WTO与中国金融业的发展

入世给我国金融业既带来了机遇，也带来了挑战。面对新形势，我国金融业要有新的发展思路：放宽金融兼并重组的限制，逐步取消分业经营制，大力发展和完善金融中介机构和中小企业融资担保机制，鼓励金融创新，增强银行的盈利能力。     

Non‐Parametric Modelling of CO2 Emission Quota

Dutch glasshouse firms are facing the introduction of a system of tradable CO₂ emission quotas. This paper employs a non‐parametric method for modelling tradable CO₂ emissions of Dutch glasshouse firms. The method is capable of generating shifts in CO₂ emissions across the sample of firms. Moreover, changes in volumes of outputs produced and inputs used are computed. Results show that firms using a conventional heating technology will be net purchasers of CO₂ emissions, whereas firms using more advanced heating technologies will sell part of their emission quota.     

The relational benefits of personalized communications in an online environment

This research investigates how personalized communications enhance customer‐company relationships, which ultimately produce favourable marketing outcomes. Two factors were manipulated in an online experiment: the perceived effort made by customers to obtain a personalized newsletter (high vs. low) and the level of relevance of the message (high vs. low). The results indicate that perceived effort positively affects calculative commitment (even more so for highly involved customers), while the level of relevance of the message increases affective commitment. In addition, the interaction between perceived effort and message relevance has significant effects on calculative and affective commitment. Finally, affective commitment partially mediates the relationships between relevance and both loyalty and word‐of‐mouth intentions. Managerial implications regarding the best usage of personalized communications are discussed. Copyright © 2013 ASAC. Published by John Wiley & Sons, Ltd.     

Habit Formation in an Overlapping Generations Model with Borrowing Constraints

We introduce habit‐formation in the three‐period OLG borrowing‐constrained framework of Constantinides et al. (2002) by allowing the utility of the middle‐aged (old) to depend on consumption when young (middle‐aged). This specification enables us to separate the effect of the two habit parameters (middle‐aged and old) since each representative age‐group can face different levels of habit persistence. The two‐habit setup underlines some important issues with regards to savings and security returns which do not always conform to the standard findings in the literature. In addition, the model produces equity premium consistent with US data for relatively small levels of risk aversion.     

On the finite sample behavior of testing whether new is better than used of a specified age

Hollander, Park and Proschan (1986) proposed a test of new is better than used of a specified age. It is based on large sample normality of the test statistic. There is, however, no study in the literature on its actual size for small and moderate sample sizes. To shed some lights on this, the results of a Monte Carlo simulation study as well as two real data examples are reported and these indicate that the test can have a quite liberal size, especially for small to moderate sample sizes. In order to improve on this weakness, a modified test is proposed and studied. It is noticed that this modified test seems to over-correct the original test to an extent that it becomes unduly conservative sometimes. Hence we propose another modification that combines the original test and the modified test turns out to have its size quite close to the nominal level and is therefore preferable to both the original and modified tests.

A Note on the Joint Distribution of α, β-Percentiles and Its Application to the Option Pricing

In this paper, using Laplace transform, we will calculate the joint density of twopercentiles of stock prices in the Black013;Sholes model and make the price of exchange options of such twopercentiles.
