A market for ideas may be commonly viewed, more or less metaphorically, as the infrastructure of cultural life. The cultural welfare of a community depends on the "production and exchanges of ideas", be them science- or arts-based, which, besides symbolic signalling, exhibit the same economic properties as the goods and services they are embodied in. A market for ideas may be, in a sense, "priceless", since it may be relying on a somehow different kind of "value standard" ("truth-, goodwill-, beauty-, virtue- seeking") than the "mundane" intangible serviceability of tangible goods, but, in another sense, it uses labour, nature and capital, transformed and traded, all this in a world of scarcity where institutions (property rights) and (money) prices do matter. This paper will briefly explore on the genus proximum et differentia specifica regarding the work of the markets for ideas, on the one hand, and of the markets for goods, on the other hand, recollecting judgments on: a). the logic of "property rights" and of "pricesignals" (within such markets for ideas); b). the logic of freedom vs. regulation in markets for ideas (affected by "risks of failure"); c). the logic of national culture building, cultural awareness and cultural mimetism, in the case of Romania and the criticisms raised against the immaturity of its markets for ideas (as basic fundaments of cultural environments). We'll add, in a diachronic dialogue, under the aegis of paralleling the markets for ideas and those for goods, inter alia, F.A. von Hayek, R.H. Coase, T. Maiorescu, and H.R. Patapievici.
