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 …

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 …

own innovation. The analysis predicts that the willingness to enforce IPR is U-shaped in a country GDP: small … enforcement of IPR yields a higher level of innovation and global welfare only if the developing country does not innovate. A …

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 …

To explain this novel result we extend the usual theory of innovation activity by … rigidities with respect to a firm’s individual innovation capacity, which leads to a differentiation between a long run and a …

This paper analyzes the optimal protection strategy for an innovator of a complex innovation who faces the risk of … imitation by a competitor. We suppose that the innovation can be continuously fragmented into sub-innovations. We characterize … the optimal mix of patent and trade secrets when the innovator faces a strict novelty requirement and can only patent a …

patentability standards at PTOs (Patent and Trademark Offices awarding so-called bad patents), not only “false innovators” have the … chance of being granted patents but also, and more interestingly, “true innovators” are forced to patent more intensively … distortions caused by bad patents. Moreover, we show that introducing a two-tiered patent system is unlikely to improve market …

Substantial elements of innovation have been observable during recent years in rig supply, in particular regarding …
