To try and avoid some potential confusion... I should mention that I took the liberty of naming these rules. It makes it easier to talk about them when they have names. I'm not very clever though so I simply named them after some of my favorite economists. James Buchanan was a Nobel Prize libertarian economist, John Quiggin is a liberal economist and Alex Tabarrok is a libertarian economist.
So here are their rules...
Buchanan's Rule: Using a resource one way means sacrificing the other ways that it could also be used
A nation cannot survive with political institutions that do not face up squarely to the essential fact of scarcity: It is simply impossible to promise more to one person without reducing that which is promised to others. And it is not possible to increase consumption today, at least without an increase in saving, without having less consumption tomorrow. Scarcity is indeed a fact of life, and political institutions that do not confront this fact threaten the existence of a prosperous and free society. - James Buchanan, Richard Wagner, Democracy in Deficit: The Political Legacy of Lord Keynes
Eisenhower probably put it best...
Every gun that is made, every warship launched, every rocket fired signifies, in the final sense, a theft from those who hunger and are not fed, those who are cold and are not clothed. This world in arms is not spending money alone. It is spending the sweat of its laborers, the genius of its scientists, the hopes of its children. The cost of one modern heavy bomber is this: a modern brick school in more than 30 cities. It is two electric power plants, each serving a town of 60,000 population. It is two fine, fully equipped hospitals. It is some fifty miles of concrete pavement. We pay for a single fighter plane with a half million bushels of wheat. We pay for a single destroyer with new homes that could have housed more than 8,000 people. This is, I repeat, the best way of life to be found on the road the world has been taking. This is not a way of life at all, in any true sense. Under the cloud of threatening war, it is humanity hanging from a cross of iron...Is there no other way the world may live? - Dwight D. Eisenhower
Quiggin's Rule: Society's limited resources should be put to more, rather than less, valuable uses
Even at the cost of lining up with [Tom] Friedman, I’d be pleased if the idea that war is a mostly futile waste of lives and money became conventional wisdom. Switching to utopian mode, wouldn’t it be amazing if the urge to “do something” could be channeled into, say, ending hunger in the world or universal literacy (both cheaper than even one Iraq-sized war)? - John Quiggin, War and waste
Tabarrok's Rule: Actions speak louder than words
Overall, I am for betting because I am against bullshit. Bullshit is polluting our discourse and drowning the facts. A bet costs the bullshitter more than the non-bullshitter so the willingness to bet signals honest belief. A bet is a tax on bullshit; and it is a just tax, tribute paid by the bullshitters to those with genuine knowledge. - Alex Tabarrok, A Bet is a Tax on Bullshit
In my opinion, these rules are all good rules. I think it's beneficial when we abide by them and harmful when we don't.
What do you think? Are these rules worthwhile or worthless? Do you know of any other economic rules that are more worthwhile?
