I was not able to find a 'microstructure' tag that I believe could be used on my post.
Can this be created? Or give reasons why its a bad idea.
(I do not have the rep to create it, otherwise I would have)
A tag becomes useful when there are at least several questions that could use that tag. Therefore related questions for that topic can be easily found. Currently a search of this SE site only show one answer where the word is used.
Ask the question and if it is a good question and on topic, and it results in several more questions then there will be a need for a tag.
Please correct me if I'm wrong, but I don't see how that tag really would relate to personal finance. Seems more like an economics term, which is off topic on the site.
