This paper introduces dynamics in the R&D to innovation and innovation to productivity relationships, which have mostly … individual effects and idiosyncratic errors correlated across equations and that differ in the way innovation enters the … Community Innovation Survey. The results provide evidence of robust unidirectional causality from innovation to productivity and …

received over their careers, and employed to highlight the implications of patent institutions for markets in inventions and … for democratization. The United States deliberately created a patent system that differed from existing European systems … in ways that significantly affected the course of technological change. Patent rights in the U.S. helped to define and …

Encouraging inventors to disclose new inventions is an important economic justification for the patent system, yet the … technical information contained in patent applications is often inadequate and unclear. This paper proposes a novel approach to … measure disclosure in patent applications using algorithms from computation allinguistics. Borrowing methods from the …

We construct a tractable general equilibrium model of cumulative innovation and growth, in which new ideas strictly … lower than the social planner's benchmark, which suggests a role for patent policy. We focus on a non-infringing inventive … the rate of innovation, as well as a separate optimal required inventive step that maximizes welfare, with the former …

linked fields. Our analysis uses 1.8 million U.S. patents and their citation properties to map the innovation network and its … strength. Past innovation network structures are calculated using citation patterns across technology classes during 1975 …-1994. The interaction of this pre-existing network structure with patent growth in upstream technology fields has strong …

We study the causal impact of invalidating marginally valid patents during post-grant opposition at the European Patent … participation of a patent’s original examiner in the opposition division as an instrument. We find a disciplinary effect of … invalidation: Affected inventors file 20% fewer patent applications in the decade after the decision. This effect is entirely …

Recent empirical studies suggest a need for a flexible patent regime responding to industry characteristics. In … practice, sector-specific modifications of patent strength already exist but lack theoretical foundation. This paper intends to … make up for this neglect by scrutinizing in what direction industry characteristics influence optimal patent strength. It …

We investigate how international patent activity enables firms from emerging economies to thrive in the global … marketplace. We match Chinese customs data to US patent records, and leverage the quasi-random assignment of USPTO patent … examiners to identify the causal effect of a US patent grant on the subsequent export performance of Chinese firms. Successful …
