A simple model of quality heterogeneity and international trade

  • Dinopoulos, Elias
  • Unel, Bulent

This paper develops a trade model with firm-specific quality heterogeneity in markets where firms face the threat of imitation and engage in limit-pricing strategies. Firms producing high-quality (high-price) products export, whereas firms producing lower-quality (lower-price) products serve the domestic market. Trade liberalization raises the average domestic markup and increases the number of products consumed in each country. However, the impact of trade liberalization on the average export markup depends on the nature of liberalization. Although the presence of markups renders the laissez-faire equilibrium suboptimal, trade liberalization increases national and global welfare.
