Exchange Rate Pass-through in a Small Open Economy: the Importance of the Distribution Sector

The degree of exchange rate pass-through to domestic goods prices has important implications for monetary policy in small open economies with floating exchange rates. Evidence indicates that pass-through is faster to import prices than to consumer prices. Price setting behaviour in the distribution sector is suggested as one important explanation. If distribution costs and trade margins are important price components of imported consumer goods, adjustment of import prices and consumer prices to exchange rate movements may differ. We present evidence on these issues for Norway by estimating a cointegrated VAR model for the pricing behaviour in the distribution sector, paying particular attention to exchange rate channels likely to operate through trade margins. Embedding this model into a large scale macroeconometric model of the Norwegian economy, which inter alia includes the pricing-to-market hypothesis and price-wage and wage-wage spirals between industries, we find exchange rate pass-through to be quite rapid to import prices and fairly slow to consumer prices. We show the importance of the pricing behaviour in the distribution sector in that trade margins act as cushions to exchange rate fluctuations, thereby delaying pass-through significantly to consumer prices. A forecasting exercise demonstrates that exchange rate pass-through to trade margins has not changed in the wake of the financial crises and the switch to inflation targeting. We also find significant inflationary effects of exchange rate changes even in the short run, an insight important for inflation targeting central banks.     

汇率的不确定性、投资区位选择与公司内贸易

本文通过建立投资国一受资国一国际市场的三国框架,分三种投资区位的国际生产模式,就汇率冲击对垂直型FDI的区位选择和公司内贸易的影响进行分析。研究表明：（1）当区位成本优势不能抵消汇率不确定性导致的损失时,跨国企业将会调整投资区位决策,考虑撤资回母国;（2）当汇率相对波动幅度处于某一范围时,跨国企业具有较强烈的倾向将投资从原东道国转移到其引资竞争国;（3）汇率不确定性对出口价格的传导效应,具有不完全性特点。出口价格的汇率波动风险弹性取决于国际市场的外部竞争度以及子公司组装成本占国际市场该产品价格的比重;（4）汇率波动风险对公司内贸易余额的传导程度具有不确定性。随着汇率风险程度的逐步加大,其对公司内贸易余额的影响作用渐强,逐步从弱弹性转化为较强弹性的传导。     

贸易模式与不完全汇率传递——基于扩展的古诺模型的解释

本文采用一个扩展的古诺模型分析证明了贸易模式与不完全汇率传递的关系。首先,本文从破解人民币升值背景下中国贸易规模和贸易顺差仍持续增长这一谜题出发,分析了中国贸易模式和出口结构特征,描述了中国在国际生产价值链上的角色,阐述了垂直型产业内模式和中间产品占比较大的贸易结构对人民币汇率传递水平的影响。其次,对Dornbusch采用的古诺模型进行拓展,引入贸易模式变量,构建了一个局部均衡的理论模型。模型分析表明,产业市场结构、本国供应商的市场地位和贸易模式是影响出口价格的汇率传递水平的重要因素。最后,根据模型分析结论,提出相应的政策建议。

本文在汇率价格传递理论分析的基础上,采用自回归分布滞后模型在细分商品层面就人民币汇率变动对进口商品价格的传递进行了研究。研究发现,汇率传递的大小在我国不同行业的不同商品间有较大差异,我国进口商品价格存在不完全传递现象,甚至部分商品存在逆传递。对于原材料类产品,汇率对价格的影响是相当迅速的,随着深加工的进行影响会出现时滞。     

Vertical trade and China's export dynamics

This paper examines how China's exports are affected by exchange rate shocks from countries that supply intermediate inputs to China. We build a simple small open economy model with intermediate goods trade to show that due to the intra-regional trade in intermediate goods, a devaluation of other Asian currencies does not necessarily hurt China's exports, as imported intermediate goods could become cheaper. The effect of intermediate goods costs depends critically on the share of intermediate goods used in China's export goods production and the degree of exchange rate pass-through in imported intermediate goods prices. If prices for intermediate goods are not very sticky, the effect through this channel could be large, and China's exports could even benefit. We find that these findings do not depend on China's choice of currency invoicing between the RMB and the US dollar or the choice between fixed and flexible exchange rate regimes.     

Exchange Rate Pass-through,Unemployment and Optimal Implementable Monetary Policy Rule for Emerging Economies

Abstract

This paper develops a small open economy model with nominal rigidities and search-matching frictions to study the implications of exchange rate pass-through for monetary policy in emerging countries. I find that, with complete exchange rate pass-through, the optimal policy rule features unemployment targeting as well as inflation targeting. However, the welfare gain from responding to unemployment fluctuations diminishes as the rate of exchange rate pass-through to import prices decreases. With low exchange rate pass-through, the optimal monetary policy is strict inflation targeting.

固定汇率制度下的财政政策:开放经济宏观经济学的拓展

本文主要建立在新开放主义宏观经济学理论上,进一步拓展和分析不同财政政策在固定汇率制度下对国民经济的影响,如消费、产出与汇率等。通过引入迭代模型的基本框架从而打破传统的李嘉图等价假设,我们发现因为有限生命代理人把所购买的国债看作是一种净财富,所以通过发行债券融资而导致的政府支出暂时的增加毫无疑问地将会增加本国居民相对于国外居民的消费水平。而另一方面,由于汇率水平固定不变和短期的价格粘性,政府支出增加的部分将平均分配给本国和外国商品。因此,政府支出暂时的增加将会减少本国的净国外资产头寸。而对于货币政策来说,本国居民相对消费水平的增加将导致本国货币升值压力,本国中央银行为了维系固定汇率水平不得不被动地增加货币供给。     

Exchange Rate Pass-through in China

During the second half of 2007 and early part of 2008 when there were intense inflationary pressures in China, RMB appreciation was advocated as a means of helping to curb inflation. The effectiveness of appreciation in controlling inflation depends on the impact of exchange rate movements on import and domestic prices. Our analysis finds fairly large and speedy exchange rate pass-through （ERPT） to import prices： 50 and 60percent for the short run and long run, respectively. However, the degree of ERPT decreases along the price chain from upstream to downstream prices. ERPT for consumer prices, the most downstream prices, is much milder and has substantial lags. A 10-percent rise in the nominal effective exchange rate will dampen consumer prices by 1.1 percent within a year, with very little pass-through in the first half year, and by 2.0percent over the long run. These findings, particularly the ERPT to consumer prices, suggest that RMB appreciation can help to reduce inflationary pressures over the longer term. However, it is unlikely to provide rapid relief to the current round of high inflation because of the long lags in ERPZ. The RMB needs to strengthen in effective terms to exert the desired dampening impact on prices.     

Exchange Rate Regimes: Middling Through

Abstract

The appropriate exchange rate regime, in the context of integration of currency markets with financial markets and of large international capital flows, continues to be a policy dilemma. It is found that the majority of countries are moving towards somewhat higher exchange and lower interest rate volatility. Features of foreign exchange (forex) markets could be partly motivating these choices. A model with noise trading, non-traded goods and price rigidities shows that bounds on the volatility of the exchange rate can lower noise trading in forex markets; decrease fundamental variance and improve real fundamentals in an emerging market economy (EME); and give more monetary policy autonomy. Central banks prefer secret interventions where they have an information advantage or fear destabilizing speculation. But in the model discussed in this article, short-term pre-announced interventions can control exchange rate volatility, pre-empt deviations in prices and real exchange rates, and allow markets to help central banks achieve their targets. The long-term crawl need not be announced. In conclusion, the regime's applicability to an EME is explored.

人民币汇率变动对中欧出口价格的传递效应

本文探讨了人民币升值对向欧元区出口价格的汇率传递效应及其对中欧贸易顺差的调节作用。作者利用1999年1月至2006年12月的月度数据,在SITC一位数商品分类层面上,考察了人民币/欧元汇率变动对中国向欧元区出口价格的影响。实证结果显示,不同类商品的出口价格汇率传递弹性存在较大差异,汇率变动引起中国向欧元区出口价格较大幅度的调整,人民币升值对占中欧出口总额一半以上的第6类和第7类商品出口没有抑制作用。因此,人民币升值对中欧贸易顺差的调节作用有限。     

美元定价、汇率传递与美元贬值对东亚经济的冲击

本文对东亚国家和地区国际商品贸易定价货币的选择进行了考察,分析了东亚汇率传递的特征及美元贬值对东亚经济的影响与冲击,并提出中国的对策。研究发现:美元定价已成为外部冲击向东亚经济传导的重要渠道;美元定价导致美国和东亚之间只存在单向的汇率传递,从而削弱约束美元贬值的内在机制;在美元定价条件下,东亚国家在面对美元贬值对经济的刺激作用时乐观其成,但是在面对美元贬值所带来的"滞胀"冲击时却没有有效的隔离机制。     

Sectoral Price Movements under the Yen Appreciation

This paper analyzes the movements of tradable goods prices in Japan. The import price indices and the export price indices are matched with the domestic wholesale price indices at the most detailed level available for Japan, and the pricing behavior in the yen appreciation period (1985–1995) is examined. In the import-side analysis, we investigate how far the price movements under currency appreciation deviate from the law of one price. We find that internal–external price differentials have surprisingly expanded for most of the products since 1985. For a number of commodities, the import prices do not decline as far as the exchange rate appreciates, and the domestic wholesale prices do not decrease as far as the import prices decline. Although the expanded price gaps cannot necessarily be interpreted as a result of deliberate trade barriers, they suggest that some sort of handicap is imposed on imported goods and the large fraction of rent generated by the yen appreciation is intercepted in the middle. In the export-side analysis, the relationship between the globalization of firms' activities and export pass-through is investigated. Our cross-sectional regression analysis indicates that the export path-through rates tend to be low when the value added ratios of foreign production of Japanese firms are high. Low export pass-through under currency appreciation is often interpreted as a result of firms' attempts to keep their foreign market share, but the globalization of firms' activities may be another important factor in lowering the pass-through.J.

Asymmetric effects of the exchange rate on domestic corporate goods prices

This paper empirically examines whether there are asymmetric effects of the exchange rate on domestic corporate goods prices when the exchange rate is more volatile. To identify different volatilities in the exchange rate, we employ a threshold regression model. In other words, we define exchange rate volatility as a threshold variable. By using monthly data from Japan, we estimate a threshold parameter and calculate its confidence interval by following Hansen (2000). The results substantiate that the degree of exchange rate pass-through to the aggregated corporate goods price index is higher and more gradually adjusted in a higher exchange rate volatility regime. Furthermore, such asymmetric relationships are clearly found in three disaggregated corporate goods prices: petroleum and coal products, nonferrous metals, and chemicals and related products.     

东亚经济体的汇率稳定与出口结构因素

本文从理论视角描述了汇率对出口价格传递机制:在进口的投入品比例高时,或出口产品与外国产品相似、竞争激烈时,出口变化对汇率的变动不敏感。而东亚地区出口结构符合这一特性。对于不可避免地增加汇率弹性的中国,也只有使出口结构高级化,才是人民币升值坚实的基础。     

Implications of Exchange Rate Pass-Through and Nontradable Goods for International Policy Cooperation

This paper investigates the welfare consequences of international policy cooperation by simultaneously introducing the following three elements in a standard two-country general equilibrium model: (i) general degrees of exchange rate pass-through, (ii) nontradable goods and their sector-specific productivity shocks, and (iii) general weights on goods in Cobb–Douglas consumption indices. There are two channels for possible mutual welfare gains from policy cooperation: First, cooperation can compensate for insufficient changes in the terms of trade when the degree of exchange rate pass-through is intermediate. Second, countries can cooperate in reaction to shocks in the nontradable goods sectors. This second channel is revealed by deriving an analytical condition for welfare gains under full pass-through and this condition is characterized by the weights in the consumption indices and the variances of sector-specific productivity shocks. Numerical evaluation demonstrates that when the two countries are symmetric and equal weights on consumption goods are assumed, welfare gains from cooperation increase as symmetric pass-through elasticity increases, which implies that the second channel dominates the first, whose effect on welfare gains is nonmonotonic in pass-through elasticity.     

人民币对美元实际汇率变化:巴拉萨-萨缪尔森效应还是一价定律偏离?

对人民币实际汇率进行分解研究发现,可贸易品与不可贸易品之间的相对价格变动对实际汇率波动的解释能力远小于可贸易品偏离一价定律因素,表明人民币对美元实际汇率变动主要受可贸易品价格波动的影响。进一步放松一价定律假设并在传统的巴萨效应检验模型中加入一价定律偏离因素后,进行回归分析发现,一价定律偏离因素是人民币实际汇率波动的主要影响因素,而巴拉萨-萨缪尔森效应仅在1994年以后的样本区间才显著。本文的研究表明,相对一价定律偏离因素,巴萨效应对实际汇率波动的影响是次要的。     

国内价格的汇率传递性——基于VAR模型的实证研究

本文利用VAR模型研究了我国国内价格的汇率传递性。VAR模型的脉冲反应函数显示,存在人民币汇率对国内价格的不完全传递性,但是,传递弹性极低,进口价格指数的汇率传递弹性要强于消费价格指数的汇率传递弹性,且进口价格指数向消费价格指数传导逐渐衰减。因此,通过汇率升值来抑制通胀效果并不理想,从紧的货币政策才是医治通胀的良药。     

汇率传导、人民币升值与通货膨胀的关联度

经济开放度在汇率传导过程中起着重要作用,考虑经济开放度后,汇率调整对国内通货膨胀的影响显著增强。研究表明,进口依存度与汇率传导效应正相关,金融开放度与汇率传导效应负相关。通过构建模型,进行实证分析,结果显示,我国的原材料购进价格指数、生产者价格指数和居民消费价格指数与进口依存度、金融开放度和人民币汇率波动关系密切。在现阶段的宏观经济形势下,人民币合理适度的升值有助于缓解国内的通货膨胀压力,促进我国经济内外部均衡发展。
