Final Report-Workshop on Experiences and Options for Priority Setting in NARS, August 12-16, 1996, Nairobi, Kenya

The motivation for this workshop came from two sources. First, under a project funded by USAID (AFR/SD/PSGE/TDT Office), Michigan State University (MSU) has been carrying out various activities to assist African national agricultural research systems (NARS) and regional organizations to improve their capacity for strategic agricultural research planning, including technology assessment and priority setting within a commodity sector framework. Second, recent collaborative work by the International Service for National Agricultural Research (ISNAR) and the Kenya Agricultural Research Institute (KARI) has focused on the development of a process and methods for program-level priority setting. The objectives of the workshop were (1) to provide a forum for ASARECA member NARS to synthesize their experiences with institute and program-level priority setting and technology assessment; (2) to examine the process and methods developed by KARI/ISNAR and other NARS in commodity program planning; and (3) to develop country-specific frameworks and action plans for a priority-setting/technology assessment study in a focus program area, to be carried out beginning in late 1996.food security, food policy, Research and Development/Tech Change/Emerging Technologies, Downloads July 2008 - June 2009: 11, F0,

Efficient Mortgage Default Option Exercise: Evidence from Loss Severity

This paper extends options-based mortgage default theory to include transaction costs. When transaction costs are considered, the rational borrower will default only when the value of the collateral falls below the mortage value by an amount equal to the net transaction costs. Since, for most borrowers, net transaction costs are positive, standard measures of equity may be significantly negative by the time the rational borrower exercises the default option. This research shows theoretically and empirically the effects of frictions on the individual strike price. The addition of transaction costs to the theory provides several testable implications for equity loss severity. First, the longer the foreclosure process and the period of free rent to the borrower, the lower the severity. Second, severity will be smaller when bankruptcy has been declared. Third, severity is decreasing in the contract decreasing function of the probability of a deficiency judgment. The empirical results, using servicing and foreclosure data from a large northeastern thrift, support the theoretical model.

EVALUATING MEASURES TO IMPROVE AGRICULTURAL INPUT USE

This paper provides guidelines to assist policymakers and analysts in (1) identifying promising public and private actions for promoting agricultural intensification by improving the availability and profitability of agricultural inputs; and (2) evaluating the relative costs and benefits of alternative actions. The guidelines are illustrated by reference to a study of phosphate fertilizer promotion in Mali originally conducted by IFDC researchers.Farm Management,

The Impact of Agricultural Technology in Sub-Saharan Africa: A Synthesis of Symposium Findings

The Symposium on the Impact of Technology on Agricultural Transformation in Sub-Saharan Africa funded by AID/AFR/ARTS and AID/RD/EID under the Michigan State University Food Security Cooperative Agreements, was held in Washington, D.C., Oct. 14-16, 1992. A primary purpose of the symposium was to present evidence which would either confirm or contradict the perception that the accomplishments of TDT were insufficient to justify continued funding. A secondary objective was to consider the adequacy of available analytical tools for impact assessment. The rate of return (ROR) is the most commonly used valuative measure of investments in technology development and transfer. Examined as a group, the estimated RORs support the proposition that African agricultural research has had people-level impacts, and that these impacts are large enough to justify the level of investment that led to the impacts. An important part of the impact assessment story is the analysis of factors that had a positive or negative effect on the impact of TDT. Five major factors emerged from the studies presented and comments by symposium participants: agroclimatic conditions, civil unrest, research system performance, policy, and markets. Progress has been made in moving forward with the process of TDT, in spite of adverse conditions. This progress includes enhancing the capabilities of national, regional and international institutions to generate new techniques, pushing forward the technology frontier, transferring technology, and increasing productivity both in farm production and post-harvest activities. Activities such as structural adjustment, improvements in agricultural and macroeconomic policy, greater reliance on democracy and capitalism, investments in infrastructure, and a greater willingness to work with the private sector have increased the potential for TDT to have significant impact. Given the importance of raising productivity in agriculture as a step towards agricultural transformation, continued investment in agricultural TDT is merited. The evidence of impact achieved from previous investments shows that those investments have paid off. Coupled with the evidence of beneficial changes in the macroeconomic policy environment in many countries, this provides the basis for expecting that future investments will pay off. What is perhaps unique about the symposium is the movement towards a commodity sector perspective as the next logical step toward including more demand-side considerations in the TDT agenda.International Development, Research and Development/Tech Change/Emerging Technologies, Downloads July 2008 - June 2009: 18,

COMPARING THE PROFITABILITY OF CASSAVA-BASED PRODUCTION SYSTEMS IN THREE WEST AFRICAN COUNTRIES: COTE D'IVOIRE, GHANA AND NIGERIA

Sub-Saharan Africa (SSA) cassava-producing countries such as Nigeria, Ghana, and Côte d'Ivoire have developed, in recent years, a renewed interest in cassava as an alternative food crop. This has led to a major expansion in cassava-based production systems in Nigeria and Ghana, whereas there has been a slower growth in Côte d'Ivoire (Nweke et al., 1998). This paper is based on the argument that the difference in various factors such as agricultural policies (i.e., trade and price policies, domestic production taxes or subsidies), location and technologies (production and processing) between Nigeria, Ghana and Côte d'Ivoire the difference in the level of growth in cassava-based production systems. The paper examines, using the Policy Analysis Matrix (PAM), the magnitude of the impact of these factors on the private and social profitability of cassava production and post-production processing in Côte d'Ivoire, Ghana and Nigeria. The topic has not been examined in previous studies. The paper relies primarily on data for Côte d'Ivoire, Ghana and Nigeria from the Collaborative Study of Cassava in Africa (COSCA) survey. The baseline results demonstrate the similarity in efficiencies of production in these West African countries. The simulation findings indicated that, in Côte d'Ivoire, farmers benefited from the depreciation of the equilibrium exchange rate while farmers in Ghana and Nigeria suffered losses. Simulation results also indicated that Ivorian and Ghanaian cassava/maize farmers could benefit from growing IITA's improved variety and adopting mechanized processing methods.Crop Production/Industries,

GETTING TECHNOLOGY AND THE TECHNOLOGY ENVIRONMENT RIGHT: LESSONS FROM MAIZE DEVELOPMENT IN SOUTHERN AFRICA

This paper examines two questions: (1) what were the most important factors that led to differential rates of adoption of maize technology by farmers in Zimbabwe, Zambia, and Malawi from 1910 to 1995? and (2) what do these experiences suggest about strategic investments in institutions and organizations needed to create a sustainable environment for technology development and adoption in the future? The analysis suggests that productivity increases are facilitated by (a) technology innovations throughout the agricultural system, (b) integration of technological innovations with changes in policies, organizations, human capital and infrastructure related to extension, input and output markets and processing services, and (c) coordination of these innovations across different stages of the agricultural system.Crop Production/Industries, Research and Development/Tech Change/Emerging Technologies,

FINANCIAL AND RISK ANALYSIS OF MAIZE TECHNOLOGY IN ETHIOPIA, BASED ON CERES-MAIZE MODEL RESULTS

This paper presents a financial and risk analysis of improved versus traditional maize production technology in Ethiopia, based on yields simulated with the CERES-Maize crop growth model (Schulthess and Ward, 2000). The purpose is to analyze the potential performance of the SG2000/Ministry of Agriculture program technology under less favorable meteorological conditions (rainfall level and distribution), and in areas with lower agroecological potential than those covered by the SG2000/MOA program through 1998. At the time of this study, expansion of the MOA program into lower potential zones seemed likely. Results show that use of fertilizer and improved seed is highly profitable under a variety of assumptions about crop growth conditions, maize prices, and fertilizer costs. Risk is examined using simple sensitivity and breakeven analysis, and stochastic dominance analysis.Crop Production/Industries, Research and Development/Tech Change/Emerging Technologies,
