Abstract I study the incentive that governments have to protect IPR in a trading world economy, focusing on the patent novelty requirement and its effect on growth an trade. I consider a world economy with ongoing innovation in two regions. The North is assumed to have a higher wage than the...

We consider a world economy with ongoing innovation in two regions. The North is assumed to have a higher wage than the South and...

In this article, we study the possibility to describe several technological regimes with an unique model of semi-endogenous growth based on innovation. Two R&D sectors are modelised: one aims to vertically innovate, another one horizontally. References to alternative litteratures dealing with...
