  We investigate Kantian equilibria in finite normal form games, a class of
non-Nashian, morally motivated courses of action that was recently proposed in
the economics literature. We highlight a number of problems with such
equilibria, including computational intractability, a high price of
miscoordination, and problematic extension to general normal form games. We
give such a generalization based on concept of program equilibria, and point
out that that a practically relevant generalization may not exist. To remedy
this we propose some general, intuitive, computationally tractable,
other-regarding equilibria that are special cases Kantian equilibria, as well
as a class of courses of action that interpolates between purely self-regarding
and Kantian behavior.
