The objective of the current paper is to explore the factors influencing the expansion and intensification of rice production in rainfed lowland sites. The village/lowland‐level data show the following: (1) the expansion of lowland rice cultivation has been driven by population pressure and accessibility to the market; and (2) the adoption of water control technologies is enhanced by the existence of immigrants and accessibility to the market. Rice cultivator data show that investment in water supply canals is influenced by land tenure security and that the canals enhance yield. This suggests that investment in water control technologies in rainfed lowland is necessary to realize a rice Green Revolution. Considering the fairly high average yield already achieved with water control technologies and the vast area of lowlands without water control technologies in rural area, there is a high potential of a rice Green Revolution in rainfed lowland in West Africa. 相似文献

This article advances the case for the more systematic incorporation of ideational factors into comparative capitalisms analysis as a corrective to the rational choice proclivities of the Varieties of Capitalism approach. It demonstrates the pay-off of such an ideationally attuned approach through analysis of French capitalist restructuring over the last 25 years, placing it in comparative context. A modus operandi for such ideational explanation is elaborated through delineating different national conceptions of the market, and setting out their impacts on practices of market-making. The claim made in this article is that understanding the evolution of French capitalism requires recognition of the ongoing market-making role of the French State, in combination with the French conception of the market and its embedding within a social context characterised by the inter-penetration of public and private elitist networks of France's ‘financial network economy’ which remains substantially intact. The ideational dimension is crucial because French understandings of the market and competition, the ideational building blocks of market-making, inform French state interventions and leave footprints on French institutions and market structures, and the evolutionary trajectory of French capitalism. In charting this trajectory, this article deploys the concept of post-dirigisme. We map out the parameters and causes of the post-dirigiste condition in France through examination of French bond market development, privatisation, the shift from a government- to a market- dominated financial system, and French capitalism's internationalisation. It then uses post-dirigisme to explain French state responses to the financial crisis and the banking bailout, noting how state actors, in concert with the banking elites, actively facilitated dominant market positions of French international champions. 相似文献

By utilizing previously unexplored plant–product data on Korean manufacturing, and detailed import data for 1991–1998, this paper empirically investigates whether greater access to imported intermediate varieties enhanced plant total factor productivity and product‐switching behavior. First, consistent with previous empirical studies, we find that a plant that belonged to industries with higher imported intermediate variety growth experienced higher productivity growth. Second, our empirical results suggest that increased imported intermediate varieties stimulated the product‐switching behavior of domestic plants. Because product‐switching behavior (i.e. simultaneously adding and dropping products) could be understood as a part of the continual process of ‘creative destruction’ within plants, our results imply that imported intermediate variety growth may be one of the channels through which resource reallocation within plants can be promoted. 相似文献

A production approach based on the translog cost function is used to analyze import demand for wheat differentiated by class and country of origin in the Japanese wheat flour milling industry. Results indicate that US wheat faces strong competition in the Japanese wheat market, but its multiple classes and end‐use characteristics enable the US to preserve the largest market share in Japan. 相似文献

Self-sufficiency in wheat has been one of the major goals of Iranian agricultural policies since the Revolution of 1979. Even so, the country failed to achieve this goal by the early 2000s, despite a satisfactory growth in wheat production. This paper addresses this failure and the political difficulties in introducing reforms that would reduce the need for import. First, the production and consumption of wheat are examined. The conclusion is that the cheap-bread policy has mainly been responsible for the imbalances between domestic supply and demand, and the continued reliance on wheat imports. Moreover, the paper argues that the subsidy program is an expensive safety net for the needy and shows that the Iranian government has intended to reform the program since the early 1990s. However, subsidy reforms are politically sensitive, especially in developing countries where subsidies are considered very important, both for supporting the poor and for political stability. An analysis of the Iranian attempts at subsidy reform suggests that they have not yet succeeded, mainly due to such political considerations. 相似文献

Dry‐land legumes, well adapted to drought‐prone areas, have largely been neglected in the past despite the good opportunities they offer for income growth and food (and nutritional) security for the poor. This study evaluated the adoption and impact of two farmer and market‐preferred and disease‐resistant pigeonpea varieties that were developed and promoted in semi‐arid Tanzania. The new varieties were resistant to fusarium wilt, a fungal disease devastating the crop. However, farmers wanting to adopt new varieties did not adopt due to seed access constraints and under‐developed seed delivery systems. Adoption of new varieties is therefore analyzed using an augmented double hurdle model that allows estimating variety adoption conditional on seed access thresholds accounting for the additional information on sample separation. The study identifies the crucial role of seed access (local supply), extension, education, participatory decision making, capital, and household assets in determining adoption. The social economic benefits of the technology and policies for improved seed access were further analyzed using the extended economic surplus method (DREAM model). Even under restrictive assumptions, overall discounted benefits were found to be quite attractive, indicating the need for additional efforts to scale‐up the success story. Analysis of changes in research benefits from relaxing the seed access constraint showed that net gains would increase by up to 30% if farmer access to improved seeds can be assured. Smallholder farmers are the major beneficiaries along with consumers and rural net‐buyers who gain from productivity‐induced lower market prices. 相似文献

The recent testing approaches of the ‘Law of One Price’ which ate based on co-integration analysis are modified by incorporating the seasonal components of the agricultural price series into the testing procedure. Application of the modified testing approach to the soft wheat market of live European Union member stales produces mixed results as some of the markets turn out to be integrated while in some cases a unified market cannot be assumed. I hese results differ in some cases from those obtained by co-integration tests which ignore seasonal unit roots. 相似文献
