Green Revolution technologies were developed and promoted in the 1960s in response to alarm about impending famine in Asia. By boosting food supplies and fostering development, the technologies were expected to create "breathing space" for completing demographic transitions there. This paper uses District-level data from rural India on agricultural transformation (from 1961 to 1981) and on changes in human fertility (from 1971 to 1981) to examine whether they did so. In a reduced form model, female literacy and marriage rates emerged as strong fertility change determinants; effects varied by age cohort. Growth in real wages in rural areas, in part brought about by HYV technologies, accelerated fertility declines. With real wage growth effects of Green... |

This paper examines the performance of the Indian seed system in the context of high volume, low value seed, using the case studies of potato and groundnut. In theory, public sector should be able to address seed needs of farmers growing these crops. However, the ability of the public sector is constrained by a number of institutional and technical factors, and farmers largely depend upon traditional sources of seed. The traditional sources meet more than two-thirds of the total seed demand , and the rest is met by the formal seed system, mainly public seed agencies. Most of the farmers buy fresh seed for quality reasons, and only 12-15 percent farmers purchase seed to change variety. In potato, technological innovation provided options to enhance... |

Lowland development efforts in West Africa have a mixed record. The paper posits that this is due to the neglect of: (1) market opportunity as driving force for lowland use; and (2) the wider context within which lowlands are used as important modifier. The paper applies a regression-based decomposition framework to analyze the factors driving and modifying lowland use in West Africa. It uses community-level data from 1014 geo-referenced lowland units around four urban centers along an agro-ecological gradient in Cote d'Ivoire and Mali. Tobit models are used to explain the extent of lowland non-use (seasonal fallow), its diversity (in terms of rice and other crop cultivation) and its land use intensity (double cropping). Results highlight that proximity to... |

Micronutrient malnutrition affects billions of people world-wide, causing serious health problems. Different micronutrient interventions are currently being used, but their overall coverage is relatively limited. Biofortification that is, breeding staple food crops for higher micronutrient contents has been proposed as a new agriculture-based approach. Yet, as biofortified crops are still under development, relatively little is known about their economic impacts and wider ramifications. In this article, the main factors that will influence their future success are discussed, and a methodology for economic impact assessment is presented, combining agricultural, nutrition, and health aspects. Ex ante studies from India and other developing countries... |

A growth accounting and an econometric exercise are used to provide insights into the evolution of the Taiwanese economy over the period 1966-96. The approach links the GDP function of a multiple sector neoclassical growth model to growth accounting and, subsequently to the estimation of the parameters of this function. The growth accounting results show that the contribution of total factor productivity (TFP) to growth in GDP averaged about 32 percent over the period, and this contribution increased as the economy approached its long-run equilibrium during the decade of the 1980s, with evidence of some departure during 1991-96. Growth in TFP increased output growth in industry and services while growth in skilled labor benefited all sectors. Growth in... |

Information and communications technologies (ICTs) have spread rapidly over the past decade. There has been considerable interest in the effect of such technology on search costs, search behavior and welfare outcomes, particularly in developing countries. This paper investigates the impact of a new search technology, mobile phones, on traders’ search and marketing behavior in Niger. We construct a novel theoretical model of sequential search, in which traders engage in optimal search for the maximum sales price, net transport costs. The model predicts that the introduction of a new search technology, such as mobile telephones, will increase traders’ reservation sales prices and the number of markets over which they search. To test the predictions of the... |
