The first section is partly finished. We completed and published a paper in the Journal of Economic Literature.
It summarizes ideas on how people deal with limited attention and how how it shapes the whole environment, i.e. markets and policy. The paper has already been widely cited and used as a teaching material at numerous institutions, too.
Another paper was published in Nature and also has already been successful. It focuses on simplified information provision to public during the covid times. It shows that sufficiently transparent information about doctors’ beliefs can help move the public’s beliefs in the direction of those of the physicians.
There are two other paper related to limited information provision, one published in the Journal of Economic Theory.
Moreover, we have been working on development of methods that could describe existing narratives empirically. We developed a large language model (LLM) that summarizes a scraped text and can answer questions such as “Is inflation caused by deficit or by low interest rates?” This is meant to describe beleifs of those writing the text on the internet.

In the second section we are still in the preparation stage. One area where we progressed quite a bit is study of the decentralized market via focusing on a taxi market where customers decide on which taxi to choose among those in the vicinity.
In the third section, we have been collecting data from the system of University of California in San Francisco and running initial analysis. Now we have a database of million of patient visits with detailed features in each visit. In the first stage we are focusing on “fatigue of doctors”, i.e. how their performance and working habits change as a function of already performed work and what type of patients they interacted with recently.
We do already have initial results, which we are starting to present at invited seminars these very days. We have slides, but there is no paper yet. The interaction between physicians’ performance and behavior, and past interactions is very interesting. We see that they make vastly different choices if they interacted with complicated patients in recent past.
