Abstract: In this paper we exploit firm-level data on patent grants and subsequent reactions of their stocks to identify technological news shocks. Changes in stock market valuations due to announcements of individual patent grants represent expected future increases in the technology level, which we refer to as patent-based news shocks. Our patent-based news shocks resemble diffusion news in that they do not affect total factor productivity in the short-run but account for about 20 percent of its variations after five years. These shocks induce positive comovement between consumption, output, investment and hours. Unlike the existing empirical evidence, patent-based news shocks generate a positive response in inflation and the federal funds rate, in line with a standard New Keynesian model. Patenting activity in electronic and electrical equipment industries within the manufacturing sector and computer programming and data processing services within the services sector play a crucial role in driving our results.
