Economic Tenets

Those teaching introductory economics courses should always try to focus on the most important tenets of economics. At Cafe Hayek they do a good job of citing Arthur Sheldon's list of these tenets...

I might add the finding that two people, two groups, or two countries can never be made worse off from trade. I guess the cite for that would be Marshall.
