从美国房价走势透视中国房地产市场走向

内容文章从量化分析的角度出发,研究了全美50个州和哥伦比亚特区房价指数序列的记忆性特征,发现各州房价指数序列均具有一定程度的长记忆性.同时,我们对50个州房价指数记忆参数的估计值进行了聚类分析,由此发现各州房价指数的记忆性呈现出一定的地区聚集性特征,而且还与地区的人口密度存在一定关系,从而为宏观政策制定者在决定房价调控措施的时候提供了有益的新思维,可使楼市更加健康稳定地发展.此外,文章的研究结果对于解决我国房地产市场目前存在的巨大泡沫问题提供了一个全新的视角     

Enforcing and re-enforcing trust: Employers,managers and upper-white-collar employees in Finnish manufacturing companies, 1920–1980

In this article employee–employer relations with respect to upper-white-collar employees in Finnish large-scale companies are investigated. The period is from the 1920s to the 1980s. The article shows that the employee–employer relations were during the whole period based on mutual trust. In spite of significant transformations in the labour market practices and in interest formulation and unionisation among these employees, it was in the interests of both parties to maintain these trustful relations. However, the tools with which to maintain such relations changed and adapted. The process was not easy, and was marked by elements of conflict and tension. The elements of trust had to be actively strengthened and rebuilt, especially in the 1960s and 1970s. But as the post-war economic and societal model was marked by a striving for consensus and the smoothing out of conflicts in order to promote industrialisation and growth, the institutional model also supported the maintaining of mutual trust and loyalty between the employees and the employers.     

Long memory in the volatility of China stock returns

In this paper, we empirically examine the volatility process of China's stock market returns using daily and weekly Shanghai and Shenzhen stock indices during January 1990 to August 2008. To investigate the property of the process, we used the FIGARCH (fractionally integrated GARCH) model including GARCH and IGARCH processes as special cases. Since the FIGARCH model allows fractional integration order, it can detect hyperbolically decaying volatility processes which cannot be explained by previous models with integer integration order. Our results show that the Shanghai and Shenzhen stock indices exhibit long-term dependencies. The long memory properties of the Shanghai and Shenzhen stock markets do not seem to be spuriously induced without exception.     

工作记忆训练:研究现状及发展前景

工作记忆能够预测个体在认知加工任务中的表现,工作记忆容量具有相对稳定的特征,但近年来研究表明工作记忆容量可以通过训练得到改进。工作记忆训练直接影响额叶皮层、颅顶部皮层等大脑皮层活动以及中枢系统多巴胺受体浓度。工作记忆训练效应可以对未经过训练的工作记忆任务产生迁移,与工作记忆相关的神经网络亦能通过训练获得发展。工作记忆训练可以帮助个体减小因低工作记忆容量对学业成就、日常生活带来的影响。     

Additional Empirical Evidence on Real Convergence: A Fractionally Integrated Approach

We examine the real convergence hypothesis for 14 OECD countries looking at the fractional order of integration of the differences of real GDP per capita in these countries with respect to the United States. Using parametric procedures, the results vary depending on how we specify the I(0) disturbances. If they are white noise, convergence is achieved for Canada and Australia, and with autocorrelated disturbances, this hypothesis is satisfied for France and the Netherlands. However, allowing for a break at World War II, evidence of convergence is obtained for all countries. JEL no. C32, O41     

我国产业集群的竞争力研究

Industrial clusters have been an important phenomenon of the global economy. The most important reason for its becoming the focus of people＇s attention and the popular mode of industry programming is continuous and powerful competitiveness ,The article analyzes this competitiveness, and points out some problems of China＇s industrial clusters, which directly affects its current competitiveness and further development. Finally, we propose stone specific measures of those problems.     

Stochastic uncoupled dynamics and Nash equilibrium

In this paper we consider dynamic processes, in repeated games, that are subject to the natural informational restriction of uncoupledness. We study the almost sure convergence of play (the period-by-period behavior as well as the long-run frequency) to Nash equilibria of the one-shot stage game, and present a number of possibility and impossibility results. Basically, we show that if in addition to random experimentation some recall, or memory, is introduced, then successful search procedures that are uncoupled can be devised. In particular, to get almost sure convergence to pure Nash equilibria when these exist, it suffices to recall the last two periods of play.
