Sedimentation of reservoirs in India

The sedimentation of Indian reservoirs has become a serious problem due to the synergistic action of population growth, intensity of agricultural operations, poor soil conservation and deforestation. This article examines the reasons for and responses to, sedimentation in three Indian reservoirs — Nizamsagar, Tungabhadra and Sriramsagar. The land management practices adopted in each case are analysed with reference to current and future needs. The article highlights particularly the need to monitor methodically the land use changes in the catchments of reservoirs.

工业用地空间错配对长三角城市群产业分工的影响研究

研究目的：考察工业用地空间错配对长三角城市群产业分工的影响效应及作用机制，为从土地资源配置视角深化产业分工提供科学依据。研究方法：动态面板模型、中介效应模型。研究结果：（1）样本考察期内，长三角地区工业用地空间错配有所改善，中心城市总体呈短缺型错配，外围城市总体呈过剩型错配。（2）工业用地空间错配对产业分工具有显著且稳健的负面影响。（3）区域异质性分析表明，工业用地空间错配对产业分工的负面影响呈现中心城市＞外围城市＞城市群总体；时间异质性分析表明，随着2016年长三角地区土地约束加码，工业用地空间错配对产业分工的负面影响增强。（4）影响机制分析表明，工业用地空间错配促进了产业由中心城市向外围城市转移，但中心城市高端制造业流失和外围城市承接产业同质化，抑制了产业分工深化。研究结论：稳步推进工业用地空间错配的纠偏和制定科学的产业转移规划，是深化城市群产业分工、推进城市群高质量发展的有效途径。     

论矿业权无形资产评估的可行性

论证矿业权制度的设立、矿业权流转及矿业权价值评估的必要性，这仅仅是问题的一方面。另一方面还应揭示出矿业权价值来源于何处，需找到价值补偿的源泉。本文论述矿山地租的形成、表现形式，它与超客利润的联系以及矿产资源开采收益、矿业权使用费和矿业权价值上的具体体现。     

欠发达地区农村土地流转的成效、困境及出路——以广东省廉江市为例

土地流转制度,作为当前支撑我国农村经济、发展现代农业和提高农民收入的重要途径之一,已经得到广大人民群众的普遍共识。但是,在现实条件下,在实践过程中,特别是一些欠发达地区,通过推动农村土地流转,其功效到底如何,又会发现什么样的新问题、新瓶颈,需要从政策上、制度上、经济上给予怎样的扶持?这些都要立足调查研究。为此,笔者以广东省廉江市作为调查对象,对其农村土地流转的成效、现实困境进行分析总结,并提出对策建议,完善土地流转制度,从而最终为有效解决"三农"问题提供帮助。

企业并购估值中的威斯通模型扩展研究

威斯通模型是企业并购估值贴现现金流模型中具有代表性的研究。在威斯通固定增长模型的基础上,建立了考虑未来经营失败概率的估值模型;对威斯通超常增长而后无增长模型进行了修正,探讨了企业在超常增长期采取不同投资策略对其价值的影响,建立了一个更为简明的估值模型,并给出隐含超常增长期限的一种计算方法。     

Stock Market Valuation, Profitability and R&D Spending of the Firm: The Effect of Technology Mergers and Acquisitions

Abstract:  In this paper, we investigate whether a firm can enhance the effect of its R&D spending on its current market value and future profitability through technology-oriented M&As. On the basis of an analysis of 1,879 M&As, we find that when a technology firm acquires another technology firm, the magnitude of the stock price response to the R&D spending of an acquirer increases by 107% in the year of the M&A. In contrast, we find no such increase in the stock price response to the R&D spending of a non-technology acquirer. We also find that technology acquirers are more successful in converting their R&D spending into positive future profitability than non-technology acquirers. Our results are robust for different alternative specifications of our model and when various firm differences are controlled for.     

‘Adopt a Hypothetical Pup’: A Count Data Approach to the Valuation of Wildlife

The willingness to pay (WTP) for a coyote conservation program is estimated using a novel payment-vehicle, based on how many ‚problem’ coyotes respondents would be willing to sponsor for a year. This hypothetical scenario mimics an increasingly popular type of actual market. Data from a phone survey conducted in Prince Edward Island are analyzed using count data models that consider different processes explaining zero responses and the level of positive responses. This is particularly important in the case of coyotes, often regarded as an economic bad. Estimates of WTP per coyote per year around $18–$22 and annual WTP per contributor of about $46–$57 are obtained.
