Toilet Seat Rules: Why you Shouldn't Care

This paper analyzes the issue of choosing a socially efficient rule on how to leave the toilet seat. Leaving the seat as it is after usage is found to be the best rule over a wide parameters space. Using a loss function minimization approach, factors such as relative toilet usage, frequency of the down position, relative gender importance and cost elasticity to seat movements are considered. Leaving the seat as it is after usage proves to be dominating a large set of other rules that entail no strategic interaction.
