Collaborative knowledge creation: Evidence from Japanese patent data

  title={Collaborative knowledge creation: Evidence from Japanese patent data},
  author={Tomoya Mori and Shosei Sakaguchi},
In this paper, we quantitatively characterize the mechanism of collaborative knowledge creation at the individual researcher level a la Berliant and Fujita(2008) by using Japanese patent data. The key driver for developing new ideas is found to be the exchange of differentiated knowledge among collaborators. To stay creative, inventors seek opportunities to shift their technological expertise to unexplored niches by utilizing the differentiated knowledge of new collaborators in addition to… 


Knowledge-relatedness in firm technological diversification
Patent Value and Citations: Creative Destruction or Strategic Disruption?
Prior work suggests that more valuable patents are cited more and this view has become standard in the empirical innovation literature. Using an NPE-derived dataset with patent-specific revenues we
Growth Through Inter-sectoral Knowledge Linkages ∗
Sectors differ greatly in their degree of knowledge applicability. This paper studies the impact of inter-sectoral knowledge linkages on aggregate innovation and growth. We develop a multisector
Knowledge Creation as a Square Dance on the Hilbert Cube
Surprisingly, in the general case for a large set of initial conditions, the equilibrium process of knowledge creation may converge to the most productive state, where the population splits into smaller groups of optimal size; close interaction takes place within each group only.
Better Workers Move to Better Firms: A Simple Test to Identify Sorting
We propose a simple test that uses information on workers' mobility, wages and firms' profits to identify the sign and strength of assortative matching. The basic intuition underlying our empirical
The Case against Patents
The case against patents can be summarized briefly: there is no empirical evidence that they serve to increase innovation and productivity. There is strong evidence, instead, that patents have many
Growth, innovation, scaling, and the pace of life in cities
Empirical evidence is presented indicating that the processes relating urbanization to economic development and knowledge creation are very general, being shared by all cities belonging to the same urban system and sustained across different nations and times.
IN THIS PAPER we study the large sample properties of a class of generalized method of moments (GMM) estimators which subsumes many standard econometric estimators. To motivate this class, consider
