    Abstract: During the last century, fertility has exhibited, in industrialized economies, two distinct trends: the cohort total fertility rate follows a decreasing pattern, while the cohort average age at motherhood exhibits a U-shaped pattern. This paper proposes a Unified Growth Theory aimed at rationalizing those two demographic stylized facts. We develop a three-period OLG model with two periods of fertility, and show how a traditional economy, where individuals do not invest in education, and where income rises push towards advancing births, can progressively converge towards a modern economy, where individuals invest in education, and where income rises encourage postponing births. Our findings are illustrated numerically by replicating the dynamics of the quantum and the tempo of births for cohorts 1906-1975 of the Human Fertility Database.

    Abstract: This paper explores how two main channels explaining the gender wage gap, namely the heterogeneity of firm pay policies and sex-specific wage consequences of parenthood, interact. We explore the firm heterogeneity channel by applying the model proposed by Card, Cardoso, and Kline 2016. After controlling for individual and firm heterogeneity, we show that the sorting of women into lower-paying firms accounts for 11 % of the average gender wage gap in the French private sector, whereas within-firm gender inequality does not contribute to the gap. Performing these decompositions all along workers’ life cycle, we find evidence that this sorting mechanism activates shortly after birth. These gender-specific and dynamic firm choices generate wage losses all along mothers’ careers, in addition to direct child wage penalties. After birth, mothers tend to favor firms with more flexible work hours and home proximity, which may be detrimental to their labor market opportunities, as, within these contexts, firms may gain relative monopsonic power.

    Abstract: Is the wage penalty due to motherhood larger among highly qualified women? In this paper, we study the effect of parenthood on the careers of high-achieving women relative to high-achieving men in a set of high-earning professions with either nonlinear or linear wage structures. Using Norwegian registry data, we find that the child earnings penalty for mothers in professions with a nonlinear wage structure, MBAs and lawyers, is substantially larger than for mothers in professions with a linear wage structure. The gender earnings gap for MBA and law graduates is around 30%, but substantially less for STEM and medicine graduates, 10 years after childbirth. In addition, we provide some descriptive statistics on the role of fertility timing on the child earnings penalty.

    Abstract: This paper uses an equivalent income approach to quantify the domestic welfare loss due to the Syrian Civil War. Focusing on the (income, life expectancy) space, we show that the equivalent income has fallen by about 60 % in comparison to the pre-conflict level. We also find that the differential between the equivalent income and the standard income for 2016 lies between $75 and $144. Although this low willingness to pay for coming back to pre-conflict survival conditions can be explained by extreme poverty due to the War, the small gap between standard and equivalent incomes tends to question the extra value brought by the latter for the measurement of standards of living in situations of severe poverty. We examine some solutions to that puzzle, including a more general specification of the utility function, the shift from an ex ante approach (valuing changes in life expectancy) to an ex post approach (valuing changes in distributions of realized longevities), as well as considering population ethical aspects. None of those solutions is fully successful in solving the puzzle.

    Abstract: Evaluating policy changes that occur everywhere at the same time is difficult because of the lack of a clear counterfactual. Hoping to address this problem, researchers often proxy for differential exposure using some observed characteristic in the pre-treatment period. As a cautionary tale of how difficult identification is in such settings, we re-examine the results of an influential paper by Melissa Kearney and Phillip Levine, who found that the MTV program 16 and Pregnant had a substantial impact on teen birth rates. In what amounts to a difference-in-differences approach, they use the pre-treatment levels of MTV viewership across media markets as an instrument. We show that controlling for differential time trends in birth rates by a market’s pre-treatment racial/ethnic composition or unemployment rate causes Kearney and Levine’s results to disappear, invalidating the parallel trends assumption necessary for a causal interpretation. Extending the pre-treatment period and estimating placebo tests, we find evidence of an “effect” long before 16 and Pregnant started broadcasting. Our results highlight the difficulty of drawing causal inferences from national point-in-time policy changes. This paper was motivated by an earlier NBER working paper . The authors of that paper have posted a response to this paper . Another NBER working paper addresses issues in both of these papers.
