flfe R e TR YA while the secondary criteria are ranked in the following order of importance: (a) employment (b) location (c) industrial linkage (d) budgetary impact (e) investible surplus. It is immediately apparent that as operational guidelines these criteria are of little value. In what way can primary criterion (a) be said to differ from secondary criterion (¢) assuming that the N.D.C.’s prime objective is NOT to maximise profit outflow over- seas? What meaning can be attached to national cost/benefit if it is not commercial profitability adjusted for the social valuation of foreign exchange effects, employment, linkage, location and budgetary effects? The secondary criteria are therefore implicit in primary criterion (b). Furthermore how much weight is to be at- tached, in money terms, to the ‘social’ considerations? As Penrose has put it: ‘In weighing these criteria in any given case the dif- ficulty of course lies in the nature of the ‘trade-off’; how much to sacrifice employment to improve industrial linkages, or location to increase investible surplus, etc.’*® But this is not a difficulty which can be resolved at the level of the individual parastatal; the weight to be attached to each criteria must be determined nationally and applied uniformly to all investment decisions in the economy. The real power of such criteria in the planning process lies in their being used to rank alternative projects in a consistent manner and this cannot be done if the weights are not specified or if each in- vesting body is applying a different set of weights. So far the Planning Ministry and the sectoral ministries have failed to produce investment or more generally, spending criteria of any sort. Parastatals have therefore been left to analyse projects as best they could. As a result there has been little if any ranking of projects within parastatals and almost no ranking of projects between parastatals and government. The allocation of resources has therefore been extremely arbitrary and if any criterion has been used at all it has been that of commercial profitability. The situation is, however, changing and the recent budget and balance of payments problems have been instrumental in bringing about a greater concern for the way in which investment allocations are made; but this concern has not gone as far as the formulation of 18
