We find that more patent-intensive industries responded to stronger patent laws with higher growth, which effect increased with GDP per capita. Between 1991-1995, an increase in the level of effective patent rights from Hong Kong to Australia would have raised the average growth of the leather industry by 1/18, but that of the other chemicals industry by about 1/5. Patent rights increased growth through both factor accumulation and raising productivity. Our findings were robust to alternative measures of patent rights and patent intensity
