Resumen de On the trade, growth, and welfare effects of intellectual property rights protection

Yuki Sato

• To examine how intellectual property rights protection affects trade, growth, and welfare, I develop a two‐country R&D‐based growth model in which final goods firms in both countries determine the range of imported varieties in the overall use of intermediate inputs. I show that strengthening patent protection in either country increases the range of imported varieties of intermediate goods and stimulates economic growth in the country that strengthened patent protection. Moreover, I also show that the Nash equilibrium level of patent protection is stronger than the globally optimal level of patent protection.¡
