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...

We analyze the impact of increasing longevity on technological progress within an R&D-based endogenous growth framework and test the modelś implications on OECD data from 1960 to 2011. The central hypothesis derived in the theoretical part is that - by raising the incentives of households to...

Economists use micro-based and macro-based approaches to assess the macroeconomic return to population health. The macro-based approach tends to yield estimates that are either negative and close to zero or positive and an order of magnitude larger than the range of estimates derived from the...

In the aftermath of World War II, the world's economies exhibited very different rates of economic recovery. We provide evidence that those countries that caught up the most with the U.S. in the postwar period are those that also saw an acceleration in the speed of adoption of new technologies....

We present evidence on the differences in the intensity with which ten major technologies are used in 185 countries across the world. We do so by calculating how many years ago these technologies were used in the U.S. at the same intensity as they are used in the countries in our sample. We...

We analyze the effects of declining population growth on automation. A simple theoretical model of capital accumulation predicts that countries with lower population growth introduce automation technologies earlier. We test the theoretical prediction on panel data for 60 countries over the time...

Over the past 15 years, labor-quality growth has been very strong--defying nearly all earlier projections--and has added around 0.5 percentage points to an otherwise modest U.S. productivity picture. Going forward, labor quality is likely to add considerably less and may even be a drag on...
