中国外汇储备增长的因素分析与对策探讨

中国外汇储备已突破2万亿美元大关,人民币汇率的低估被认为是外汇储备快速增长的主要原因。通过实证分析发现,中国外汇储备的增长受到贸易条件、相对技术进步和外商直接的投资等因素变量的影响,人民币实际汇率对外汇储备增长的影响并不显著,通过人民币实际汇率大幅升值来调整外汇储备增长的做法是不可取的。当前应该采取措施促进非贸易部门的技术进步,适当增加进口,优化外资引进政策以减缓外汇储备的快速增长。     

发展中国家和地区汇率制度变革及其对中国的启示

本文介绍和分析了一些发展中国家和地区的汇率制度变革的经验和教训以及对中国人民币汇率制度改革可供参考的思路，这些启示将是重要和有价值的。     

对我国外汇储备问题的若干思考

我国国际收支的连年顺差,境外热钱不断流入,人民币升值压力的进一步增大,再加上我国长期实行的外汇制度等原因,使我国外汇储备大幅增加,而且已经是过量增长.而过多的外汇储备量,会给我国带来一定的风险和损失,包括通货膨胀带来的损失、美元贬值带来的损失以及存在的机会成本等.因此,要从控制增量、合理使用和配置资产以及改革现行外汇制度等角度出发,对我国外汇储备进行合理的控制.     

人民币汇率与外商直接投资关系研究——基于上海市的数据

运用Johansen协整检验、Granger因果检验、脉冲响应分析等实证方法研究上海市外商直接投资与人民币实际有效汇率及其波动之间的相关性,研究表明:上海市外商直接投资(FDI)与实际有效汇率(REER)、地区国内生产总值(GDP)和对外依存度(OPEN)显著正相关,与汇率波动(VOL)和平均工资(WAGE)显著负相关;短期内人民币实际有效汇率及其波动对上海市外商直接投资存在影响,且汇率的波动比其实际值的大小更能影响外商直接投资;实际有效汇率及其波动的冲击在零期对外商直接投资均没有影响,响应值在第四期达到最大,实际有效汇率对于外商直接投资的影响主要体现在投资时机的选择上。     

The real exchange rate and economic growth: are developing countries different?

Recent research has found a positive relationship between real exchange rate (RER) undervaluation and economic growth. Different rationales for this association have been offered, but they all imply that the mechanisms involved should be stronger in developing countries. Rodrik (2008 Rodrik, D. 2008. The real exchange rate and economic growth. Brookings Papers on Economic Activity, 2: 365–412.  [Google Scholar]) explicitly analyzed and found evidence that the RER–growth relationship is more prevalent in developing countries. We show that his finding is sensitive to the criterion used to divide the sample between developed and developing countries. Using alternative classification criteria and empirical strategies to evaluate the existence of asymmetries between groups of countries, we find that the effect of currency undervaluation on growth is indeed larger and more robust for developing economies. However, the relationship between RER undervaluation and per capita GDP is non-monotonic, and is limited largely to the least developed and richest countries. This discontinuity constitutes a puzzle that calls for closer analysis.     

Theorizing the Financial Statecraft of Emerging Powers

‘Financial statecraft’, or the intentional use of credit, investment and currency levers by the incumbent governments of creditor – and sometimes debtor – states for both international economic and political advantage, has a long history, ranging from money doctors to currency wars. A neorealist, zero-sum framing of international monetary relations is not inevitable, yet casts a persistent shadow especially during periods of prospective interstate power transitions when previously peripheral countries find themselves with unexpected new capabilities. This article seeks to understand and theorise the financial statecraft of emerging economies, moving beyond the traditional understanding that closely identifies the concept with financial sanctions imposed by a strong state on a weaker state. We propose that the aims of financial statecraft may be either ‘defensive' or ‘offensive’. Financial statecraft may be targeted either ‘bilaterally' or ‘systemically’. Finally such statecraft may employ instruments that are either ‘financial' or ‘monetary’. As emerging market economies have moved up in the ranks in the interstate distribution of capabilities, they have also expanded their financial statecraft strategies from narrowly defensive and bilateral to those involving offensive tactics and targeted at the global and systemic level. Historical and contemporary examples illustrate the analysis.     

The effects of foreign direct investment on domestic firms

This paper uses firm‐level panel data to investigate empirically the effects of foreign direct investment on the productivity performance of domestic firms in three emerging economies of Central and Eastern Europe: Bulgaria, Romania and Poland. To this end, a unique firm‐level panel dataset is used with detailed information on foreign ownership at the firm level. Two main questions are addressed in the present paper: (1) do foreign firms perform better than their domestic counterparts? (2) do foreign firms generate spillovers to domestic firms? The estimation technique in this paper takes potential endogeneity of ownership, spillovers and other factors into account by estimating a fixed effects model using instrumental variables in the general methods of moment technique for panel data. Only in Poland, do foreign firms perform better than firms without foreign participation. Moreover, for all three countries studied here, I find no evidence of positive spillovers to domestic firms, on average. In contrast, on average, there are negative spillovers to domestic firms in Bulgaria and Romania, while there are no spillovers to domestic firms in Poland. This suggests a negative competition effect that dominates a positive technology effect. JEL classification: D24, F14, O52, P31.     

Do large capital inflows hinder competitiveness? The Dutch disease in Ethiopia

This article investigates whether large inflows of foreign aid and remittances have had a damaging impact on the Ethiopian Real Exchange Rate (RER). We improve the current empirical literature by: (i) compiling a unique quarterly dataset to provide a larger sample size and enable the modelling of important intra-year dynamics – which should lead to better model specifications; (ii) providing a new empirical approach (Unobserved Components (UC)) to test the ‘Dutch disease’ hypothesis; and (iii) using several cointegration approaches to further test the robustness of our conclusions. Our results suggest that there are two main long-run determinants of the RER in Ethiopia: trade openness is found to be correlated with RER depreciations, while a positive shock to the terms of trade tends to appreciate the RER. Foreign aid is not found to have a statistically significant impact, while there is only weak evidence that remittances are associated with RER appreciations. The lack of empirical support for the ‘Dutch disease’ hypothesis suggests that Ethiopia has been able to effectively manage large capital inflows, thus avoiding major episodes of macroeconomic instability. We believe that most African countries will therefore be able to absorb large inflows of foreign capital without damaging their external competitiveness.     

中国外汇储备风险及优化管理探讨

钉住货币篮子汇率制度在中国应用的研究

主要研究货币篮子的定义,如何确定货币篮子的最优权重,并在此基础上运用协整检验的方法实证分析了我国自2005年7月汇率改革以来人民币货币篮子的运行情况。实证的结果表明,在我们所考察的样本区间内,当人民币篮子货币对美元实际汇率贬值(或升值)1%时,人民币对美元的实际汇率只贬值(或升值)0.32%,表明美元在人民币货币篮子中所占权重较大,人民币对美元的汇率仍缺乏弹性。     

Centralized Private Sector Planning: An Institutionalist’s Perspective on the Contemporary U.S. Economy

It is well accepted among Institutionalist and Post Keynesian scholars that portfolio investment markets are driven by agents' expectations rather than "the fundamentals." This explains, it is argued, why asset and currency prices are so much more volatile than and often clearly out of line with what we would otherwise consider to be their underlying determinants. What is rarely addressed, however, is how those expectations are formed. This paper fills the void by proposing a specific view of agents' expectations based on the mental model they employ to understand currency movements. The paper derives this schematic by examining market participants' psychological propensities and the world view of the subculture of which they are members. It will be shown that the model is consistent with the salient features of the foreign exchange market and it is employed to explain the dollar's fall from 2001 through 2008.     

人民币成为区域主导货币的实证研究——基于汇率视角的考察

从历史和现实的视角看,如果说布雷顿森林体系的崩溃导致了欧洲货币体系的形成和欧元的诞生,那么美国金融危机引发的国际货币动荡正在使东亚各国脱离美元本位,寻找区域内稳定的货币锚,而人民币则有可能成为东亚区域内首选的货币锚。本文拟从多边汇率相互影响的视角出发,实证分析人民币汇率变动态势及其与东亚其他货币之间联动关系的变化(包括其它国际货币汇率的变动对东亚其它货币之间关系变化的比较),从而揭示人民币成为区域锚货币、成为区域主导货币的可能性及其途径、进而了解人民币经济区形成的条件和趋势。     

Liquidity Cost Premia

The purpose of the paper is to find out the borrowing cost premia for those individuals who are liquidity-constrained, or who are first-time buyers of real estate. The analysis uses the similarity of a leveraged purchase with the exercise of a call option to defer the purchase of the asset. Sensible parameters are selected for the option, and simulations are run to identify the cost premia. The main conclusion is that these borrowing costs are prohibitive in central tendency and in dispersion. This means that liquidity-constrained individuals may be given borrowing quotations, but these quoted rates are so high and variable that these individuals are unwilling to borrow.     

基于区域经济实力的储备货币研究

随着我国外汇储备规模的迅速扩大及年新增储备的急剧增加,我国外汇储备币种结构的管理已成为国内外的热门课题。本文通过分析目前我国外汇储备币种结构现状,指出当前过多的美元储备造成了巨大价值损失和战略风险。在收集大量经济数据的基础上,以全新视角构建了基于区域经济实力的储备结构模型,通过对该模型的价值评估,得出该模型有较大的现实意义,最后提出了基于当前我国外汇规模及年增量水平下的国家外储结构调整方案。
