Claims my Russian wife laughs at
You should be glad I think your hair is too short. Given that hair grows, if it were not now too short, it would too soon be too long. Think of it in terms of an S-S model. About half of the time your hair should be too short.
Five points extra credit if you realize that same reasoning means wage and price stickiness may not be as big as problem as we used to think.

I'm not sure "Claims my Russian Wife Laughs At" is the right title. Maybe, "Things I say to lose points with my Russian wife"? Or, "Academic Honesty Trumps Marriage Again"?

I'd appreciate it if someone could mention the title of the work linked to by Tyler. I have access to JSTOR, but through my university library search, but right now I don't even know what to search for. Thanks.

I’d laugh, too, if I were her. Because you noticed it was too short, it must need to grow a lot to be at a length you’d like, and hair grows slowly. In addition, many people like their hair length within a range, and always keep their hair inside that range – never too short and never too long.

Ah, for once I beat MR to something. I posted on the economics of hair length a couple of years ago:

"About half the time" is probably close to correct in general, but the marginal impact of an inch of hair is not the same on the over-optimum side as it is on the under-optimum side, and the amount that it can vary from the optimum is much greater on the over side than it is on the under side.
This varies from person-to-person, but for me it would probably be the case that my hair should be shorter than optimum only 30% of the time. (Long hair can be smushed down to some extent and extremely short hair looks disproportionate to a big head.)

Hair length can have mulitple peaks. Especially true for men.

Does she comment on the optimal length of your hair?

'...many people like their hair length within a range, and always keep their hair inside that range – never too short and never too long.'
Right. Politicians and TV personalities who need to maintain the same look all the time, for instance. Ronald Reagan got his hair cut every week.

It really depends on whether there is an ideal precise length (54.72 mm) or whether there is an ideal range (between 50 and 60 mm).
If you have an ideal range then your hair never need be other than the right length, it is only if you have a precise length that you have the always too short or too long problem.

I was going to say the same thing Josh, again more so for men I think as well. Personally, my hair looks best from about week 1 through week 3 after a hair cut, then again for another two week period around week 6, after which it starts to become unmanageable.

What if you got a haircut every day/week though and it was always at, or very very near, optimum length?
Posted by: Sean at Dec 7, 2006 2:57:03 AM
I don't think length is the right metric for measuring the utility of hair. Men usually get haircuts to look "clean". When you get your hair cut too short, it will grow "messy" in about the same time as when you get it cut "just right".
If you get to enjoy the clean look for the same amount of time (3 weeks in my case), why not enjoy it with the right length of hair?
PS: I suspect length is not the right utility metric for women either. It is probably style, or a coiffured look or something similar.
