But it is definitely possible that decision makers choose an "optimal" time frame. In our formalism the adaptive time frame will always be preferred to the fixed one (which I think makes sense), but I think it also makes sense that sometimes you just can't choose the time frame

We don't assume anything about that, but postulate an assumption on what's maximized and look for the types of discounting it predicts. Testing the prediction in an experiment, my first guess would be that the time frame only depends on the circumstances and is not subjective.

Basically yes, although the heart of the argument stays the same in any case - that a DM would choose the option that maximizes the growth rate of her wealth, only that different time frames may correspond to different growth rates.

Thanks! Will have a look. We are definitely interested in testing our predictions in experiments.

Also the unique effect of savings inequality on the trend in the US is still somewhat questionable (compare e.g. Saez & Zucman 2016 to Kuhn, Schularick & Steins 2019)

Math/Stat Students: I have a ton of projects on complex data and network analysis up my sleeve. Theory, methods, applications, you name it. If you want to work on these, make sure you apply to Rutgers Stat PhD. Good idea to DM me so I can put a good word in for you!

I can't answer the first question, but he is now developing a concept called normative equilibrium:

Fits well his current stance towards game theory. The main takeaway of a seminar talk he gave a few months ago at LSE was "I'm done with games".

Only skimmed through it, and their claim seems challenging to prove, but super interesting link:

Because: a. the var-of-logs = var(e)/1-beta^2 expression is irrelevant if convergence is not fast, and is a good approximation if it is; b. It's an objective, not relative, non-arbitrary criterion to tell high mobility from low mobility. See more at

Please do! If not in Copenhagen but further north, you can go to my talk on 27 Nov at in Trondheim on the long-run evolution of absolute intergenerational mobility. Both papers are here: 1. Mobility () 2. Discounting ()

מזמן לא הייתי בתל אביב בחול המועד, אבל פריז באוגוסט מזעזעת. הדבר הקרוב ביותר לסבל שלי מהחום באוגוסט 2018 בפריז היה הסבל שלי מהחום באוגוסט 2004 בקציעות.

This tweet has to include an illustration (with a sign saying "we are the 1%" on the top of the heap). I wish I could do it myself, but I think we all remember my last illustration in the jungle room...
