I have to write my bachelor thesis in the coming months and I was planning on replicating one of the leading papers of the last years in the field of macro economics. Problem is that I am insufficiently acquainted with the literature and my supervisor does not want to help me in any way with regards to the topic/research question. My hope is that the community could advise me on what the most important/influential papers have been the last 5 or so years in the field. Any help is appreciated.
Your supervisor might want for you to come up with a research question yourself, maybe because that's part of the assignment. At the thesis, you should be able to demonstrate independent thinking rather than being told what to do for an assignment, and your supervisor might want you to do some more research on your own. However, it is also part of his/her job to give you guidance on the relevant fields where s/he considers your skills fit best.
Since you want to research on macro, check which papers were part of the recommended readings for that subject and ask your supervisor if s/he would recommend you to start there.
Another way to get ideas is to scout the papers in economics search engines. The IDEAS/RePEc can be a good starting point. You can look for topics and sort by citations. Elsevier also has a list of most cited work in economics since 2013. Keep in mind that importance in academic terms is usually often measured by number of citations.
If you want a more mainstream reading, I'm sure a google search will also help you find articles like this list of 2017's most important researches.
