This study investigates the general equilibrium effects of a fertility shock under different intergenerational transfer schemes. The effects on lifetime income and utility for different generations, as well as the effects on factor prices, are analyzed in a three-period overlapping generations...

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...

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....

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...

In this paper, the relation between income inequality and population growth is analized from a Darwinian perspective. A Markov chain population growth model is presented and estimated using data from the German Socio-Economic Panel (SOEP). We estimate both population growth rates and...

Seit der letzten Bevölkerungsvorausschätzung des DIW Berlin im Jahr 2004 haben sich zwei Parameter entscheidend verändert: Die gesetzliche Neuregelung der Zuwanderung hat seit 2005 zu einem starken Rückgang der Zuzüge geführt, vor allem bei Spätaussiedlern und Asylbewerbern, und eine...

Die Bevölkerung in Deutschland wird in den nächsten Dekaden schrumpfen und altern. Die mittleren Varianten verschiedener Bevölkerungsprojektionen gehen von einem Rückgang um über 12 Millionen auf rund 70 Millionen Einwohner im Jahr 2050 aus. Das Medianalter in der Bevölkerung wird...
