基于真实收益率的中国外汇储备最优币种结构分析

本文利用Markowitz提出的资产组合理论(Markowitz,1952),结合中国外汇储备结构的具体情况,根据经济实力、币值稳定性和交易匹配三大原则,摒弃含有诸多弊端的、单纯以美元计价的外汇储备收益率,改为采用以商品篮子衡量的外汇储备真实收益率作为期望收益率,利用二次规划工具求出了以4种外汇储备最优资产组合的风险有效前沿,测算出我国外汇储备最优币种结构,并给出相应建议,以期实现外汇储备保值增值的目标。     

货币危机的政治经济学解释:文献评述

作者从文献的角度对货币危机的政治经济学解释做了一次比较全面的梳理,从中可以看出国际金融政治经济学的研究特点和思维方式。在理论构建上,政治经济学的学者们完全沿用了经济学模型中的不完全信息和动态博弈论,引入了预期的形成以及市场交易者和政府之间的战略互动,从而成功地把各种政治和经济变量纳入到一个模型之内。他们的贡献是,把政治变量引入到市场交易者和政府的预期形成中,强调了政治变量以及作为一种信息的政治变量在市场交易者和政府预期中的作用或者地位,并强调了政治变量在市场交易者和政府之间战略互动或动态博弈过程中的作用,从而更好地解释了货币危机的原因,提高了预测货币危机的准确性。在实证研究上,政治经济学通过预期效用函数、战略概率模型等方式,较为成功地实现了对政治因素这个分类变量的模型化,较好地实现了对政治因素的量化分析。     

物价稳定、货币流通速度与宏观调控愿景把握

对欧美国家和我国曾经发生的货币流通速度陡升型通胀和货币流通速度陡降型通缩进行实证分析表明,现阶段我国货币流通速度似处于一个非渐变、非常规的特殊时期,相关不确定性因素一旦演变为确定性的组合,很可能产生经济运行中的某种临界转换点,并可能对我国货币政策和宏观政策调控带来挑战。应加强对货币流通速度的监测和对货币需求变化的研究预测,进而优化市场预期管理和宏观应急管理,提高应对货币流通速度突变型通胀、通缩的能力,以更好地追求与维护物价稳定和提高宏观调控水平。     

Renminbi Internationalization： Progress, Prospect and Comparison

Using principal component analyses, this paper constructs two internationalization indices for the renminbi (RMB) and 32 other major currencies. We find that the RMB's currency internationalization degree index (CIDI) is still low, and far behind the 4 most important international currencies. In 2009, it was ranked 18th among all important international currencies. However, in terms of the currency internationalization prospect index (CIPI), the RMB has remained the world's fifth highest since 2006. Although it is still far behind the US dollar and the euro, surpassing the ranking of the yen and the pound is possible in the near future. The dramatic difference in the ranking between the CIDI and the CIPI is a result of China's tight capital account control, the usage continuity of international currency due to network externalities, and the narrow foreign exchange and imperfect financial markets. Hence, to a large degree, the RMB's potential as an international currency depends on China's capital account liberalization.     

Exchange Rate Crises and Fiscal Solvency

This paper combines insights from generation one currency crisis models and the fiscal theory of the price level (FTPL) to create a dynamic FTPL model of currency crises. The initial fixed‐exchange‐rate policy entails risks due to an upper bound on government debt and stochastic surplus shocks. Agents refuse to lend into a position for which the value of debt exceeds the present value of expected future surpluses. Policy switching, usually combined with currency depreciation, restores fiscal solvency and lending. This model can explain a wide variety of crises, including those involving sovereign default. We illustrate by explaining the crisis in Argentina (2001).     

Mexican Peso Futures and Exchange Rate Volatility

Abstract

The reintroduction of Mexican peso futures contracts in April 1995 resulted from a refocus of governmental policy to the use of market-based mechanisms to stabilize the exchange rate. Interest in the Mexican peso future contracts has been high as investors look to manage their exposure from transactions and investments denominated in pesos. This study utilizes a VAR framework to analyze the relationship between the volatility in the Mexican peso spot market and futures contracts trading activity. Shocks to the exchange rate volatility lead to increased hedg-ing-type activity. Furthermore, an increase in futures contracts trading activity (reflecting additional speculation-type activity) results in a short-run increase in volatility. A Granger Causality test also indicates a statistically significant link between spot price volatility and futures trading activity in the Mexican peso exchange market.

RESUMEN

La reintroducción de los contratos futuros del peso mexicano en abril de 1995, resultó del nuevo enfoque de la política gubernamental de usar los mecanismos de mercado para estabilizar la tasa cambiaria. Ha habido mucho interés en los contratos futuros del peso mexicano, ya que los inversores buscan administrar su exposición a las transacciones e inversiones denominadas en pesos. Este estudio utiliza el marco del VAR para analizar la relación existente entre la volatilidad del peso mexicano en el mercado spot y la actividad de negociación de los contratos futuros. Los choques sufridos por la volatilidad de la tasa cambiaria resultan en un aumento de las actividades del tipo hedging. Además, un aumento en la actividad de negociación de los contratos futuros (que refleja otras actividades de naturaleza especulativa) provoca, a corto plazo, un aumento en la volatilidad. Una prueba Granger Causality también indica un vínculo estadísticamente significativo entre la volatilidad del precio spot y la actividad de negociación del mercado futuro en el mercado cambiario del peso mexicano.

RESUMO

A reintrodução dos contratos futuros em peso mexicano, em abril de 1995, foi o resultado de uma revisão da política governamental, em relação ao uso dos mecanismos baseados no mercado para estabilizar a taxa de câmbio. Os juros dos contratos futuros, em peso mexicano, foram altos, devido ao cuidado dos investidores em administrar o risco das transaç[otilde]es e dos investimentos efetuados em pesos. Este estudo utiliza a estrutura VAR, para analisar o relacionamento entre a volatilidade do mercado local, em peso mexicano, e a atividade comercial de contratos futuros. Choques aplicados à volatilidade da taxa de câmbio contribuíram para o aumento das atividades típicas de hedging. Além disso, um crescimento da atividade comercial de contratos futuros (refletindo uma atividade basicamente especulativa) ocasiona um rápido aumento na volatilidade. O teste Granger Causality indica, também, um vínculo estatístico significativo entre a volatilidade do preço local e a atividade comercial de futuros no mercado cambial do peso mexicano.     

Revisiting the theory of optimum currency areas: Is the CFA franc zone sustainable?

This paper aims at explaining why the CFA countries have successfully maintained a currency union for several decades, despite failing to meet many of optimum currency area criteria. We suggest that the CFA zone, while not optimal, has been at least sustainable. We test this sustainability hypothesis by relying on the Behavioral Equilibrium Exchange Rate (BEER) approach. In particular, we assess and compare the convergence process of real exchange rates towards equilibrium for the CFA zone countries and a sample of other sub-Saharan African (SSA) countries. Our findings evidence that internal and external balances have been fostered and adjustments facilitated in the CFA zone as a whole—compared to other SSA countries—as well as in each of its member countries.     

人民币区域化货币动因研究进展——基于CAFTA的实证研究

随着中国—东盟自由贸易区的顺利落成,意味着我国与东盟的经贸往来将变得更加密切,而人民币在东南亚的流通和使用就必然面临着人民币区域化。人民币区域化理论研究的突破应和如何把握CAFTA这个平台结合起来。本文通过综述相关文献来厘清人民币区域化的货币动因,并通过相关实证研究阐释CAFTA这个贸易平台对与人民币区域化顺利实施的重要意义。     

补充货币、社区货币及其试运行路径

通过对克鲁格曼、列特尔和党爱民等学者的研究文献解读，有了补充货币及其社区货币中国试运行的四种选择路径：公益互助性的城市社区货币所昭示的时间经济具有旺盛的生命力；在农村流行的道义性“社区货币”中硬塞进一个信用券证无助于扶贫济困；以名目繁多的消费券为主要标志的社会分红试验显示出全民分红逐渐推广的重要迹象；对网络虚拟货币突破货币发行政府垄断之“门”的小小缺口，宜疏不宜堵。
