In this note, we explore the different implications of patent breadth and R&D subsidies on economic growth and endogenous market structure in a Schumpeterian growth model. We find that these two policy instruments have the same positive effect on economic growth when the model exhibits...

This paper provides a survey on studies that analyze the macroeconomic effects of intellectual property rights (IPR). The first part of this paper introduces different patent-policy instruments and reviews their effects on R&D and economic growth. This part also discusses the distortionary...

To analyze the welfare gain from allowing for differentiated patent protection across sectors, this study develops a two-sector quality-ladder growth model in which patent breadth is a policy variable and derives the optimal patent breadth under two policy regimes. We show that (i) the optimal...

How do intellectual property rights that determine the market power of firms influence the effects of monetary policy on economic growth and social welfare? To analyze this question, we develop a monetary R&D-based growth model with elastic labor supply. We find that monetary expansion reduces...

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...

This study develops an R&D-based growth model with basic and applied research to analyze the growth and welfare effects of two patent instruments (a) the patentability of basic R&D and (b) the division of profi�t between basic and applied researchers. We �find that for the purpose of...

Inspired by the Chinese experience, we develop a Schumpeterian growth model of distance to frontier in which economic growth in the developing country is driven by domestic innovation as well as imitation and transfer of foreign technologies through foreign direct investment. We show that...

This study develops an R&D-based growth model with vertical and horizontal innovation to shed some light on the current debate on whether patent protection stimulates or stifles innovation. We analyze the effects of patent protection in the form of blocking patents. We show that patent...

How does patent policy affect long-run economic growth through the population growth rate? To analyze this question, we develop an R&D-based growth model with endogenous fertility. In recent vintages of R&D-based growth models in which scale effects are absent, the long-run growth rate depends...

This study develops an R&D-based growth model that features both vertical and horizontal innovation to shed some light on the current debate on whether patent protection stimulates or stifles innovation. Specifically, we analyze the growth and welfare effects of patent protection in the form of...
