Abstract: Even as the market seems triumphant everywhere and its laws progressively and ineluctably impose themselves worldwide, we cannot fail to be struck by the lasting topicality of the following wellknown quotation from D. North: 'It is a peculiar fact that the literature on economics ... contains so little discussion of the central institution that underlies neoclassical economics-the market' (North, 1977).)
