How should you refer to yourself in a paper?
This usually depends on whether or not you paper will be reviewed double-blind or not. If it's going to be double-blind, then you need to refer to yourself in the third person (i.e. by name, "Fred, et al.") rather than using a pronoun. If it's only going to be single-blind review, then I think it's a matter of style whether you use a pronoun or refer to yourself by name, though the venue you are submitting to, or your field, may have preferences. In which case, you should ask around.
