Abstract
In a world where poor countries provide weak protection for intellectual
property rights, market integration will systematically shift technical change
in favor of rich nations. For this reason, free trade can increase international
income differences. At the same time, integration with countries where intellec-
tual property rights are weakly protected can have a large adverse effect on the
world growth rate. These results provide a strong rationale for global regula-
tions, critical in a system of interdependent economies for sustaining innovation
and reducing income inequality. Supportive empirical evidence is presented.
