中央企业上市公司环境责任与公司价值的相关性研究

本文以中央企业上市公司为样本,讨论国有企业环境责任与公司价值之间的关系。文章在控制公司规模、行业竞争力等变量的条件下,回归结果发现：中央企业上市公司环境责任与公司价值之间存在正相关关系,但不显著。因此,很难认为公司承担更多环境责任能够促进公司价值的增长。     

Semiparametric estimation of multi-asset portfolio tail risk

When correlations between assets turn positive, multi-asset portfolios can become riskier than single assets. This article presents the estimation of tail risk at very high quantiles using a semiparametric estimator which is particularly suitable for portfolios with a large number of assets. The estimator captures simultaneously the information contained in each individual asset return that composes the portfolio, and the interrelation between assets. Noticeably, the accuracy of the estimates does not deteriorate when the number of assets in the portfolio increases. The implementation is as easy for a large number of assets as it is for a small number. We estimate the probability distribution of large losses for the American stock market considering portfolios with ten, fifty and one hundred assets of stocks with different market capitalization. In either case, the approximation for the portfolio tail risk is very accurate. We compare our results with well known benchmark models.     

民团、学校与公所--1930年代广西乡村基层政权之建构

1930年代，新桂系重新掌握广西政权之后，大力推行基层建设。改造民团、设立公所、建立学校，并实行“三位一体”，将基层的公所、民团、学校三种权利网络有机统一起来；同时，又培训青年知识分子担任基层干部，从而建立和健全了基层政权组织体系，稳固了在乡村的统治基础，成为近代乡村社会国家化较为成功的案例。     

Topical modelling issues in Solvency II

The main reasons for giving European insurance companies the option to apply internal models for calculating the main solvency requirement within the Solvency II framework is to enhance better risk management in the firms, and to provide the opportunity to derive a more accurate risk-oriented capital requirement than the standard Solvency Capital Requirement (SCR) could provide. The possibility to use internal models within pillar 1 basically means freedom to calculate the solvency requirement using some other formula and even principles than those given by the standard formula. This freedom is more limited with partial models.

This paper gives a brief introduction and update to the Solvency II project, reviews and discusses some topical aspects of internal models from the supervisory point of view, and points out some relating results of the Quantitative Impact Studies carried out, thus far, in the EU by CEIOPS.

Impacts of considering climate variability on investment decisions in Ethiopia

Extreme interannual variability of precipitation within Ethiopia is not uncommon, inducing droughts or floods and often creating serious repercussions on agricultural and nonagricultural commodities. A dynamic climate module is integrated into an economy‐wide model containing a detailed zonal level agricultural structure. This coupled climate‐economic model is used to evaluate the effects of climate variability on prospective irrigation and infrastructure investment strategies, and the ensuing country‐wide economy. The linkages between the dynamic climate module and the economic model are created by the introduction of a climate‐yield factor (CYF), defined at the crop level and varied across Ethiopian zones. Nine sets of variable climate (VC) data are processed by the coupled model, generating stochastic wet and dry shocks, producing an ensemble of potential economic prediction indicators. Analysis of gross domestic product and poverty rate reveal a significant overestimation of the country's future welfare under all investment strategies when climate variability is ignored. The coupled model ensemble is further utilized for risk assessment to guide Ethiopian policy and planning.

优化营商环境的财税政策研究——以江苏省为例

近年来,江苏财政部门积极支持营商环境建设,贯彻落实减税降费政策,采取设立风险补偿资金池、引导社会资本投资、设立支持企业发展的奖补资金等举措,在优化营商环境方面取得一定成效,但在政策执行过程中还存在一些不足,如部分行业税负可能上升、无定价权的企业在税制改革中获益相对较少、减税降费"降成本"效应下降等,针对实际工作中存在的问题,还需要进一步增强"降成本"政策的协调性,采取完善增值税抵扣机制等措施。     

债券融资支持工具实践路径研究--基于2018~2019年浙江省民营企业数据

为稳定和促进民营企业发债融资,以市场化方式帮助缓解民营企业融资难,2018年,国务院常务会议决定设立"民营企业债券融资支持工具"。基于此背景,本文选取民营企业债券融资支持工具作为研究对象,分析其实践机制,并以浙江为例探索实施民营企业债券融资支持工具的实现路径和难点所在。研究发现:浙江债券融资支持工具的实践探索持续协调发展,在创设主体、标的债务、凭证定价等三方面呈现趋优转向,但其发展仍受认知差异、计量规则、风险偏好、预期收益等复杂因素影响。     

Intangible assets and value relevance: Evidence from the Portuguese stock exchange

We assess the value relevance of the amounts for identifiable intangible assets and goodwill reported in the financial statements of all non-finance companies listed on the main market of the Portuguese Stock Exchange from 1998 to 2008. Additionally, we use panel data to explore the impact on value relevance of Portugal’s formal adoption of International Accounting Standards [IAS] and International Financial Reporting Standards [IFRS] in 2005. A distinctive feature of the accounting by our sample companies is that when they adopted IAS 38 and IFRS 3 in 2005, they were no longer required to recognise some intangible assets (such as start-up costs and research expenditures) and were no longer required to amortise goodwill.We find that net earnings, reported goodwill and other intangible assets are highly significantly associated with stock price. However, whereas earnings are related positively to stock prices when Portuguese Generally Accepted Accounting Principles (GAAP) were applied prior to 2005, the value relevance of earnings appears to have declined after the adoption of IAS/IFRS in 2005. Although the change to IAS/IFRS had no impact on the value relevance of identifiable intangibles as a whole, the evidence suggests that there was a positive effect on the value relevance of goodwill. When the subclasses of identifiable intangible assets are considered, we found evidence of an increase in value relevance of goodwill, other intangible assets, and research and development expenditures.
