Mergers and Malls
研究了销售互补产品（如购物中心内的店铺）的企业集团之间的竞争，发现集团内的企业往往更愿意保持独立而非合并。
This paper examines competition between groups of firms selling products that are complementary within the group but substitutes across groups. Examples include shops within different malls and components of different computer systems. It shows that firms within a group will often prefer to stay as separate companies rather than merge.
