Will the world really be 50 million workers short by 2030?

Nvidia CEO Jensen Huang says the world faces a severe labour shortage – 50 million workers by the end of the decade. The boss of the world’s most valuable company thinks humanoid robots will be needed to fill the gap.

But is this prediction based on solid evidence?

Tim Harford looks at the calculations behind the claim with Rajiv Gupta, a technology expert at Boston Consulting Group, who is the likely source of the 50 million figure.

Gun laws and gold medals (WS)

Gun laws and gold medals (WS)

Last week's mass-shooting at a cinema in Colorado has - not surprisingly - intensified America's bitter and long-running argument with itself about gun control. The argument is political and highly partisan. But it is also practical: would tighter gun laws actually lead to fewer gun deaths? You might think it's obvious that they would. But it seems the evidence isn't quite that clear. Also: how have Olympians changed in the last century?

Has clamping down on drugs made the Tour de France slower? (WS)

Has clamping down on drugs made the Tour de France slower? (WS)

The Tour de France, we are told, has finally cleaned up its act and clamped down on the use of performance-enhancing drugs. But if it has, should we expect today’s drug-free riders to be slower than their drug-fuelled forebears? Can statistics tell us whether the Tour de France really is cleaner than it was? Also in the programme: does when you retire influence when you die?
