水权交易是提高水资源配置效率和利用效率的有效途径,是我国未来水资源管理制度的改革方向。由于水资源的特殊属性,在水权交易中会不可避免地带来外部性问题。外部性问题的存在是导致市场失灵和资源配置低效率的根源之一。文章在分析水权交易的外部不经济的基础上,指出单纯依靠市场机制无法引导以效益最大化为目的的交易双方消除外部性,要消除水权交易带来的外部性问题,需要权威机构的进入。基于此,从水资源持续利用的角度出发,提出在一定的约束条件之下相应的制度建议——外部性问题的防范措施和对第三方的补偿措施。 相似文献

水权交易管理比较研究 总被引:1,自引:0,他引:1
水权交易是解决水资源短缺问题,进行水资源优化配置的重要手段之一,我国的水权交易尚在探索阶段。文章通过对中外水权交易的比较研究,得出水权交易的关键问题为初始水权配置、水权交易制度和水权交易价格。由此提出了我国发展水权交易的建议:建立与完善相应的水权交易制度;加强流域统一管理,进行水权初始分配;引入水权期权交易方式。 相似文献

水权交易是我国利用市场机制促进环保节水的方向,陕西省水权交易的基础性工作也已经展开.虽然陕北、关中和陕南都有水权交易的需求,但三地交易的目的不同,交易方式和制度机制设计也应当有所不同.陕北以跨流域水权转换来解决水资源不足的问题,关中以跨行业的水权交易来提高灌区的用水效率,陕南以跨区域的水权交易来建立市场化的生态补偿机制,提供生态保护的长久动力. 相似文献

不同水权制度下农户用水行为的比较研究 总被引:9,自引:0,他引:9
解决农用水资源配置效率低下问题 ,可采用提高水价、水权限制和可交易水权三种水权制度。通过提高农用水资源的价格 ,可以加大农户的节水投入 ,提高农用水配置效率 ,其代价是减少农户的农业经营利润 ,增加农民负担。采用不可交易的水权限制制度 ,只要水权配置适当 ,同样会提高农用水的利用率。在此基础上 ,实行可交易水权制度 ,通过向非农产业的水权转移 ,可以增加农户的经营利润 ,提高农户节水的积极性。通过水权交易 ,可以提高水资源的利用率 ,促进整个社会福利的增加 相似文献

跨国并购不仅局限于目标方和并购方双方的博弈,并购顾问是交易中重要的第三方,然而现有研究对跨国并购中专业顾问团队的关注较少。以中国企业发起的跨国并购为分析对象,研究并购方顾问团队对跨国并购交易时长的影响,具有重要的意义。研究表明,并购方顾问团队规模越大,并购交易持续时间越长,且经过工具变量等一系列稳健性检验后结论依然成立。此外,当顾问团队东道国经验越丰富或目标方为上市企业时,上述效应减弱。当交易为循序并购或并购方高管团队海外背景丰富时,上述效应增强。以上研究结论补充了并购顾问作用的相关文献,丰富了现有文献对并购交易完成前过程的认识,同时表明跨国企业应当根据交易特征选取匹配的并购顾问团队以提高并购效率,为企业跨国并购实践提供了重要的理论参考。 相似文献

第三方认证制度及其作用机制研究 总被引:2,自引:0,他引:2
作为一种降低交易费用的制度安排,第三方认证制度在现代经济活动中发挥了越来越重要的作用。第三方认证制度的出现,主要原因在于交易双方的信息不对称。该制度安排的机理在于,第三方认证机构为交易者提供了有效而可靠的信号,这既可有效地降低购买者的信息成本,又有利于卖方或生产者更好地与竞争者区别开来,争取更多的消费者。为了保证认证信号的真实性和可信性,政府对第三方认证机构进行必要的监管是必要的。 相似文献

Irrigation water rights and their governance structures constitute the foundation of local water institutions and profoundly influence water resource allocations, irrigated agricultural productivity and other consumptive water uses in the arid climate zones. This article explores the regional structures of irrigation water rights and water governance and empirically analyses the priority effects of water rights on irrigated agriculture at the micro level in Idaho, an arid and semiarid state in the western United States. We integrate a unique data set of water rights and water supplies with agricultural features and environmental characteristics into our empirical analysis. Results indicate that seniority in water resources allocation has significant, positive effects on both the average crop revenue and crop water use efficiency. Local water rights structures differ significantly in seniority and water sources from region to region. In response to the heterogeneity in local water rights structures, the aforementioned effect of allocative priority of water rights on average crop revenue per hectare and crop water productivity varies significantly, reaching up to an 87% difference, when measured across regions. In addition, the priority effects of water rights are nonlinear, which reflects the influence of historical patterns of water rights establishment on water institutions to date. 相似文献

Decentralization in Indonesia has resulted in an increased influence of local communities over the terms of logging agreements with timber companies. The outcomes of such community–company negotiations vary significantly across communities. What are the conditions that cause this variation, and how can the outcomes be more effectively and efficiently influenced by third-party actors such as the local government or NGOs? This paper addresses these questions by developing a game-theoretic model to illustrate the strategic interactions between communities and companies. The model allows for endogeneity of de facto property rights and bargaining positions. We show that third-party actions to improve the community’s bargaining position by raising its reservation utility may result in an increase in the area logged and thereby harm the environment. Our results indicate that the strategy of intervention matters. In particular, strategies that raise the sensitivity of interventions to local logging threats are likely to be more cost-effective in supporting communities and reducing forest degradation than more indiscriminatory strategies. The model will be relevant to other situations where communities negotiate contracts over natural resource use with outside actors in a context of weak property rights, a situation increasingly observed in other developing countries. 相似文献

Although the third-party payment system is a matter of heated debate among academics and policymakers, and empirical studies of it are commonplace, this paper is believed to be the first to theoretically model its macroeconomic impact on a small open economy. The outcomes indicate that increases in the use of third-party payments will have a positive effect on national income in such an economy, but an ambiguous effect on domestic interest rates if the Marshall-Lerner condition holds. However, if the Marshall-Lerner condition does not hold, then increases in third-party payments could lead to higher domestic interest rates in an economy of this type. Additionally, third-party payments will ambiguous effects on such an economy's foreign-exchange rate. 相似文献

This article measures irrigated agricultural outcomes under the prior appropriation doctrine by developing a model of farmers’ land allocations in response to water supply change. The modelling approach considers the institutional factors of water rights and permits the inclusive determination of water and land allocations. We utilize farm-level data of irrigated agriculture in Water District #1 in Idaho to examine the predictions from our theoretical model. The water rights priority date is consolidated at the farm level and used to differentiate farmers’ responses. We test a set of hypotheses that relate to water supply and crop revenue. Our results suggest that the water rights priority has a profound impact on agricultural outcomes, indicating strong institutional effects and weak influence of market-based approaches. Farmers respond to both long-term and seasonal water supply change and variation, and they respond to seasonal water supply forecasts in varied ways depending on their water rights portfolios, thus signalling a disproportionate distribution of potential impacts of water supply change. 相似文献

Entry restrictions are a common form of regulation in markets and occupations, either as a means of limiting the size of
a market or affecting the quality of products or services provided by it. This paper analyzes demand, cost and informational
characteristics that affect the impact of this type of policies on the quality mix of products provided by an industry and
the welfare of its consumers. Selective increases in the costs of entry such as licensing requirements and direct restrictions
with competitive bidding for entry rights are considered. We analyze the effects of these policies on entry decisions and
also the additional selection effects that are obtained when exit is allowed for and the rights to participate in an industry
can be freely traded. 相似文献
