I had/have an academic research agenda on this very question. I’d summarize the evidence as
We expect crowding-out, theoretically and intuitively
The evidence is not solid, and it is very hard to measure
I have a more detailed writeup as part of the ‘synthesis of barriers to effective giving’; chapter ‘Are charities in competition?’
Will try to return to this discussion in more detail if I have a chance. (Also had plans/progress on a synthesis and meta-analysis paper on this, but not sure when if ever I’ll have a chance to return to it.)
