Many industrialized countries face fertility rates below replacement level, combined with declining mortality especially in older ages. Consequently, the populations of these countries have started to age. One important indicator of age structures is the dependency ratio which is the ratio of the nonworking age population to the working age population. In this work we find the age-specific immi...

Making strict use of Malthus’ (1798) so-called preventive check hypothesis – that fertility rates vary inversely with the price of food – the current study offers a n...

This leads the author to argue that the specific rationale fo...

When German reunification was accompanied by a rapid decline in aggregate fertility rates, researchers particularly assigned high unemployment rates a dominant role for changes in fertility behavior. The aim of this paper is twofold. First, we investigate changes in the timing of first birth in East Germany after reunification. Using data from the GSOEP, we show that even after reunification Ea...
