社会转型与观念变迁--以“道德缺失”为中心的考察

尽管“道德缺失”是转型期中国一个不容忽视的社会问题，但当代的“道德缺失”现象并非严重到了危机阶段，中国古代也不是“道德天堂”。今天的道德困境可以归因于社会环境的巨大变化。这种问题的解决，需依靠有效的维护机制作为保障。落实到根本，还是要大力发展经济，建设市民社会。     

地方政府重大决策机制存在问题及优化路径

地方政府作为地方公共事务管理者，决策正确与否直接关系到公共管理活动的成败，并且在一定程度上影响地方经济发展的水平及其核心竞争力。由于我国地方政府现阶段决策主体多元性及其职能模糊性，一些重大决策失误现象屡屡发生，造成了有限资源的巨大浪费，严重影响了地方政府在人民群众中的威信和形象。对此，我国地方政府迫切需要优化重大决策机制，包括明晰体制内外决策主体的职能、第三方评估、公众参与、决策终身责任追究及倒查机制等，以推进地方政府决策的民主化、科学化和法治化。     

Subjective utility with upper and lower probabilities on finite states

This article is concerned with thresholds of discrimination of preference judgments under uncertainty. We establish an axiomatic characterization for a threshold representation, where thresholds are represented by inexact measurement of subjective probabilities, i.e., upper and lower probabilities. Since upper and lower probabilities need not be additive, the representational form adopts the Choquet integration.

LOG-PERIODOGRAM ESTIMATION OF LONG MEMORY VOLATILITY DEPENDENCIES WITH CONDITIONALLY HEAVY TAILED RETURNS

Many recent papers have used semiparametric methods, especially the log-periodogram regression, to detect and estimate long memory in the volatility of asset returns. In these papers, the volatility is proxied by measures such as squared, log-squared, and absolute returns. While the evidence for the existence of long memory is strong using any of these measures, the actual long memory parameter estimates can be sensitive to which measure is used. In Monte-Carlo simulations, I find that if the data is conditionally leptokurtic, the log-periodogram regression estimator using squared returns has a large downward bias, which is avoided by using other volatility measures. In United States stock return data, I find that squared returns give much lower estimates of the long memory parameter than the alternative volatility measures, which is consistent with the simulation results. I conclude that researchers should avoid using the squared returns in the semiparametric estimation of long memory volatility dependencies.     

关于建立股指期货交易制度的构想

随着中国正式加入WTO ,推出股票指数期货已是确定的方向。目前中国建立股指期货交易制度不仅是必要的 ,也是可行的。股指期货作为一种金融创新产品 ,它的建立首先必须有统一交易场所 ,科学设计合约 ,同时也要进一步规范现货市场 ,培育交易主体 ,引入做空机制 ,规范会员结构 ,健全监管制度

Projective Identification as a Contributor to Domestic Violence

Many explanations have been given as to why men batter. Rarely are deep unconscious intrapsychic processes identified as contributing reasons. One way that violent men may use their partner to fill emotional needs is through the primitive defense of projective identification. Projective identification may be invoked by men to induce the other partner to carry split off threatening parts of the self that are too anxiety provoking to retain. The occurrence of projective identification could therefore be an important intrapsychic and interpersonal dynamic that contributes to the escalation of tension prior to the violent episode.     

区域经济一体化对世界福利及多边贸易体制的影响

随着经济的全球化,在以GATT和WTO为代表的多边贸易自由化不断深化的同时,区域经济一体化组织层出不穷。而区域经济一体化对于世界福利和多边贸易是有利有弊的。因此,在政策制定上要扬长避短,既限制其不利的影响,同时又要积极发挥它的积极作用。
