This article investigates the consequences of population ageing for long-run economic growth perspectives. We introduce population ageing into a generalized model of endogenous technological change incorporating the model of Romer (1990) and Jones (1995) as special cases. We find that increases...

Conventional R&D-based growth theory argues that productivity growth is driven by population growth but the data suggest that the erstwhile positive correlation between population and productivity turned negative during the 20th century. In order to resolve this problem we integrate R&D-based...

In the second half of the 20th century, most industrialized countries experienced declining fertility, rising life expectancy and a slowdown of population growth. Standard models of R&D‐based growth predict that a decline in population growth reduces economic growth. We argue that this...

In recent decades, most industrialized countries experienced declining population growth rates caused by declining fertility and associated with rising life expectancy. We analyze the effect of continuing demographic change on medium- and long-run economic growth by setting forth an R&D-based...
