The "code economy" refers to the evolving technologically-driven environment we live in. In services or manufacturing, outputs emerge more and more from coded computerized systems and less as assembled mechanical devices and procedures. Industries seek algorithms to make software not only morepliable for firms' development of products and services, but also to market them and ease their purchase and use by consumers. This process automates jobs. It gives increasing economic advantage to entrepreneurs who can harness "code" to serve on the large scale the growing niches into whichconsumers are organized. Yet, mastering the "code" also gives individuals and informal social networks the resources to bundle products and services and put them up for sale and convenient use at more local levels. The economics of the rest of the 21st century will see the movement away fromtraditional firms and more toward people's relying on themselves as the sources of their livelihoods.The code economy has clearly not developed in a vacuum. Invention, innovation, and the pursuit of happiness have characterized human activities for centuries. What is changing is how societies and individuals radically value endeavors in life differently from even a decade ago, most notably awayfrom industries organized as "command and control" systems. In The Code Economy, Philip Auerswald investigates how economists themselves have been hard pressed to gauge new economic indices of satisfaction that go beyond traditional measures. He explores how the code or "shared" economy reaches intodomains such as health, where greater longevity, the popularization of medical knowledge, and the emphases on preventive care and wellness will complement the delivery of medical services. Further, living in the code economy will prompt people to orient their children's futures to more self-reliantpursuits and seek investments that truly serve them and not the institutions that have traditionally dominated the financial and economic worlds.
