• 详情 信任与担忧:中国共同基金业执业能力评价
    对共同基金的执业能力的评价不仅可以帮助投资者进行科学的投资决策,同时还可以为管理层的政策制定提供理论依据。本文基于中国资本市场中共同基金的全部数据样本和全部时间周期,从讨论三个经典模型的科学性角度出发,比较不同模型实证结果的合理性,并对我国共同基金业的执业能力给出更加全面的评估。实证结果表明,我国共同基金业整体上不具备应有的执业能力;开放式基金的执业能力并没有明显优于封闭式基金;熊市中发行的共同基金整体上执业能力强于牛市中发行的基金。因此,建议管理层在共同基金发行的速度控制上,尽量避免在牛市中大量推出基金,而是应该在熊市中加大共同基金的发行力度,且不能简单地认为我国未来共同基金业的主流发展方向就是发展开放基金。
  • 详情 封闭式基金与股指期货套利交易的可行性分析
    本文首先对股指期货期现套利交易的原理进行概述,然后利用HS300指数与封闭式基金两年的历史数据,采用线性回归方法得出两者的相关性、相对风险系数,最后运用Johansen协整检验方法验证了基金组合与HS300指数的长期均衡性,根据跟踪误差最小化的原则确定基金组合的权重,由此论证了封闭式基金与股指期货套利交易的可行性。
  • 详情 中国开放式基金市场环境偏差效应研究
    市场环境偏差效应是指在基金绩效评估中忽视“市场环境信息”可能导致人们对基金绩效进行错误估计的现象。本文使用Pastor-Stambaugh方法,选取2002年1月-2007年12月期间130只开放式股票型基金的数据,来考察我国开放式基金的市场环境偏差效应问题。研究结果表明,我国开放式基金存在显著的市场环境偏差效应,市场环境信息对基金绩效度量有着重要影响。在使用Pastor-Stambaugh方法和市场环境信息对常用基金绩效指标进行进行修正后,基金绩效度量偏差有所减小,绩效排序不一致性问题也有所改善。
  • 详情 开放式基金流动和个股收益关系的实证分析
    本文通过构建度量流动变量的模型来研究开放式基金流动和股票收益之间的关系,研究发现开放式基金流动和股票收益之间存在着负相关的关系,流动越高的股票的未来收益越低,反之,流动越低股票的未来收益越高。通过对流动效应和价值效应以及动量效应做比较,发现他们是互不包含的影响基金收益的因素,这更加强调了基金流动和股票收益之间关系的稳定性。
  • 详情 The Theoretical Logic of Sovereign Wealth Funds
    Sovereign wealth funds (SWFs) form a new class of institutional investors with significant influence on the global financial market. Assets under management (AUM) of global SWFs totaled around US$3.0 trillion at the end of 2007, and are still rising. Three developments are behind the current cause of SWFs: First, reform of international monetary system is the core reason for the rise in SWFs; Secondly, the phenomenal raise of energy price is an important reason contributing in the expansion of SWFs; finally, the economic globalization facilitates SWFs’ operation. According to the model of "National Economic Man" model, the foreign reserve of a nation will increase sharply and gradually this nation will invest surplus wealth during the economic stage of early expansion or fast-growing stage. Whereas, with the decreasing of the production factors, accumulated wealth of a nation will gradually attain to peak. When the economy enters into wealth-oriented stage or the stage of sustainable low growth, the nation will increasingly rely on wealth accumulated by consumption, and incline to invest in risk-free assets. At present, the aims of SWFs are mainly focused on the following five aspects, including stabilization the national balance sheet for different periods, diversification of the central bank's reserves, smoothening inter-generation revenue of country, prevention of national socio-economic crisis and assistance of the government’s overall development strategy.
  • 详情 中国股票市场收益波动的非对称性研究
    本文采用EGARCH与TARCH模型,以2003年6月30日至2008年6月27日的上证综指和深证综指日收益率为研究样本,对中国股票市场价格波动的非对称效应进行了检验,证实了中国股票市场存在对信息反应的不平衡,即:“利空消息”对股票价格的冲击大于“利多消息”对股票价格的冲击。
  • 详情 汇率制度演变与宏观经济绩效:文献回顾
    本文回顾了利用不同汇率制度分类方法对汇率制度演变、假说与争议以及汇率制度与宏观经济绩效之间关系的研究。本文发现,一,由于汇率制度分类方法的不同,经验研究对汇率制度演变及其发展趋势得出了不同的结论;二,同样由于分类方法的不同,经验研究对不同汇率制度下的宏观经济表现也不能形成一致的看法,并且,经验结果与理论预测之间存在非常大的鸿沟;三,一国政府在汇率制度安排上的言行不一致极大地影响了一国的宏观经济绩效。这些发现促使经济学家重新审视不同汇率制度的优劣和对汇率制度选择的理论研究。
  • 详情 人民币最优汇率制度弹性的理论模型与经验估计——基于价格稳定视角的研究
    本文利用M-F-D框架,建立了一个带有随机冲击的小国开放经济模型,考察了以价格稳定和汇率稳定作为汇率制度选择标准时最优的人民币汇率制度安排。研究发现,政府不同的汇率政策目标会导致不同的汇率制度安排:以价格稳定作为人民币汇率制度选择的基本标准,人民币最优的汇率制度安排是某一内解所代表的中间汇率制度;以名义汇率稳定作为标准,最优的制度安排则是固定汇率制度。在理论模型基础上,本文利用OLS方法估计了模型的基本参数,经验地估计了价格稳定目标下人民币最优的汇率制度弹性。研究认为,为了稳定价格,中央银行应尽可能地让汇率变化来吸收外汇市场压力,人民币汇率制度应该向更具弹性的方向转变。
  • 详情 Endogenous Timing and Banking Competition in a Mixed Oligopoly:A Theoretical Perspective on the Banking Industry in China
    Based on the background of the banking industry in China, this paper establishes Cournot, Bertrand and Stackelberg mixed oligopoly competition models with deposit and interest rates as strategic variables between a representative state-owned bank and a representative foreign bank. We discuss and compare the equilibrium deposits, interest rates and profits in different market structures. More importantly, considering the endogenous timing setup and taking the extended game with observable delay as the basic model, we analyze the competition results of the mixed duopoly at different market structures and make numerical simulations in order to get the outcomes of the extended game. It is found that, in the deposit competition with endogenous timing, if two banks have the same deposit return rate, the simultaneous move could become the final result; If the deposit return of the foreign bank is more than twice that of the state-owned bank, all SPNEs of the extended game are sequential, i.e one bank will lead, the other will follow. If the state-owned bank’s profit in Cournot is larger than that of the state-owned bank as the Stackelberg follower, the only SPNE will be (E, L), i.e. the state-owned bank will lead and the foreign bank will follow. Additionally, in the interest rate competition with endogenous timing, if the degree of nationalization is no larger than 75% as well as two banks have the same deposit return rate, the final SPNEs of the extended game are sequential and the simultaneous move can not become the SPNE.
