Estimating Korea's Exchange Rate Exposure

This paper conducts an empirical analysis of the exchange rate exposure of 392 Korean firms by employing not only changes in the exchange rate but also the standard deviation of exchange rates as foreign exchange risk. A logit model is also used to identify the major factors in exchange rate exposure. The empirical results in the case of using the standard deviation of exchange rates suggest that: the number of firms showing significant exchange rate exposure has been relatively increasing; exchange rate exposure is more likely for export‐oriented manufacturing industries than for nonmanufacturing industries; and large firms using hedging methods are likely to show a low degree of exchange rate exposure.     

Renminbi exchange rate exposure: evidence from Chinese industries

This paper investigates sensitivity of stock returns of industry-sorted Chinese firms with respect to renminbi exchange rate movements. Strong evidence of significant exposure is documented for 7 out of 16 Chinese industries. Evidence is also found of the size asymmetry effects. In addition, we explore the characteristics of the exposure, and detect evidence of significant exposure among non-exporters in some of the industries. Special attention is given to examining the time-varying exposure under the impact of the new Chinese exchange rate regime in place since 2005, in which even stronger exchange rate exposure is reported. The conditional exposure estimated in this paper also reveals the close relation between stock returns and changes of the renminbi exchange rate.     

The Response of Trade Prices to Exchange Rate Changes

The present paper examines export and import pricing behavior following exchange rate changes in small, open economies. Using a monopolistic model, this study reveals that export and import prices should change but not in proportion to exchange rate movements. The policy implication of the results is that the pricing to market phenomenon could be a critical factor in explaining the evolution of the external trade balance with strategic interaction present in the case of prices on tradable goods. Consequently, the use of an exchange rate policy in the case of external imbalances should be a central issue within the broader context of how market structure and conduct affect the optimal traded goods prices.     

Exchange Rate Pass‐through to China's Export Price: A Product‐level Investigation

Exchange rate movement usually results in changes in the production costs of exporting firms, and, therefore, the prices and the quantity of traded products. The present paper constructs a theoretical model to demonstrate that export products with higher productivity, or with larger market share, or of higher quality will experience a less complete pass‐through. Using the six‐digit harmonized system export data from the CEPII database over the period of 2000 to 2013, the present paper examines how product heterogeneity affects the exchange rate pass‐through of Chinese exports. The empirical results show that the most competitive Chinese export products, or those least affected by exchange rate risks, are those of higher quality, with higher technological complexity and at the high end of the international value chain. Therefore, Chinese exporting firms should pay more attention to improving export quality and upgrading technology to better cope with exchange rate risks and to enjoy more bargaining power in the international market.     

Some Methodological Issues on Estimating Foreign Exchange Exposure of US Multinational Firms: Evidence from the Asian Crisis

Abstract

This article asks whether sample specification of firm, period, and exchange rate matters in estimating foreign exchange exposure of US multinational firms. By sampling US firms that had Asian sales and assets from 1996 to 1998, we find that the firms’ returns are more likely to be significantly exposed to the Asian-oriented exchange rate changes for the Asian crisis, when the exchange rate changes were unexpectedly sizable. Also, by examining firms’ exposure in the share of Asian sales and assets, we find that the firms are more exposed as their operations are more involved in the Asian region.     

Openness and Real Exchange Rate Volatility: In Search of an Explanation

The puzzle that real exchange rates are less volatile in open economies is an important challenge to exchange rate theory. Adjustment of domestic prices to nominal exchange rate movements can account for only a small proportion of this effect. Real and nominal shocks display no obvious correlation with openness. It is shown here that real effective exchange rates are more strongly mean-reverting in more open economies, even after controlling for exchange rate regime effects. This is predicted by the theory of current account sustainability, because of its emphasis on ratios to GDP rather than to trade flows.

人民币汇率的长短期影响因素对比分析和汇率波动主导因素界定

论文采用2000-2013年间的月度数据,构建了马尔科夫区制转换模型,在此基础上研究了人民币汇率的长短期影响因素,实证结果显示,短期影响因素中国内通货膨胀、国际市场利率和国内利率的一个正向冲击在10个月的反应期内能造成人民币汇率升值或贬值的累积值分别达到约0．75、0．35和0．9。长期影响因素中贸易条件、货币供给和外汇储备的一个正向冲击在30个月的反应期内能造成了人民币汇率升值或贬值的累积值分别达到约5．5、5．5和16。然后结合模型区制间转换累积脉冲响应和模型区制时间分布可以确定我国某一时期汇率变动的主导因素。分析发现,2007年5月-2008年4月这一时期我国汇率升值变动主要由短期因素决定,2011年3月-2012年1月这一时期我国汇率升值变动却主要由长期因素决定,说明我国不同时期汇率变动趋势决定因素可能不一致。     

The Behavior of the Real Exchange Rate Under Fixed and Floating Exchange Rate Regimes

This article investigates the behavior of real exchange rates under fixed and flexible exchange rates. Using data from both the Bretton Woods and the modern floating periods, we decompose real exchange rate movements into components attributable to supply shocks, real demand shocks, monetary shocks, capital flows shocks, and real oil price shocks. Empirical results show that real demand shocks are an important source of real exchange rate movements under both fixed and flexible rates, while monetary shocks are negligible. Supply and oil price shocks seem to be more important under Bretton Woods, while capital flows shocks seem to explain a relatively higher proportion of real exchange rate movements under the modern floating period.     

汇率宏微观属性下的均衡汇率问题反思——兼议人民币汇率稳定性

汇率决定理论大致可分为传统汇率决定理论、现代汇率决定理论和宏观经济均衡汇率理论三个阶段。这三个阶段理论的共同特点是,以均衡汇率为核心标准,评判一国汇率水平的合理性。文章从汇率宏观和微观属性的角度出发,对均衡汇率的理念与现实意义进行了重新审视和分析,并就人民币汇率稳定性提出相关参考意见。     

Currency Exposure in China under the New Exchange Rate Regime: National Level Evidence

The present paper studies China's national level currency exposure since 2005 when the country adopted a new exchange rate regime allowing the renminbi (RMB) to move towards greater flexibility. Using generalized autoregressive conditional heteroskedastic and constant conditional correlation‐generalized autoregressive conditional heteroskedastic methods to estimate the augmented capital asset pricing models with orthogonalized stock returns, we find that China equity indexes are significantly exposed to exchange rate movements. In a static setting, there is strong sensitivity of stock returns to movements of China's tradeweighted exchange rate, and to the bilateral exchange rates except the RMB/dollar rate. However, in a dynamic framework, exposure to all the bilateral currency pairs under examination is significant. The results indicate that under the new exchange rate regime, China's gradualist approach to moving towards greater exchange rate flexibility has managed to keep exposure to a moderate level. However, we find evidence that in a dynamic setting, the exposure of the RMB to the dollar and other major currencies is significant. For China, the challenge of managing currency risk exposure is looming greater.     

实际汇率与居民消费风险分担的动态关系——基于预期的视角

通过考虑居民预期行为的作用，实际汇率与居民消费风险分担的动态关系是一个附带预期的渐进调整过程。在利用东亚9个主要经济体的数据对该关系进行研究后发现：（1）东亚各国居民之间的消费风险分担程度较低，但是从2000年之后，居民消费风险分担程度在逐渐提高；（2）实际汇率变动基本上没有平滑东亚各国（地区）居民的消费变动；（3）持有静态预期行为的居民朝向长期消费风险分担均衡的调整程度较小，并且该调整速度较慢，同时持有理性预期行为的居民、持有适应性预期行为的居民背离长期消费风险分担均衡的调整程度较大，并且该调整速度较快，这是造成非完全消费风险分担均衡的重要原因。     

Exchange rate exposure of sectoral returns and volatilities: Evidence from Japanese industrial sectors

Most studies of exchange rate exposure of stock returns do not address three relevant aspects simultaneously. They are, namely: sensitivity of stock returns to exchange rate changes; sensitivity of volatility of stock returns to volatility of changes in foreign exchange market; and the correlation between volatilities of stock returns and exchange rate changes. In this paper, we employ a bivariate GJR-GARCH model to examine all such aspects of exchange rate exposure of sectoral indexes in Japanese industries. Based on a sample data of fourteen sectors, we find significant evidence of exposed returns and its asymmetric conditional volatility of exchange rate exposure. In addition, returns in many sectors are correlated with those of exchange rate changes. We also find support for the “averaged-out exposure and asymmetries” argument. Our findings have direct implications for practitioners in formulating investment decisions and currency hedging strategies.     

Exchange Rate Instability： Japan＇s Micro-Macro Experiences and Implications for China

Since 1985, the yen‐dollar exchange rates repeatedly fluctuated and climbed to a level that could not be justified by economic fundamentals. The impacts on the Japanese economy were serious and far‐reaching. Since 21 July 2005, China has been moving toward a more flexible exchange rate regime. Keeping RMB exchange rates basically stable and providing Chinese industries with means to hedge exchange rate risks are essential for China's sound economic development. Edited by Zhinan Zhang     

Assessing the Equilibrium Exchange Rate of the Malaysian Ringgit: A Comparison of Alternative Approaches

Drawing on the behavioral equilibrium exchange rate and the fundamental equilibrium exchange rate approaches, this paper assesses the equilibrium value of the real effective exchange rate of the Malaysian ringgit over the past 25 years. For 2005, when the Malaysian authorities exited from the peg with the US dollar, both models determine a slight undervaluation of the currency. Openness and real GDP per capita have been the main drivers of real exchange rate movements in the past, although non-tradable productivity, government consumption, and net foreign assets have also had a sizable impact. The paper also highlights the limitations of applying the two approaches in the context of emerging countries.     

汇率升值对就业影响的中日比较

关于就业问题,以往的研究主要从就业总量与就业结构两个角度进行探讨,本文对就业结构的研究进行了拓展,在实证研究中引入汇率,运用协整和误差修正模型对日中两国实际汇率与第三产业产值比重和就业比重之间的关系进行了国别比较。实证结果表明,从长期看日本第三产业就业比重上升与实际汇率升值正相关,而中国的相应变量间不存在类似长期关系。比较分析得出结论:只有在汇率适度浮动,资源在部门间流动壁垒减少这两个条件满足时,汇率升值才会产生资源配置作用,推动劳动向非贸易部门转移,逐步优化就业结构。     

汇率变动的农业贸易效应模型述评

已有文献从微观和宏观视角构建了汇率变动的农业贸易效应模型,指出汇率水平变动、汇率波动性风险负面影响农业贸易流。尽管这些模型得出了一致的结论,但却根基于不同的假定之上,由此可将其归结为出口供给模型、进口需求模型、出口供给进口需求均衡模型、出口需求方程、引力模型五类。对于前三类模型,要得出汇率波动性风险负面影响农业贸易流的结论,必须依赖于厂商风险厌恶假设。未来研究需要基于发展中国家特点提出假设条件拓展已有模型,同时在模型中引入合适的变量,以突出农业贸易特征。     

Tail Causality between Crude Oil Price and RMB Exchange Rate

In this paper we assess the causal relationship between international crude oil price changes and the RMB exchange rate using daily information from 21 July 2005 to 5 April 2017. In addition to linear causality tests, we employ quantile causality test to identify prior imperceptible causality in quantiles. We find a causal relationship from crude oil price to exchange rate at each quantile interval, but the reverse only appears in tail. This may help to explain why a traditional linear test fails to capture the causality from exchange rate to crude oil price as the quantile causalities in tails are canceled out by each other. Moreover, using RMB as the settlement currency in crude oil trade can weaken the prior significant causal relationships between crude oil price and exchange rate, whereas the reform of exchange rate marketization reignites the tail causalities from exchange rate to crude oil price. These findings recommend a wider use of domestic currencies in crude oil trade to avoid risk from the crude oil market.     

Exchange Rate Volatility,Heterogeneous Firms and Market Concentration

With the gradual promotion of market‐oriented reform of the RMB exchange rate, the fluctuation range of the RMB exchange rate is increasing. How to deal with the impact of exchange rate volatility on Chinese exports is an important challenge faced by China. This paper finds that although exchange rate volatility, as a whole, has a negative impact on exports, high‐productivity exporters are less prone to exchange rate volatility shock in both intensive and extensive margins. As high‐productivity firms are less affected by exchange rate risk, they account for larger market shares. This paper, from a new perspective, provides evidence that increasing productivity helps mitigate the negative impact of exchange volatility on exports.     

The Importance of the Exchange Rate Regime in Limiting Misalignment

This paper explores how the choice of a country’s exchange rate regime may affect exchange rate misalignment for developing and developed countries. A measure of misalignment is obtained by using a panel cointegration vector estimator. This paper finds that for developing countries, an intermediate exchange rate regime (a regime falling somewhere between a pure float and a hard peg) is most effective in preventing exchange rate misalignment. Additionally, the choice of an exchange rate regime as a means to limit misalignment matters for developing countries, but does not seem to matter for developed countries.     

Exchange Rate Disconnect in a Standard Open-Economy Macro Model

This paper demonstrates that the well-documented exchange rate disconnect can be explained within traditional exchange rate models. It is shown that even if the underlying fundamentals are invariant across exchange rate regimes, equilibrium real exchange rates are more volatile under flexible nominal exchange rates than under fixed rates. In particular, fixed rates reduce the requisite adjustments of the real exchange rate in response to both nominal and real shocks relative to a floating-rate scenario.
