What is an example of a firm which, one might argue, is experiencing either (a) economies of scale, or alternatively (b) diseconomies of scale. What are the advantages or disadvantages the firm in question seems to receive when its scale of operations increases, what are the effects of these things, and why do you think they occur? Make sure you are explicit in your answer about the time period (short term or long term) during which economies or diseconomies of scale appear, explain what economies or diseconomies of scale are, and suggest a reason why one or another of them might be occurring.
