| The purpose of this paper is to provide a conceptual framework that can be used by agricultural leaders, administrators, policy makers, and seed program managers to (1) understand key factors affecting seed system development; and (2) compare organizational and institutional strategies for increasing seed system effectiveness. A literature review of recent studies on seed system development in Sub-Saharan Africa (SSA) was undertaken to achieve these objectives. The studies reviewed included published and unpublished reports, monographs, and case studies. |

| Several characteristics of biotech industry structure follow cyclical patterns. Mergers and acquisitions activity shows cyclical behavior, with peaks from 1988-92 and 1996-97 and a valley from 1993-95. The ratio of large-firm to small-firm field trials, and the Herfindahl-Hirshmann concentration index, move pro-cyclically with M&A activity. This paper develops a formal, dynamic, neo-Schumpeterian model of endogenous R&D and innovation. The model generalizes and extends the literature on biotech industry concentration. For specified parameter values, the out-of-steady-state dynamics are examined, and shown to generate model behavior which is consistent with empirical descriptions of biotech concentration and R&D-activity cycles. |

| This report presents a summary of the results of an ex-ante socioeconomic assessment of the potential impacts of the improved cucurbits germplasm in Indonesia and South Africa. The cucurbits technology was developed by Cornell University through support from the USAID-funded Agricultural Biotechnology Support Project (ABSP). The objectives of these assessments were to: a) investigate the current status of the cucurbits subsector in Indonesia and South Africa; b) evaluate and quantify potential/projected benefits and costs of the cucurbits technology to seed companies, producers, and consumers in Indonesia and South Africa; and c) identify key issues that ABSP researchers, the ABSP management team, and USAID need to take into account in the development and... |

| The emergence of agricultural biotechnology and policy responses to is altering global agricultural trade patterns. This paper models the effects of restrictive policies concerning the production and consumption of genetically modified agricultural products. The model relies on a Hecksher-Ohlin-Samuelson framework, adapted to include neo-Schumpeterian research and innovation. The model includes two 'North' countries, the United States (US) and the European Union (EU), and the 'South'. The EU is represented as prohibiting the production and consumption of biotech products, but not restricting biotech research relative to NA. Model results include implications for economic growth, welfare, and trade patterns for the EU, US and S, given the restrictive... |

| In 1993, the Sasakawa/Global 2000 Program (SG) and the Ministry of Agriculture (MOA) began a joint program to demonstrate that substantial productivity increases could be achieved when farmers were given appropriate extension messages and agricultural inputs were delivered on time at reasonable prices. The program provided credit, inputs and extension assistance to participants willing to establish half-hectare demonstration plots on their own land. In 1995, the MOA/SG demonstration program reached more than 3,500 farmers. During the same year MOA launched the New Extension Program (NEP) based on SG principles but managed independently. By 1997, NEP was managing the bulk of the demonstration plots. Although the MOA/SG program is widely considered to be a... |
