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 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...

We assess the long-run growth effects of rising longevity and increasing the retirement age when growth is driven by purposeful research and development. In contrast to economies in which growth depends on learning-by-doing spillovers, raising the retirement age fosters economic growth. How...

Does the distribution of income within a country become more equal as it grows richer? This paper uses plausibly exogenous variations in trade-weighted world income and international oil price shocks as instruments for within-country variations in countries' real GDP per capita to examine this...

Over the past decade, China’s growth model has become more reliant on investment and its footprint in global imports has widened substantially. Several economies within China’s supply chain are increasingly exposed to its investment-led growth and face growing risks from a deceleration in...

During the past decade, the average Chinese earns roughly 9 times less and is 10 times less productive than the average American at purchasing power parity. Current consensus attributes large differences in output per worker to differences in total factor productivity (TFP). Evidence suggests...
