Suggestions for Master thesis topic

Hi everyone! 

I am currently doing my last year for a Master degree in Finance and about to write my MSc thesis (starting next semester). However, I am having a hard time finding interesting topics. I would like it to be within the sphere of Corporate Finance. If anyone working in IB are aware of any interesting issues and topics worth investigation, these would be well appreciated. Preferably as 'quant' as possible. Seemingly unrelated suggestions are also very much welcome. 

My profile: From the Nordics. Have some experience from PE (interned at Growth Equity firm) and about to do a M&A internship at a boutique firm, and after graduation hope to either join the buy side or IB-BB. 

Thanks guys.
