This has been bouncing around my head since reading "why I can't stand white belly dancers".

And as a post-post-script (I know this trails a long FB thread), I recommend Black Girl Dangerous and Ta Nehisi-Coates as two different feeds to follow.

We all perceive the world through different lenses. Vischeck helps me understand/anticipate how a red-green colorblind person might see something. Similarly, TNC and BGD good starting points for understanding these other perspectives, and sometimes (I hope) you'll find yourself thinking "I hadn't considered that issue".

Arthur Chu made a lot of important points, including the point that angrily calling "bullshit" doesn't make him wrong (and might sometimes be an effective approach). It's hard to avoid the short term focus of "winning the argument". TNC reflected on this recently - http://www.theatlantic.com/politics/archive/2014/04/race-culture-and-poverty-the-path-forward/360081/http://www.theatlantic.com/personal/archive/2014/04/he-hated-error-more-than-he-loved-truth/360329/

Can we switch to having accurate price tags already?

I really wish all price tags included tax, like they are everywhere else in the world I've ever been.  As far as I can tell it's actually illegal in most places in the US.  I've seen places try to quote post-tax prices (Tosci's in the MIT student center back in the day come to mind, they included odd-looking prices on the list that were round after tax).  But they stopped, I think because they were smacked down.

Which of course brings to mind the question of unreachable round prices.  Are there nice round numbers that can never be the after-tax price of something subject to sales tax?  I believe the answer is "yes", but I forget the rounding rules (which probably vary by state just as much as the rates themselves).

When I write things on a computer I'm very systematic, past the point where it's immediately useful, partly because my future self might want to process the data in an automated fashion.

Just to be clear, the second paragraph of Jeff's post is his Amelia Bedelia-style humor, not our actual practice.

When should we limit an activity with a ban instead of a tax?

There's also an interesting distinction between a tax as a market mechanism, and a cap-and-trade: it turns out which is the better regulation depends on the form, volatility, and the relative uncertainty of the cost & damage functions. A damage function with a strong threshold makes a cap the right approach. If the damage function is more uncertain than the cost function, generally means a tax makes more sense (and vice versa).  If the cost function is volatile year-to-year then a tax also makes sense. etc.

With metered pricing it's hard to know how expensive choices are.

It would be interesting to do a version of this post with numbers that included full social costs.
