Intellectual Property Rights and Economic Growth
The authors investigate the impact of Intellectual Property Rights (IPR) protection on economic growth in a panel of 79 countries using threshold regression analysis. We show that whilst the effect of IPR protection on growth depends upon the level of development, it is positively and significantly related to growth for low- and high-income countries, but not for middle-income countries. This suggests that, although IPR protection encourages innovation in high-income countries, and technology flows to low-income countries, middle-income countries may have offsetting losses from reduced scope for imitation.
