I don't understand the downvotes here. Results are results. I can understand paying a person more if you are worried about providing a living wage, but really you are paying them to do a service for the company.

If you are looking at two remote candidates offering to do the same work, the fact that one lives in India and the other in Paris should not make a difference in what you pay them (well, timezone difficulties aside). You should pay well for good work, and if it's not going to be good work you shouldn't pay at all. 'Pay well' is not relative to where a person lives, it's relative to the market value of that work.
