Waiting for one more reviewer due to being unresponsive - what to expect? I have submitted a paper to an Economics journal in September 2019. It was assigned to reviewers in October of the same year. When being assigned, I was told by the journal office, that the review process might take between three to four months. I have sent an email to the journal office to which they have replied to me today saying that, one of the reviewers has already given his/her reviews, but the journal is still waiting for the second reviewer to submit his/her reviews? They told me that the concerned reviewer has become unresponsice
and they will help to expediate the process.
Furthermore, journal office mentioned that they will keep monitoring the situation nd the editor will proceed to a decision as quickly as possible once sufficient reviews have been received.
Does the fact that one of the reviewers who has already provided his/her reviews bears any significance in terms of revision, acceptance or rejection?
And what is the significance that one of the reviewers have been unresponsive?
Thanks.

If the reviewer is unresponsive, they effectively withdraw. Again the same basic options are available to the editor: they can find another reviewer, or they can make a decision based on the single review they've received. When you get the decision you'll be able to tell which option they took.

I suppose the fact the reviewer went unresponsive indicates that your manuscript is not so groundbreaking that people are actively excited to review your manuscript. But even drawing this conclusion is dangerous - the reviewer could simply have fallen ill, for example - so the brief answer is &quot;no&quot;. It's simply something too circumstantial to draw conclusions about.
On the bright side, having one review completed is progress, so you should expect to receive a decision in a shorter time than if you withdraw and submit the manuscript at another journal.
