#1 on prefiguring of the so-called Coase theorem, consider also p. 396-7 of W.H. Hutt, “Co-ordination and the Size of the Firm,” South African Journal of Economics 2(4), December 1934:
“Now, under one ownership, their relations would, given competitive institutions, be exactly the same, provided that both methods were equally efficient from the social standpoint. There is no reason why the spreading of the lines of responsibility back to several sources should lead to less effective planning than subordinacy to an authority emanating from one source, given the equal availability of relevant knowledge to the managers who devise the plans…The most important significant difference between the two cases is that, in practice, in the one case there may not be the availability of relevant knowledge that there is in the other.”
That is from Daniel B. Klein. And:
For a still earlier ‘discovery’ with transaction costs and all see my former colleague Yehoshua Liebermann’s “The Coase Theorem in Jewish Law,” Journal of Legal Studies, Vol. 10, No. 2 (Jun., 1981), pp. 293-303
That is from Moshe Syrquin, link for both here.
