Regarding the impossibility of resolving questions about causal effects: Take the example I gave in the screenshot. I would think that there are plausible observations in the coming years that make the causal claim “monopolists using their market power → inflation” very unlikely, right? E.g. if the inflation decreases without observing changes in competitiveness or something like this. And yes, a retrospective survey might be the gold standard, though I suppose I’d feel somewhat comfortable trusting a careful economist to make a bunch of judgements by herself.
And regarding buy-in, do you have an idea how the members themselves initially got interested in participating? I guess if you want to replicate the IGM panel, you’d need to have some well connected people on board fairly early. Maybe due to econs proximity to politics it’s also very natural for them to want to speak out about policy issues.
I’m skeptical that there’ll be a consensus 5 or 10 years from now on whether market power was a key contributor to 2021 inflation; there are just too many confounding factors blocking an inference like “inflation decreased without changes in competitiveness, so market power must not have been causing inflation.” It’s true that retrospective consensus sometimes emerges (for example, that financial deregulation was at least partly responsible for the Global Financial Crisis), but this is pretty rare.
I’m not sure how the forum started. I assume a key factor in making the participants interested was that the panel was started by a reputable institution (Chicago Booth) that could guarantee a wide audience. I wouldn’t guess that economists are more willing than academics from other fields to express views on policy-relevant issues; I suspect political scientists, sociologists, etc. would be similarly willing.
Thanks, that all is useful feedback.

Thanks, that makes sense!
