The educational composition of the
labour force:
An international comparison
George PSACHAROPOULOS
and Ana Maria ARRIAGADA *
Policy-makers and analysts typically use differences between the school
enrolment ratios of different countries or regions to justify educational
investment. (For the example par excellence in this respect see Harbison and
Myers, 1964.) In this article we argue that although the enrolment ratio is a
readily available statistic, it may not be the most appropriate indicator for
setting investment priorities in education. Instead we have compiled and
present here statistics on the educational composition of the labour force,
which we believe constitutes a more sensitive human capital index.
Flows versus stocks
At any given point in time, a country's productive capacity is largely
determined by its factor endowments, such as the area of land under
cultivation, the amount of installed physical capital, the size of the labour
force and the amount of human capital embodied in the labour force. Such
stocks of productive resources change over time as a result of investment
flows, e.g. the stock of physical capital is augmented each year by the flow of
net investment in new machines. In a similar fashion, the human capital stock
is changed by the net additions to the labour force of the flow of graduates
from the educational system.
The difference between educational stocks and flows is perhaps more
important than in the case of other factors of production for the following
reasons:
(a) the time-lag between investment in education (say, as measured by
enrolments) and additions to the human capital stock is longer than in
any other sector;
(b) some investment in education may never translate into additions to the
human capital stock because of losses in the process (e.g. graduates not

of the authors and should not necessarily be attributed to the World Bank.
