国际收支与金融市场效率问题的探讨

以“逆差 顺差”为特点的美国国际收支结构是很难长期持续的,美国经常项目很可能会经历趋向平衡的调整过程。由于中美两国国际收支结构存在较强的互补性,美国国际收支结构的调整对目前中国国际收支结构提出了严峻挑战。金融市场的行政分割、金融资源结构及流向的不合理是影响中国国际收支结构失衡的重要因素,因此中国应该完善和发展金融市场,积极主动地调整目前失衡的国际收支结构以应对美国国际收支结构调整可能给中国经济发展带来的不利影响。     

外汇储备、外汇交易量与CHIBOR利率的VAR模型(2000～2004)——兼论“三元悖论”下冲销干预与货币政策的独立性

本文以“三元悖论”为切入点,从总量与结构两方面考察当前结售汇制度对商业银行外汇头寸及外汇交易量的影响,进而考察在货币政策时滞的影响下央行冲销干预的效果以及货币政策的独立性。结论认为:我国外汇储备成因中政策性制度安排(结售汇)作用突出,现行结售汇业务导致外汇交易量受到外汇储备的冲击,冲销干预的有效性十分有限且不确定性很强。在CHIBOR利率的波动中,外汇储备和外汇交易量的作用不可忽视,同时外汇交易量的波动中,外汇储备与CHIBOR利率的冲击作用贡献明显,货币政策独立性受到侵蚀。     

美国证券法对衍生交易市场风险披露的监管及借鉴——以SEC“305规则”体制的监管要求为视角

在以市场风险披露为基础的衍生交易监管政策下,SEC的“305规则”体制由定量、定性信息披露要求与前瞻性信息披露的安全港规则有机构成。我国应当借鉴先进的风险监管规则,构建创新的衍生工具市场风险披露法律框架,并解决好创新规则实施过程中的成本-收益权衡问题、收益波动性问题。     

The Informational Efficiency of the Equity Market As Compared to the Syndicated Bank Loan Market

The loan market is a hybrid between a public and a private market, comprised of financial institutions with access to private information about borrowing firms. We test whether this is reflected in informationally efficient price formation in the loan market vis-a-vis the equity markets, and reject this private information hypothesis. We also reject a liquidity hypothesis which suggests that equity markets always lead loan markets, despite bank lenders' access to private information, because of greater liquidity in equity markets. We further test, and reject, an asymmetric price reaction hypothesis that states that loan returns are more sensitive to negative information whereas equity returns respond symmetrically to both positive and negative information. We find evidence most consistent with an integrated markets hypothesis that suggests that both the equity and syndicated bank loan markets are highly integrated such that information flows freely across markets. This is particularly true when the equity market makers are also loan syndicate members.

我国基金选股选时能力实证分析

本文运用西方基金绩效评价中较为常见的选股选时能力模型及其FF3改进模型对我国证券投资基金进行实证研究,在处理过程中考虑了不同取样频率和不同样本区间的影响.研究结果表明:(1)我国基金只存在很小程度的选股能力,而基本不存在选时能力,更没有基金同时具有选时能力和选股能力;(2)多因素改进模型与原模型相比显著提高了解释能力,说明在可能的情况下应尽可能使用多因素模型;(3)加快取样频率后基金表现出更强一些的选股能力,但在各年度内基金的选股能力有所差异.     

Market orientation and customer satisfaction: Evidence from British machine tool industry

This paper examines empirically the relationship between market orientation and business performance in the context of British machine tool industry. An industry-specific market orientation scale was developed. Factor analysis revealed that there were four latent dimensions underlying the market orientation: customer orientation, competitor orientation, departmental responsiveness, and customer satisfaction orientation. Findings suggest that customer orientation and customer satisfaction orientation have a stronger impact on performance than the other dimensions, and that competitor orientation has a U-shape relationship with performance. Departmental responsiveness did not appear to be significantly related to the business performance. Managers could use the multidimensional conceptualization to develop particular kinds of orientations required for better performance.     

Two Views of Accounting Measurement

The two views to be addressed here are the Chambers/Sydney view that accepts only one measurement method—current net realizable price—and the Staubus/mainstream view that accepts several measurement methods in the same financial report. These two views became well-established in the literature of accounting in the 1960s and their proponents have clung tenaciously to their oft-criticized positions for some forty years. However commendable their original expositions may have been, their continuing existence does no credit to the small coterie of accountants now interested in theory.
This article is aimed at 'narrowing the areas of difference' between adherents to the two views by isolating fundamental bases for them and exposing the reasoning supporting their structures. In a nutshell, they differ in their objectives and they can be expected to survive unless their adherents agree on the objectives of financial reporting.     

Scientific methods in finance

Computer software can easily produce many financial models with technical skill, but investigators need to interpret and adapt computer output. Such analysis requires a deep knowledge of scientific fundamentals. We argue that an evidential perspective is more appropriate than a decision framework for model selection. We discuss four necessary conditions for any scientific investigation: observables, interpretables, replicables, and robustness in the context of examples familiar to finance professionals. Carefully planning the design of an experiment is the best way to address many econometric maladies. Furthermore, we emphasize the need for more sensitivity testing and for independent replication of empirical results within the finance profession.     

On the source of contrarian and momentum strategies in the Italian equity market

This paper investigates the source of momentum profits, while inferring the validity of the assumptions underlying rational and behavioural theories. Using a unique sample of securities listed in the Italian Stock Exchange from 1950 to 1995, we observe that buying better performing stocks in the previous 3-12 months and selling worse performing stocks over the same period yields significant profits in the short term (less than 1 year). Results also hold when conditioned upon different risk specifications. On the other hand, the continuation effect seems to significantly revert over a longer period. More importantly, in contrast with Conrad and Kaul [Rev. Financ. Stud. 11 (1998) 489], bootstrap and Monte Carlo simulations show that momentum profits are more likely to be generated by stock returns time series properties rather than by their cross-sectional differences. While the overall findings cannot reject the market efficiency hypothesis, we argue that behavioural theory may be a possible “story” to interpret the continuation effect.
