Pretty sure if you re-post something already on HN the post is redirected to the original. Now I see you changed the title "Setting Pricing For A Startup" to "Setting Pricing for a Startup - The Rule of 80%" so it appeared on a different url?
there's an apocryphal tale that Cadillac sales actually went down in the 1980s when Cadillac lowered prices.
I think you always have to be careful not to mix correlation with causation. The slump in Cadillac sales could have been dure to the poor edonomic times. Black Monday anyone?
Cadillac tried to compete with Lexus and Infiniti by lowering prices. Sales nosedived as the price reduction was seen as confirmation that Lexus and Infiniti made better cars.
Again, I've heard the story a number of times, but I can't prove it. Also, the 1980s were the height of Cadillac's atrocious badge engineering, where they's just throw different grilles on the same car across all the different makes.
I have a better pricing story that I'll be using on my new blog soon.
