Revealing the intricate effect of collaboration on innovation

Por • 15 sep, 2013 • Category: Educacion

We study the Japan and U.S. patent records of several decades to demonstrate the effect of collaboration on innovation. We find that statistically inventor teams slightly outperform solo inventors while company teams perform equally well as solo companies. By tracking the performance record of individual teams we find that inventor teams’ performance generally degrades with more repeat collaborations. Though company teams’ performance displays strongly bursty behavior, long-term collaboration does not significantly help innovation at all. To systematically study the effect of repeat collaboration, we define the repeat collaboration number of a team as the average number of collaborations over all the teammate pairs. We find that mild repeat collaboration improves the performance of Japanese inventor teams and U.S. company teams.



La innovación tecnológica como arista de la transformación social

el Presidente Chávez señaló la necesidad de darle contenido al Proyecto Nacional venezolano en el área de ciencia y tecnología. En ese momento expresó: nuestra sociedad socialista, una sociedad de conocimiento, más que de conocimiento, más allá, una sociedad con conocimiento, con sabiduría, la sociedad del talento, la sociedad creadora, creativa, ese es el rumbo que nosotros le hemos dado a nuestro Proyecto Simón Bolívar, pasar por la Sociedad de la Información, la Sociedad del Conocimiento, rumbo a la Sociedad del Talento … (CENDITEL, 2010 )



India fails test of ‘knowledge economy’

Por • 1 dic, 2012 • Category: Internacionales

There are few signs that US dominance in the knowledge economy will wane, thanks in no small part to its open-door policy for Chinese and Indian researchers and innovators. According to a recent study in Nature magazine, 17% of the scientists in the US are Chinese and another 12% are Indians. It is quite probable that these Indians have a higher research output than India-based scientists. The skills crisis among India’s young population is in large part due to pervasive shortages of qualified faculty. In a recent interview, Shyam Sunder (Yale School of Management) observed that: «Our best brains are selling soaps and getting into civil service» but «we are not able to attract them to a sector that is most important to us – education – particularly higher education.» As a result, even prestigious institutions – like the Indian Institutes of Technology and the Indian Institutes of Management – are facing a shortage of qualified faculty. As higher education undergoes further expansion, these shortages can only mount.



Empirical confirmation of creative destruction from world trade data

Por • 14 dic, 2011 • Category: sociologia

We show that world trade network datasets contain empirical evidence that the dynamics of innovation in the world economy follows indeed the concept of creative destruction, as proposed by J.A. Schumpeter more than half a century ago. National economies can be viewed as complex, evolving systems, driven by a stream of appearance and disappearance of goods and services. Products appear in bursts of creative cascades. We find that products systematically tend to co-appear, and that product appearances lead to massive disappearance events of existing products in the following years. The opposite – disappearances followed by periods of appearances – is not observed. This is an empirical validation of the dominance of cascading competitive replacement events on the scale of national economies, i.e. creative destruction. We find a tendency that more complex products drive out less complex ones, i.e. progress has a direction. Finally we show that the growth trajectory of a country’s product output diversity can be understood by a recently proposed evolutionary model of Schumpeterian economic dynamics.
