Add `hhi` package to the Econometrics TV?

[pdwaggoner]

Hi - I am not sure if this package is appropriate for this TV, but given that the HHI measure was originally derived for explaining market competition, it seemed like there could be a fit. Its been downloaded over 23k times, and has been stably released since 2018. Feel free to check it out here: https://github.com/pdwaggoner/hhi

Let me know if this makes sense or not. Thanks for considering!

Thanks for the suggestion. The topic is relevant to the Econometrics task view but I feel that the functionality is extremely limited. The Herfindahl index (or Herfindahl-Hirschman Index) is one of a bunch of inequality, concentration, and poverty measures in the ineq package which also support Herfindahl indexes with a parameter differing from 1.

There are many cases where we list alternative implementations next to each other but the hhi() function has less than 20 lines so I'm not sure how useful the addition is in this case.

I'm biased, though, because ineq is my package (my very first actually). So I leave the final decision to my co-maintainers.

Thanks nevertheless & best wishes!

Thanks for the reply. Certainly agreed on the limited functionality. This was also my first, originally developed to support my dissertation. Again, no worries if there isn't a fit. Thanks for considering

I was about so write something similar, so I second Achim's assessment.

Maybe we add Herfindahl-Hirschman Index to the description of ineq in the Task View? -> "some basic tools such as Lorenz curves, Pen's parade, the Gini coefficient, Herfindahl-Hirschman index and many more." So to make it more obvious ineq includes it.

Good idea!

Sounds good. Thanks and good luck!
