Suppose three Cournot competitors, each with costs Ci = 30qi, face an inverse market demand curve of P = 480 – 4Q. Suppose merging will not change costs. a. Find profits for the three firms. Note:  Don’t round your answers.  How will the profits change for F1 and for F2|3 if F2 and F3 merge? b. Suppose that after the merger occurs, F1 and the new firm F2|3 successfully collude at setting the monopoly price and output, and splitting the resulting monopoly profits. How, if at all, does this change the impact of the merger on F1 and on the merged firm?
