INNOVATION – technology 10/2021 Exponential by Azeem Azhar — tech’s dizzying acceleration  2020  How We Will All Solve the Climate Crisis – We only have one Earth. And we have the technology to save it.   by Nicholas Thompson 

We have witnessed significant changes in economic geography over the last years. However, little is known about the spatial concentration of innovation over time. This column uses a novel dataset containing the location of all US patents between 1836 to 2016 to analyse the geography of innovation over time. It finds that while concentration was a high as it is today in the late 1860s, it has seen a substantial decline thereafter, remaining at significantly lower levels for the larger part of the 20th century. It further finds substantial turnover in the identities of top inventing places.
