1. I always get wrapped around the axle on pricing discussions - will x offset y? How will different groups react? I'm not crazy! It is hard and the effects do sometimes totally offset. Radically changing your pricing may in fact have absolutely no effect whatsoever. Whoa!
2. I wish more companies would publish results like this and we didn't have to rely on the occasional (though terrific!) academic study. I'm sure Amazon runs experiments like this all the time.
3. I feel genuinely bad about the mobile game industry and how these "high value customers". Maybe I'm making a bad assumption but it seems unlikely these folks are the idle rich spending their spare thousands on gold bars.
4. There might be metrics in your business that are much harder to move than you would think. Local maximums that might be very hard to change.
Terrific, terrific study. Kudos to King for this, at least.
