| Abstract: | A firm that offers an additional product can capture business from rival firms fro other products when consumers prefer to concentrate their purchases at a single supplier. This may lead firms to offer excessive product variety from the social standpoint. A firm may even completely foreclose competing firms from the market by introducing a new product. Forbidding new product introductions, forbidding mergers that broaden firms' product lines, and forbidding Sunday shopping may sometimes be appropriate public policies. |
