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...

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...

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...

This paper investigates the effects of an income guarantee on borrowing to smooth consumption and finance cultivation in a risky setting with marked seasonality. A three-season, infinite-horizon theoretical model is developed and analyzed. The insights yielded by the model are then used to...

Identifies, examines, and finds remedies for three forms of potential inconsistency that can arise in the Pechman-Musgrave method of estimating the distribution of the total tax burden using microdata sets. Several variants of shifting assumptions are formulated for analysis, in which the...
