Why paying women to have more babies won’t work

Governments’ concern is understandable. Fertility rates are falling nearly everywhere and the rich world faces a severe shortage of babies. At prevailing birth rates, the average woman in a high-income country today will have just 1.6 children over her lifetime. Every rich country except Israel has a fertility rate beneath the replacement level of 2.1, at which a population is stable without immigration. The decline over the past decade has been faster than demographers expected.
