Analysis of information sources in references of the Wikipedia article "Planification économique" in French language version.
« Centralization is commonly identified with plan and decentralization with market, but there is no simple relationship between the level of decision making and the use of market or plan as a coordinating mechanism. In some economies, it is possible to combine a considerable concentration of decision-making authority and information in a few large corporations with substantial state involvement and yet to have no system of planning as such… To identify an economy as planned does not necessarily reveal the prevalent coordinating mechanism, or for that matter, the degree of centralization in decision making. Both depend on the type of planning mechanism. »
« Planning is not equivalent to ‘perfect’ allocation of resources, nor ‘scientific’ allocation, nor even ‘more humane’ allocation. It simply means ‘direct’ allocation, ex ante. As such, it is the opposite of market allocation, which is ex post. »
