Nevertheless, I think that defining “monetary calculation” is somewhat difficult. We can possibly imagine lots of societies, with varying degrees of “monetary calculation” in them. Maybe a barter economy, in which at least one commodity is developing into a common medium of exchange, has some (low) level of monetary calculation. We may also say the same about some sort of a market-socialist economy. And the degree of monetary calculation can come to its full expression only in the case of a “pure and unhampered” market, that is, a purely libertarian society in which private property rights are the rule. This is also consistent which the One Big Firm (as Rothbard puts it) imaginary model, in which an enterprise is the owner of all the means of production in a given economy, and where monetary calculation does not exist at all (or it is useless).
well one way to maybe think about it is to consider those individuals who have begun to trade the commodity as money as being participants in a fully ‘market economy’, and those bartering and not valuing the commodity as money are simply not direct participants in that market, and only have indirect effect on that market by virtue of the barter trades they make with those who are within the market economy. As money becomes more widely accepted the arena comprising no-money barterers involved in non-economic action shrinks and a money economy grows and takes over the whole arena (or market in the ‘broadest sense’)
