Bryan Caplan: Excellent Libertarian; Critic of Austrianism

Dear K:

I think my friend Bryan Caplan is an excellent libertarian. I also think he is an excellent economist, except insofar as his attacks on Austrianism are concerned. I don’t want to spend time refuting the passage of his you send me, since, in my opinion, this has already been done. For some literature making this case, see below.

Best regards,

Walter

Dear Dr. Block,

Sorry for the late response.

Bryan Caplan says,

“Hans-Hermann Hoppe, arguing for Rothbard’s approach, makes a subtly stronger claim: “Pareto-optimality is not only compatible with methodological individualism; together with the notion of demonstrated preference, it also provides the key to (Austrian) welfare economics and its proof that the free market, operating according to the rules just described, always, and invariably so, increases social utility, while each deviation from it decreases it.”[21] (emphasis mine) Strictly speaking, however, Rothbard could only claim the welfare effects of government intervention upon “social utility” are indeterminate; i.e., since the victim loses and the intervener gains, it is impossible to say anything about social utility without making a verboten interpersonal welfare comparison. This is an important point, because it shows that Rothbard’s welfare economics provides a much weaker defense of the free market than usually assumed. In particular, Rothbard’s own theory strips him of the ability to call any act of government “inefficient.” By denying the ability to endorse state action in the name of efficiency, Rothbard also implicitly denies the ability to reject state action in the name of efficiency. This is no logical flaw in Rothbard’s theory (although it does reveal a logical flaw in Hoppe’s presentation of Rothbard’s theory), but it’s political implications are rather different than commonly assumed: Rothbard’s welfare criterion justifies agnosticism about – not denial of – the benefits of statism.

There is however a more serious flaw in Rothbard’s welfare economics – a flaw which again flows from his behaviorist insistence that only preferences demonstrated in action are real. Thus, Rothbard rejects the argument that the envy of a third party vitiates the principle that voluntary exchange increases social utility: “We cannot, however, deal with hypothetical utilities divorced from concrete action. We may, as praxeologists, deal only with utilities that we can deduce from the concrete behavior of human beings. A person’s ‘envy.’ unembodied in action, becomes pure moonshine from a praxeological point of view… How he feels about the exchanges made by others cannot be demonstrated unless he commits an invasive act. Even if he publishes a pamphlet denouncing these exchanges, we have no ironclad proof that this is not a joke or a deliberate lie.”[22] Indeed, Rothbard could have taken this principle further. When two people sign a contract, do they actually demonstrate their preference for the terms of the contract? Perhaps they merely demonstrate their preference for signing their name on the piece of paper in front of them. There is no “ironclad proof” that the signing of one’s name on a piece of paper is not a joke, or an effort to improve one’s penmanship.”

Now, I’m just saying that perhaps the conclusion of austrian economics is necessarily anarcho-capitalist society, because perhaps the consumers would demand a state and wouldn’t demand the NAP? What do you think about Curt Doolittle’s Propertarianism?

Dear Dr. Block,

Hi, this is K, this is my new email. I’m deleting my other ones, this will be my only one from now on. Could you tell others? I don’t know if I should email the Mises Institute about it.

Anyways, I will be responding to our last email. Sorry for the late response, I have been busy with school.

I have a question about Bryan Caplan, he says that Rothbard’s welfare economic analysis prevents him from comparing governmental action in the economy, since you could never know if anyone “consented”, or if anyone didn’t agree or agree on an exchange. I wonder if you could refute that?

From,

K
