Necessity of HARA for the concavity of consumption functions

less than 1 minute read

Published:

My paper “Necessity of Hyperbolic Absolute Risk Aversion for the Concavity of Consumption Functions” was accepted at Journal of Mathematical Economics. The publication process was quite efficient. I came up with the idea in late September 2020 and wrote a short paper. After getting rejected from a different journal, I sent to JME. I am very happy that it came out in less than three months after I have started the project. Journals in economics tend to be very slow in the review process, perhaps because many papers tend to be long and unfocused. We should all write concise and focused papers.

This paper marks my 30th published paper. I hope to maintain my productivity.

Website updated

After spending several days, I significantly updated my website. Below is a list of main changes.

  • Previously, there was a “Research” page that I created manually. But it was tedious to list all papers in a consistent style (like journal names in bold face, coauthors in italics, etc.) so I automated it.
  • I omitted publication information except the journal name and year, because I don’t think they are very important and one can easily find by clicking the link to the published paper.
  • I searched for all my paper drafts in my computer and added slides whenever I found them.
  • I merged “Conference proceedings” with “Other publications” because I don’t see a reason to keep proceedings as a separate section given that I don’t have many.

Maybe it is not the best use of my time but I created a “Talks” page, which lists past and future talks and presentations. After spending all afternoon tweaking the code, I created something satisfactory. For now I included only talks in 2023 and 2024 but I might add past ones.
