Dear colleagues,
I am planning to apply an interviewing method as a part of a mixed-method approach of mine in my dissertation. Particularly, I am interested in expert interviews. I plan to reach certain experts in the filed (economics) and interview them. I think it will accompany the quantitative methods that I applied. Otherwise, due to the limitations, only quantitative methods fail to encompass the big picture. However, I struggle in finding resources (books) to learn about expert interviewing techniques as a part of the qualitative research method. I would highly appreciate your suggestions. Thank you beforehand.
