I am doing a Master's in Project Management. I am looking for a research topic. I have an interest in Mergers and Acquisitions, anything related to Investment Banking.
My honest suggestion is to assess yourself by listing down your strengths and interest areas. Then carefully select the topic with highest strength and interest. I found this approach very useful in selecting my on areas of research. Simply getting a suggested topic without first weighing strengths and weaknesses can be counterproductive, at times. Best wishes for your research.
Perhaps an interesting topic is: Latin American Mergers and Acquisitions Study.
I suggest this link, which may motivate you in your study: https://www2.deloitte.com/content/dam/Deloitte/br/Documents/mergers-acqisitions/Fusiones-Adquisiciones-America-Latina-Deloitte.pdf
