Back in the 1700s, the British government paid sea captains to take felons to Australia. About a third of the males on one particularly horrific voyage died. The rest arrived beaten, starved, and sick. I mean, they were hobbling off, those who were lucky enough to survive.




This was a scandal back in England, so the government tried to fix it with all different kinds of rules. Force the captains to bring a doctor along. Require them to bring lemons to prevent scurvy. Have inspections.
Raise captains’ salaries.
The clergy begged the captains, for humanity’s sake, to take better care of the prisoners.
None of it worked.


Instead of paying for each prisoner that walked on the ship in Great Britain, the government should only pay for each prisoner that walked off the ship in Australia.
And in fact, this was the suggestion which in
1793 was adopted and implemented. And immediately, the survival rate shot up to 99%.



Before the captains were paid to keep the convicts alive, they had different incentives —
"like keep food from the prisoners, and then sell the food in Australia,“ they were already paid for the prisoners.
The answer is to reward the captains for keeping the passengers alive, and — voila! — they arrive alive.

If you have economic growth you can push the
