The euro has become a means by which superior German productivity is able to gain an absolutely unbeatable advantage over the whole eurozone territory.
If women's choices - such as taking time off to rear children - make them less productive in the economy, does adolescent boys' behavior in school make them even less so, because they are missing the educational potential of their formative years?
The biggest drag on global growth in the coming decade will be demographics in the developed world.
The demographics to which he referred was the low fertility rate and the large proportion of elderly.
The striking thing about America is - it's historically, extraordinary unusual, I don't of any other instance - is that productivity of workers and wages have not moved in tandem.
Growth in productivity has diverged from growth in the share that working people can expect right across advanced economies, but this trend started earlier and has been more pronounced in the U.S.
Greenspan's eventual explanation for the growing gap between stock prices and actual productivity was that, fortuitously, the laws of nature had changed -- humanity had reached a happy stage of history where bullshit could be used as rocket fuel.
High-skilled workers increasingly choose lucrative jobs that don't serve or supervise low-skilled workers. Low-skilled productivity and wage growth has lagged as a result.
We will only keep people from fleeing the countryside into urban favelas, villas miseries, shantytowns and squatter villages when the productivity gap is closed between what brute labor on the soil can accomplish and what advanced technology makes possible today - and will make possible tomorrow.
Europe's demography is developing towards a smaller working population in an ageing society.
The difference between the best worker on computer hardware and the average may be 2 to 1, if you're lucky. With automobiles, maybe 2 to 1. But in software, it's at least 25 to 1. The difference between the average programmer and a great one is at least that. The secret of my success is that we have gone to exceptional lengths to hire the best people in the world.

Large companies everywhere tend to be more productive than small ones. But the gap in productivity is far wider in developing countries.
Taken as a whole, Europe's share of world output is projected to fall by almost a third in the next two decades. This is the competitiveness challenge - and much of our weakness in meeting it is self-inflicted. Complex rules restricting our labour markets are not some naturally occurring phenomenon.
A great coder can easily be 50 times more productive than a mediocre one, while bad ones ultimately have negative productivity.
