Good resources for finding relevant researches for SoP?

[aiaiaice]

I'm applying to sociology PhD programs this cycle, but my BA was in econ without any background in sociology so it's a bit hard for me to navigate.

I am currently working on my SoP and a friend who read my statement recommended me to elaborate more on my research interest and show more knowledge of the field. I'd like read about some relevant & well-received researches in my interest area (economic sociology / inequality and stratification / political sociology) to concretize my research topic and become more knowledgeable about what's going on in the field. Hopefully something I can mention in my SoP...

Does anyone have any recommendations for doing this? Any advice would be greatly appreciated.

The first place to look is the latest research done by faculty working in those areas at departments you're interested in. The second place would be going to sociology journals (e.g. American Sociological Review) and searching for keywords of interest, ideally looking at recent issues (say, 2012 onwards). Hopefully those will get you to a point where you can start to understand the body of literature on a particular sociological topic, such as by seeing common citations between different papers, or seeing papers on the topic with a ton of citations.
