Answer:
The correct answer is Worker productivity
Step-by-step explanation:
The productivity of work is the efficiency of the productive activity of men expressed by the correlation between labor expenditure (at the level of society, of a branch, of a company or of a single worker) and the amount of material goods produced (established in money or in kind) in a unit of time. It is determined by the amount of time invested in developing the production unit or by the amount of production manufactured in the time unit. The level of labor productivity is a very important index of the progressive nature of a mode of production of a given social regime. Every new social regime, Lenin said, beats the one that precedes it by achieving greater labor productivity. Raising labor productivity means saving live work and social work, that is, reducing the socially necessary time to produce the unit of merchandise, reducing its value. The proportion of living labor decreases while the proportion of past (materialized) labor increases relatively and in such a way that the overall sum of work locked up in merchandise is reduced. This law manifests the decisive meaning of the progress of the technique for the growth of labor productivity.
