机会主义造成了美国次贷危机

本文运用机遇管理理论,在简要回顾美国次贷危机的形成过程的基础上,从行为科学角度分析了当前美国这场金融危机形成的原因.在眼前利益的驱动下,美国的低收入阶层、金融机构以及美国政府,一致采取了机会主义的行为,互为因果,风险放大,导致严重共输的结局.这种上下协同的机会主义有体制和社会文化的根源.我们应从中吸取教训,按照机遇和风险运动的规律,警惕机会主义情绪,遵循凡事适度的原则,处理好各种关系,保持中国经济稳定健康的发展.

交易成本对易货经济的影响——瓦尔拉斯均衡“不成立”的一种情形

本文首先用一种新的解析几何方法在易货经济 (即两种商品的纯交换经济 )条件下的一般均衡框架下揭示了价格与消费者的马歇尔需求之间的函数关系。在此基础上 ,由个人承担的交易成本被直接置入。然后 ,本文证明 :如果交易成本的固定项不为零 ,供、求函数将不连续 ;如果同时有非无穷小比例的人口进行同步化决策 ,那么瓦尔拉斯均衡将会被破坏

The asymmetric information and price manipulation in stock market

The interaction between asymmetrically informed traders has been mostly investigated in theoretical frameworks. Not only there are relatively few empirical studies but, if any, the mostly focus on cross-sectional analysis and use very short samples. In this study, we blend theoretic with empirical, and propose a new signalling system of turning points in the economy to examine the extent of volatility of these markets relative to their tranquil periods. The signalling system proposed here is based on the Markov-switching model. Differing from the existing literatures, the study employs three phases and time-varying transition probability, and captures the states of volatility. After examining the causality between high volatility and foreign portfolio investment (FPI) by using moving average and generalized autoregressive conditional heteroskedasticity, the portfolio's profitability of FPI and individual investors in different periods are compared. Finally, the investigation of FPI's leading effect is studied.     

中国省级区域国际旅游竞争力决定因素分析

基于理论分析提出了影响我国省级区域旅游目的地国际旅游竞争力的8个决定因素,即旅游资源、旅游资本、旅游业劳动力、政府作用、企业能力、旅游产业结构、基础设施和区位条件。以我国31个省(区)为样本,利用基于面板数据的多元线性回归分析方法,从实证角度定量研究了上述8个决定因素对省级区域国际旅游竞争力影响的显著性及其相对重要性。回归结果显示:我国各省(区)国际旅游竞争力来源的98.5%能够由8个决定因素解释;除旅游产业结构外,其他决定因素对各省级区域国际旅游竞争力的影响均在0.01的水平上显著。

Improving Estimates of Inequality and Poverty from Urban China's Household Income and Expenditure Survey

In urban China the Household Income and Expenditure Survey requires respondents to keep a daily expenditure diary for a full 12-month period. This onerous reporting task makes it difficult to recruit respondents, compromising the sample. This article uses monthly expenditure data from two urban areas of China to see if data collection short-cuts, such as extrapolating to annual totals from expenditure reports in only some months of the year, would harm the accuracy of annual expenditure, inequality and poverty estimates. Replacing 12-month diaries with simple extrapolations from either one, two, four or six months would cause a sharp increase in estimates of annual inequality and poverty. This undermines international comparisons of inequality statistics because no country other than China uses such comprehensive 12-month expenditure records. But a corrected form of extrapolation, based on correlations between the same household's expenditures in different months of the year, gives much smaller errors in estimates of inequality and poverty.
