Table 1 below contains estimates of the contribution by the public sector to monetary Gross Domestic Product in 1970 as presented by Erick Svendsen. These include the central govern- ment as well as parastatals but the contribution of the former to any but water and the last three categories is likely to be negligible.

Finance, Real Estate 46 Public Administration 100 Education and Health 77 Other h) 33 On this assumption the contribution of the parastatal sector proper to total monetary GDP in 1970 was less than 18 % overall. The main reason for this is that the two largest sectors, agriculture and commerce, continue to be dominated by private individuals and companies. There has been some change since 1970 par- ticularly in real estate, construction, manufacturing and to a lesser extent, trade, but even then the overal share of the parastatal sec- tor is unlikely to be in excess of 25% . This is also approximately their relative importance in total employment and in the total wage bill (about 24% in each). The real significance of the parastatals lies in their role as in- vestors. In 1971 they accounted for 43 % of total gross domestic capital formation — a sharp rise from the 35% level of 1970. Allowing for unusual fluctuations in stock holdings in those years 4
