You can find a bunch of articles by googling "never accept counter-offer" but they don't provide much in the way of hard data, it's mostly anecdotes.
Some articles say your relationship with your employer is like your relationship with your partner - any indication of looking elsewhere is disloyalty, and will inevitably lead to a break-up down the line if not now. Or it'll put you first in line for lay-offs. Other articles say your employer has a moral duty to pay a 'fair' amount, and if you can get 20% more elsewhere, that shows you should resent your current employer, and leave on principle. Or that threatening to quit and not following through makes you "the boy who cried wolf" and shows a lack of integrity. Or that the fact you were interviewing in the first place shows you weren't satisfied and fulfilled at your current job.
A lot of the articles are written by recruiters. They don't want people to take the counter-offer because it means they miss out on their 20% commission.
Personally I once accepted a counter-offer and it went just fine - in fact, the job offer would have needed an hour-long commute, whereas my job at the time had a 20 minute commute, so I got the extra money without the extra commute. It didn't limit my career or get me laid off or anything.
