The economics—and ethics—of surge pricing continue to be in the news, thanks to Uday Kotak’s attack on policies that act against free markets. In this context, a recent interview with Uber’s head of economic research shows how efficiently the taxi service works the system.

It has also discovered that an arbitrary number with a decimal point works much better in convincing users to accept surge as compared to a round figure. Scientific stuff, eh?
