Brokers play a critical role in the evolution of innovation systems by accessing and diffusing external knowledge. However, while brokers’ activity allows benefits for the entire system, it entails costs for those who play the broker role. Using patent data to analyse inter-city networks in Latin America, we identify broker cities and estimate the effects of brokerage on patenting outcomes between 2006 and 2017. Our findings reveal that cities holding a central position in the network show higher patenting activity; however, being a broker, particularly connecting Latin American cities with the rest of the world, negatively influences patenting outcomes.

This paper analyzes international collaboration networks associated with invention and patenting in Latin America between 1970 and 2017. We use data from US patent records retrieved from the Patents View platform. We select patents with actors located in Latin American countries and create networks where nodes are countries and links represent collaboration among inventors and among patent owners located in different countries. We apply various social network analysis methods...

Abstract: This study develops an agent-based model which seeks to analyse the innovation network of an economic sector that is intensive in highly trained human resources. This sector is composed by agents that face a restriction to the incorporation of new capital, and have the possibility to choose the proportion of its available capital devoted to each of the two available goods. These agents have a menu of three strategies to seek to innovate, and thus increase their productivity. The adjustment of these strategies is done endogenously and results in a process that determines the structure of the innovation network. The consideration of public policies in the system leads to the conclusion that the effect of policies depends heavily on the specific population to which they are directed. These results are manifested both in the performance of the system and in the network structure that emerges from the evolution of the model.
