Unfortunately, Mr. Littmann did not extend his analysis further by mentioning Mises’s calculation argument, and Mises’s discussion of this issue in his 1920 article “Economic Calculation in the Socialist Commonwealth” and in Human Action. While Hayek’s analysis of socialism’s information problem is important, arguably socialism’s most fundamental problem is its inability to economically calculate. The inability to transmit information and the inability to calculate, while to a degree related, are not the same, and the calculation problem, from a praxeological perspective, can not be subsumed under the knowledge problem. To be able to gauge the rationality of contemplated future, as well as past, actions individuals must be able to calculate, and in a market economy this is achieved through the use of money prices. In particular, the appraisement, through calculation, of future contemplated action is a distinct issue from having access to information (“knowledge”) that is scattered and fragmented. I know this topic has been significantly debated within the Austrian School, but the above is my briefly stated understanding of the issues.
