It reminded me of a 2013 paper by Heiko Jacobs and Alexander Hillert on the alphabetic bias of investors. As “The Economist” very well puts it:
“Over the past century, all kinds of unfairness and
discrimination have been denounced or made illegal. But one insidious form continues to
thrive: alphabetism. This […] refers to discrimination against those whose surnames begin
with a letter in the lower half of the alphabet.”
The Economist., 2001, “As easy as ZYX,” Vol. 360, No. 8237, p. 13.
The article is concerned with our humand tendency not to scroll much further than the first few pages in any document. For academia, the bias presents itself in the likelihood of
- being cited: “articles placed first, second, and third in an issue of top finance and economic journals enjoy all else equal about 50%, 26%, and 17% more future citations than articles published near the back of an issue”
- being invited for review: “in the case of a well-established medical imaging journal, reviewers whose last name started with an A received almost twice as many review invitations as their colleagues towards the end of the alphabet”
However, the authors of the article are more concerned with the general unfairness of alphabetic ordering in economics, politics and mainly financial markets. Based on CRSP mutual fund data and fund flows for NYSE/AMEX and NADAQ stocks the authors find “that a higher alphabetic ranking provides stocks with higher share turnover, investors with lower transaction costs, and firms among others with broader ownership”. Furthermore, the effects “are most pronounced for stocks disproportionately traded by individual or otherwise less sophisticated investors”.
Long story short: Instead of changing from names to numbers, shuffling might be a better solution.
We finish this week with a quick reminder by Dan Popescu:
