Black market for foreign exchange,capital flows and smuggling

The paper develops a geometrical model of the working of a black market for foreign exchange and considers such questions as: Can the black market exchange rate be a guiding instrument to exchange control authorities considering a change in the exchange rate? How does exchange control affect the current and capital account use of foreign exchange in the presence of a foreign exchange black market? What are the implications of changes in trade restrictions (such as import tariffs) for the black market exchange rate, supplies of foreign exchange to exchange control authorities, and current and capital account use of foreign exchange?     

参考一篮子货币的人民币汇率形成机制研究——基于人民币有效汇率目标的分析

文章主要研究如何建立参考一篮子货币的汇率制度,首先分析了人民币对美元汇率、人民币对非美元货币和人民币有效汇率之间的关系。其次研究了从人民币钉住美元货币汇率向参考一篮子货币汇率制度(人民币有效汇率目标)的过渡,以及建立一篮子货币汇率机制的方法和实证模拟研究,并考察了人民币汇率的波动幅度。最后文章认为人民币汇率制度的市场化改革是我国汇率体制改革的最终目标,并给出了本文的主要结论。     

货币政策冲击、外汇干预与汇率 变动的同期与动态关联研究

本文采用SVAR模型以及2005年7月至2011年12月的月度数据，研究了2005年的新汇率改革之后，我国货币政策冲击、外汇干预与汇率间的动态关联。主要发现与结论如下：在货币政策冲击、外汇干预与汇率三者的同期博弈中，外汇干预不能即刻影响同期汇率。利率的上升及广义货币供应量的变动均会对同期名义有效汇率造成一定影响，但不太显著。在三者的动态博弈中，外汇干预是非冲销和有效性得到验证，外汇干预信号的假设可以成立。此外，即使利率的变动并不针对汇率，却带来汇率的大幅波动。名义有效汇率的上升可以有效抑制消费价格指数（CPI）的提高，并且数量型货币政策容易造成CPI的反弹。本文针对研究结论提出了一些政策建议。     

对“价值”概念的几种界定

在经济理论领域内,“价值”是使用得最广泛,同时也是最复杂的一个经济范畴之一。在各种价值理论或观点背后,如何理解“价值”是关键所在。其实,“价值”最初是同交换密切联系在一起的,在交换中人们首先要解决的一个问题是一个物品换取他种物品的数量是多少,亦即交换比例如何确定的问题,当然交换比例应在逻辑上先于交换行为而确定的。进一步的研究表明,在关于交换比例的确定的量的分析之前,还必须回答交换成立的基础这一更加重要的质的问题,然而,这一问题开始进入经济思想家的眼界并不容易,能否意识到并同意这个问题是造成价值理论分歧的根本原因之一。据此,考察经济史上各种价值或价格理论,并对“价值”概念进行了几种界定。     

Central bank intervention and foreign exchange volatility

This paper provides additional empirical evidence on the topic of the effectiveness and the impact of Federal Reserve intervention on U.S. exchange rates. Using a daily measure of exchange rate intervention in the yen/dollar and mark/dollar exchange markets for the period January 3, 1985 to March 19, 1997, this paper finds a statistically significant impact of intervention on spot rates. A generalized autoregressive conditional heteroskedasticity exchange rate equation is used to measure the impact of intervention on exchange rate uncertainty. This study finds that intervention is associated with a significant increase in the interday conditional variance (uncertainty) of both bilateral spot exchange rates. This supports the view of Friedman and Schwartz that exchange rate intervention serves to destabilize the foreign exchange market by introducing additional levels of exchange rate uncertainty.     

The effects of exchange rate uncertainty on exports

We investigate the effects of exchange rate uncertainty on exports in the context of a multivariate framework in which a structural open economy vector autoregression is modified to accommodate multivariate GARCH-in-Mean errors, as detailed in Elder (Elder, J., 2004. Another perspective on the effects of inflation uncertainty. Journal of Money, Credit, and Banking 36, 912–928). Our measure of exchange rate uncertainty is the conditional standard deviation of the forecast error of the change in the exchange rate. We isolate the effects of exchange rate uncertainty on exports and also analyze how accounting for exchange rate uncertainty affects the response of exports to exchange rate shocks. We estimate the model using aggregate monthly data for the United States, over the flexible exchange rate period (since 1973). We use full information maximum likelihood estimation procedures and find that exchange rate uncertainty has a negative and significant effect on US exports. We also find that accounting for exchange rate uncertainty tends to strengthen the dynamic response of exports to shocks in the exchange rate and that exports respond asymmetrically to positive and negative exchange rate shocks of equal magnitude.     

汇率制度能影响外汇市场压力和央行干预吗

按照Stavarek（2007）的方法和标准,分别计算了2002年1月到2011年12月期间人民币对美元的外汇市场压力及中央银行干预指数。结果显示,人民币实行参考一篮子货币的汇率制度与盯住美元的汇率制度相比,不仅没有减轻外汇市场压力,反而加大了外汇干预压力。汇率制度不是影响外汇市场压力的决定因素,但不同的汇率制度却对我国央行外汇市场干预程度产生了较大的影响。在人民币实行参考一篮子货币的汇率制度下,央行干预程度明显降低,汇率决定的市场化程度相应提高。     

Modelling the impact of central bank intervention on exchange rate volatility under inflation targeting

This article empirically investigates the effect of central bank’s foreign exchange interventions on the level and volatility of the Uganda shilling/US dollar exchange rate (UGX/USD) under an inflation-targeting regime. Utilizing daily data spanning the period 1 September 2005, to 31 December 2015, we estimate a foreign exchange intervention model within a GARCH theoretic framework. Empirical results indicate that foreign exchange interventions have had mixed impact on the volatility of the exchange rate. We find that inflation targeting is capable of curbing temporary exchange rate shocks. Empirical results indicate that while order flow is capable of reducing exchange rate volatility, an increase in the operating target rate, the 7-day interbank rate tends to exacerbate exchange rate volatility. Our empirical results are robust to alternative model specifications. We argue that inflation targeting is an effective monetary policy tool for curbing exchange rate volatility.     

人民币汇率改革评析

本文对近20年来人民币汇率改革的实际成效进行评价，笔者认为改革配套措施的短视化倾向制约了汇率市场化改革目标的实现程度。除了参考IMF事实汇率分类法的外部评价，本文以高度市场化的香港离岸人民币汇率作为参考指标，通过定量分析证明境内人民币即期汇率中间价的市场化程度低于收盘价。本文最后强调，深化汇率改革的关键在于完善汇率形成的市场基础以及淡化中央银行汇率责任。     

汇率失调、汇率中性假定和策略汇率

在资本不完全流动的情形下,汇率不仅是体现一国内部经济均衡和外部经济均衡的政策目标,也是一国政府实现其他政治、经济目标的重要政策工具。本文通过考察政府如何以汇率失调为代价,实现政治、经济等战略目标,并以此为基础提出策略汇率的概念,以完善对汇率失调的理论描述和加深对汇率失调内在机制的理解。本文还建立了汇率博弈的政治经济学模型,运用博弈论阐明策略汇率是一个Nash均衡结果。     

预期作用下人民币汇率对出口价格的非线性传递效应研究

对外贸易中贸易款项的支付大多数都在远期,因此对未来汇率变化幅度的预期,会影响汇率对出口价格的传递效应,从而导致汇率传递出现非线性特点。本文对此进行了理论分析,结果显示,预期未来汇率变化幅度较大时,汇率对出口价格的传递程度会下降甚至可能出现负向传递。实证部分本文使用STR模型分析了1999年1月—2016年7月在汇率预期的作用下人民币汇率对出口价格的传递效应。研究发现当人民币汇率预期变动幅度较小时,汇率传递系数为正,人民币汇率升值会导致出口价格上涨,贬值导致出口价格的下降。但是当人民币预期汇率的变化幅度达到一定的阈值后,人民币汇率升值会导致出口价格下降,而贬值会导致出口价格上涨。因此货币当局有必要关注汇率预期尤其是大幅度汇率变化预期的存在对进出口价格和需求的影响。     

Constraints on exchange rate flexibility in transition economies: a meta-regression analysis of exchange rate pass-through

This article uses Meta-Regression Analysis (MRA) to investigate exchange rate pass-through to domestic prices, highlighting differences between transition and developed economies. A total of 23 studies yielded 575 coefficients measuring exchange rate pass-through to import prices and consumer prices for 23 developed and 12 transition economies. The MRA results confirm the finding of many particular analyses that exchange rate pass-through is less than complete. In addition, exchange rate pass-through is higher to import prices than to consumer prices; and exchange rate pass-through is higher in the long run than in the short run. Regarding transition and developed economies, MRA suggests that there is no statistically significant difference in exchange rate pass-through to import prices. Yet, exchange rate pass-through to consumer prices is significantly and substantially higher in transition than in developed economies. This finding is consistent with the caution of many monetary authorities in transition economies regarding exchange rate flexibility.     

Central bank intervention,the current account,and exchange rates

This paper seeks to explain exchange rate and current account or net foreign assets behavior under central bank foreign exchange rate intervention. To analyze central bank intervention we use the current account-net foreign assets identity, as well as the long-run monetary exchange rate model. The intervention function is one where exchange rate deviations from equilibrium are governed by nonlinear adjustments. That is, exchange rate deviations from their long-run equilibrium are such that the degree of reversion towards equilibrium increases with the size of the deviation from equilibrium. In this type of nonlinear function exchange rates determine the current account, and the current account in turn determines exchange rates. This iterative duality contrasts with several portfolio balance models where exchange rates are a function of trade, but trade is not a function of exchange rates. This two way causality is slightly more complex, but is also analytically richer than assuming that exchange rates change solely in a one step process as targeted by central banks. Managing exchange rates is posited to be an active iterative feedback process where intervention changes the current account, which may in turn make further intervention necessary.     

A Monetary Approach to Exchange Market Disequilibrium in Australia: 1975–97

Under a managed float, the central bank may respond to an exchange market disequilibrium by changing either the international reserves or the exchange rate or both such that neither the reserve changes nor the exchange rate movements convey an unambiguous indication of the nature or extent of the disequilibrium. Girton and Roper (1977) suggested an index, namely the exchange market pressure, to capture the disequilibrium. This paper utilises a similar framework to study the exchange market pressure in Australia during 1975–1997 and reserve transactions. It is found that there were substantial reserve transactions in the face of exchange market pressure even after the switch to the floating rate system and the deregulation of the financial system. As a result of these transactions, sharp fluctuations in the exchange rate were moderated and the actual exchange rate appeared to broadly follow the market equilibrium rate.     

人民币汇率形成机制探索

本文分析了人民币汇率形成机制与特点,指出了现行汇率制度存在的缺陷,说明在我国金融进一步开放的背景下,汇率制度的重新选择是我国汇率制度的内在要求,并对我国汇率制度选择路径进行了分析。指出从短期来看,“不可能三角理论”揭示了在资本管制的情况下,我国汇率制度的选择是维持汇率的稳定;从中长期来看,资本项目开放是大势所趋,汇率目标区是中国金融进一步开放中比较适合的汇率制度,也符合中国渐进式的发展改革道路;最后进一步从中心汇率和波动区间的确定、汇率干预等方面提出了实施汇率目标区的具体设想。     

当前汇率制度下中国的货币政策效应分析

在中国当前的汇率制度下,外汇储备持续增加,使得基础货币投放量被动增加,进而导致了经济中流动性过剩问题.提高货币政策独立性的根本途径在于汇率制度改革:完善中国汇率形成的市场机制,培育相对均衡汇率;深化中国外汇管理体制改革,有序开放资本市场;汇率制度改革要与其他政策改革配合协调.     

Exchange in a general market with indivisible goods

We show how to restrict trades in exchange markets with heterogeneous indivisible goods so that the resulting restricted exchange markets, the fixed deal exchange markets, have a unique core allocation. Our results on fixed deal exchange markets generalize classical results on the Shapley-Scarf housing market, in which each agent owns one good only. Furthermore, we define the class of fixed deal exchange rules for general exchange markets, and prove that these are the only exchange rules that satisfy strategyproofness, individual rationality, and a weak form of efficiency.     

基于均衡汇率角度的人民币升值问题分析

在人民币不断升值的大背景下,关于人民币升值的合理性及临界点的探讨已成为热门话题。人民币汇率的合理性问题归根到底是实际汇率是否偏离均衡汇率的问题。在考虑中国转型经济特点和对基本经济因素进行分析后,建立了人民币均衡汇率模型,将估计出的均衡汇率与实际有效汇率进行比较分析,确认人民币确实存在一定的低估,但失调程度不大。因此对于人民币升值我们应保持在适度的范围内,而不应屈从于外在压力。在此基础上进一步提出了人民币汇率调整的方法建议。     

Dyads, triads, and the theory of exchange: Between liberty and coercion

Economists commonly use the Edgeworth box to illustrate the ability of exchange to generate gains from trade. In contrast to this framework of dyadic exchange, we explore triadic forms of exchange where margins of coercion are also present. In the presence of triadic exchange, market transactions are no longer wholly voluntary and instead reflect an admixture of liberty and coercion. We illustrate triadic exchange in the context of credit markets, showing how continual turbulence is a sign of neither market failure nor government failure but is rather a systemic quality of triadic exchange as a system of societal governance.     

外汇储备对我国物价水平的影响——基于协整检验与误差修正模型的分析

协整和格兰杰因果检验结果表明,我国外汇储备与物价水平存在协整关系,且外汇储备是物价水平的格兰杰原因,表明外汇储备增加将对通货膨胀形成压力。但从误差修正模型的检验结果看,我国外汇储备对物价水平的影响在短期内较为有限,其主要原因是我国央行短期内进行大量的外汇冲销操作。因此,我国需要采取有效的措施来缓解通胀压力,如加大央行公开市场业务操作、改革外汇管理体制、适当放宽汇率浮动幅度以及合理使用我国现有外汇储备等。
