Under continual innovation, greater patent strength expands innovating firms’ profit against imitation, but also shifts profit from current to past innovators. We show how the impact of patents on innovation, as determined by these two opposing effects, varies with industry characteristics....

We build a growth model with status preference to explore the effects of patent protection on innovation and social welfare. The main results are as follows. There exists a non-monotonic relationship between patent protection and innovation, and the growth-rate-maximizing degree of patent...

This paper theoretically and empirically investigates the effects of patent protection on innovation and economic growth by looking at the interaction between patent system and financial system. On the one hand, patent protection accelerates economic growth through enhancing the value of...

We build a growth model with status preference to explore the effects of patent protection on innovation, inequality and social welfare. The main results are as follows. There is a non-monotonic relationship between patent protection and innovation. In addition, the effect of patent protection...

In this paper, the financial sector is introduced into a directed technological change economic model. The paper shows that, although financial development reduces the incidence of the researcher’s moral hazard, it will not necessarily promote growth. In addition, financial development may...

Under continual innovation, greater patent strength expands innovating firms’ profit against imitation, but also shifts profit from current to past innovators. We show how the impact of patents on innovation, as determined by these two opposing effects, varies with industry characteristics....

This study analyzes how patent protection affects innovation in an R&D-based growth model with elastic labor supply. We find that increasing patent breadth may generate an inverted-U effect on innovation depending on whether the model features the knowledge-driven or lab-equipment innovation...

This study develops a Schumpeterian growth model to analyze the effects of different patent instruments on innovation. We first analyze patent breadth that captures the traditional positive effect of patent rights on innovation. Then, we consider a profit-division rule between entrants and...
