Farmland for tomorrow in densely populated areas

The paper describes the results of a research that aimed to come up with a well structured method to estimate future farmland requirements in densely populated areas. By using in depth interviews, scenario analysis and strategic orientation rounds, a method is developed to support policy optimization and to explore alternative future developments. The method is applied to the case of agriculture in the Flemish part of Belgium to show the feasibility of the model and to provide input for the discussion among policy makers in Flanders. The research results can be used by policy makers to build a new Spatial Plan Flanders for the period 2007–2013.     

开发区失地农民补偿安置及生存状况研究 ——以泰安市高新技术产业开发区为例

研究目的：通过泰安高新技术产业开发区失地农民补偿安置案例,透视开发区失地农民生存状况,发现开发区失地农民补偿安置方面的问题,找出解决开发区失地农民问题的方向。研究方法：田野调查法、对比分析法。研究结果：（1）泰安开发区土地征收补偿标准符合国家法律规定;新房抵旧屋的房屋拆迁补偿方式深受农民欢迎。（2）土地征收使当地农民就业率小幅下降,但农民就业结构明显改善。（3）开发区失地农民当前的生存状况良好,但缺乏长期的生存保障机制。研究结论：防止失地农民生存状况恶化,解除失地农民后顾之忧的根本措施在于做好失地农民的就业安置和社会保障。     

国际投资协定透明度要求变化及其启示 ——以美国实践为考察对象

以美国BIT为代表的国际投资协定在透明度条款以及其他条款涉及透明度的规定中通过加强公众参与程度显著提升了透明度要求。这一变化是投资仲裁实践、国内贸易立法以及市民社会诉求合力作用的结果。透明度要求的提高一方面凸显了专业性社会组织对国际投资立法与实践的影响,另一方面则反映了美国借此维护本国利益的实质。对此,中国在对外投资协定的签署与实践中需要审慎对待透明度要求,同时加强本国专业性社会组织的培育和发展。

投资者会听话听音吗??--基于管理层语调视角的实证研究

我国投资者会听话听音吗？文章利用文本分析方法,基于我国上市公司2005－2012年年度业绩说明会上的管理层语调数据对此进行了实证检验。研究发现,投资者对管理层的净正面语调做出了显著的正向反应,尤其是对负面语调做出了显著的负向反应。这表明在我国强调“意会”的语境文化背景下,投资者会听话听音,管理层语调具有信息含量,上市公司的业绩说明会具有其自身的存在价值。文章的研究结果还意味着,“词袋”方法及其构建的管理层语调用词列表在我国儒家文化背景下具有一定的适用性,值得开展进一步的研究。     

Optimal surveillance against foot‐and‐mouth disease: the case of bulk milk testing in Australia

Previous foot‐and‐mouth disease (FMD) outbreaks and simulation‐based analyses suggest substantial payoffs from detecting an incursion early. However, no economic measures for early detection have been analysed in an optimising framework. We investigate the use of bulk milk testing (BMT) for active surveillance against an FMD incursion in Australia. We find that BMT can be justified, but only when the FMD entry probability is sufficiently high or the cost of BMT is low. However, BMT is well suited for post‐outbreak surveillance, to shorten the length of time and size of an epidemic and to facilitate an earlier return to market.     

Raising offtake from cattle grazed on natural rangelands in sub-Saharan Africa: a transaction cost economics approach

Farmers in sub‐Saharan Africa are constrained by large transaction costs associated with marketing of their livestock. However, transaction costs are often not taken into account in the analysis of factors hampering the development of livestock marketing in this region. This article empirically measures the influence of transaction costs on the offtake from cattle grazed on natural rangelands in Uganda. The study is based on the monitoring of 696 cattle transactions in three districts of Uganda from August 2004 to August 2005. The estimated models suggest that proportional transaction costs represented by the state of roads, distance to markets, and time taken to reach the market are important variables constraining market participation. In order to raise offtake from the national herd, it is essential to explicitly address these costs. One potential solution is collective action in marketing of livestock in which proportional and fixed transaction costs are reduced and shared among the group members.     

Non‐Parametric Modelling of CO2 Emission Quota

Dutch glasshouse firms are facing the introduction of a system of tradable CO₂ emission quotas. This paper employs a non‐parametric method for modelling tradable CO₂ emissions of Dutch glasshouse firms. The method is capable of generating shifts in CO₂ emissions across the sample of firms. Moreover, changes in volumes of outputs produced and inputs used are computed. Results show that firms using a conventional heating technology will be net purchasers of CO₂ emissions, whereas firms using more advanced heating technologies will sell part of their emission quota.
