Abstract: | This paper investigates two stylised facts about quality wars between Northern firms and a Southern copycat firm in the North. First, due to low wage, a foreign or Southern copycat firm may enter the market of a developed economy inhabited by a high‐quality firm and a low‐quality domestic copycat. When the products of the high‐quality firm and the foreign copycat are vertically differentiated, the foreign copycat firm may choose an intermediate quality between the quality levels of domestic high‐ and low‐quality firms. In the second scenario where the products of the high‐quality firm and the foreign copycat are horizontally differentiated, the quality of the foreign copycat may surpass that of the domestic high‐quality firm. As the wage gap between the developed and developing countries widens, the foreign copycat is more likely to survive in the markets of developed economies. |
