Growth in life expectancy during the last two centuries has been attributed to environmental change, productivity growth, improved nutrition, and better hygiene, rather than to advances in medical care. This column traces the development of medical care and the extension of longevity in the US from 1800 forward to provide a long-term look at health and health care in the US. It demonstrates that the contribution of medical care to life-expectancy gains changed over time.

Foreign goods and workers are regularly blamed when the national economy is performing poorly. Economic theory suggests that trade and migration are substitutes – one can import cheaper products from a trade partner, or one can import the foreign workers themselves to narrow the difference in international factor prices. Yet, empirically this is not obvious. Based on available long-run data for international trade and migration since the late 19th century for the US and Canada, this column finds that during the interwar period, trade and immigration did in fact appear to be substitutes.
