Meat consumption has increased significantly in the last 50 years. This trend raises various health and environmental issues, as well as moral concerns regarding farm animal welfare. In this paper, we discuss the regulation of meat consumption in developed countries. Specifically, we discuss possible justifications for this regulation in terms of environmental, health and animal welfare considerations, as well as the effect of fiscal, informational and behavioral regulatory instruments. Finally, we present a list of challenges that policy makers and food scholars may need to confront in the future.  相似文献

以创新生态系统为视角,引入创新资源互动与生态系统规范机制为中介变量和调节变量,探究价值共创如何影响企业创新绩效。基于307家企业样本数据,运用结构方程模型、Bootstrap和层级回归方法对数据进行分析。研究发现:创新生态系统中,价值共创不完全直接影响企业创新绩效;创新资源互动部分中介价值共创对企业创新绩效的影响;生态系统规范机制部分正向调节价值共创对创新资源互动的影响。最后提出,创新生态系统调控方与企业要差异化地制定提升创新绩效的实施方案,营造活跃的创新资源互动氛围,形成并完善系统内生态规范机制。  相似文献

“十四五”规划提出建设人与自然和谐共生的现代化,这要求持续推进污染减排促进经济绿色低碳转型,实现环境与经济协同发展。基于2007年起排污费提高的政策冲击和2004-2013年工业企业污染数据,本文使用倍差法考察排污费提高的污染减排效果以及融资约束对政策效应的影响。研究发现排污费提高后,污染排放水平显著下降,但产出也受到较大冲击;企业减排方式存在明显差异,大型企业主要通过降低污染强度的方式来降低污染排放,而中小型企业则主要采取降低生产规模的方式来降低污染排放;进一步基于环境投融资角度对企业减排行为的分析揭示,融资约束影响中小企业污染减排,加剧排污费提高对产出的影响。因此,提高绿色金融的环境投融资供给能力是促进经济绿色转型的重要途径。  相似文献

Whilst there are many models discussing the mechanics of financial crises, the notion of predation seems to be insufficiently taken into consideration as one of the explanatory behavioral factors, although it would enrich the understanding of dysfunctional financial markets. This paper provides a stylized model for disruptive and toxic economic behaviors in the context of predatory markets like the subprime crisis of 2007–2009. In this context, we investigate why consumers and sellers buy products they know to be toxic. Conventional economic models contain classical tenets that assume that consumers are rational and search for utility maximization; however, these models cannot straightforwardly explain the behaviors consumers and sellers adopted during times of financial crises, known as “exuberantly irrational”. Hence, we use and expand on a predator-prey perspective that endeavors to capture such behaviors more effectively while showing that four market variables must be considered together over time – consumers, suppliers, toxic products and regulations. Our analysis shows that during the GFC, consumers and lenders as well as regulators embraced whole-heartedly, and contrary to common economic sense, the development and marketing of toxic products. Their behaviors were actually quite rational in the context of a poisoned market. Such observation could assist in drafting regulations.  相似文献

制造业绿色转型是大势所趋,环境规制作为实现环境效益的重要手段,其如何影响制造业绿色转型值得探讨。在阐述环境规制对制造业绿色转型直接影响和间接影响机制的基础上,使用2005—2017年中国(内地)省级面板数据,采用基于EBM-GML模型计算得出的绿色全要素生产率衡量中国制造业绿色转型程度,进而建立固定效应面板模型检验异质性环境规制对制造业绿色转型的影响。结果表明:我国制造业绿色转型程度整体保持上升趋势,增长速度呈现出明显阶段性特征。环境规制对制造业绿色转型具有非线性影响,命令控制型环境规制和自愿参与型环境规制超过一定限度后能直接加快制造业绿色转型进程,市场激励型环境规制的直接影响则不显著;环境规制能够通过技术创新、外商直接投资、产业结构间接促进制造业绿色转型,产业集聚的影响则不显著;市场激励型环境规制能够通过间接效应影响制造业绿色转型。  相似文献

We examine whether the degree of selective disclosure (as measured by information leakage prior to managerial earnings guidance) of foreign firms with ADRs is different from that of U.S. firms. We find that there is no variation of leakage before earning guidance between ADRs and U.S. firms. This result is consistent with the prediction that, despite being exempt from Regulation FD, ADRs have sufficient incentives to avoid selective disclosure even without the regulatory enforcement. In addition, we attempt to determine whether the variation in selective disclosure among the foreign firms with ADRs is conditioned on the respective home country transparency and governance standards. We find that country-specific characteristics, such as corruption perception, economic freedom and the legal system origin, explain the variation in information leakage of ADRs.  相似文献

科技创新规模扩张和科技创新效率提升是增强国家科技创新能力的两条关键途径。基于现有研究鲜有结合科技创新规模和科技创新效率开展国家科技创新能力评价的现状,采用因子分析法,系统筛选国家科技创新规模影响因素,并结合科技创新效率影响因素,完善国家科技创新能力评价指标体系,通过构建DEA Malmquist指数模型,评价不同时期国家科技创新效率变化指数,以及中国与全球10个国家科技创新能力的时空差异性。研究表明,R&D投入强度、R&D研究人员、专利申请量、科技期刊文章数、高科技产品出口额占制成品出口总额的百分比、科技创新效率是影响国家科技创新能力的关键指标;1991-2014年中国科技创新能力水平呈指数增长态势,有力提升了国家科技实力;全球10个国家科技创新能力水平除日本出现一定波动外,其余九国整体呈小幅递增态势。  相似文献

In this paper key regulation-related findings and commentaries in the 2016 academic literature are synthesized in annotated form. This paper is one in a series of previously published annotated bibliographies published in this journal. Papers published in academic outlets including The Accounting Review, Journal of Accounting Research, Journal of Accounting and Economics, Contemporary Accounting Research, Accounting Horizons, The Journal of Accounting, Auditing & Finance, Journal of Accounting and Public Policy, Journal of Business, Finance & Accounting, The Journal of Financial Reporting, Auditing A Journal of Practice and Theory, and Research in Accounting Regulation were reviewed for potential inclusion. The 2016 literature featured strong regulation-related threads as follows: financial accounting regulation, analysis of individual pronouncements, SEC regulatory activity and its impact, international financial reporting standards, income tax reporting, and auditing.  相似文献

Over the past two decades, the regulatory landscape for non-GAAP reporting has evolved significantly. Despite a temporary decline in the frequency of non-GAAP reporting following Regulation G, the incidence of non-GAAP disclosure has continued to increase steadily, leading to a current all-time high in reporting activity. This proliferation of non-GAAP disclosure has captured the attention of standard setters and regulators in recent years. This paper provides an academic perspective on policy implications for both regulation and standard setting. We contend that current Compliance and Disclosure Interpretations (C&DIs) of the SEC staff may perhaps have gone too far in restricting certain types of non-GAAP disclosures. As a result, we advocate a slight relaxation of the current enforcement of Regulation G. We agree with FASB proposals for greater disaggregation in the income statement to allow for more transparency in non-GAAP reporting. Finally, we believe the PCAOB should consider requiring auditors to take a more direct role with respect to non-GAAP disclosures.  相似文献

基于事件系统理论构建系统性、多层次性和综合性的政策量化分析框架,从政策属性、政策目标和政策工具3个维度对我国1985—2015年制定的198条环境规制科技政策进行量化研究。基于政策评估中的工具理性和价值理性两个层面,从环保科技进步效果和经济增长效应两个维度对环境规制科技政策有效性进行评估。研究发现,我国环境规制科技政策工具及政策工具协同对环保科技进步和经济增长的影响存在显著方向性差异。为此,进一步讨论了我国环境规制科技政策工具及工具协同的政策有效性评估结果,可为我国环境规制科技政策的完善和有效实施提供决策依据。  相似文献
