There is one unique age separating early deaths from late deaths such that averting an early death decreases life disparity, but averting a late death increases inequality in lifespans.

This paper aims at contributing to a proposal for the concept and content of the Contextual Database of the Generations and Gender Program. We develop guidelines for data collection by identifying the main focus, the key dimensions as well as the main data types of the GGP Contextual Database....

The increasing recognition that the study of human behaviors has to take into account the multiple contexts in which they occur has opened a promising research avenue in social sciences. It also presents new challenges, e.g., to complement micro-level surveys with the collection of meaningful...

The old age population in developed countries has been increasing remarkably, yet internationally comparable high quality data on oldest-old mortality remain relatively scarce. The Kannisto-Thatcher Old Age Mortality Database (KTD) is a unique source providing uniformly recalculated old-age...

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...

The 1970s worries of the "population bomb" were replaced in the 1990s with concerns of population aging driven by falling birth rates. Across the developed world, the nearly universally-used fertility indicator, the period total fertility rate, fell well below two children per woman. However,...

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...

We study the relationship between leisure and happiness, controlling both for individual and national variables. Using international survey data from 33 countries in 2007, our results show that certain leisure activities, satisfaction from leisure, and meaning of leisure to individuals all...

The "Easterlin paradox" suggests that there is no link between a society's economic development and its average level of happiness. We re-assess this paradox analyzing multiple rich datasets spanning many decades. Using recent data on a broader array of countries, we establish a clear positive...

The worldwide problem with pay-as-you-go, defined-benefits social security systems is not just financial. Through a dynamic, overlapping-generations model where forming a family and bearing and educating children are choice variables, we show that social security taxes and benefits generate...
