"1ooizpoiaoofaoofspo?\"z (a) Identify the prot maximising price and output level for this oligopoly. Calculate the prot or loss that is being made in this market. (4 marks) (b) Is the prot or loss you calculated in Part (a) sustainable in the long run? Briey explain why or why not. (3 marks) (c) Briey compare an oligopoly market structure with that of monopoly. Does the monopolist face different costfreyenue curves to those shown in the chart. or are they the same? (3 marks) (Approximate numbers read off the chart are ok.)
