Jonathan Skinner of Dartmouth University reviews “Why Not Better and Cheaper? Healthcare and Innovation” by James B. Rebitzer and Robert S. Rebitzer. The Econlit abstract of this book begins: “Considers why the US health-care system is becoming neither better nor more affordable over time, contending that the health sector generates the wrong kinds of innovation by making it easy to profit from low-value innovations and difficult to do the same from innovations that reduce care costs.”
