Paul Krugman:

I’ve been following some of the discussion about Uber, Lyft, and all that, and I have a few unoriginal thoughts. Well, strictly speaking they are original, in the sense that I haven’t read them anywhere else — but surely they’re out there. So this post is partly a bleg for references.
 
 Anyway: the big benefit from new IT-mediated car services will come if they make it possible for lots of people — and not just people in Manhattan — to live without owning their own cars. And if you think about it, you can see how that might work.
 
 Right now, if you live in places without exceptionally good public transportation, it’s very difficult to manage without a car. Yet when you think about it, for most people owning a car is quite wasteful. It’s an expensive item of equipment that sits idle most of the time; it requires parking (and often a parking structure) both at origin and at destination; it requires maintenance and is a big hassle all around.
 
 So reliable, quick-response chauffeur services could free many people from the need to tie up all those resources in a consumer durable that they only use now and then. And from a social point of view it would avoid the need to tie up so much capital that sits unused most of the time.
