The economy, for example, between capital-intensive manufacturing and labour-intensive services,

Need to be interpreted with care for the same reason. Another problem in productivity calculations

Is that the quality of unit inputs may vary; for example, the use of more highly trained labour

May lead to higher output without any increase in the number of man-hours. Since changes in

Productivity are affected by the level of capacity utilization, the underlying trend of productivity

Growth may be very different from that indicated by short-term movements in productivity indexes.

In the long run productivity advance is the main cause of increases in real per capita income.

(The measures mentioned relate to average productivity; marginal productivity is the change in

Output caused by an increase or decrease of one unit of the factors of production.)

Commentary and Notes to Text 17.7.1.5

Inputs — затраты

Productivity is usually measured by ratios of changes in inputs to changes in outputs using index

Numbers — производительность обычно измеряется соотношением изменений в затратах

И изменений в выпуске продукции с использованием числовых индексов (показателей)

A partial productivity index — частичный индекс производительности

Man-hours — трудозатраты в человеко-часах

Labour productivity — производительность труда
