Duh, the answer is no. But Alex Tabarrok at marginal revolution, http://www.marginalrevolution.com/marginalrevolution/2009/08/inefficient-journal-submission-policies.html#comments, told his microbiologist wife that if she submitted a paper with correct Reference formats she would be signaling that she is a "newbie," with nobody who knows anything doing that in economics. She followed his advice only to have her paper rejected upfront. He complained about an "inefficient equilibrium" of journal policies in the hard sciences, only to have lots of hard scientists point out that it is two lines of LaTEX to change formats. Of course, few economics journals require LaTEX, and few economists use it Now it is true that econ journal editors generally tolerate submissions not in correct formats, which get "fixed" later if accepted, and a majority of submissions do come in that way. But it is no signal of intelligence, experience, or anything else impressive for several reasons.
1) It is a pain in the ass for editors to ask accepted authors to fix this later, and is costly in time if the journal staff has to do the fixing themselves.
2) If anything, journal editors are somewhat sympathetic to "newbies" trying to get tenure and publish out of their dissertations.
3) Trying to signal that one is "experienced" by any means is a lost cause unless the editor has heard of the submitter. If the editor has not heard of the submitter and realizes the person is experienced, this simply counts against them, a loser who has been around but so pathetic or unproductive or worthless that that they are unheard of by the editor. If the editor has not heard of someone, better almost to be a "newbie." (Although, of course, showing multiple citations to one's own work in respectable journals in the paper can offset such an impression.)
3) Having correct Reference formats may signal that the paper has been submitted first to the journal, which sometimes strokes the egos of editors.
4) Of course, worse than simply having incorrect formats (which is tolerated in econ) is having sloppily incomplete or incorrect references, with papers cited in the paper not there or papers in the references not cited, or misspelled names or incorrect years or paper titles, etc. This is just incompetence and signals such pretty clearly. Bottom line is that References that are complete and accurate and in proper format signal professionalism, not some damning lack of experience.
