| Abstract: |
To investigate whether intellectual property rights (IPRs) promote or hinder
seed technology diffusion through trade, we use panel data for 134 countries
over the period 1985-2010 to evaluate the impact of a country’s IPRs on its
seed imports from the U.S. by estimating a gravity equation using both linear
and nonlinear (Poisson) fixed effects methods. In both the static and dynamic
models, the variable for WTO member countries that have implemented the TRIPs
(Trade-Related Aspects of Intellectual Property Rights) agreement consistently
shows a significantly positive effect on seed imports. We improve on previous
studies by focusing on one type of planting seeds - field crop seeds, also
accounting for status of growing genetically modified crops, and utilizing an
estimation technique (Poisson) that is more viable in the handling of zero
trade observations. |
