CONCENTRATION, MARKET POWER, AND COST EFFICIENCY IN THE CORN SEED INDUSTRY AgEcon
Fernandez-Cornejo, Jorge; Spielman, David J..
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.

Innovation Systems and Technical Efficiency in Developing-Country Agriculture AgEcon
Mekonnen, Dawit Kelemework; Spielman, David J.; Fonsah, Esendugue Greg.
The paper uses a stochastic frontier analysis of production functions to estimate the level of technical efficiency in agriculture for a panel of 29 developing countries in Africa and Asia between 1994 and 2000. In addition, the paper examines how different components of an agricultural innovation system interact to determine the estimated technical inefficiencies. Results show that the mean level of technical efficiency among the sampled countries was about 86 percent, with some modest increases during the period in question. These results suggest that there is room for significant increases of production through reallocations of existing resources. Despite significant variation among countries, these results also indicate quite a number of least...

Organic Rural Innovation Systems and Networks: Findings From a Study of Ethiopian Smallholders AgEcon
Spielman, David J.; Davis, Kristin E.; Negash, Martha; Gezahegn, Ayele.
Agriculture in Ethiopia is changing. New players, relationships, and policies are influencing the ways in which information and knowledge are used by smallholders. While this growing complexity suggests opportunities for Ethiopian smallholders, too little is known about how these opportunities can be effectively leveraged to promote pro-poor processes of rural innovation. This paper examines Ethiopia’s smallholder agricultural sector from an innovation systems perspective to understand the changing roles, responsibilities, and interactions of diverse actors in relation to smallholder livelihoods. The paper uses a combination of qualitative and quantitative research tools to paint a picture of the innovation landscape at both the system and local levels....

Policies to Promote Cereal Intensification in Ethiopia: A Review of Evidence and Experience AgEcon
Byerlee, Derek R.; Spielman, David J.; Alemu, Dawit; Gautam, Madhur.
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...

PUBLIC-PRIVATE PARTNERSHIPS IN AGRICULTURAL RESEARCH: AN ANALYSIS OF CHALLENGES FACING INDUSTRY AND THE CONSULTATIVE GROUP ON INTERNATIONAL AGRICULTURAL RESEARCH AgEcon
Spielman, David J.; von Grebmer, Klaus.
Public-private partnerships offer potentially important opportunities for pro-poor agricultural research in developing countries. Yet in the international agricultural research community--and with regard to the Consultative Group on International Agricultural Research (CGIAR) itself--we see few examples of successful public-private partnerships, and fewer examples where such collaborations have contributed to food security, poverty reduction and economic growth. This study assesses the opportunities for, and challenges to, creating and sustaining public-private partnerships between the international agricultural research centers of the CGIAR and leading multinational, research-based agribusiness companies. The study hypothesizes that the willingness and...

Rural Innovation Systems and Networks: Findings from a Study of Ethiopian Smallholders AgEcon
Spielman, David J.; Davis, Kristin E.; Negash, Martha; Ayele, Gezahegn.
Agriculture in Ethiopia is changing. New players, relationships, and policies are influencing how smallholders access and use information and knowledge. Although this growing complexity suggests opportunities for Ethiopian smallholders, too little is known about how these opportunities can be effectively leveraged to promote pro-poor processes of rural innovation. This paper examines Ethiopia’s smallholder agricultural sector to provide qualitative insights into the interactions between smallholders and other actors in the agricultural sector and the contribution those interactions make to the smallholders’ innovation processes. Case studies of smallholder innovation networks in 10 communities suggest that public sector extension and administration exert a...

Sharing Science, Building Bridges, and Enhancing Impact: Public–Private Partnerships in the CGIAR AgEcon
Spielman, David J.; Hartwich, Frank; von Grebmer, Klaus.
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...

Strengthening Agricultural Education and Training in Sub-Saharan Africa from an Innovation Systems Perspective: Case Studies of Ethiopia and Mozambique AgEcon
Davis, Kristin E.; Ekboir, Javier M.; Mekasha, Wendmsyamregne; Ochieng, Cosmas M.O.; Spielman, David J.; Zerfu, Elias.
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...

The Private Sector in Agricultural R&D: Policies and Institutions to Foster its Growth in Developing Countries AgEcon
Naseem, Anwar; Omamo, Steven Were; Spielman, David J..
New technologies are critical to enhancing agricultural productivity and reducing poverty in many developing countries. While public-sector investment in research has historically driven technological change in agriculture, recent trends suggest that the public sector’s role may not be as significant in the future. There is much optimism about the private sector’s capacity to deliver new technologies, even though current levels of private investment in research in developing countries remain low. This paper examines the determinants of private investment in agricultural research and development in developing countries, the market and institutional constraints that limit private investment growth, and the incentive mechanisms that can strengthen private...
