Where classical economics integrates the quantity theory of money with the concept of Ricardian equivalence, the tendency of recent macroeconomic presentations is to focus either upon money and inflation or upon taxation and debt. That neglect of classical monetary–fiscal integration is surprising, given an initiative by the International Monetary Fund that set credit, money, and fiscal policy within a single structure. This article places those ‘credit counterparts of broad money’ in the context of the Great Depression and the recent global financial crisis. The upshot is a set of conclusions: that, to counter the prospect of deflation, quantitative easing is a weak policy response; that fiscal deficits are better; and that cuts in taxation are preferable to increased government spending.  相似文献

City governments are embracing data-driven and algorithmic planning to tackle urban problems. Data-driven analytics have an unprecedented capacity to call urban futures into being. At the same time, they can depoliticize planning decisions. I argue that this shift calls urban studies scholars to investigate geographies of algorithmic violence—a repetitive and standardized form of violence that contributes to the racialization of space and spatialization of poverty. This article examines this broader phenomenon through the case of a proprietary market value assessment that is being used to guide development in cities across the United States. The assessment employs an algorithm that helps city officials make critical decisions about which neighborhoods to target for investment, disinvestment and public service upgrades or disconnections. I argue that the racial, infrastructural, and epistemological violence associated with this evaluation can potentially lead to a new kind of municipal redlining. The article brings insights from critical race theory into conversation with critical scholarship on algorithms by analyzing how algorithmic violence works through data-driven planning technologies to depoliticize and leverage power while further entrenching racism and inequality.  相似文献

This article presents the intellectual structure and 25‐year author cocitation analysis of the journal Business Strategy and the Environment. The findings show that Business Strategy and the Environment is an emerging, well‐established journal in its field. The journal needs a core set of authors who are actively engaged in the production and certification of knowledge; further, it consists of a number of loosely linked research team contributors, each with its own areas of interest. The existence of these research teams is a sign of strength that characterizes the journal as it strives to foster a community of unified scholars whose published works advance our understanding of business strategic decisions and behavior with regard to the natural environment. This study is useful for contributors, readers, and editorial board members who form the journal's community of knowledge creation and certification.  相似文献

文章运用产业上游度测度模型,测度了我国住宿和餐饮业在产业链上位置,考察了其在产业链上位置的动态变迁。总体来讲,住宿和餐饮业在全球产业链上和国内产业链上的位置都向产业链上游移动。从封闭经济到开放经济,住宿和餐饮业的产业上游度存在着较大波动,2002—2010年全球产业上游度都大于其国内产业上游度;2012—2017年则相反,住宿和餐饮业国内产业上游度波动幅度要大于其全球产业上游度波动幅度。住宿和餐饮业净出口变化方向与其国外产业上游度变化方向基本相同,净出口增加对其国外产业上游度上升有促进作用。住宿和餐饮业全球产业上游度变化趋势与其国内产业上游度变化趋势基本相似。总体来讲,现阶段住宿和餐饮业国内产业上游度增长速度要大于其全球产业上游度增长速度。  相似文献

泸县农村宅基地有偿使用制度改革效果评价   总被引:1,自引:0,他引:1  
[目的]宅基地有偿使用制度研究有利于推进宅基地制度改革,缓解无偿无限期带来的土地超占乱占和闲置问题。[方法]文章运用层次分析法和模糊综合评价法对2016年和2018年泸县农村宅基地有偿使用制度改革政策效果进行评价。[结果]政策的开展能有效推进村民自治建设进程,但政策的实施要注重公开透明性;有偿使用政策能有效缓解一户多宅、低效闲置、超占乱占等土地浪费现象实现土地的节约集约利用;政策的实施能有效地改善基础设施和农村面貌,但对泸县生产方式转变、新业态发展、农户生活水平提升影响力较小;总体来看农户对有偿使用政策满意度和支持度较高。[结论]针对当前有偿使用制度改革,该文认为宅基地有偿使用制度改革还应该完善有偿使用费收取管理政策,增强政策执行透明度;注重基层队伍建设,实现有偿使用费保值增值;合理选择安置模式,发展农村新业态;加强宅基地有偿使用与有偿退出的高效联动,推进宅基地制度改革进程。  相似文献

日语自他动词是日语语法中的一个难点,尤其在和其他语态相关联时使用起来更加有难度.以汉语为母语的日语学习者,常常按照汉语思维习惯去套用日语,出现误用现象.本文从自他动词与被动表现、使役表现和可能表现相关的误用三方面入手,归纳总结中国的日语学习者常见的错误,并从社会文化心理方面探讨产生这些误用的原因,以期帮助中国学生解决有关母语干涉的问题.  相似文献

Ever since the first introduction of the expected discounted penalty function (EDPF), it has been widely acknowledged that it contains information that is relevant from a risk management perspective. Expressions for the EDPF are now available for a wide range of models, in particular for a general class of Lévy risk processes. Yet, in order to capitalize on this potential for applications, these expressions must be computationally tractable enough as to allow for the evaluation of associated risk measures such as Value at Risk (VaR) or Conditional Value at Risk (CVaR). Most of the models studied so far offer few interesting examples for which computation of the associated EDPF can be carried out to the last instances where evaluation of risk measures is possible. Another drawback of existing examples is that the expressions are available for an infinite-time horizon EDPF only. Yet, realistic applications would require the computation of an EDPF over a finite-time horizon. In this paper we address these two issues by studying examples of risk processes for which numerical evaluation of the EDPF can be readily implemented. These examples are based on the recently introduced meromorphic processes, including the beta and theta families of Lévy processes, whose construction is tailor-made for computational ease. We provide expressions for the EDPF associated with these processes and we discuss in detail how a finite-time horizon EDPF can be computed for these families. We also provide numerical examples for different choices of parameters in order to illustrate how ruin-based risk measures can be computed for these families of Lévy risk processes.  相似文献

This paper explores the determinants of financial development by focusing on the role played by barriers to the diffusion of financial technology. These barriers are measured using human genetic distance from the technology frontier. The results based on cross-sectional data for 123 countries suggest that genetic distance to the global frontier has an economically and statistically significant effect on financial development, in that countries that are genetically far from the technology leader tend to have lower levels of financial development. Genetic distance is found to have the largest effect, even after controlling for other determinants of financial development established in the literature. These findings indicate that cultural barriers to the diffusion of financial technology across borders impact financial development by influencing the follower countries’ ability to adopt and adapt innovations from the frontier.  相似文献
