We develop a Schumpeterian growth model to analyze the interaction between patent policy and firms’ internal strategies … to capture value from innovations. We consider two dimensions of patent policy: backward protection against imitation and … forward protection, also known as blocking patents, against subsequent innovation that builds on a patented technology …

We analyze the use of patent protection as a new policy to direct technical change to clean technology. Contrary to … popular belief, it is dirty (and not clean) innovations that should be excluded from patent protection to reduce emissions. In … the shortrun, removing patent protection on dirty technology increases emissions. However, the reduced markup on dirty …

product (or "downstream") sector. Innovation takes place in both sectors. Following Gilbert and Shapiro (1990), we define … patent breadth as the ability of the innovator to reap profits as a result of the patent protection. Greater patent breadth … in the downstream sector increases the incentives of agents to do R&D in that sector but discourages innovation in the …

capital is positively influenced by the size of the R&D sector, sheds new light on innovation and growth as well as income …

The importance of knowledge spillovers for achieving innovation and economic growth is widely recognized. It is not … this controversy using a model of regional growth. The model also deals with the impact of local competition on innovation …
