Im vorliegenden Beitrag werden die wechselseitigen Beziehungen von demographischen Veränderungen und Arbeitsmarktentwicklungen anhand eines Literaturüberblicks diskutiert. Insbesondere werden die Effekte von demographischen Strukturen und Prozessen auf die Lohnstruktur und auf die...

Long-term consequences of childbearing postponement for the population size are considered. General relations are obtained, which imply that the cohort NRR, the final generation length, and dynamics of the number of genealogical lines determine the final population trend. The period fertility...

The classical result by R.A. Fisher concerning reproductive value dynamics is expanded to the case of varying vital rates with a constant cohort Lotka's r. Based on the demographic potential approach, generalization of the concept of reproductive value is introduced, which exhibits exponential...

Conventional R&D-based growth theory suggests that productivity growth is positively correlated with population size or population growth, an implication which is hard to see in the data. Here we integrate micro-founded fertility and schooling into an otherwise standard R&D-based growth model....

Empirical studies indicate that the transition to parenthood is influenced by an individual's peer group. To study the mechanisms that create interdependencies across individuals' transition to parenthood and its timing we apply an agent–based simulation model. We build a one-sex model and...

How persistent and universal has the two child family ideal been in Europe during the last three decades? We analyse responses of women of reproductive age from 168 surveys conducted in 37 countries in 1979-2012. A two-child ideal has become nearly universal among women in all parts of Europe....

This paper discusses results of the global survey of experts on the future of low fertility in low-fertility countries. The survey was coordinated by the Wittgenstein Centre for Demography and Global Human Capital as a part of an effort to produce global argumentbased population projections by...

We assess Africa's prospects for enjoying a demographic dividend. While fertility rates and dependency ratios in Africa remain high, they have started to decline. According to United Nations projections, they will fall further in the coming decades such that by the mid-21st century the ratio of...
