Effects of Patent Length on R&D: A Quantitative DGE Analysis

Contents:

Author Info

Abstract

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 of the US economy, extending the patent length beyond 20 years leads to a negligible increase in R&D despite equilibrium R&D underinvestment. In contrast, shortening the patent length leads to a significant reduction in R&D and consumption. Finally, this paper also analytically derives and quantifies a dynamic distortionary effect of patent length on capital investment.
