This paper recounts an early attempt to promote the adoption of high-yielding varieties (HYVs) of rice and wheat by small farmers. The instrument was a package not only of inputs, extension advice and supervision, but also - addressing risk aversion - a guaranteed net revenue. The scheme was...

The effects of a rural roads programme depend on labour mobility, how the programme is financed, and agglomeration economies. If financed by a rural poll tax and cross‐price effects and agglomeration economies are sufficiently small, the wage will rise, with some return migration. Taxes on...

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...

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...

We examine economic growth, inequality and education when the wellspring of growth is the formation of human capital through a combination of the quality of child-rearing and formal schooling. The existence of multiple steady states is established, including a poverty trap, wherein children work...

This paper studies the formation of human capital and its transmission across generations when premature adult mortality is a salient feature of the demographic landscape, either permanently or in the form of a long-period wave that follows the outbreak of an epidemic. We establish several...

An AIDS epidemic threatens Ethiopia with a long wave of premature adult mortality, and thus with an enduring setback to capital formation and economic growth. The authors develop a two-sector model with three overlapping generations and intersectorally mobile labor, in which young adults...

What is the right balance among policy interventions in order to ensure economic growth over the long run when an epidemic causes heavy mortality among young adults? We argue that, in general, policies to combat the disease and promote education must be concentrated, in certain ways, on some...

This paper investigates how families make decisions about the education of juveniles. The decision problem is analyzed in three variations: a 'decentralized' scheme, in which the parents control the purse-strings, but the children dispose of their time as they see fit; a 'hierarchical' scheme,...

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...
