| Tiivistelmä: | In this article, the impact of retail mergers (hereafter as: mrg./mrgs.) on product variety (here as: p-v.) is analyzed. It is shown that after a mrg., a retailer (as: r-tr.) may want to enhance its buyer power by committing to a 'single-sourcing' purchasing strategy. Anticipating further industry concentration, suppliers will strategically choose to produce less differentiated products, further reducing p-v. In the case of efficient negotiations, the overall loss in p-v. may reduce consumer surplus and total welfare. However, with linear tariffs there may be a countervailing effect with the more powerful r-tr. passing on lower prices to final consumers. |
