Are Social Costs the Outcome of Struggles over Truth?

Abstract:

This article critically examines the institutional economics theory of social costs by way of reviewing The Dark Places of Business Enterprise: Reinstating Social Costs in Institutional-Economics (2019). In particular, the article assesses the proposal to re-root institutional economics in the theoretical synthesis of “Veblen-Kapp-Mirowski” to better understand the social costs of neoliberalism. One of the findings is that while such a synthesis seems justified on the grounds of significant commonalities and the merits of deeper insights, it nevertheless runs into difficulties due to divergent philosophical foundations. One of the conclusions is that further philosophic clarification is needed on how an alternative economy would understand the relationship between “social costs” and Truth.

高速铁路动车组检修资源布局优化研究

高速铁路网的日趋完善,高速列车开行数量的进一步增加,对高速铁路动车组检修资源布局提出新的要求。为合理优化动车组检修资源布局,提高动车组检修效率,在分析我国动车段和动车运用所管理模式及布局方案的基础上,将动车组检修资源布局优化问题转化为基于多基地车辆路径运用的基地选址问题,基于"备选运用所-运输需求-动车组运用"间的关联关系构建动车组运用检修接续网络,建立动车组检修资源布局优化模型。以某区域的铁路网为例,利用近远期规划优化动车组检修资源布局,验证模型有效性,为今后动车组检修资源布局优化提供参考。     

Ramshackle farmhouses,useless old stables,or irreplaceable cultural heritage? Local inhabitants’ perspectives on future uses of the Walser built heritage

Social and economic developments in rural regions call for a discussion of strategies of dealing with redundant traditional buildings. Using a social science approach, our study examines how the local population in two rural regions perceives the built heritage and which factors are underlying these perceptions. People’s attitudes towards maintaining the cultural heritage vary considerably and are partly influenced by the socio-cultural and economic context of the region. The present article discusses some of the core regional socio-cultural influences on attitudes towards the rural built heritage. Following from qualitative interviews, the article concludes that the scale of perception of the built heritage is related to the “liveliness” of the local culture: The more original and distinctive the local culture is, and the more the local economy is still based on agriculture, the wider the scale of perception of the traditional cultural landscape and built heritage. In a region with local traditions that are alive and followed in everyday life, and a local economy that is mainly based on agriculture, the entire settlement structure is perceived as cultural heritage. In such areas, alternative uses should be found for redundant buildings. In contrast, in regions where the culture is less visible and alive nowadays and where the local economy has changed, people tend to perceive single buildings as representing their cultural heritage, and they often wish to preserve and conserve such remaining houses, barns and stables. In the study, we show that from a social science point of view, there is no universal perception of the maintenance of built cultural heritage. Rather, we see different views and opinions that are important to consider when it comes to developing heritage protection strategies together with public authorities.     

Capital maintenance and depreciation over the business cycle

This paper develops and estimates a stochastic general equilibrium model with capital maintenance, which affects endogenously the depreciation rate of capital. The estimate of maintenance series is found to track survey-based measures for Canada quite closely and to generate the procyclical pattern of maintenance observed in the data. We use our model estimates to infer the time profile of equipment capital depreciation in Canadian and US manufacturing. The depreciation rate is estimated to be volatile and highly procyclical in both countries.     

浅谈医院信息系统的安全维护

医院信息系统（HIS）在当今医院管理中发挥着不可替代的作用。该系统的广泛应用,给医院带来了巨大的经济效益。然而,一旦HIS系统运行出现问题,将给医院带来不可估量的损失,因此必须从中心机房、网络设备、服务器及数据库管理、病毒防范等方面采取相应的安全维护措施,以保障HIS系统的安全运行。     

我国大豆种植户持续种植意愿的影响因素——基于山东省农户的调查问卷

基于2010年对山东省334户大豆种植户的调研问卷数据,采用Logit模型,分析了在有限耕地面积的约束下影响大豆种植户持续种植意愿的因素。结果表明:大豆播种面积、农业收入占家庭收入的比重、每亩物质投入成本、是否有2年及2年以上大豆种植经验、从事农业劳动力的人数、大豆商品率这6项指标显著影响个体农户持续种植大豆的行为。     

内蒙古草原生态补偿意愿的实证研究

草原生态补偿意愿是确定草原生态补偿标准的重要参考,理论上补偿意愿包括补偿主体的支付意愿和补偿对象的受偿意愿。利用条件价值评估法(CVM)研究补偿主体的支付意愿和补偿对象的受偿意愿。通过采用SPSS软件中的皮尔逊相关分析法得出如下结论:内蒙古地区居民对草原生态补偿的支付意愿是23.10元/hm2.年;内蒙古草原牧区牧民的受偿意愿是1 944.75/hm2.年。影响支付意愿的因素主要是被访者的受教育程度(即学历水平)、对草原生态环境的认知程度和家庭人口;影响受偿意愿的因素主要是牲畜饲养方式和牧民居住地距离旗政府所在地的距离。     

夫妻共同遗嘱的效力及其立法建议

夫妻共同遗嘱在本质上属于共同法律行为。立法应有条件地承认共同遗嘱的效力,从法律上确认夫妻共同遗嘱的法律地位,并明确规定共同遗嘱的适用范围、适用主体、遗产范围、生效和失效、法律效力、变更与撤销以及执行等,从主体和内容两方面对夫妻共同遗嘱的适用和操作进行必要的规范。
