Uber's losses extent beyond $1 billion - is there a path to profit?

A little of bit of an Economics/Business mash-up. Uber has made a loss of $1.1bn - yes, that's right - a loss. So how can the company stay in business?

In the first place, economists might wonder about this - what's the short-run shut down point for a business?

Business management students might start thinking about Uber's balance sheet - what does it look like, and again, what are the practicalities of staying in business whilst making such a loss? the other thing to note is that revenues have increased, as have the number of journeys.
