General Thrust

Ms. Tsakok (I) has done a useful job in summarising and commenting on the various estimates of shadow prices which appeared in the symposium on shadow pricing in Pakistan, published in the Summer 1979 issue of this Review. However, her discussion of my paper in the symposium (3) 1 is misleading regarding a number of points of detail, and, more seriously, obscures the general thrust of the argument. Considering the detailed points first, Ms. Tsakok is concerned with a comparison of the values of the key shadow prices given in the different studies as well as with the explanations for the variations between the different estimates. However, JW discusses not the estimation of a set of shadow prices for Pakistan, but the broader question of the implications of the use of an income-weighting system, described conventionally as 'social' analysis, in project appraisal. The shadow prices attributed to my work in Table I of Ms. Tsakok's paper (II are not in fact contained in JW. but are taken from an earlier mimeographed paper written in 1977. These shadow prices are preliminary estimates, which are not used in my more detailed study on cost benefit analysis in Pakistan [2]. Furthermore, It is strange to find these estimates cited, since they conflict with the analysis of JW, which is the paper under review.

Evaluation Techniques

- This is a review article based on 40 years of experience in the field of policy and project appraisal and evaluation. The author has had an extensive career in this area in the World Bank, the European Commission, Italian Government Ministries and in academia. The review concludes that cost benefit analysis extended to "real options" and applied jointly with the "effects method" helps solve certain critical issue of traditional financial and economic appraisal and evaluation techniques. More significantly, it contributes to better integrate financial and economic evaluation and appraisal techniques with organizational and sociological evaluation techniques. Key words: appraisal, evaluation, World Bank, distribution weights.

Second Use

The wetland areas of England are under imminent threat of drainage for agricultural improvement. The immediate cause is the local drainage surveys produced under the Water Act 1973. Problems identified in these surveys are subjected to cost-benefit appraisal. Examination of a selection shows that these appraisals are technically defective and result in an overstatement of the benefits and in an overinvestment in land drainage. The main defects are: first, a failure to assess amenity and conservation losses; second, use of prices that contain a substantial element of income transfer which is not netted out; third, a failure to properly calculate the rate of land conversion—a crucial variable; fourth, the project appraisal period is arbitrarily chosen or treated as a variable; fifth, the use of theoretical rather than expected agricultural yields; sixth, the level of flood protection aimed at is too high for the stated objective; and, last, anticipated flood losses are not deducted.

Special Circumstances

Public project appraisal using cost-benefit analysis (CBA) requires analysts to project risky net benefits and to convert these into present values using a social discount rate (SDR). We consider which types of risk matter for CBA. For small projects with only idiosyncratic risks, expected net benefits should be discounted at a risk-free SDR. If projects are large or expected net benefits are correlated with aggregate consumption, the alternatives are to replace expected net benefits with their certainty equivalents (CEs) and to discount these at a risk-free SDR, or to discount expected net benefits using a higher SDR that includes a risk premium. These methods are equivalent under special circumstances that are unlikely; the first approach is the correct one. We examine when replacing expected values with CEs will matter, and how this might be done. For most projects, analysts should discount expected values of net benefits at a risk-free SDR.

Non Market Valuation

Extensive non-engineered landfilling practice in developing countries has raised environmental concerns, but operating a sanitary landfill appears infeasible due to financial incapability. This study aims to determine the feasibility of a sanitary landfill project by including its environmental values into the project appraisal while simultaneously applying three policy-relevant methods—non-market valuation, benefits transfer, and cost-benefit analysis—in two study areas in Peninsular Malaysia. The non-market valuation study used choice modeling, a questionnaire-based technique, to elicit willingness to pay among 624 households toward the environmental attributes of the sanitary landfill. Their responses resulted in the monetary values of the environmental attributes by referring to implicit prices of leachate discharge, bad odor, disease vector and view. The implicit prices of bad odor (RM2.29 per month) and view (RM3.59 per month) in the two study areas were transferable and used as a proxy of additional solid waste disposal payment in environmental cost-benefit analysis. Positive net present value offers empirical evidence of the feasibility of the sanitary landfill project. The findings show that the inclusion of environmental values in project appraisals increases the chances of implementing sanitary landfills, providing a new approach to address the environmental concerns in developing countries. Future research should consider the external costs along with the external benefits to allow for a comprehensive comparison between environmental values in environmental cost-benefit analysis.

The Right

An investment project has effects on the incomes of households, firms and government , not only directly through the value added produced by the project it9Cif, but also by inducing additional output through inter-industry linkages and expenditures out of the extra incomes accruing to its beneficiaries. The latter, sometimes called the "multiplier" or "downstream" effects of a project , have been discussed in some of the recent literature on social cost benefit analysis [6, II]. These contributions have been concerned with the "multiplier" or "downstream" effects of projects, and with the derivation of shadow prices which capture all such effects in full. If these shadow prices are correctly calculated, so it is asserted, then valuing a project 's direct inputs and outputs at these prices yields the right measure of its social profitability . This approach is in the spirit of, and consistent with , that of the various manuals on social cost• benefit analysis [9. 13, 16] .
