论本币升值对国内物价的影响路径

本币升值可通过实体经济、虚拟经济以及货币政策三个途径影响一国的国内价格;本币升值通过国内物价影响经济稳定存在一个正反馈机制;从短期来看,人民币升值不仅不能抑制国内物价上涨,还可能推动国内物价的上涨。     

The impacts of Hong Kong’s Currency Board reforms on the interbank market

Among the economies with a Currency Board System (CBS), Hong Kong (HK) is probably the one with the largest and most developed financial sector, as well as the highest capital mobility. Hence, studying HK’s CBS is not only crucial to HK, but also important for the understanding of the modern CBS. This paper outlines the major monetary reforms in HK since the late 1980s. The impacts of these reforms and the 1997–1998 Asian Financial Crisis are then examined empirically. We focus on the differentials between the US and HK interbank interest rates. We assume the conditional-mean equation follows an autoregressive process and the conditional-variance equation follows a generalized autoregressive conditional heteroscedasticity process. This model captures the time-varying level and volatility of the differential. In light of the empirical results we provide an assessment of the reforms in HK.     

哥伦布发现美洲的动因和影响

哥伦布发现美洲是世界史上的划时代大事 ,使世界历史发生了历史性的变化 ,是人类历史的一个重大转折点。它打破了世界各民族的原始封闭隔离状态 ,扩大了世界各民族间相互影响活动范围 ,从而使世界历史开始形成。本文就哥伦布发现美洲的动因和所产生的影响做一些肤浅的论述。     

The relevance of currency risk in the EMU

We investigate how the elimination of intra-European exchange risk may affect international financial markets using a conditional version of the International CAPM. We estimate the EMU and non-EMU components of aggregate currency risk and document significant exposures to both. The premium for EMU risk is positive and associated with exposure to the French, Italian and Spanish currencies. The premium for non-EMU risk is consistently negative and accounts for most of the aggregate currency premiums. In the 1990s, exposures to EMU risk declined significantly while exposures to non-EMU risk increased. Hence the adoption of the Euro is unlikely to have a large impact on aggregate currency risk premiums.     

对EWS模型中金融危机界定的比较研究 ——利用EVT理论

对主要金融危机预警模型中货币危机指标(货币压力指数)与阈值的确定方式进行比较分析,之后利用EVT对EMPI的尾部进行估计,同时确定新的个体阈值,并与原模型的结果进行对比。发现不同的EW S模型确定的危机时间有较大差异,各种方法在危机的判断上存在分歧;三种主要EW S模型中的EMPI在统计上表现出较强的非正态性。     

银行危机与货币危机共生性关系的实证研究

1 997— 1 998年的亚洲金融风暴中 ,银行危机与货币危机的同时爆发 ,即共生性危机的发生引发国际社会与学术界对这种现象的重新思考 :这种共生性现象是否确实具有普遍性 ?从理论的角度来看 ,银行危机与货币危机之间的确存在着一定的联系 ,但到目前为止 ,很少有研究从实证的角度来证明这种联系的确存在。正是基于此 ,本文从实证的角度出发 ,旨在揭示出银行危机与货币危机之间的确存在着相互影响 ,换言之 ,共生性危机的发生是具有显著性的。具体来说 ,本文以 1 975— 2 0 0 0年期间 53个国家危机的发生情况为研究对象 ,分别运用频率分布、信号法 ,以及概率回归模型来分析两种危机的共生性 ,并得到非常一致的结论 :在新兴市场国家中 ,银行危机与货币危机之间的确存在着明显的相互关系 ,同时银行危机更趋向于作为货币危机即将发生的同步或预警指标 ,而反之则不然。     

世界经济失衡背景中的人民币汇率制度改革

人民币升值的真正原因在于,从对外经济往来层面上来看,美国在贸易逆差扩大背景下对中国愈演愈烈的人民币升值的"攻势";从国内宏观经济层面来看,"外汇占款"带来流动性过剩压力。宏观经济的客观因素以及中国政府的主观因素决定了人民币汇率升值过程只能是渐进的,而不是一步到位的,尽管渐进策略会进一步强化人民币升值的预期。对不同经济主体而言,人民币升值的利益效应不同,因此很难简单概括其总体效应。近期来看,人民币汇率升幅已经达到了一定的水平,与人民币升值相关的越来越强烈的负面效应以及金融突发事件效应,应该引起政府的密切关注。     

基于双基准与多风险制度下的中国外汇储备币种结构配置研究

内容借鉴Markowitz基本均值方差模型的思想,本文运用基于双投资基准和多风险制度的投资组合模型对我国外汇储备币种结构配置进行了实证研究。本文首先从中国实际出发确定了两个投资基准和三种风险制度,进而在此基础上实证研究了在不同投资基准、不同风险制度和不同风险厌恶度情况下的我国外汇储备币种结构。最后,本文提出在不同风险制度转换过程中所对应的我国外汇储备各币种所占比重的调整方向。     

Carry trade strategies based on option-implied information: Evidence from a cross-section of funding currencies

We document carry trade returns based on the moments extracted from options on the underlying currencies. We establish three important results. First, a currency pair is predicted to have greater excess returns if option-implied returns are more volatile, are more left-skewed, and have fatter tails than the returns of other currency pairs. Second, strategies based on option-implied information improve on benchmark strategies based on realized market returns and macroeconomic data. Third, if the option-implied returns of a currency pair are more left-skewed than in the past, anti-carry trades rather than carry trades perform better.     

Examining dynamic currency linkages amongst South Asian economies: An empirical study

In this paper, we examine the currency market linkages of South Asian member countries using daily data from 6 January 2004 to 31st March 2016. Time invariant and varying Copula GARCH models show that South Asian countries, except for India and Nepal/Bhutan, have low levels of currency market linkages which can be ascribed to poor levels of intra-regional trade intensity and portfolio flows. We reconfirm the copula results through Diebold and Yilmaz methodology and document that currency market connectedness is very limited in the South Asian region. The trends of the fundamental determinants of currency co-movements for the South Asian member countries were compared with its neighbouring regional economic bloc in Asia which has a much longer history and a wider membership base i.e ASEAN + 6. From a comparative analysis, it was found that South Asia member states have to work on their governance parameters, improve on their trade linkages and trade tariffs and work towards greater degree of capital account convertibility with adequate safeguards to achieve higher levels of currency market linkages.
