We propose a new method to characterize firms' inventive activities via topological data analysis (TDA) that represents high-dimensional data in a shape graph. Applying this method to 333 major firms' patents in 1976—2005 reveals substantial heterogeneity: some firms remain undifferentiated;...

Where do firms innovate? Mapping their locations and directions in technological space is challenging due to its high dimensionality. We propose a new method to characterize firms’ inventive activities via topological data analysis (TDA) that represents high-dimensional data in a shape graph....

The usual models of endogenous growth treat knowledge codification as a byproduct of R&D and as costless. In contrast … to this, one can observe great efforts of private firms for the purposeful codification of knowledge. We incorporate … costly knowledge codification in an overlapping generations framework of endogenous growth and show that the steady …
