This paper uses primary data to analyze the institutions and informal markets that govern groundwater allocation in a sugarcane-cultivating village in North India. We find that, in contrast to earlier literature, the observed water trades result in efficient water allocation across farms. We interpret this and other stylized facts in terms of a social contract using a simple bargaining model with limited inter-player transfers. Poor functioning of the power sector leads to reduced pumping and a water supply constraint. Simulations show that power supply reform can significantly increase farm yields, and be financed out of increased farm profits. 相似文献

The present paper describes the benefits and costs, in qualitative terms, of managing food price instability in Asia in the context of promoting economic growth and poverty reduction to improve food security. The experience of Asian governments in actual practice with price stabilization is discussed in the context of managing an efficient transition to market‐mediated food security. Recent experience in Indonesia, where a sharp increase in rice prices (caused by a ban on rice imports) pushed 4 million people into poverty, provides continued motivation for the analytical story in this paper. 相似文献

Investment overseas for Chinese oil and gas enterprises can help them find more stable sources of oil, diversify oil import, and disperse oil supply security. It is an important means of oil security and also can enhance oil company's international competitiveness. Selection of the pattern plays an important role. So while making decision, investment pattern's features and influencing factors must be considered. 相似文献

China's small farmers face increasing challenges because of land and water resource constraints and the effects of climate change. With the strengthened agricultural stimulus policies, poverty reduction and social protection programs, as well as the expanding international food trade, up to now China has achieved food security through small farm agriculture. During intensive economic restructuring, smallholders still coexist with large‐sized farms and industrialized agricultural businesses, but are in a vulnerable position in market transactions. Oriented to 2050, China's agricultural development and food security policies should work to improve domestic market structure, to further release international trade control and to empower smallholders. 相似文献

企业多元化经营作为企业成长和发展的重要战略之一,既有成功实施的广泛代表性,又不乏失败的惨痛教训。为找出多元化经营与企业绩效之间关系,选取了57家沪深上市公司作为研究对象,利用其公布的2006年—2008年连续三年的年报,搜集、整理、计算了衡量企业多元化程度的赫芬达尔指数,并与一系列衡量企业经营绩效的指标如每股收益、净资产收益率及To-bin's Q值建立回归模型。通过统计分析,得出了多元化与企业绩效之间关系的研究成果,并提出实施多元化经营的政策建议。 相似文献

The paper jointly evaluates the determinants of switching to Jasmine rice and its productivity while allowing for production inefficiency at the level of individual producers. Model diagnostics reveal that serious selection bias exists, justifying use of a sample selection framework in stochastic frontier models. Results from the probit variety selection equation reveal that gross return (mainly powered by significantly higher Jasmine rice price), access to irrigation and education are the important determinants of choosing Jasmine rice. Results from the stochastic production frontier reveal that land, irrigation and fertilisers are the significant determinants of Jasmine rice productivity. Significantly lower productivity in Phitsanulok and Tung Gula Rong Hai provinces demonstrate the influence of biophysical and environmental factors on productivity performance. The mean level of technical efficiency is estimated at 0.63 suggesting that 59% [(100 ? 63)/63] of the productivity is lost due to technical inefficiency. Policy implications include measures to keep Jasmine rice price high, increase access to irrigation and fertiliser availability, as well as investment in education targeted to farm households which will synergistically increase adoption of Jasmine rice as well as farm productivity. 相似文献

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. 相似文献

Profitability of cow-calf production is determined largely by market prices, calf weaning weights, and cow productive life. While producers individually have no effect on prices, weaning weights and productive life have genetic influences and hence can be altered by selection programs implemented by producers. We investigate the impact of a mutation in the leptin gene (exon 2; single nucleotide polymorphism [SNP] 305) on cow-calf profitability. Prior research shows that this mutation has effects on performance and traits of fed cattle and milk production in dairy cows. Using data from a teaching-research herd, we find that it is also associated with calf weaning weights and cow productive life. A bio-economic stochastic simulation demonstrates that the mutation has statistically positive impacts on profits, suggesting that producers can profitably make use of this information. 相似文献

Global trade in agriculture and food products is increasingly governed by an array of standards. In order to continue exporting, developing countries have little choice but to comply with the new requirements. This study uses a census based panel data set from the nascent floriculture industry in Ethiopia to empirically examine the determinants of firms’ adoption of international private standards in fresh horticulture produce in large‐scale estate farms. The econometric analysis shows that larger size, older, and foreign owned firms are more likely to adopt the private standards. Moreover, this study analyzes the overall industry level efforts and public–private partnership to launch and implement a national scheme GAP and build a firm's capacity to comply with the standards. 相似文献

We explore trust development in the context of an international merger negotiation. Based on in‐depth interviews with chief negotiators of the Air France–KLM merger, we contribute to existing theory by showing that trust develops in three interrelated domains: personal, process, and outcome. Progressively, trust develops in all domains on the basis of antecedents that differ between phases and domains. Distinguishing between different domains facilitates analysis of trust asymmetry and the coexistence of trust and distrust, as well as the influence of trust in interorganizational relationships. 相似文献
