Economics and philosophy

I am reminded of Paul Heyne's emphasis on the point that moral energy is scarce like all other resources, with the implication that it is best to rely on incentives when possible, and to save the moral energy for contexts in which incentives perform poorly. One can think of "pure" communism / communitarianism as an attempt to rely entirely on moral energy for allocation. That moral energy is scarce is then why it fails.
