7. Based only on the knowledge that the premerger market share of two firms proposing to merge was 20 percent each, an economist working for the Justice Department was able to determine that, if approved, the postmerger HHI would increase by 800. How was the economist able to draw this conclusion without knowledge of the other firms' market shares? From this information, can you devise a general rule explaining how the Herfindahl-Hirschman index is affected when exactly two firms in the market merge? (Hint: Compare a + with (a + b)².)
While there is a degree of differentiation between major grocery chains like Albertsons and Kroger, theregular offering of sale prices by both firms for many of their products provides evidence that these firmsengage in price competition. For markets where Albertsons and Kroger are the dominant grocers, thissuggests that these two stores simultaneously announce one of two prices for a given product: a regularprice or a sale price. Suppose that when one firm announces the sale price and the other announces theregular price for a particular product, the firm announcing the sale price attracts 1000 extra customers toearn a profit of $5000, compared to the $3000 earned by the firm announcing the regular price. Whenboth firms announced the sale price, the two firms split the market equally (each getting an extra 500customers) to earn profits of $2000 each. When both firms announced the regular price, each companyattracts only its 1500 loyal customers and the firms each earned $4500 in…
