This chapter documents instances from past centuries where inventors freely shared knowledge of their innovations with other inventors. It is widely believed that such knowledge sharing is a recent development, as in Open Source Software. Our survey shows, instead, that innovators have long...

This paper examines the relationship between patents, appropriability strategies and market for technologies in the English brewing industry before 1850. Previous research has pointed to the apparent oddity that large-scale brewing in this period was characterized both by a self-aware culture of...

In this paper, we construct a new index that measures the strength of intellectual property (IP) protection for plant varieties for 69 countries over the period 1961-2011. We examine the statistical properties of the index and we compare it with other measures of IP protection. We conclude that...

The diffusion of innovations is supposed to dissipate inventors' rents. Yet in many documented cases, inventors freely shared knowledge with their competitors. Using a model and case studies, this paper explores why sharing did not eliminate inventors' incentives. Each new technology coexisted...

This paper revises and updates the Campi-Nuvolari index of intellectual property protection for plant varieties (Campi and Nuvolari, 2015). The new index has been updated and provides yearly scores for the period 1961-2018 for a total number of 104 countries, which have legislation on plant...

The ambiguity of the empirical results on the relationship between copyright and creativity calls for a better theoretical understanding of the issue, possibly enlarging the analysis to other factors such as technology and copyright enforcement. This paper addresses these complex policy issues...

We examine the potentialities of a new indicator for measuring the value of English patents in the period 1617-1841. The indicator is based on the relative visibility of each individual patent in the contemporary technical and legal literature as summarized in Bennet Woodcroft's Reference Index...

In this paper, we construct a new index measuring the strength of intellectual property (IP) protection for plant varieties in 69 countries over the period 1961–2011. We examine the statistical properties of the index and compare it with other indicators of IP protection. We conclude that the...

This paper presents an exploratory study on the characteristics of inventive activities as captured on the basis of the analysis of a data-set of R&D awards. Our data source is the "R&D 100 Awards" competition organized by the journal Research and Development. Since 1963, the magazine (which at...
