WTO背景下我国农产品期货业发展

由于农产品供给的季节性和农产品生产的地域性,导致不同时间、不同地区同种农产品的价格变化较大,怎样规避农产品现货市场上这种价格变化带来的风险?我国已经加入WTO,五年过渡期过后,期货市场将全面放开,我国农产品期货市场将面临哪些机遇,又将受到那些挑战?文章在这些方面进行了分析,并提出了进一步发展我国农产品期货市场的建议。     

股票停牌、涨跌停与ETF定价效率——基于上证50ETF日度数据的实证研究

本文应用中国股市2007年至2011年的数据,研究了上证50ETF市场价格和基金净值的相关关系,以及折溢价水平及其影响因素。基于ETF的申购赎回和交易机制,在成分股涨跌停板和停牌期间,由于ETF二级市场价格具有价格发现功能,ETF市场价格可能较大偏离(形式上的)ETF净值,造成ETF的异常折溢价,而此类异常折溢价并不是真正的套利机会。另外,上证50ETF的市场价格与基金净值存在显著同步变动的关系;在涨跌停板和停牌期间之外,上证50ETF的折溢价水平低于套利所需的交易成本。本文研究表明,上证50ETF具有较高的定价效率。     

资产价格泡沫研究述评:实验金融学视角

本文从实验金融学的视角介绍了资产泡沫最新的定义和分类,阐述了投机性泡沫、理性泡沫与非理性泡沫之间的区别和联系,着重从信息对称、信息不对称、有限套利泡沫、异质信念和实验金融五个方面系统评述了资产价格泡沫理论的发展历程和新进展,指出该领域进一步的研究方向和中国开展资产价格泡沫研究的重要意义。研究表明,随着现代金融学的高速发展,学界对资产泡沫的研究日益深入。特别是非理性和实验金融学视角的引入,突破了传统金融框架的束缚,为这一课题研究带来了新的认知和理解。即便如此,目前仍无法根除资产泡沫产生的可能性。很多相关问题,如资产泡沫产生的时间和根本原因,仍然等待着学者们去探索和研究。     

股指期货对A股波动性的影响

鉴于GARCH模型适合研究金融时间序列的方差随时间变化的情况,笔者采用该模型研究股指期货的推出能否减少股票市场的波动性。本文选取股指期货推出前后一年的沪深300指数的日收盘价作为原始数据,通过建立GARCH模型就股指期货对股票市场波动性的影响进行了实证研究,结果显示,股指期货的引入在一定程度上降低了我国股票现货市场的波动性,但不显著。     

我国商业银行业务的国际化进展

On the pricing of real estate index linked swaps

In this paper we discuss the pricing of commercial real estate index linked swaps (CREILS). This particular pricing problem has been studied by Buttimer et al. in a previous paper in this journal (6 [1997]: 16). We show that their results are only approximately correct and that the true theoretical price of the swap is in fact equal to zero. This result is shown to hold regardless of the specific model chosen for the index process, the dividend process, and the interest rate term structure. We provide an intuitive economic argument as well as a full mathematical proof of our results. In particular we show that the nonzero result in the previous paper is due to two specific numerical approximations introduced in that paper, and we discuss these approximation errors from a theoretical as well as from a numerical point of view.     

人民币国际化的现实路径与机遇

随着中国经济的发展,国际影响力的提高,人民币的国际地位也随之提升,边境贸易助推人民币区域化,货币互换为增加境外人民币存量提供了制度安排,离岸中心为境外人民币提供了服务平台,人民币国际化在各个领域已经形成共识。受全球金融危机的影响,世界关键货币——美元持续疲软,国际能源价格持续下跌,给人民币国际化创造了难得的历史机遇,人民币加速国际化的呼声也越来越高涨。中国应利用人民币升值通道期,推动人民币国际结算功能实现;利用石油价格的下跌期,推动重要能源的人民币国际计价;利用中国全球贸易地位,树立人民币储备货币地位。     

资产透明度、监管套利与银行系统性风险

资产不透明的金融机构过度依赖批发性融资进行监管套利不利于系统性风险的防控。在此背景下,本文首先在经典银行道德风险模型的基础上引入关联性,从资产透明度和监管套利的视角分析银行系统性风险累积的内在机理。而后利用2007-2018年中国上市银行微观数据,构建资产透明度指标和系统性风险指标(SRISK、MES),对理论推论进行实证检验。主要结论有:(1)资产不透明、监管套利会提高银行的系统性风险。(2)监管套利弱化了资产透明度和资本监管机制对银行系统性风险承担的约束作用,资产透明度与资本监管机制在约束系统性风险承担中的协调作用不明显。(3)以大银行为主的债权银行受监管套利的影响相较于受资产透明度的影响更明显。在此基础上,我们对完善金融风险防范体系以及监管机制提出了若干建议。     

Corporate environmental reporting: Are French firms compliant with the Task Force on Climate Financial Disclosures' recommendations?

This article deals with the practices of French corporate environmental disclosure with a focus on climate-related risks. In particular, it aims to analyse the compliance of CAC 40 firms with the recommendations of the Task Force on Climate-related Financial Disclosures (2017), an international initiative made up by Financial Stability Board to enhance financial transparency. On the basis of a content analysis of firms' reference documents spanning 2015–2018, we constructed the Climate Compliance Index (CCI) to evaluate whether firms disclose information on climate risks and opportunities about governance, strategy, risk management and metrics. Our results highlight a gradual increase of the CCI despite disparities across sectors and management areas. The content analysis allows us to develop a set of indicators frequently reported by domain and to identify and define climate risks and opportunities and their financial impacts per sector, which is a first step to improve the disclosure of non-financial information.     

Investor attention,firm-specific characteristic,and momentum: A case of the Korean stock market

This study examines the sources of negative momentum profits by combining investor attention and the properties of common and firm-specific factors. We choose the Korean stock market as a good case to characterize the negative momentum profits identified in Asia. In both portfolio and stock analyses, a method is devised to generate return data involving the property of each common and firm-specific factor within stock groups by investor attention. This study found significant negative momentum profits within the stock group with high investor attention. This momentum effect is highly dependent on the reversed performance of the past loser portfolio, not the continued performance of the past winner portfolio, and this reversal is strongly attributable to the properties of firm-specific factors, and not those of common factors. These results are robustly consistent regardless of changes in empirical design and the consideration of influence factors, market dynamics, and other stock markets.
