多指标综合评价方法的优选

文章认为综合评价方法的合理性取决于运用该方法对被评对象进行等级排序的合理性。据此,在建立了合理等级排序依据的前提下,可以根据各综合评价方法所做的等级排序与合理等级排序的"差距"或"相关度"来进行综合评价方法的优选。

How do great shocks influence the correlation between oil and international stock markets?

We investigate the impacts of great shocks (2003 Iraq War and 2008 Financial Crisis) on the correlations between oil and US/China stock markets, utilizing a novel MADCC (mixed asymmetry dynamic conditional correlation) model. This model successfully captures the coexistence of opposite signed asymmetries. We find that great shocks indeed increased the correlations. Further, results from the news impact surfaces indicate that correlations between oil and stock markets are higher to joint negative shocks; however, correlation between stock markets has stronger response to joint positive shocks.     

The correlation coefficient and problems of inference in recreation research

Correlation analysis frequently has been used for the investigation of leisure research questions. This paper illustrates the problem of “unequal weighting of cases” which is present in the use of correlation analysis. It further illustrates how this problem can mislead researchers when they make substantive inferences about leisure.     

Analysis on Balance Gap between Saving and Credit Account in China

In China, the balance gap of credit and saving account emerged in 1995, and its amount enlarged since then. By the end of Dec. 2005, with 28.7 trillion RMB saving balance and 19.5 trillion RMB gross credit account balance, the gap between saving and credit account was as large as 9.2 trillion RMB, which indicated a 67.8% of credit/saving ratio. Some believed this phenomenon was resulted from on one hand, the rapid growth of saving account; and on the other hand, relatively slower expanding of credit account. Some believed cooling down cash demand was behind the gap, while others claimed the balance gap caused dead capital and inefficiency service of saving account. In fact, the balance gap between credit and saving account might not necessarily relate to dead bank capital. And the phenomenon itself could not indicate the down-tendency of finance power that underlay economy. Nevertheless, it was liquidity not the balance gap should be regarded an index of capital situation in financial organizations. Therefore the balance gap between saving account and credit account could not be viewed as criteria against liquidity position. Solution of this problem should lay in boosting financial innovation among commercial banks, expending capital market and encouraging or permitting commercial banks as well as state-owed funds to enter share market and so on.

Developing Countries and Environmental Protection: Contract Design in Perfectly Correlated Environments

I study the problem faced by an asymmetrically informed supranational governmental authority (SNGA) with limited funds that wishes to design an international environmental agreement (IEA) for less developed countries (LDCs). The SNGA cannot contract directly with polluting firms in the various LDCs, but it must deal with such firms through their national governments. I study this tripartite hierarchical interaction for two LDCs. My principal result is that despite the perfect correlation in the private information of the governments and the firms across the two countries, and in contrast with the result contained in Batabyal (1998a), the SNGA cannot implement a first-best IEA.     

CB – Time Dependent Markov Model for Pricing Convertible Bonds

In this paper, we propose what we call the convertible bond (CB) – timedependent Markov model, which prices N given individual convertible bondssimultaneously, and apply it to Japanese convertible bond data. One of themain features of the model is that it makes full use of the correlationstructure of convertible bond prices. The empirical results show that themodel well describes individual prices in the market.
