Ex ante analysis of the benefits of transgenic drought tolerance research on cereal crops in low-income countries

This article develops a framework to examine the ex ante benefits of transgenic research on drought in eight low-income countries, including the benefits to producers and consumers from farm income stabilization and the potential magnitude of private sector profits from intellectual property rights (IPRs). The framework employs country-specific agroecological–drought risk zones and considers both yield increases and yield variance reductions when estimating producer and consumer benefits from research. Benefits from yield variance reductions are shown to be an important component of aggregate drought research benefits, representing 40% of total benefits across the eight countries. Further, estimated annual benefits of US$178 million to the private sector suggest that significant incentives exist for participation in transgenic drought tolerance research.

Distinguishing Economically from Legally Formal Firms: Targeting Business Support to Entrepreneurs in South Africa’s Townships*

Although the government of South Africa (SA) has formally adopted a policy of proactive support of entrepreneurship, providing business assistance to all of its entrepreneurs is beyond SA’s financial and human resource capabilities. This study utilizes the results of an in‐depth survey of entrepreneurs in SA’s townships to find: (1) The business and owner traits that predict revenues and job creation among the township entrepreneurs, (2) The key issues that challenge township entrepreneurs; and (3) What the answers to these issues imply about the appropriate content and recipients of business assistance to township entrepreneurs. A distinction is helpful in framing this study’s approach. In SA, registered (licensed) businesses are legally formal firms. In contrast, economically formal firms have institutionalized processes that lead to success as a profit‐making firm. We use this distinction in our analysis of the data and framing of the implications for business assistance strategy in SA.     

Personal selling and sales management: A relationship marketing perspective

The authors examine how the practice of personal selling and sales management is changing as a result of the increased attention on long-term, buyer-seller relationships and identify some implications of these changes. Changes in the traditional personal selling and sales management activities are needed to support the emergence of the part-nering role for salespeople. For salespeople in the part-nering role, the personal selling shifts from a focus on influencing buyer behavior to managing the conflict inherent in buyer-seller relationships. The emphasis on building relationships rather than making short-term sales and the use of sales teams dictates changes in the way firms select, train, evaluate, and compensate salespeople and members of sales teams. In this article, the authors have suggested some issues concerning the emerging partnering role for salespeople that deserve the attention of scholars interested in personal selling and sales management research.

Teaching Net Present Value Analysis: Returns-to-Assets versus Returns-to-Equity

We survey textbooks from agricultural economics and other subject matter areas to determine their treatments of the returns-to-assets versus returns-to-equity methods for determining the net present value of investment projects. Textbook authors disagree about the appropriate method, often give conflicting advice as to how a given method should be applied, and do not show how the results of the two methods can be reconciled. We provide a consolidated discussion of the circumstances under which the two methods produce the same net present value.     

Ex-ante agricultural research evaluation with site specific technology generation: the case of sorghum in Kenya

Agricultural commodity research has very site-specific productivity impacts. Crucial determinants of the magnitude and distribution of research benefits include agroecological conditions for technology generation and adoption, as well as commodity market-structure. This paper presents a process for ex-ante research evaluation which accounts for these factors with a dynamic, spatial multi-market model. Simulation results based on sorghum research in Kenya demonstrate that potential research benefits can vary dramatically research program research target zones. In Kenya, however, population-induced demand growth not technological development will have the greatest influence on future sorghum markets.     

Investigating differences among research projects and implications for managers

As research and innovation have become central to the economy, the challenge of managing these activities has taken on greater importance. Studies have focused on the impact of organizational variables on research activities, such as work environment, human resource factors, and managerial practices. But little attention has been paid to the effect of differences among types of research projects. While the notion that differences exist among research projects is acknowledged, particularly in the research & development portfolio literature, there have been relatively few studies into the dimensions by which research projects, and needs of project team members, differ. Further, there is little recognition that these differences translate into the need for different research project management practices. The objective of this paper is to investigate differences among research projects along three dimensions, amount of funding, complexity of project teams, and research orientation. These dimensions are selected because of their central theoretical importance in the organizational literature, as well as posing a number of different challenges for research management. This study looked at 18 research projects at a national laboratory and analyzed the responses of project members to a comprehensive research environment survey conducted in 2001. The results of the analysis indicate that there are significant differences between types of projects along three dimensions and suggest ways that research performance can be improved through management intervention.
