The returns from public investment, especially during periods of scaling up, are often lower than expected. To understand the mechanisms behind this regularity we exploit original information on investment projects obtained from World Bank project reports to document the extent and the drivers...

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...

Do 'local' methods of evaluation, such as partial equilibrium analysis at market prices or estimation of shadow prices, provide reliable assessments of a large rural roads programme's social profitability? Consider a small open economy with one city and a rural hinterland, two traded goods, two...

In benefit-cost analysis, we accept that a future dollar is worth something less than a dollar today. However, we do not have a clear method to apply social discounting in retrospective benefit-cost analysis. In this note, we will first develop the case for using historical borrowing as the...

Decentralizing the allocation of public goods by giving funds directly to communities takes advantage of local information concerning needs, but decreases the accountability over how funds are used; leaving funds open to misuse or capture by local elites. In Indonesia, the World Bank attempts to...

We provide a comprehensive survey of the recent literature on the link between productive government expenditure and economic growth. Starting with the seminal paper of Robert Barro (1990) we show that an understanding of the core results of the ensuing contributions can be gained from the study...

Public-private partnerships (PPPs) involve the supply by the private sector of infrastructure and services deriving from infrastructure assets which have traditionally been supplied by the public sector. PPPs are spreading all over the world. It may be quite plausible that such arrangements were...

The quality of goods provided by public utilities depends on infrastructure features and operational inputs. I compare the economic efficiency that results from price ceilings and minimum quality standards (i.e., compliance with environmental, chemical, and performance standards and norms)...

Explication of reality may draw tools outside the phenomenon. That is the essence of case study, and the epistemological motivation of this paper. The paper illuminates the space of PPP policy in the UK. Yet, that illumination raises questions that stand to guide other countries, and the paper...
