Mises analysis stated that economic calculation is only possible using market prices. In Socialist economies, the pricing system is deficient due to the public ownership of the means of production. Capital goods cannot be rationally priced because they are merely internal transfers. When left unpriced, planners will not know wow to allocate available resources.
Mises was considered the first to introduce the 'economic calculation problem' as a criticism of using economic planning instead of market-based allocation of the factors of production.
