We don't even have a definition of "productivity" in the realm of programming, so I don't know what anyone would study. I have made a good living on a laptop for years, with no external monitor or any other accessories. I feel productive with this setup, and when I had multiple monitors years ago I didn't feel any boost. I noticed many of the other programmers keeping Facebook or Twitter open on their second monitor at that job, which may have caused a productivity hit, I don't know, because at that job, like every job I've had in my career, we didn't have any way to measure productivity.
