摘要

TO PARAPHRASE the economist John Maynard Keynes, society is controlled by defunct thinking. Once upon a time, economists assumed that humans were perfectly rational and had access to all the information they needed. This statement is so plainly untrue that some may be surprised that it ever took hold. Nevertheless it made for simple theories that were easy to work with and that's why, over the decades, economic thinking was influenced by a "dark love of inappropriate scientific elegance", as Emanuel Derman, a financial engineer, put it (see page 32). Fortunately, there's been much progress in connecting economics with the real world. On page 8 we report the extent to which a few companies control the global economy, and the perils of them being too tightly interconnected, before examining the benefits of placing a realistic value on humanity's long-term future.
