A cost-benefit analysis of landmine clearance in Mozambique

After reviewing the nature and extent of the landmine problem in Mozambique, this article applies cost-benefit analysis to landmine clearance in that country. The main benefits of clearance are saved lives, injuries and medical costs and the agricultural output that is not lost if landmines are cleared. A very large negative net present value was estimated, a result explicable by the high costs of clearance, the relatively small number of people killed or injured by landmines and the low value of agricultural productivity per hectare. The article concludes with a discussion of the role of the economist in analysing such issues and suggests some alternative areas in which financial resources would provide a greater positive impact on the welfare of Mozambicans.     

Project evaluation and social‐cost benefit analysis in LDCs: Awkward issues for a useful approach∗

This paper outlines some limitations of social cost‐benefit analysis (CBA) and reviews the advocacy of its use in LDCs. It argues that account should be taken in social CBA of the optimality of imperfect decision‐making and the costs of information gathering and processing. This supports the view that simple may be optimal. It is pointed out that because of informational requirements and institutional factors, the technique may lead to bias against small projects, small countries and to urban bias. Furthermore, in the past the technique has overstressed the (economic) evaluation phase of the project cycle in comparison for instance, to the identification phase. The importance of taking account of environmental spillovers and externalities in LDCs in project evaluation has not been recognized in the past by a number of economic analysts but this is changing. Many criticisms of social CBA appear to be based upon unreasonable expectations about the perfectability of decision‐making. The technique has social value if it ensures that socially unsatisfactory projects are not selected and that those selected are satisfactory, if not optimal.

Investment in education in developing nations: Policy responses when private and social signals conflict

In most developing countries the net private benefit of higher education exceeds its net social benefit because education-related wage differentials are excessive and the beneficiaries of higher education are subsidized. The resulting political pressures seem to favor investment in education over the creation of employment opportunities. A more balanced allocation of investment may require the revision of basic policies dealing with wage determination, the incidence of educational costs and the role of private sector education. The aim should be narrow the gap between private and social signals and thus reduce excess private demand for higher education.
