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...

The paper develops an integrated baseline model to assess the trade-offs between the natural environment and economic growth. Consumption growth is considered under welfare and sustainability aspects. The framework features capital accumulation and the sectoral structure of the economy as key...

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...
