THE results of the preceding survey of the aggregative
variables in Central Africa's money economy provide an
unmistakable demonstration of the rapid pace of its ex-
pansion. But an adequate understanding of the forces at work
within the money economy cannot be obtained from analysis
of these macro-economic categories alone. A micro-economic
inspection of individual components of the money economy can
offer further insights into the problems and prospects of
development. For this purpose, the money economy may be
subdivided into sectors. Each has its own peculiar properties.
Nor are the various sectors uniform in their analytical signific-
ance. Developments in some sectors have initiated and shaped
the overall pattern of expansion, while in others the level of
activity has been more a by-product of the general process of
expansion itself.

For the sake of convenience, four components of the money
economy may be isolated for separate discussion: mining,
agriculture, manufacturing, and the public sector. Lines of
demarcation between these sectors cannot always be unambigu-
ously drawn. This problem arises particularly with the public
sector. In one fashion or another, public expenditures have
influenced the performance of the mining, agricultural, and
manufacturing industries. But public expenditure on social
overhead capital -- an important aspect of the development
problem in itself -- has made a major contribution to the growth
of the money economy. Separate treatment of this type of
activity will, therefore, be undertaken.

Mining has always been the mainstay of the money economy
in the Rhodesias. Indeed the geological riches of the area
provided the primary rationale for European enterprise and
