货币政策有效性研究的最新文献述评

本文从常见研究视角和常用研究方法两个角度,对货币政策有效性研究的最新文献展开综述。通过综述本文发现,参考最优货币政策规则理论的模型设定思路和量化方法,不仅可以避免以多元线性回归模型和S-VAR模型作为重要工具的相关研究中存在的诸如价格之谜和产出之谜等问题,而且其研究结论与政策建议更有利于宏观经济的长期稳定发展。     

开放经济下的货币政策独立性:一个理论框架——兼论货币区的“三元悖论”之解

美国次贷危机引发本轮全球性金融危机凸显了以美国为核心的金融资本主义模式和以美元为核心国际货币金融体系的制度性缺陷,改革现行以美元为核心的国际货币金融体系势在必行,建立货币区是较为现实的选择。但在现行货币政策框架下,货币区不可避免处于三元悖论困境。本文提出的贷款准备金政策框架模型能够解决货币区在保证其内在要求的资本自由流动和汇率稳定基本前提下,区内各个成员保持货币政策独立性问题。     

国际储备的演进与储备货币的价值分析

进入新世纪全球国际储备规模快速扩张,结构显著变化,进一步凸显了当代国际货币体系固有的体制性缺陷。研究表明,主导新世纪国际储备的主权信用货币实际上只有主权而没有信用。因此,当代国际储备体系必须改革,中国的国际储备也应该调整。     

东亚货币一体化的国际风险分担机制分析——基于第二代最优货币区理论的拓展

在经济全球化的背景下,区域货币一体化对于区域内各国的经济发展有着重要意义。当前的国际金融危机使东亚地区货币合作又重新进入人们的视野,关于东亚货币一体化的可行性分析也进入了一个崭新的阶段。此时,我们更需要从抵御风险,实现共同发展的角度来探讨东亚货币一体化。中国作为东亚区域内有影响力的大国,应对此问题有深入思考。本文对最优货币区理论进行了有益的拓展,建立了基于微观基础的国际风险分担机制模型,并运用动态优化的方法严格证明了货币一体化所形成的国际风险分担机制使成员方达到消费保险的目的,这为进一步推动东亚货币一体化的建设提供了新的理论依据。     

Financial dollarization: Short-run determinants in transition economies

This paper examines the determinants of financial dollarization in transition economies from a short-run perspective. Using aggregate monthly data of deposit and loan dollarization we study the drivers of short-term fluctuations in dollarization and test their importance at different levels of dollarization. The results provide evidence that (a) the positive (negative) short-run effects of depreciation (monetary expansion) on deposit dollarization are exacerbated in high-dollarization countries; (b) short-run loan dollarization is mainly driven by banks matching of domestic loans and deposits, currency matching of assets and liabilities, international financial integration, and institutional quality; and (c) both types of short-run dollarization are affected by interest rate differentials and deviations from desired dollarization.     

Central bank interventions and implied exchange rate correlations

This paper examines the effects of the foreign exchange market interventions by the Bank of Japan on the ex ante correlations between the JPY/USD, EUR/USD, and GBP/USD exchange rates. The correlation estimates used in the analysis are derived from the market prices of OTC currency options. The results show that central bank interventions significantly affect the market expectations about future exchange rate co-movements. In particular, we find that interventions tend to temporarily increase the ex ante correlations among the major exchange rates. However, our results also suggest that intervention episodes are associated with lower-than-average levels of exchange rate correlations.

On the cost of delayed currency fixing announcements

In Foreign Exchange Markets vanilla and barrier options are traded frequently. The market standard is a cutoff time of 10:00 a.m. in New York for the strike of vanillas and a knock-out event based on a continuously observed barrier in the inter bank market. However, many clients, particularly from Italy, prefer the cutoff and knock-out event to be based on the fixing published by the European Central Bank on the Reuters Page ECB37. These barrier options are called discretely monitored barrier options. While these options can be priced in several models by various techniques, the ECB source of the fixing causes two problems. First of all, it is not tradable, and secondly it is published with a delay of about 10–20 min. We examine here the effect of these problems on the hedge of those options and consequently suggest a cost based on the additional uncertainty encountered.
