A few years ago I wrote a paper on Hayek and Rawls (ungated early version here). This, plus teaching a course on libertarianism, led me to the early 20th century University of Chicago economist Frank Knight. One of the points of commonality between Hayek and Rawls is their scepticism about desert as the basis for social institutions. This scepticism owes much to Frank Knight. Rawls cited Knight’s 1923 essay “The Ethics of Competition” in the discussion of desert from A Theory of Justice, and in an earlier essay cited Hayek, who in turn cited Knight. Knight is remembered as one of the founders of Chicago economics, and thus indirectly one of the fathers of free market fundamentalism. He was indeed a teacher / colleague of both Friedrich Hayek and Milton Friedman. Yet Knight was a fierce critic of what he took to be bad, simplistic arguments for laissez-faire, chief among them the view that by distributing income according to marginal product the competitive system rewards the deserving. Knight didn’t deny that marginal productivity explained the distribution of income, he just denied that reward according to marginal product was ethically important, in itself. Hayek and Friedman had essentially the same view. The virtue of reward by marginal product is efficiency, not fairness. It’s surprising, then, to read that neoliberalism teaches that markets reward the deserving. I posted about this earlier, but now I have a paper on the topic forthcoming in PPE. It’s called “Markets, Desert, and Reciprocity,” but its subtitle could be “Knight, Hayek, Friedman, and Rawls (vs. Bell, Nozick, Sandel, etc.)” The final section includes some discussion of the reciprocity objection to proposals for an unconditional basic income.
