Productivity Analysis

A systematic survey of the market situation requires first of all the forecasting of such an important

index as productivity.

By productivity we mean the relationship between the output of goods and services and the inputs of

resources (factors of production) used to produce them. Productivity is usually measured by ratios of

changes in inputs to changes in outputs using index numbers. For example, changes in labour productivity,

the most common measure, are measured by an index of man-hours divided into an index of

output. If the production index stands at 150 (1990 = 100) and the index of man-hours worked stands at

125, then the labour productivity index stands at 120, i.e. labour productivity has increased by 20 per

cent over 1990 levels. This is known as a partial productivity index, and it does not, in fact, measure

changes in the productivity of labour alone unless inputs of land and capital have remained constant.

The calculation of total factor productivity is difficult in practice since the proportions of the

different factor inputs do not remain constant over time and their individual contribution to output

change is difficult to disentangle. Comparisons between labour productivity in different sectors of

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

1. inputs — затраты

2. 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)

3. a partial productivity index — частичный индекс производительности

4. man-hours — трудозатраты в человеко-часах

5. labour productivity — производительность труда

6. to disentangle — определить (распутать)

7. capacity utilization — использование производственной мощности

8. the underlying trend of productivity growth — направление (тенденция), лежащее в основе

роста производительности

9. real per capita income — реальный доход на душу населения

10. marginal productivity — предельная производительность

17.7.2. Match the following terms with the correct definition

Work with a partner.

1. law of one price

2. price system

3. factors of production

4. turnover

5. capital-intensive

6. labour-intensive

7. per capita income

a) The total sales revenue of a business.

b) The production of a commodity in which a higher proportion

of capital is used in the mix of inputs compared with other

factor inputs, such as labour.

c) Income per head, normally defined as the national income

divided by the total population. International comparisons

of per capita income at current exchange rates need to be interpreted

with caution.

d) The mechanism which sends prices up when demand is in

excess and prices down when supply is in excess.

e) The inputs or resources used in the process of production.

Land, labour and capital are the three main headings used in

the analysis of the factors, with entrepreneurship often counted

as a fourth.

f) The law, articulated by Jevons*, stating that “In the same open

market, at any moment, there cannot be two prices for the

same kind of article.” The reason is that, if they did exist,

arbitrage should occur until the prices converge.

g) A production technology for which relatively more labour
