以实验区建设为契机提高服务"三农"的能力

该文通过总结分析贵州省实验区建设取得的成就,认为实验区建设对于提高资源利用率、促进农民增收、扩展农业资源区划工作的内涵和外延都有着积极的意义。当前实验区工作的重点是做好四个结合,在不突破现有政策框架的前提下大胆探索和实践,不断提高服务"三农"的能力。     

Myopia and saliency in renewable resource management

An important challenge in managing renewable resources is to understand why owners and managers sometimes make decisions that deplete resources and future earnings, such as when graziers allow pastures and land condition to be degraded. In this paper, we test two potential reasons for unsustainable management practices, myopia and salience, with each explaining why resource managers may exhibit impatience in harvest decisions. Myopia is associated with decision makers placing lower weight on future outcomes than would be implied by their pure time preference. Salience is associated with overweighting of consumption ‘now’, implying inconsistency in time preferences. To test for these effects on renewable resource management, an incentivised, dynamic field experiment was carried out with rangeland grazing enterprise owners in north‐eastern Australia that related management choices with uncertain rainfall events to both profits and land condition over time. Results demonstrate that respondents exhibiting myopia/salience in their choices tended to achieve lower cumulative scores in the experiment, as well as lower land conditions on their properties as measured with remote sensing data. Our results explain why there may be persistent optimisation failures by resource owners that reduce both profits and environmental outcomes.     

Warning labels on junk food: experimental evidence

Unhealthy food choice is one of the main causes of being overweight. Nutritionists blame a particular category of food: junk food. Several authors have proposed a fat tax for reducing the junk food demand, but others have demonstrated that these taxes must be very high in order to be effective. Therefore, a warning label about calorie content may be an alternative way to reduce the consumption of junk food. In this exploratory study, using students as respondents, a high‐calorie warning label is explored with an incentive compatible valuation method. The results indicate that a high‐calorie warning label has little effect on respondents’ choices, even when they have no prior familiarity with the food.     

论我国证据规则的现状及完善

证据制度是诉讼制度的核心 ,是实现司法公正的必要条件 ,决定着诉讼的最终结果 ,证据规则是证据制度的主要内容 ,但我国缺乏具体的、具有可操作性的证据规则 ,与证据在诉讼中的地位不相称 ,现有的证据规则也不能满足实践的需要 ,本文就我国现有的证据规则的现状和加强证据规则立法的必要性以及如何完善我国证据规则提出看法。
