A fundamental reversal of the traditional fertility-development relationship has occurred in highly developed countries so that further socioeconomic development is no longer associated with decreasing fertility, but with increasing fertility. In this paper, we seek to shed light on the...

Computable OLG growth models and "convergence models" differ in their assessment of the extent to which demography influences economic growth. In this paper, I show that computable OLG growth models produce results similar to those of convergence models when more detailed demographic information...

The longterm historical decline in infant mortality has been accompanied by increasing concentration of infant deaths at the earliest stages of infancy. The influence of prenatal and neonatal conditions has become increasingly dominant relative to postnatal conditions as external causes of death...

We trace the development of numeracy in Poland and Russia from the early 17th century onwards, and numeracy in Belarus, Ukraine, and Lithuania from the 18th century onwards. The fact that western Poland was doing relatively well during the 16th and early 17th centuries, but was not able to...

Adult lifespan variation in most western countries has stagnated since the 1960s, despite continued improvements in longevity. Cross-sectional analyses, however, find that in the 1990s higher socio-economic position was associated with lower lifespan variation. Trends in this association over...

We examine how family, money, and health explain variation in life satisfaction (“happiness”) over the life cycle. Globally, these factors explain a substantial fraction of happiness, increasing from 12 percent in young adulthood to 15 percent in mature adulthood. Health is the most...

Understanding how the process of childbearing influences parental well-being has great potential to explain variation in fertility. However, most research on fertility and happiness uses cross-sectional data, hindering causal conclusions. We study trajectories of parental happiness before and...

This paper investigates the role of states and regions in shaping spatial patterns of non-marital fertility in Europe since 1960 using a dataset of 497 European subnational regions and smaller countries. Almost all regions registered substantial nonmarital fertility increases over the last 50...
