This study develops a research and development (R&D)–based growth model with basic and applied research to analyze the growth and welfare effects of two patent instruments: (i) the patentability of basic R&D and (ii) the division of profit between basic and applied researchers. We find that...

This paper develops an R&D-growth model and calibrates the model to aggregate data of the US economy to quantify a structural relationship between patent length, R&D and consumption. Under parameter values that match the empirical flow-profit depreciation rate of patents and other key features...

To analyze the effects of patent policy on growth and inequality, this article develops a qualityladder model with wealth heterogeneity and elastic labor supply. The model predicts that strengthening patent protection increases (a) economic growth by stimulating spending on research and...

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...

In a generalized quality-ladder growth model, this paper firstly derives the optimal patent breadth and the socially optimal profit-sharing arrangement between patentholders. In this general-equilibrium setting, it identifies and derives a dynamic distortion of markup pricing on capital...

Is the patent length an effective policy instrument in stimulating R&D? This paper develops a generalized variety-expanding growth model and then calibrates the model to the aggregate data of the US economy to analyze the effects of extending the patent length. The numerical exercise suggests...

What are the effects of strengthening patent protection on income and consumption inequality? To analyze this question, this paper incorporates heterogeneity in the initial wealth of households into a canonical quality-ladder growth model with endogenous labor supply. In this model, I firstly...

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...

This paper develops an R&D-growth model and calibrates the model to aggregate data of the US economy to quantify a structural relation ship between patent length, R&D and consumption. Under parameter values that match the empirical flow-profit depreciation rate of patents and other key features...
