Question:假设公司1和公司2合并。致电新公司A。它具有输出XA和PROUTIDISπa。假设合并后有库诺特竞争。目前，我们假设公司A（合并后的公司）的边际成本仍然为40（与公司3相同）。

e）计算合并后的公司和公司3的数量。此外，计算市场价格和利润。

f）总数量产生（并出售）是否比以前大？

g) Compare the initial sum of profits of the two individual firms, π1 + π2, with the profits of the merged firm, πA. Explain and comment.

If the merged firm were able to exploit economies of scale it would affect costs, maybe even marginal costs. Assume that the marginal cost of the merged firm (only!) was not 40, but 30.

h）合并在这种情况下有利可图吗？与3个公司的原始情况相比，非合并公司（公司3）的利润会发生什么？

i）您能说一下合并公司的MC的减少程度，使合并变得有利可图吗？

j) Relate this to a real-world merger. Are they usually profitable? Can you give examples? Are there other things to consider than marginal cost?

概括：

Questions related to the previous scenario of 3 firms is continued in this answer. The question is that if two firms in the Cornout market merge into one firm, what would the merger result in? how much of marginal cost would prevail in the market, etc are answered in a detailed in manner in the solution.
