This paper re-examines the validity of using expected values to evaluate the social profitability of public investments under uncertainty. Departing from the usual assumption of an aggregate good, the setting is a small open economy that faces stochastic world prices for tradable goods and...

This paper makes the case for the systematic appraisal of public sector projects using shadow prices as the signals of social scarcities. In so doing, it attempts to redress the balance between estimating inputs and outputs, central though that task is, and valuing them correctly. The account of...

Survey-based tools for determining inequality in Africa south of the Sahara have been critiqued for being too expensive, and oftentimes unsuitable to the realities of the region. The need for a reliable alternative for determining wealth distribution, from which data can be generated for policy...

The level of income can be directly inferred from the level of education, making education an important variable as a key determinant of better livelihoods and poverty alleviation. However, in most developing countries education is not accessible to all. In Ghana - although basic education is...

Donors face distinct challenges in operating in fragile states and supporting the building of state capacity. This paper explores one type of assistance - the 'embedding' of highly-skilled staff members within local government agencies - through a unique case study of Finn Church Aid's...

This paper describes the results of an impact evaluation of the National Solidarity Programme, a community-driven development programme in Afghanistan that created democratic village councils and funded small-scale development projects. Using a randomized controlled trial across 500 villages, we...

Randomized controlled trials (RCTs) are now widely used in development economics. However, their use is often resisted by non-governmental development organizations. The objections they raise differ between the three types of activities of such non-governmental organizations (NGOs): capacity...

Do urban agglomeration economies enhance the social profitability of rural roads? When all goods are traded at parametric world prices, lower transport costs benefit villagers. Urban activities and welfare are unaffected if labour is immobile, but their levels fall when rural workers move freely...

In the presence of agglomeration economies, the effects of a rural roads programme depend not only on the reduction in transportation costs, but also on the form of labour mobility. When financed by a poll tax on rural households, the wage will rise, accompanied by some return migration,...

The structure employed is a small open economy, with one city and a rural hinterland, two traded goods, a transport sector, two specific factors, and mobile labour. A socially profitable programme will promote not only internal, but also external trade. Theory and numerical examples indicate...
