货币错配与银行危机和货币危机

货币错配是新兴市场在经济全球化过程中所无法避免的问题,它具有净外币负债和净外币资产两种表现形式.在新兴市场中,只要其银行体系存在大规模的货币错配,不管表现为哪一种形式,都会增加其金融体系的脆弱性;而且在宏观或微观经济基本面恶化的情况下,可能引发银行危机甚至是货币危机.此外,当出现不利冲击时,银行体系中存在货币错配将会导致其资产和负债的期限错配进一步恶化.

Currency Crises and the Modified Currency Board System in Singapore

This paper argues that the currency board system, while ideal for developing countries, will need to be modified for the more advanced developing countries like Singapore. Serious conflicts between internal and external targets could be minimized if it is modified by allowing some flexibility in the exchange rate. Lessons from Singapore on controlling inflation and warding off currency attacks were drawn to support the argument.     

货币国际化与货币互换市场发展关系的实证分析

笔者研究了2000年10月～2011年3月美国货币互换市场的发展与美国货币国际化程度的关系,结果发现:货币互换市场价格变动的冲击短期内对国际金融市场中美元国际化带来的冲击是难以界定的,而从长期的角度来看,货币互换市场促进了国际金融市场中以美元计价的金融产品的推出,推进了美元国际化.美元的国际化在短期内会扩大美国国内货币互换市场规模,但是,从长期的角度而言,货币国际化的推进不会对货币互换市场带来任何影响.笔者认为中国需要优先发展人民币的货币互换市场,这样,可以有效地抵御海外金融市场的冲击,以达到人民币成为国际经济往来中储备货币的目的.     

Currency Quandary: The Choice of Invoicing Currency under Exchange-Rate Uncertainty

Recent studies have derived optimal invoicing strategies for an exporting firm when exchange rates are uncertain. However, these studies fail to explain trade transacted in a third currency (vehicle currency). In this study, we extend existing models to include the possibility that trade occurs in a vehicle currency. We find that under conditions stipulated by existing models, vehicle-currency invoicing is not preferred. The presence of a competing exporter under imperfect competition, however, can induce vehicle-currency pricing. This is consistent with trade in many primary commodities dominated by few exporters with many importers but where commodities are not perfectly homogeneous.     

亚元:区域性货币合作制度新选择

欧元与美元“二元化”的国际货币体系,使中国在2003年获得9.1%的经济增长率,意大利仍然凭借欧元地位,以0.3%的经济增长速度使其世界排名从第七位超越中国再次跃居第六位,这使亚洲各国更加明确,加强本地区货币合作将改变目前亚洲在国际竞争中所处的不利境地。要使亚洲经济不再作为大国货币的附属品,必须改变现存不公平的国际货币制度,加强地区间金融协调与合作,创立一个稳定的亚洲统一货币才能稳定亚洲金融市场,促进亚洲经济健康发展。在当前形势下分析现存国际货币制度缺陷及现状,讨论亚洲货币合作标准及亚元制度建设进程显得十分重要。     

Solving the Currency Conundrum

This paper reviews the prospects for the exchange rate system in different parts of the world. It discounts radical changes like a single world currency and a trio of regional monetary unions: in Europe, where intergration is political as well as economic and financial, the euro should provide the basis for an expanding zone of monetary stability; in the Americas, in contrast, dollarization is likely to be the solution for countries with strong financial links to the USA that find it difficult to run an autonomous monetary policy; and in Asia, continued floating is the only plausible outcome, given the obstacles to the alternatives.

Currency interdependence and dollarization

This paper constructs a search model of currency interdependence, and uses it to examine how in dollarized economies the foreign currency reacts to various shocks to the domestic currency. Currency interdependence is generated by allowing sellers to take into account their outside option of trading with the domestic currency while bargaining with buyers holding the foreign currency. The shocks consist in movements in the domestic interest rate, domestic inflation and the domestic currency’s market power. We show that if the purchasing power of the domestic currency is low, any shock that increases its value, such as a higher domestic interest rate, translates into a depreciation of the foreign currency. However, the result is opposite when the purchasing power of the domestic currency is high. We show that when money is indivisible these shocks can drive in or out the foreign currency. When money is divisible, this currency substitution effect is more limited. We use our results to discuss the opportunity of various de-dollarization policies and show that some can be counterproductive.     

An Intertemporal Currency Board

The paper shows that the traditional wisdom of raising interest rates to defend a currency enriches rather than punishes the speculators. Furthermore, using high interest rates as a currency defense tool often produces the opposite effect in times of crisis. A new approach is proposed of using Hong Kong dollar put options as an explicit commitment by the government. The put option itself acts like an intertemporal currency board in keeping the linked exchange rate over time. This costly signaling produces a separating equilibrium that distinguishes the strength of the Hong Kong dollar from the other Asian currencies that were under pressure in 1997.     

Local Currency Pricing versus Producer Currency Pricing: Direct Evidence from German Exporters

Abstract. In new open-economy macroeconomic models, the assumption on the pricing behavior of firms in international trade plays a central role. Whether firms apply producer currency pricing (PCP) or local currency pricing (LCP) crucially affects, for example, the design of optimal monetary policy or the choice of the optimal exchange rate system. However, empirical evidence has so far been mixed and is furthermore mostly of an indirect nature. This paper draws direct evidence on the price-setting behavior of German exporters from a questionnaire-based survey. We find that PCP applies in more integrated markets. Differences between LCP firms and PCP firms mainly exist with respect to the use of mark-ups and in the validity of the law of one price for their respective products.     

The Optimum Currency Area Puzzle

The theory of optimum currency areas, suggesting the redrawing of currency areas across countries or splitting of national money into several currencies, is at odds with the one-money-one-country pattern that has dominated monetary history for 26 centuries. This paper puts forward an equilibrium approach which, by stressing the influence of the border effect on intranational adjustment, solves the puzzle and analyzes the closely related issue of the viability of monetary unions and regional specialization.     

International Trade and Currency Exchange

On the international scene, away from national legal rules, the use of different currencies is largely due to the operation of the "Invisible Hand". The paper develops a three-country model of the world economy. This links real trade patterns with currency exchange structures in a general equilibrium framework which includes transaction costs on foreign exchange markets. In the presence of strategic complementarities, there are multiple equilibrium structures of currency exchange for a given underlying real trade pattern. The existence conditions of these different equilibria are characterized, using the trade links between countries as the key parameters. Finally, repercussions on world output of the choice of a currency exchange structure are analysed.
"So much of barbarism, however, still remains in the transactions of most civilized nations, that almost all independent countries choose to assert their nationality by having, to their own inconvenience and that of their neighbours, a peculiar currency of their own."

Currency Options and Export-Flexible Firms

This paper examines the production and hedging decisions of a globally competitive firm under exchange rate uncertainty. The firm is risk averse and possesses export flexibility in that it can distribute its output to either the domestic market or a foreign market after observing the realized spot exchange rate. To hedge against its exchange rate risk exposure, the firm can trade fairly priced currency call options of an arbitrary strike price. We show that both the separation and the full‐hedging results hold if the strike price of the currency call options is set equal to the ratio of the domestic and foreign selling prices. Otherwise, neither result holds. Specifically, we show that the optimal level of output is always less than that of an otherwise identical firm that is risk neutral. Furthermore, an under‐hedge (over‐hedge) is optimal whenever the strike price of the currency call options is below (above) the ratio of the domestic and foreign selling prices.

Explaining Russia's Currency and Financial Crisis

The paper attempts to sketch a framework for understanding Russia's August 1998 financial and currency crises with reference to the main theories put forward so far. Our thesis is that, while not fitting easily into any pre-existing framework, the Russian crises shares many features of first-generation models inasmuch as it was largely due to inconsistencies among an overvalued peg, tight money, and an evident inability to address the fiscal deficit. In other terms, it derived from the incompatibility between standard IMF stabilisation policies and the difficulties that Russia was facing as a transition economy. On the other hand, by touching both currency markets and the banking sector, the Russian Episode shares also important features of the twin crises framework.The analysis considers the role of exchange rate movements and capital flows on Russia's rising vulnerability, fiscal problems and the building up of the public debt. It assesses the state of the Russian Banking sector and discusses the contagion effects of the Asian crisis and policy response. It shows how the core of the Russian crises lies in an unsound, IMF-backed, defence of the rouble, which in 1998 had become increasingly unsustainable.     

Currency crisis transmission through international trade

The Eurozone recent crisis has shown how balance of payments problems in less developed European Monetary Union (EMU) member countries can affect EMU trading partners, spreading the crisis to a larger group of countries. This paper introduces a three-country dynamic general equilibrium model to analyze whether and how terms of trade effects can generate a spillover effect or a currency crisis transmission between countries. Specifically, using a two period model, it incorporates world market clearing conditions for tradables into a new theoretic model, analyzes net capital flow movements between countries, and establishes cross-border macroeconomic linkages. This paper shows how a currency crisis can transmit through the real (trade) sector channel of the economy.

Currency hedging with options and futures

This paper examines the optimal hedging decision of a competitive exporting firm which faces concurrently hedgeable exchange rate risk and non-hedgeable price risk. We show that the hedging role of currency options is due to two distinct sources of non-linearity: (i) the multiplicative nature of the price and exchange rate risk; and (ii) the marginal utility function of the firm. In particular, we show that a long put option position is optimal when the price risk is negatively correlated with the exchange rate risk and/or the firm is prudent.
