A recent book by Robert J. Gordon titled The Rise and Fall of American Growth shines a light on technological innovation and its past and future impact on growth. The premise of the book is that the innovations of the special century (1870 – 1970) cannot be replicated. As such, the author does not envision a return to growth for America (hence the title). The book is very well written, and I will touch on aspects of it in future posts. For this post, I’d like to gauge the reader’s level of optimism or pessimism.
