> Fair enough, looks like lyft only came to NYC around 2014[1]. But does anyone know if the ride share prices in NYC from 2011 [2] to now has significantly changed? You would have to look at how the ride sharing services came about in different cities around the world. The two most popular ways to measure those effects in economics are differences-in-differences (basically a clinical trial -- you need some very similar placebo city to compare it to) or regression discontinuity design (you need a fairly immediate effect, so assuming people learn to use uber this is out of the question).
