Since the first edition of Who Shall Live? (1974) over 100,000 students, teachers, physicians, and general readers from more than a dozen fields have found this book to be a reader-friendly, authoritative introduction to economic concepts applied to health and medical care. Fuchs provides clear explanations and memorable examples of the importance of the non-medical determinants of health, the dominant role of physicians in health care expenditures, the necessity of choices about health at the individual and societal levels, and many other compelling themes.

Now, in a new introduction of some 8,000 words including new tables and figures, Fuchs, often called the "Dean of health economists," concisely summarizes the major changes of the past 37 years in health, medical care, and health policy. He focuses primarily on the United States but includes remarks about health policy in other countries, and addresses the question of whether national health care systems are becoming more alike. In addition to reviewing changes, the introduction explains why health expenditures grow so rapidly, why health spending in the United States is so much greater than in other countries, and what physicians need in order to practice cost-effective medicine.
