I admit that I’m an optimistic person. Â I liked this NY Times article about reduced fatalities per mile flown.Â A few years, Dora Costa and I published a paper that our demand for safety rises faster than the growth in per-capita income. Â This demand should spur both safety efforts by private firms who supply planes and cars and by regulators seeking to improve our standard of living. Â Â I’m now writing a book (with Siqi Zheng of Tsinghua) Â about risk reduction in China caused by the growth of their urban middle class. Â Economic development has its benefits.
