对股市泡沫成因的博弈分析

股票市场泡沫是经济活动过程中存在的必然产物。本文将运用博弈论的观点来解释股市泡沫的成因。     

上市公司“庄股跳水”预测模型的实证分析

预防"庄股跳水"是投资者在中国股市中生存的必修课,同时也是股市行为研究的难点之一.本文选取2000年到2003年深市遭遇跳水行情的股票及与之相对应的非跳水股票各31只股票为样本,运用t检验、判别分析和主成分分析等多种计量方法和模型对两类股票的各种重要指标进行了详细分析、比较及预测.实证研究发现两类股票的各种重要指标存在重大差异,并且模型能够以较高的准确率预测"庄股跳水".     

Periodic integer-valued bilinear time series model

This paper deals with the study of some probabilistic and statistical properties of a periodic integer-valued diagonal bilinear model. The existence of a periodically strict stationary integer-valued process is shown. Sufficient conditions for the periodically stationary, both in the first and second orders, are established. The closed-forms of the mean and the second moment are obtained. The closed-form of the periodic autocovariance function is established. The Yule–Walker estimations of the underlying parameters are obtained. A simulation study is provided.

论上海发展面临的虚拟经济膨胀问题

今年上海经济增量部分出现的高度依赖股市、房市的新现象,是与国际大环境特别是全球流动性过剩高度相关的,而当前虚拟经济扩张对上海发展而言是一把双刃剑,既给经济发展带来一定机遇,也可能加剧资产泡沫的风险。从实现"四个率先"的战略高度出发,虚拟经济膨胀不利于上海转变增长方式。上海未来要加快经济增长转型,就必须聚焦发展服务经济,通过服务升级与创新,完善城市功能,进一步推动三、二、一产业的融合发展。同时,面对目前较复杂的经济发展环境,本文还提出了化解风险,加快经济转型的相关对策建议。

Mutual-Fund Benchmarking and Market Bubbles: A Behavioral Approach

Dynamics of equity risk premium is not directly measurable on the market. Numerous studies and empirical research analyse its volatility also considering the time span, concluding that the dynamics of equity risk premium over time is inversely proportional to the economic cycle. This study analyses the passive role that, implicitly, would place institutional investors in such a context. In reality, savings management is delegated to a small number of professional operators (institutional investors), as opposed to pure theoretical models in which every person can act directly on the market thus ensuring unlimited price elasticity. Institutional investors should be rational and completely informed so that they can assume an anticyclical position on the market. Thus, supply and demand should quickly smooth over emerging price pressures and avoid price bubbles. We analyse one possible explanation for this situation not to occur, namely, that professionals suffer from operational limits that prevent them from doing their job in the best possible way. Using empirical evidence from the Italian Stock Exchange (Comit Index), we conclude that three factors reduce the freedom of institutional investors to manage their portfolios – the market target size, the fund structure, and the benchmarking – and discuss some implications for each of them.     

The Bubble Game: An Experimental Study of Speculation

We propose a bubble game that involves sequential trading of an asset commonly known to be valueless. Because no trader is ever sure to be last in the market sequence, the game allows for a bubble at the Nash equilibrium when there is no cap on the maximum price. We run experiments both with and without a price cap. Structural estimation of behavioral game theory models suggests that quantal responses and analogy‐based expectations are important drivers of speculation.     

汇率与股票资产价格泡沫关系的实证分析及货币政策研究

文章首先分析了人民币汇率和我国股票资产价格(以上证A股为例)的现状,然后就人民币汇率升值和上证A股股价变化关系进行了实证研究,其中包含了金融危机的影响。实证结果表明,从长期来看本币升值将导致股票资产价格泡沫下降;接着通过建立应对汇率升值导致的股票资产价格泡沫的货币政策模型得出,当出现资产价格泡沫时,多数情况下应实行紧缩货币政策,以免资产价格泡沫在短期趋于过大,减轻资产价格泡沫经长期后破灭产生通货紧缩等更大的不利影响。     

美联储新一轮量化宽松货币政策对中国的影响

美联储于2010年11月4日宣布推出第二轮量化宽松货币政策（QE2）,这对新兴市场的流动性产生了巨大的冲击。QE2通过国际利差、美国国债回购、跨国企业FDI等渠道迫使人民币升值,同时过剩的流动性会对我国资产价格产生较大的外部压力。特别需要指出目前我国普遍存在的行业低利润现象会推高资产价格并放大人民币升值产生的不良后果。
