Tobin's Q channel and monetary policy rules under incomplete exchange rate pass-through

This paper focuses on the role of the Tobin's Q channel in a two-country framework in which exporting firms set their prices on the basis of local currency pricing. Incomplete exchange rate pass-through significantly affects the Tobin's Q channel in each country compared with the case of complete exchange rate pass-through. We explore whether different specifications of monetary policy enhance social welfare. Regardless of the degree of home bias, a monetary policy rule that stabilizes domestic asset prices attains preferable outcomes to several alternative policy rules considered in our analysis. Notably, there are large gains from employing a domestic asset price rule when the home bias is large. A monetary policy rule that stabilizes the asset prices of both countries results in worse outcomes. Our simulation results suggest that stabilizing asset prices is important in an open economy with incomplete exchange rate pass-through.     

Portfolio Composition and Valuation Effects in Emerging Market Economies*

ABSTRACT

The increase in cross-border assets and liabilities of nations with globalization, implies small asset price and currency movements create large wealth changes. The national net external position is increasingly driven by valuation effects, which the current account does not capture. We analyze valuation effects for a group of seven emerging economies, namely Brazil, Colombia, India, Republic of Korea, Mexico, Peru and Turkey for the time period 2005:Q1-2015:Q4 by scrutinizing their external asset portfolio while controlling for country fundamentals. Both asset and liability categories of Direct Investment equity are found to positively impact valuation. Equity liabilities and debt assets of Portfolio Investment positively influence valuation. Debt liabilities of all kinds of investment negatively impact valuation. Countries with stronger currency tend to gain through valuation effects. An appreciated real effective exchange rate is associated with higher valuation gains. We also found non-linear effects of the composition of external debt portfolio by interacting external portfolio and country characteristics. The external portfolio selection of emerging economies (with more in Direct Investment equity liabilities and Portfolio Investment debt assets) in the period has shielded them from global volatility, and enabled valuation gains.     

COMPARATIVE ANALYSIS OF EXCHANGE RATE APPRECIATION AND AGGREGATE ECONOMIC ACTIVITY: THEORY AND EVIDENCE FROM MIDDLE EASTERN COUNTRIES

The paper examines the effects of exchange rate depreciation on real output and price in a sample of 11 developing countries in the Middle East. The theoretical model decomposes movements in the exchange rate into anticipated and unanticipated components. Unanticipated currency fluctuations determine aggregate demand through exports, imports, and the demand for domestic currency, and determine aggregate supply through the cost of imported intermediate goods. The evidence indicates that the supply channel attributed to anticipated exchange rate appreciation results in limited effects on output growth and price inflation. Consistent with theory's predictions, unanticipated appreciation of the exchange rate appears more significant with varying effects on output growth and price inflation across developing countries.     

Capital Inflows,Exchange Rate Flexibility and Credit Booms

Historically, capital flow bonanzas have often fueled sharp credit expansions in advanced and emerging market economies alike. Focusing primarily on emerging markets, this paper analyzes the impact of exchange rate flexibility on credit markets during periods of large capital inflows. It is shown that bank credit is larger and its composition tilts to foreign currency in economies with less flexible exchange rate regimes, and that these results are not explained entirely by the fact that the latter attract more capital inflows than economies with more flexible regimes. The findings thus suggest countries with less flexible exchange rate regimes may stand to benefit the most from regulatory policies that reduce banks' incentives to tap external markets and to lend/borrow in foreign currency; these policies include marginal reserve requirements on foreign lending, currency‐dependent liquidity requirements and higher capital requirement and/or dynamic provisioning on foreign exchange loans.     

The Effects of Foreign Currency Derivatives on the Monetary Policy Exchange Rate Channel in China

This paper examines changes in the monetary policy exchange rate channel in the presence of foreign currency derivatives (FCD) markets in China. Initially a theoretical macroeconomics model incorporating the exchange rate risk hedging is presented, and this is followed by an empirical test. A theoretical model implies that with more firms using foreign currency derivatives to hedge the exchange rate risk, the effect of the exchange rate on the net exports will be weaker and may even be reversed. The empirical section uses Structure Vector Autoregression (SVAR) models with China's monthly macro data over the 2000–2013 period to assess the impact of the FCD market on the exchange rate channel. Empirical support for the changes in the exchange rate channel transmission is found. By impulse response function (IRF) analysis, with the emergence of the domestic FCD market in China, in the long run the probability becomes higher that the negative effect of RMB appreciation on China's net exports to the US is reversed; meanwhile the negative effects of RMB appreciation on the overall net exports and the net exports to the EU become gradually weaker on average.     

货币国际化水平的影响因素分析——来自国家层面多边数据的经验证据

本文从货币发行国与使用国角度入手，基于国家层面多边（多种货币在多个国家使用)外汇交易数据，采用货币发行分布和货币使用分布指标衡量货币国际化水平，对影响货币国际化水平的因素进行实证分析，结果表明：货币发行国的经济体量越大、金融市场发展程度越高、货币网络外部性越大，其货币国际化水平越高。同时货币发行国与使用国间汇率波动越小、贸易投资额越大、地理和文化间距离越近，则使用国越倾向使用该货币。     

External wealth, the trade balance, and the real exchange rate

We examine the link between the net foreign asset position, the trade balance and the real exchange rate. In particular, we decompose the impact of a country's net foreign asset position (‘external wealth’) on its long-run real exchange rate into two mechanisms: the relation between external wealth and the trade balance; and, holding fixed other determinants, a negative relation between the trade balance and the real exchange rate. We also provide additional evidence that the relative price of nontradables is an important channel linking the trade balance and the real exchange rate.     

对当前提高中国黄金储备规模的思考

自20世纪70年代以来,黄金在国际储备中的地位被主权货币所取代。但近年来,随着美元对国际主要货币汇率的频繁下挫和当前为应对金融危机所采取的定量宽松政策,以美元为主要外汇储备形式的国家面临严重的汇率风险损失和实际资产缩水,提高黄金储备规模由此受到广泛关注。对此,在深入分析全球黄金储备变动情况的基础上指出,一国只有根据其外汇储备的管理目标、风险偏好以及对经济发展长期走势的判断等因素来具体选择增持黄金储备资产的规模和时机并采取科学、审慎、灵活的管理策略,才能实现缓解外汇储备风险、维护国民财富安全的目的。     

The J-Curve

If a country with a balance of payments problem, that is, insufficient foreign exchange receipts to meet foreign exchange requirements, seeks to remedy the situation by currency devaluation, things may get worse before they get better. This so-called J-curve effect occurs if the domestic-currency prices of exports are sticky, whether because they are cost based or subject to longer term contracts, so that export prices in foreign currency fall. Until favourable volume effects outweigh the unfavourable price effect, the balance of payments deteriorates. Such a J-curve effect should be distinguished both from the longer term erosion of the beneficial effects of devaluation as domestic costs and the prices of non-tradables rise and from the apparent J-curve due to the ‘valuation effect’. If the current account is in deficit before devaluation, as will usually be the case, devaluation will widen the deficit in domestic currency because domestic-currency imports rise by a larger amount than exports. This is a pure valuation effect, of no significance for external balance. But it is liable to lead to unduly pessimistic judgements about the effectiveness of devaluation. In Australia during 1985–86, the current account deficit increased by $A3.5 billion, despite substantial depreciation of the $A. The main reason was a sharp deterioration in the terms of trade which is estimated to have worsened the current account by $A4.25 billion. Most of this was exogenous, though J-curve effects may have made a contribution. In addition, the valuation effect contributed a further, illusory, widening of the deficit, valued in domestic currency, by over $A1 billion. To avoid misleading inferences from the valuation effect, it is suggested that the balance of payments should, if possible, be presented in foreign currency.     

Optimal Monetary Policy with Vertical Production and Trade*

This paper explores the optimal monetary policy response to domestic and foreign technology shocks in an open economy with vertical structure of production and trade. We find that any stage‐specific productivity shock in one country may have a transborder spillover effect on the other country via the vertical trade. So when choosing optimal monetary rules, each monetary authority should respond to both home and foreign productivity shocks. Also, the flexible exchange rate cannot replicate the flexible price equilibrium, even under producer currency pricing, due to price stickiness in multiple stages. We also find that the existence of a transborder spillover effect depends on the currencies of price setting. Finally, vertical trade may affect the value of exchange rate flexibility under PCP and LCP setting.     

Foreign equity option pricing under stochastic volatility model with double jumps

This paper considers the challenging problem advocated by Huang and Hung (2005), that is to incorporate the stochastic volatility into the foreign equity option pricing. Foreign equity options (quanto options) are contingent claims where the payoff is determined by an equity in one currency but the actual payoff is done in another currency. Huang and Hung (2005) priced foreign equity options under the Lévy processes. In Huang and Hung's paper, they considered jumps in the foreign asset prices and exchange rates and assumed the volatility as constant. However, many studies showed that constant volatility and jumps in returns are incapable of fully capturing the empirical features of equity returns or option prices. In this paper, the stochastic volatility with simultaneous jumps in prices and volatility is proposed to model foreign asset prices and exchange rates. The foreign equity option pricing formula is given by using the Fourier inverse transformation. The numerical results show that the use of stochastic volatility with simultaneous jumps in prices and volatility proposed to model foreign asset prices and exchange rates is necessary and this approach can help us to capture more accurately the foreign equity option prices.     

人民币成为亚洲储备性货币现状研究

人民币初步具备了区域性货币的条件,但由于其现有国际货币地位低下、影响力不足,人民币在相当长的时间内将处于国际货币竞争格局的弱势地位,要使人民币成为亚洲主要储备性货币,我国必须首先加强自身的轻济实力,这是一国货币国际化的基础;其次,必须考虑和亚洲尤其是东亚形成更紧密经贸关系,在东亚金融合作中,我国应该发挥主导作用;最后,必须完善我国的资本市场和金融市场结构,形成由市场决定的汇率及利率机制。     

影响人民币汇率政策选择的因素--基于决策理论的实证分析

基于决策理论和实证分析方法,得出影响我国政府选择汇率政策的因素是:当前的宏观经济状况对人民币汇率政策的选择的确产生了重要的影响,而外汇储备的高速增长和经常账户余额的状况是2005年汇率政策改革的主要影响因素。因此,当前汇率政策改革是宏观经济形势影响政府效用的结果。     

Exchange Rates and Outward Foreign Direct Investment: US FDI in Emerging Economies

This paper investigates the effect of exchange rates on US foreign direct investment (FDI) flows to a sample of 16 emerging market countries using annual panel data for the period 1990–2002. Three separate exchange rate effects are considered: the value of the local currency (a cheaper currency attracts FDI); expected changes in the exchange rate (expected devaluation implies FDI is postponed); and exchange rate volatility (discourages FDI). The results reveal a negative relationship between FDI and more expensive local currency, the expectation of local currency depreciation, and volatile exchange rates. Stable exchange rate management can be important in attracting FDI.     

Rethinking Deviations From Uncovered Interest Parity: the Role of Covariance Risk and Noise

We examine the ability of the standard intertemporal asset pricing model and a model of noise trading to explain why the forward foreign exchange premium predicts the future currency depreciation with the 'wrong' sign. We find that the intertemporal asset pricing model is unable to predict risk premia with the correct sign to be consistent with the data. The noise-trader model, while highly stylised, receives fragmentary support from empirical research on survey expectations.     

汇率冲击与外汇储备对人民币国际化的动态影响——基于IS-LM-EE模型和SVAR的实证分析

本文基于IS-LM-EE模型构建了汇率冲击效应的理论模型,并利用SVAR方法对1996~2010年的月度时间序列数据,从国际贸易规模、人民币价值稳定、金融业发展三个方面研究了汇率和外汇储备冲击对人民币国际化的动态影响。分析结果表明,短期内人民币渐进和小幅升值虽然给国际贸易带来负面冲击,然而长期内这不仅有利于出口导向型发展模式的转变和国际收支的再平衡,而且也有助于实现低通货膨胀率和人民币的内外价值稳定。此外,外汇储备累积通过货币供给、利率、银行利差等渠道对人民币价值稳定及其国际化形成不可忽略的负面冲击。     

China’s efforts to contain Renminbi’s depreciation and the relating impacts

China began to face Renminbi (RMB) depreciation pressure since 2014Q2, and the 8/11 reform in 2015 exacerbated the RMB depreciation pressure against USD. To contain the depreciation pressure, the People’s Bank of China (PBC) adopted three methods. Firstly, PBC tried to stabilize the exchange rate by selling USD and purchasing RMB, which resulted in the fast shrinking of China’s foreign exchange reserve. Secondly, PBC strengthened the regulation of capital outflows, which caused the stagnation of RMB internationalization. Thirdly, PBC frequently changed the pricing mechanism of the daily fixing of RMB to USD, which led to the reverse of the liberalization of RMB exchange rate. Under the new environment of RMB depreciation pressure and much lower foreign exchange reserve, Chinese government changed its strategies and became more cautious and pragmatic in outward foreign direct investment, RMB internationalization, and Belt & Road Initiative construction.     

Currency Internationalization and the International Price System

Although China, now the world’s second largest economy and largest goods trading nation, has rolled out the ambitious currency internationalization protocol while maintaining strict capital controls for nearly a decade, the implications of this unique reform path on the international economy still present uncertainties. In this paper, we fill in this gap by developing a two country, two-goods model to investigate the impacts of currency internationalization on the international price system, which consists of goods market and factor market interactions. We propose a critical condition of sustainable currency internationalization and reveal high international price sensitivity to exchange rate adjustments.     

Nonfundamental FX trading and excess volatility in credible target zones Theory and empirical evidence

This paper presents a target zone model with imperfect asset substitutability in which exchange rates are driven both by expectations regarding the credible defense of the currency band and foreign exchange traders' stop-loss trading strategies. The model generates excess volatility and nonuniqueness in the density function of the exchange rate. These results obtain independently of whether the stop-loss strategies are known to the market. In an empirical section, the authors find support for the existence of excess volatility for selected countries of the European monetary system (EMS) during the stable EMS period.     

略论中国外汇储备面临的潜在资本损失

本文分析了中国巨额外汇储备面临的由本币升值汇率风险而导致的资本损失。文章从两个角度来研究该项损失:一是从央行资产负债表由于货币错配而招致的现实以及潜在资本损失的角度;二是从以一篮子货币或者一篮子商品来衡量的中国外汇储备国际购买力损失的角度。本文的结论是:中国央行资产负债表面临的资本损失是显著的;中国外汇储备国际购买力的波动显著高于市场价值的波动,尤其是用油价来衡量的外汇储备购买力波动相当剧烈。
