China׳s external policies, including capital controls, managed exchange rates, and sterilized interventions, constrain its monetary policy options for maintaining macroeconomic stability following external shocks. We study optimal monetary policy in a dynamic stochastic general equilibrium (DSGE) model that incorporates these “Chinese characteristics”. The model highlights a monetary policy tradeoff between domestic price stability and costly sterilization. The same DSGE framework allows us to evaluate the welfare implications of alternative liberalization policies. Capital account and exchange rate liberalization would have allowed the Chinese central bank to better stabilize the external shocks experienced during the global financial crisis. 相似文献

In emerging markets, external debt is denominated almost entirely in large, developed country currencies such as the U.S. dollar. This liability dollarization offers a channel through which exchange rate variation can lead to business cycle instability. When firms' assets are denominated in domestic currency and liabilities are denominated in foreign currency, an exchange rate depreciation worsens firms' balance sheets, which leads to higher capital costs and contractions in capital spending. To illustrate this, I construct a quantitative, sticky price, small open economy model in which a monetary policy induced devaluation leads to a persistent contraction in output. In this model, fixed exchange rates offer greater stability than an interest rule that targets inflation. 相似文献

This paper studies utility‐maximizing monetary policy in a two‐country economy with consumer search frictions. Search frictions provide a microfoundation for incomplete exchange rate pass‐through and international deviations from the law of one price (LOP). I show that optimal interest rate policy targets deviations from the LOP and acts to mitigate the effect of search frictions. In a quantitative setting, with internationally correlated technology and preference shocks, optimal policy generates positive cross‐country correlation of nominal interest rates. 相似文献

The use of derivatives to infer future exchange rates has long been a subject of interest in the international finance literature. With the recent currency crises in Mexico, Southeast Asia, and Brazil, work on exchange rate expectations in emerging markets is of particular interest. For some emerging markets, foreign equity options are the only liquid exchange‐traded derivatives with currency information embedded in their prices. Given that emerging markets sometimes undergo currency realignment with discrete jumps in their exchange rate, estimation of risk‐neutral probability density functions from foreign equity option data provides valuable evidence concerning market expectations. To illustrate the use of foreign equity options in estimating market beliefs, we consider Telmex options around the 1994 peso devaluation and find evidence that markets anticipated the change in the Mexican government's foreign exchange policy. 相似文献

The focus of academic discussions of exchange rate policy has shifted in recent years. The new literature on exchange rate regime choice emphasizes considerations relating to the problems of credibility in exchange rate targeting and the connections between exchange rate regime choices and choices of monetary and fiscal policy. Arguments for exchange rate targeting are reviewed. Under most circumstances and for most countries, a system of freely floating exchange rates is likely to be a better choice than attempting to peg the exchange rate. 相似文献

This paper develops and tests a theory of the process by which private agents in an economy form expectations about government policy. Agents form and update their beliefs about the true state of government policy in a Bayesian fashion. The ‘credibility’ of a policy is defined to be the subjective probability that the government is pursuing a 'reform' policy rule. The ‘credibility’ of a reform of monetary or exchange rate policies is a function of the parameters of both monetary and fiscal policies. The theory is applied to the Chilean and Argentine exchange reforms of the late 1970's. 相似文献

We develop a general equilibrium model of an emerging market economy where productivity growth differentials between tradable and non-tradable sectors result in an equilibrium appreciation of the real exchange rate—the so-called Balassa-Samuelson effect. The paper explores the dynamic properties of this economy and the welfare implications of alternative policy rules. We show that the real exchange rate appreciation limits the range of policy rules that, with a given probability, keep inflation and exchange rate within predetermined numerical targets. We also find that the B–S effect raises by an order of magnitude the welfare loss associated with policy rules that prescribe active exchange rate management. 相似文献

按照传统观点,在本国货币遭受投机攻击时,中央银行的典型做法是提高短期利率来捍卫货币和汇率制度。但批评者认为,提高利率会增加经济发展的成本,容易引发信用恐慌和产出减少。通过建立一个基于马尔科夫变换的世代交叠模型可以发现,利率被提的越高,汇率波动率也会随之相应增加。当高利率的货币政策使经济增长放缓甚至衰退,维持汇率稳定的可信度下降时,投机者就会发动对本币的投机攻击。最后在外汇储备耗尽的情况下,中央银行权衡得失后不得不实行浮动汇率制。 相似文献

利率与汇率作为货币资金的对内价格和对外价格,二者具有统一的价值基础,并且相互影响,相互制约,共同在金融市场的资源配置中发挥着重要的作用。利率作为货币资金的对内价格,影响着居民及企业的支出和投资,利率的变化对整个金融市场乃至整个经济生活都有不容忽视的影响。汇率作为货币资金的对外价格,是开放经济条件下,外汇市场上的核心价格变量,受外汇市场、国际收支、跨国资产组合、外汇储备等因素影响。在一国宏观经济中,利率政策和汇率政策是货币政策的重要组成部分,也是一国宏观经济调控的主要政策手段。实际上,在宏观经济运行中,尤其是开放型经济,利率与汇率存在着复杂的关系,甚至有时还存在冲突。因此,对于利率与汇率在传导机制、价值基础、政策运用方面的相互关系的研究,将更有利于发挥货币政策的宏观调控效果。近年来,随着我国的改革开放逐步向纵深方向发展,利率的市场化改革也将进入攻坚阶段。当然,利率市场化改革将对整个金融体系及经济生活产生深远影响,但本文将研究重点放在利率与汇率的联动关系进而更好的研究利率市场化改革对于人民币汇率的影响。 相似文献

The government of a small open economy trying to manage its exchange rate faces a ‘time consistency’ problem. If markets expect implementation of the optimal linear intervention rule, the government will be tempted to ‘defect’: knowing this, markets will expect less activism; and, in the discretionary equilibrium, this is what they get. How far this credibility problem can shift discretionary policy towards a free float is shown in two popular models of floating rates. One way of offsetting the ‘laissez faire’ bias of discretionary policy is to appoint a relatively ‘conservative’ central banker: but, as the time period of policy action and precommitment shrinks towards zero, the required conservative bias is found to go towards infinity. Other institutional features — such as central bank reputation, contracts and intermediate targets — may be crucial for successful exchange rate management. 相似文献

Regaining exchange rate stability has been a major monetary policy goal of East Asian countries in the aftermath of the 1997/98 currency crisis. While most countries have abstained from re-establishing a formal US Dollar peg, they have typically managed the US Dollar exchange rate de facto. We show that most of these countries were able to regain their monetary credibility within a relatively short time period. The Argentine crisis in 2001 caused a minor setback in this process for some countries. We measure the credibility of monetary policy by separating the fundamental and excess volatility of the exchange rate on the basis of a chartist-fundamentalist model. The degree of excess volatility is interpreted as the ability of the central bank to manage the exchange rate via the coordination channel. 相似文献

Can political interference deconstruct credibility that was hardly-earned through successful stabilization policy? We analyze the recent switch in the conduct of monetary policy by the Central Bank of Brazil (BCB). Brazil is the largest Emerging Market Economy to formally target inflation, having adopted the Inflation Targeting (IT) regime in 1999. In the early years of IT, the BCB engaged in constructing credibility with price setting agents and succeeded to anchor inflation expectations to its target even under adverse conditions such as exchange rate crises. We argue that this effort to maintain IT rules-based policy ended in 2011, as a new country president and BCB board came to power. We then discuss the consequences of this credibility loss. Our main results can be summarized as follows: (i) we provide strong empirical evidence of the BCB’s shift toward looser, discretionary policy after 2011; (ii) preliminary evidence suggests that this shift has affected agents’ inflation expectations generating social and economic costs. 相似文献

The paper introduces a model for the joint dynamics of asset prices which can capture both a stochastic correlation between stock returns as well as between stock returns and volatilities (stochastic leverage). By relying on two factors for stochastic volatility, the model allows for stochastic leverage and is thus able to explain time-varying slopes of the smiles. The use of Wishart processes for the covariance matrix of returns enables the model to also capture stochastic correlations between the assets. Our model offers an integrated pricing approach for both Quanto and plain-vanilla options on the stock as well as the foreign exchange rate. We derive semi-closed form solutions for option prices and analyze the impact of state variables. Quanto options offer a significant exposure to the stochastic covariance between stock prices and exchange rates. In contrast to standard models, the smile of stock options, the smile of currency options, and the price differences between Quanto options and plain-vanilla options can change independently of each other. 相似文献

Adopting a single instead of multiple targets can be an effective way to overcome the classic time‐inconsistency problem. The choice of a single mandate depends on the trade openness and the credibility. Reduced‐form empirical results show as central banks become less credible, they are more likely to adopt a pegged exchange rate, and the tendency to peg depends on trade openness. In a model with “loose commitment,” as credibility falls, either an inflation target or a pegged exchange rate is more likely to be adopted. A relatively closed (highly open) economy would adopt an inflation target (exchange rate peg). 相似文献

We consider the valuation of European quanto call options in an incomplete market where the domestic and foreign forward interest rates are allowed to exhibit regime shifts under the Heath–Jarrow–Morton (HJM) framework, and the foreign price dynamics is exogenously driven by a regime switching jump-diffusion model with Markov-modulated Poisson processes. We derive closed-form solutions for four different types of quanto call options, which include: options struck in a foreign currency, a foreign equity call struck in domestic currency, a foreign equity call option with a guaranteed exchange rate, and an equity-linked foreign exchange-rate call. 相似文献

We investigate the effects of stochastic interest rates and jumps in the spot exchange rate on the pricing of currency futures, forwards, and futures options. The proposed model extends Bates's model by allowing both the domestic and foreign interest rates to move around randomly, in a generalized Vasicek term‐structure framework. Numerical examples show that the model prices of European currency futures options are similar to those given by Bates's and Black's models in the absence of jumps and when the volatilities of the domestic and foreign interest rates and futures price are negligible. Changes in these volatilities affect the futures options prices. Bates's and Black's models underprice the European currency futures options in both the presence and the absence of jumps. The mispricing increases with the volatilities of interest rates and futures prices. JEL classification: G13 相似文献

This paper investigates the long- and short-run neutrality of open-market monetary policy in a world of fixed exchange rates and imperfect substitutability between bonds denominated in different currencies. Using an illustrative portfolio-balance model, it shows that when the public discounts the future tax liabilities associated with the national debt and the central bank supports the exchange rate by trading non-interest-bearing foreign assets, open-market policy has a short-run effect, but no long-run effect, on the domestic price level and interest rate. When the foreign-exchange intervention assets earn interest that is rebated to and capitalized by the public, open-market policy loses even its short-run efficacy — the capital-account offset to monetary policy is complete. 相似文献

This paper investigates the nexus between monetary stability and financial stability. We examine, in the experience of EMU between 1994 and 2008, first, the response of the term structure of interest rates, share prices, exchange rates, property price inflation and the deposit–loan ratio of the banking sector (our proxies for financial stability) to changes in the consumer price level and ECB policy rate (our proxies for monetary stability); second, whether and to what extent lower inflation has caused share price stability and how ECB policy rate has reacted to inflation. Using a sign-restriction-based VAR approach, we find that there is a pro-cyclical relationship between monetary and financial stability in the long-run. With a positive inflation shock, we find on average a 2% estimated decline in share prices. This suggests that the interest rate instrument used for inflation targeting is conducive to financial stability. 相似文献

This article studies the equilibrium valuation of foreign exchange contingent claims. Within a continuous-time Lucas (1982) two-country model, exchange rates, interest rates and, in particular, factor risk prices are all endogenously and jointly determined. This guarantees the internal consistency of these price processes with a general equilibrium. In the same model, closed-form valuation formulas are presented for currency options and currency futures options. Common to these formulas is that stochastic volatility and stochastic interest rates are admitted. Hedge ratios and other comparative statics are also provided analytically. It is shown that most existing currency option models are included as special cases. 相似文献

我国货币政策正在向价格型调控方式转型,有必要探索符合我国实际的泰勒规则以确定政策利率目标水平,而如何科学合理地估算潜在产出和自然利率是关键。本文对构建多目标下的中国化泰勒规则时应考虑的因素作了深入探讨,并将金融周期信息纳入我国潜在产出的测算,同时采用基于潜在产出的方法对自然利率进行估算,进而分不同情形尝试估算我国的规则利率水平。结果表明,考虑金融周期信息后的潜在产出在金融扩张期将低于传统方法的估计结果,可为政策制定者有效应对经济运行的过热现象或泡沫化状态提供参考;无论是基于何种潜在产出和自然利率的测算组合,将国内外利差、房价涨幅偏离经济增长程度纳入中国化泰勒规则的构建均是合理的;不同情形下估算的规则利率走势,自2004年以来与货币市场利率走势均较为相近,且2013年后随着利率市场化改革的快速推进,差距呈明显缩小态势,但2017年下半年至2018年期间,受国际宏观形势和国内因素影响,估算的规则利率均快速上扬,与货币市场利率走低形成反差。 相似文献
