Those scholars who reject the neoclassical viewpoint consider the benefits of STP that the USSR itself adduced. One is the ability to control for externalities directly in the pricing mechanism.[9] Another is the total capture of value obtained in STP which is neglected in market economies.[10] By this it is meant that while a worker might put in a certain amount of work to produce a good, a market might value that good at less than the cost of labor the worker put in, effectively negating the value of the work done.
