What would happen if Donald Trump doesn't concede on election day if he loses the election in 2016?
Have there been other instances of presidential candidates refusing to concede?
Yes, there have been instances in the past where presidential candidates have refused to concede, but they have usually done so after legal challenges to the election results. It is rare for a candidate to refuse to concede outright without any evidence of fraud or other irregularities.
