| The paper presents a model developed to examine the effects of industry concentration on market power and cost efficiency in the seed industry. In addition, the paper presents preliminary measures of the relative strengths of these effects for the case of the U.S. corn seed industry over the past 3 decades. The model uses conjectural elasticities and is estimated using data collected from USDA sources. The empirical results allow us to distinguish between the market power and cost effects of concentration, and to ascertain the tradeoff between the cost efficiency and market power resulting from higher concentration in the corn seed industry. |

| The paper develops a framework for the design and analysis of pluralistic agricultural advisory services and reviews research methods from different disciplines that can be used when applying the framework. Agricultural advisory services are defined in the paper as the entire set of organizations that support and facilitate people engaged in agricultural production to solve problems and to obtain information, skills and technologies to improve their livelihoods and well-being… To classify pluralistic agricultural advisory services, the paper distinguishes between organizations from the public, the private and the third sector that can be involved in (a) providing and (b) financing of agricultural advisory services. The framework for analyzing pluralistic... |

| Despite more than a decade of policies placing high priority on cereal intensification, backed by one of the highest rates of public expenditures on agricultural in Africa, Ethiopia has yet to see payoffs in terms of higher and more stable cereal yields, reduced dependency on food aid, improved food security, and lower consumer prices for staples. There is understandable concern about the performance, efficiency and sustainability of the agricultural sector, specifically in terms of the current systems for providing extension services, improved seed, fertilizer, and credit. This paper aims to illuminate possible solutions available to improving the prospects for cereal intensification in Ethiopia. The paper traces the largely state-led policies that have... |

| This study, which examines the role of public–private partnerships in international agricultural research, is intended to provide policymakers, research managers, and business decision-makers with an understanding of how such partnerships operate and how they potentially contribute to food security and poverty reduction in developing countries. The study examines public–private partnerships in light of persistent market failure, institutional constraints, and systemic weaknesses, which impede the exchange of potentially pro-poor knowledge and technology. The study focuses on three key issues: whether public–private partnerships contribute to reducing the cost of research, whether they add value to research by facilitating innovation, and whether they... |

| This paper examines the role of postsecondary agricultural education and training (AET) in Sub-Saharan Africa in the context of the region’s agricultural innovation systems. Specifically, the paper looks at how AET in Sub-Saharan Africa can contribute to agricultural development by strengthening innovative capabilities, or the ability to introduce new products and processes that are socially or economically relevant to smallholder farmers and other agents in the agricultural sector. Using AET in Ethiopia and Mozambique as case studies, the paper argues that while AET is conventionally viewed in terms of its role in building human and scientific capital, it also has a vital role to play in building the capacity of organizations and individuals to transmit... |
