The establishment of intellectual property rights (IPRs) for plant varieties has caused considerable controversy, but there is relatively little empirical evidence on performance and options in developing countries. This paper summarizes the results of a recent five-country study, concentrating on the conduct of plant variety protection (PVP) regimes. It examines PVP in the context of other mechanisms that provide incentives for plant breeding. It discusses the principal options available to developing countries and examines the ability of PVP to offer protection from competing firms and from on-farm seed saving. It also looks at the administrative and management requirements of PVP regimes. Although the paper does not discuss patent protection for biotechnology it examines the IPR requirements for the introduction of transgenic varieties. Developing countries need to establish an appropriate PVP system, but PVP should be seen as part of a broader strategy for seed system development. 相似文献

This article presents an overview of the general changes in the food situation in developing countries over the past two decades, and especially since the 1974 World Food Conference. Following an examination of trends in production, consumption and trade in basic food staples of Third World countries, the article looks at possible strategies for improving their food situation. 相似文献

The analysis of value chains has augmented our knowledge on the complexities, inter-linkages, distributional benefits, and institutional arrangements of production and marketing channels in developing countries. However, the analysis remains relatively qualitative and case-specific, with limited ability to rank or assess the impact of alternative interventions or to analyze sufficiently the complex market dynamics and feedbacks present in livestock systems. This paper offers theoretical and applied insights on ways to improve the analytical rigor of the value chain methodology that combines both qualitative and quantitative approaches. 相似文献

Many studies have been made on the diffusion and development of broadband, however there are few published studies on the critical factors for advancing broadband services in developing countries. Thus, the purpose of this paper is to understand and identify the critical success factors for the development of broadband services in a developing country context, using the case of Peru. In this regard, this study uses data collected from interviews with Peruvian telecommunications professionals, policy makers and regional telecommunication experts, which is supplemented by official reports and statistical data to determine the critical success factors for broadband in this country. The four factors derived are; (i) expand the availability of infrastructure, (ii) define a national broadband policy that aligns the interests of stakeholders, (iii) develop effective competition in the broadband market, and (iv) stimulate the demand for broadband services. Through a MACTOR analysis the authors found that the objectives of sharing infrastructure, the further deployment of infrastructure and the development of competition in the market for broadband services are those that generate the most divergence between actors. Additionally, the MACTOR analysis determined that no disagreement existed for the objectives related to demand stimulation. Thus, four proposals are offered for the development of Peruvian broadband. The results are relevant for academics and policy makers interested broadband development in developing countries and for rural areas of developed countries. 相似文献

This paper assesses the growth impact of telecommunications infrastructure investment in developing countries by subjecting country-specific data on mainline tele-density and per capita growth to a Granger causality test within a panel cointegration framework. The results suggest that growth effects vary widely across country groupings reflecting different levels of development. Mainline tele-density and per capita growth strongly reinforce each other for countries that are relatively less developed. The reinforcement effect is even stronger for emerging countries that can be identified by their higher than average growth rates. In contrast, there is, at best, weak evidence of bi-directional causal links between the two variables for countries that are relatively more developed. These differences in the mainline tele-density and per capita growth relationships suggest that investment in telecommunications infrastructure, with its potential to generate high growth return, may serve as the critical tool for driving the growth and development process forward in the less developed countries. 相似文献

In many developing countries, the potential benefits from adopting a transgenic variety developed by a multinational corporation are limited by the crop’s small production base. This paper presents an ex-ante evaluation of the economic impact of herbicide resistant transgenic rice in a small developing country, Uruguay. To fully account for the multinational’s market power, the firm’s seed markup is assumed to affect the adoption rate for the variety. Stochastic simulation techniques are employed to understand how potential benefits may vary with changes in technology, yield, costs, and adoption parameters. The results indicate a $1.82 million mean net present value for producers from the development and utilization of transgenic rice in Uruguay and $0.55 million for the multinational. These relatively small multinational firm benefits suggest that a firm will not undertake significant efforts to develop transgenic varieties adapted to local conditions without either strategic partnerships with local institutions or access to wider regional markets. 相似文献
