...Robert Schoen Abstract Low fertility levels and later childbearing in many developed countries have reinvigorated the debate between period and cohort perspectives on fertility and on the meaningfulness of the period total fertility rate (TFR). Here, fertility-timing effects are defined as level...

... and in a particular case it is conceptually analogous to the total fertility by birth order but free from the influence of the parity distribution. Fertility of American women for the period 1935–1968 was studied by use of such lifetime probabilities. It appears that the trend of fertility of high birth orders has...

..., Åslund and Grönqvist ( 2010 ) in Sweden, and Angrist et al. ( 2010 ) in Israel all found null effects of fertility on schooling. Comparing these results across prior studies is challenging because of variation in methodologies, periods, and country settings. In this article, we apply a common...
