^{Page 439 note 2} The tendency would be even more striking if the figures in Tables 3 and 4 were at constant prices.

^{Page 441 note 1} An explanation of some of the terms used here may be useful to the general reader. Opportunity cost is the term used by economists to express cost in terms of forgone alternatives. For instance, if a packet of cigarettes costs 4s. and a bottle of beer 2s. the opportunity cost to an individual of a packet of cigarettes is two bottles of beer. Thus the social opportunity cost of building a university would be what society has to give up in order to do it. In evaluating an economic development project, there are two reasons why it may be misleading to use the market price of an input as a measure of its social opportunity cost: (i) Market prices may not reflect current scarcities—i.e. there may be fundamental disequilibrium in certain markets (examples are given in the text); or (u) if the project is a large one it may itself affect the value of inputs. Therefore accounting prices are often used for this purpose. Where the aim is to maximisc the ratio of the present value of benefits to the present value of costs, the accounting price of a resource would be defined as equal to its marginal social opportunity cost.

To derive a unique, consistent set of accounting prices it would be necessary to construct and solve a programming model of the economy as a whole. In practice, accounting prices and indirect effects may have to be estimated in an ad hoc way. Intelligent adjustments based on guesswork may be preferable to leaving market prices alone. Probably the best way to bring accounting prices into the analysis, as has already been suggested, would be to make several calculations of cost and benefit on varying assumptions about the divergence between market prices and accounting prices of inputs and outputs.

^{Page 445 note 1} To get the private sector to respond in the required way, a tax per high-level employee equivalent to the cost of training would need to be imposed. The idea here would be to reduce the gap between the Cost to the employer and the social opportunity cost.

^{Page 449 note 2} Lack of data has precluded adjustments for indirect taxes and subsidies. The former should strictly be cut out, the latter added, to give a truer reflection of the opportunity cost of both current and capital expenditure.

Some have suggested that buildings and equipment may have a shorter life in tropical conditions, but the high expenditure on maintenance (see above) and the slower rate of obsolescence are likely to offset the effects of the climate.

^{Page 451 note 1} It is arguable that the planners chose too low a rate of interest, although Okigbo (op. cit.) advocates the use of the long-term rate on government bonds for this purpose. At any rate various rates can be experimented with. It may even be felt that that part of the capital that comes from abroad in the form of grants has zero opportunity cost to the Nigerian economy, in which case a zero interest rate for that part of the capital could be used.

^{Page 452 note 1} The following formula is used to convert capital expenditure into equivalent annual cost:

where R is equivalent annual cost, P is initial investment, L is amount recovered at end of period, n is estimated lifetime, and r is discount rate (social opportunity cost of capital).

^{Page 454 note 1} To be precise, looking at the local university first, cost per graduate can be defined in the following way:

where C is average cost per student per annum, g is number of graduates in year t, Cg is cost per graduate in year t; u, v… nare groups of graduates in year t classified according to number of years spent at university, and s', w'… n' are groups of unsuccessful leavers in year classified according to number of years spent at university. For students abroad, what is needed is an estimate not of cost per graduate in year t, but of cost per graduate returned to Nigeria in year t; To make this calculation simpler, the assumption is made that a student abroad ceases to be a significant cost to the Nigerian economy as soon as he ceases to be a student, even if he remains abroad—on the principle that he is unlikely to receive further net remittances from home (and may even become a net remitter, thus offsetting the excess of production forgone over maintenance cost avoided). The cost per returned graduate can be precisely defined as follows:

whereg' is number of graduates returned home in year t, c' is average cost per student abroad, K is average outward travel costs (including dependants), K' is average homeward travel costs (including dependents), is proportion of travel costs borne by the Nigerian economy, Cg' is cost per graduate returned home in year 1, a… n are groups of graduates returned home in year classified according to the periods over which they have been a cost to the Nigerian economy, and a'… n' are groups of unsuccessful students returned home in year t, classified according to the periods over which they have been a cost to the Nigerian economy.
