Went to Area 51 and saw that the only thing that "Needs Work" on Economics StackExchange is the portion of questions answered.
As of now, there are 2,136 questions that are "unanswered." Of these, 359 questions are actually answered, but the question asker didn't accept any answer. Using the current one, we'd have around 76% of questions answered. But if we count the questions that are answered but none are accepted, we'd have 80% of questions answered.
Indeed, the quality of the answer might not be up to the asker's expectation. But I'm quite sure there are instances where the asker gets the helpful response, but is new to StackExchange and so didn't realize the importance of accepting an answer.
Is there a way to encourage/remind new users to accept an answer, if there's one?
