国际贸易模型中的汇率变量研究

随着汇率波动的加剧,汇率对贸易的影响凸现.古典与新古典主义因所处于固定汇率体制中的金本位时期,所以并未给以汇率以足够的重视;凯恩斯主义在其需求分析的框架中研究汇率,因此其汇率分析也必然带有凯恩斯主义固有的缺陷--缺乏较坚实的微观基础;新国际贸易理论在产业内贸易框架中分析汇率变量.缺乏宏观高度.本文基于浮动汇率前提,试在宏观经济层面寻找国际贸易中汇率变量的微观基础,并给出程式化分析.     

汇兑损益对上市公司利润影响的理论和实证分析

从2005年7月21日汇改后,人民币汇率的波动远大于汇改之前,由此给企业形成的汇兑损益将会更加不稳定。在此背景下,本文通过研究上市公司重点行业近几年汇兑损益的变化,并就汇兑损益对企业财务费用和利润影响进行了实证分析,得出汇兑损益和企业利润存在正相关关系,在此基础上,提出了企业控制外汇风险、减少汇兑损失的相关措施。     

Causality and volatility patterns between gold prices and exchange rates

This paper provides a new perspective on the link between gold prices and exchange rates. Based on gold prices denominated in five different currencies and the related bilateral exchange rates, we put causalities and short-run volatility transmission under closer scrutiny. We provide evidence that the identification of a strong hedge function of gold requires an explicit modeling of the volatility component. For all currencies, exchange rate depreciations initially have a negative impact on the gold price after one day which turns out to be positive after two days in most of the cases. Contrary to previous studies, our results point to a specific role of the dollar in the context of gold-exchange rate relationships: volatility of dollar exchange rates more frequently results in strong hedging functions of gold prices. Furthermore, the gold price denominated in the US dollar tends to increase after a depreciation of the dollar.     

The timing of exchange rate collapse

Recent episodes of exchange rate collapse have renewed interest in models of speculative attacks. These episodes have been considered by some observers to be inconsistent with “fundamentals” models of attack since there was no prolonged period of policy misalignment and declining reserves, as required by such models. This paper develops a fundamentals model in which collapse is instantaneous at the time of unexpected policy change and/or a change in the expectations of future policy, even for a reserve abundant country.     

我国货币政策传导机制有效性研究:条件与结论

对几种货币政策传导机制的利用是否有效,取决于市场失衡的程度与开放的程度以及经济发展不同时期的机遇。目前我国新兴市场资金流动与各市场间的联系主要受资产价格传导机制作用的引导,而不是利率传导。人民币升值带来的机遇并非仅发生在商品市场,更发生在资本市场,汇率传导机制的作用虽然影响了出口,但是目前却更有利于资本输出下的海外收购与兼并,从而降低了通货膨胀传递下商品市场的投资成本。     

Corporate governance and incidences of listing suspension by the JSE Securities Exchange of South Africa: An empirical analysis

We examine the association between corporate governance structures and incidences of listing suspension from the JSE Securities Exchange of South Africa. Using a matched-pairs research design, we compare 81 firms suspended between 1999 and 2005 to an equal number of control firms matched in terms of time, size and industry. Employing a conditional logistic model, we find that the likelihood of suspension is higher in firms with a smaller proportion of non-executive directors, without an audit committee, and with greater block-share ownership and higher gearing (i.e. leverage). Further analysis splitting block-share ownership into institutional and non-institutional investors provides mixed results. While we find a positive association between suspension and non-institutional investors, we observe no association with institutional investors. No association is detected for board size, role duality, directors' share ownership, auditor quality and return on assets. Given the paucity of studies examining listing suspension from stock exchanges and corporate governance mechanisms, these findings contribute to the literature. Additionally, the dearth of research on corporate governance in developing countries suggests that our findings have important implications for policy makers in these countries as they endeavor to improve corporate governance.     

新兴市场经济国家通货膨胀与汇率制度选择

本文利用23个新兴市场经济国家20年间的面板数据,对汇率制度和通货膨胀的关系进行实证研究,对我国汇率改革实践进行了考察。从我国的实际情况看,汇率波动的幅度越大则通胀率均值越大,2005年实行管理浮动以来我国通胀率处于明显的上升趋势。我国应该限制人民币升值幅度,发挥汇率的"名义驻锚"的作用,以此遏制通胀的进一步发展。     

Japanese FDI into U.S. service industries: Exchange rate changes and services tradability

Using the implications of the model of investment under uncertainty, this paper provides a systematic examination of the FDI–exchange rate relationship with respect to services taking into account the degree of tradability across services. Services have mainly been addressed in the literature as a sensitivity test by industry using aggregated service data identified as “nonmanufacturing”. Using data on Japanese FDI into 207 U.S. service industries, maximium-likehood estimates reveal that dollar appreciations are positively correlated with service FDI flows into the U.S. This positive correlation is stronger for non-tradable services versus tradable services. For tradable and non-tradable producer services, higher exchange rate uncertainty may lead to fewer FDI occurrences. On average, across all types of services, higher U.S. unit labor costs relative to Japan had a deterrent effect on Japanese service FDI as well. Finally, this paper also provides a useful benchmark to partition services by tradability.

论实现法治的最基本条件

市场经济是一种法治经济，所有权与债权都必须在保持合法主体的前提下，通过等价交换的原则来得以充分实现，因此我们必须加强社会主义市场经济的法治建设。
