No.
There is no objective correct answer. So while those are great questions for a forum (which we're not), or for our chat room, they're a poor fit for the main economics Q&A site. What on earth would the "accept" checkmark mean? If an answer can't be right or wrong, what does voting mean - in particular, down-voting?
Some sites occasionally use their meta for this sort of question. We could do that. For example, Academia.SE has a single meta question for polls - an idea copied and refined from tex.SE. Answering is done by commenting, and by voting on existing comments. We could do something like that.
