我国出口汇率传递的非对称性:来自中日贸易的证据

文章扩展了Yang（2007）的厂商定价模型，对汇率传递非对称性、特点和成立条件进行理论分析，发现对称传递需要满足严格的条件，而现实中更常见的是非对称汇率传递。在一定条件下，商品需求弹性越大，越可能呈现出口国货币贬值传递率高而升值传递率低的特点。利用2000年1月至2011年12月我国出口日本的966种商品价格数据，发现汇率波动向价格传递具有非对称性：（1）人民币升值时，日元价格上涨较少；而贬值时，价格下降较多。我国出口商品的需求弹性较大，在日本市场上面对的是一个强竞争结构。（2）若月度升值超过一定幅度（测算约为2.43%），传递率又会有所上升，说明尽管日元价格易跌难涨，但在升值导致成本上涨较多、明显挤压利润时，厂商不得不适当提高日元售价。采用2000年至2018年9月日本从中国进口单位价值指数进行稳健性检验，得出类似结论。现阶段稳定的人民币名义汇率对我国出口企业是更为有利的。     

人民币汇率变动的进口价格传递效应——基于贸易方式的实证研究

汇率传递是汇率变动与其经济影响的中间环节,进口价格传递弹性在很大程度上决定了汇率变动对进口的影响大小。本文利用分布滞后模型、协整、向量自回归等方法,研究了三种主要贸易方式的进口价格对人民币汇率变动的传递。结果显示,进料加工进口价格的传递弹性要大于一般贸易。在其他条件不变的情形下,人民币升值对进料加工进口的促进作用明显大于一般贸易;而来料加工装配进口受人民币升值影响比较有限,更主要受世界需求、国内劳动力成本等影响。     

Does quality differentiation matter in exporters' pricing behaviour? Comparing China and India

The product quality dimension has been rarely mentioned as a factor explaining the heterogeneous pricing strategies of exporters. This could underestimate the degree of mark-up adjustment and the extent of incomplete exchange rate pass-through (ERPT) at a disaggregated level across products and destination markets. This paper investigates the role of quality differentiation in price discrimination using data for China and India's exports disaggregated at the 6-digit product level across destination markets. The paper adopts an empirical approach that incorporates gravity model explanatory factors and allows disentangling the effect of quality on trade prices and volumes from that of other sources of price variation. After excluding short duration export spells, China's export prices denominated in foreign currency terms increase with the yuan's depreciation, implying an increase in exporters' mark-ups, but they decrease as expected in the case of India. However, mark-up increases decline with product quality and destination market income, as the elasticity of demand perceived by exporters increases. These findings remain robust to different measures of quality, samples, specifications, and to the potential endogeneity of quality.     

A Comparative Analysis of Export Price Pass-through in Three Open Asian Economies: Korea,Singapore and Thailand

Abstract

The degree of exchange rate pass-through is of paramount importance to small and open economies as it has a direct impact on domestic inflation as well as the effectiveness of exchange rate as an adjustment tool. High exchange rate pass-through (ERPT) is often cited as a reason for a “fear of floating”. This article analyzes the degree of ERPT into the export prices of three Asian economies—Korea, Thailand and Singapore for the period 1980: Q1–2006: Q4 using both US dollar bilateral rates as well as nominal effective exchange rates. The study also examines whether there are asymmetries in ERPT between exchange rate appreciation and depreciation.     

Exchange Rate and Inflation Dynamics in a Resource Rich Setting: The Case of Zambia

This paper investigates the relationship between copper prices, the exchange rate and consumer price inflation in Zambia using a structural vector autoregression with quarterly data for 1995–2014 and a combination of sign and zero restrictions to identify relevant global and domestic shocks. The paper makes two contributions. First, it provides new measures of exchange rate pass through (ERPT), based on less restrictive assumptions than previous estimates, to show how changes in the value of the kwacha are reflected in changes in consumer prices (distinguishing food and non‐food inflation). Second, the ERPT is disaggregated to demonstrate that measured ERPT depends on the nature of the shock, with implications for policy responses. Although the price of copper is the most important driver of the exchange rate, the fluctuations it caused are associated with a low pass‐through of about 7% (consistent with a period of relatively low inflation). Exchange rate fluctuations caused by monetary shocks, in contrast, come with a pass‐through of up to 25% (and even more for food prices). A fast response by monetary authorities can mitigate the adverse effects of exchange rate shocks.     

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 PASS‐THROUGH TO IMPORT PRICES IN SOUTH AFRICA: IS THERE ASYMMETRY?1

This paper examines the magnitude and speed of exchange rate pass‐through (ERPT) to import prices in South Africa. It further explores whether the direction and size of changes in the exchange rate have different pass‐through effects on import prices, i.e. whether the exchange rate pass‐through is symmetric or asymmetric. The findings of the study suggest that ERPT in South Africa is incomplete but relatively high. Furthermore, ERPT is found to be higher in periods of rand depreciation than appreciation, which supports the binding quantity constraint theory. There is also evidence to suggest that pass‐through is slightly higher in periods of small changes than large changes in the exchange rate in harmony with the menu cost theory when the invoices are denominated in the exporters' currency.     

Revisiting the Exchange Rate Pass‐Through to Inflation in Africa’s Two Largest Economies: Nigeria and South Africa

This paper revisits the exchange rate pass‐through (ERPT) to inflation in Nigeria and South Africa by incorporating structural breaks and using time series variables, namely the consumer price index, nominal effective exchange rate, gross domestic product, and crude oil price. Based on the Maki cointegration test and a flexible estimation approach of the Autoregressive Distributed Lag (ARDL) model, our empirical evidence suggests that the long‐ and short‐run ERPT to inflation is complete for Nigeria, while for South Africa it is incomplete both in the long run and short run. This result indicates that prices are stickier in South Africa compared to Nigeria. The comparison between Nigeria and South Africa confirms the role of inflation targeting and central bank credibility on the ERPT. The results divulge further that output growth in Nigeria increases inflation in the long run while it is anti‐inflationary in the short run. For South Africa, the effect of output growth is negatively insignificant. In addition, the long‐run effect of oil price is negative and significant for Nigeria, while for South Africa the short‐run effect of oil price is positive and significant. Therefore, the findings of this paper will assist the monetary authorities to achieve monetary policy objectives.     

Portfolio modelling and growth in open economies

The standard BRANSON model is modified in a way which allows one to focus on the short term dynamics of foreign bonds markets, the money market and the stock market—or alternatively the oil market. This allows us to explain the dynamics of the exchange rate and the oil price within a portfolio choice model; also we identify critical expectation dynamics in a more conventional pricing approach to the oil market—expectations determine whether or not the oil market equilibrium is compatible with a stationary price or with sustained oil price inflation. Moreover, a straightforward innovative way to combine a portfolio approach with a growth model is developed. New results are obtained—through multiplier analysis—about the long term effects of changes in the savings rate, the process innovation rate, the product innovation variable and the money supply on the exchange rate and the stock market price; this raises many empirical issues. Finally, the analysis presented sheds new light on the global asset price dynamics in the context of the banking crisis.

A Survey of Exchange Rate Pass-Through in Asia

Exchange rate pass-through (ERPT) refers to the transmission of exchange-rate changes into import (export) prices of goods in the destination-market currency as well as into aggregate domestic prices. This paper examines the analytical and empirical literature on ERPT with particular reference to Asia. It is generally believed that Asian economies are potentially susceptible to ERPT into domestic inflation since they are highly trade-dependent. Particular attention is paid to production sharing—a key characteristic of Asian trade—and its implications for ERPT.

Has pass-through to export prices risen? Evidence for Japan

This paper investigates the exchange rate response of Japanese export prices over the period 1980 through 2007 using sector-specific measures of the yen’s value relative to invoicing currencies. It finds a significant increase in the response of total export prices to the yen in the late 1990s. The rise in the total export price response is traced to increases in the exchange rate response of two key export sectors. These findings for Japanese exports are consistent with the documented decline in pass-through to OECD import prices and suggest the latter could originate with changes in export pricing behavior.     

The Impact of Korea's Exchange Rate Volatility on Korean Trade

This study uses a GARCH-in-mean model to analyse the impact of Korea's nominal exchange rate volatility on exports and export prices over the current flexible-rate period. The volatility of Korea's won increases the exchange risk of exporters and leads to changes in export volume and price. This paper provides some evidence that nominal exchange rate volatility has had a statistically significant impact on real exports over the current floating-rate period. We show that persistence-in-variance of exchange rates affects the market for exports in Korea. An important result is that the effect of exchange rate volatility on trade variables is shown to be significant. We find that the GARCH conditional variance has a statistically significant impact on the reduced form equations. The magnitude of the effect is generally stronger for export quantities than prices. This result is contradicts that of Kroner and Lastrapes's analysis. This is explained by the fact that Korean exporters choose the strategy of pricing to maintain market share instead of adjusting export prices to reflect exchange rate changes, even when this cuts profit margins.

Exchange rate pass-through in Korea and Thailand: Trends and determinants

An important but age-old transmission channel of global factors into domestic prices is via exchange rate movements. This paper examines the extent and evolution of exchange rate pass-through (ERPT) into Korea's and Thailand's consumer and import prices at the aggregate level for the period over the last two decades. We find that ERPT appears to be consistently higher for Thailand compared to Korea; while for both nations ERPT of their respective bilateral rates with respect to the US dollar is higher than with respect to the Japanese yen. The paper also investigates if and how ERPT has changed over time, especially during and after the currency crisis period of 1997–1998, as well as its macroeconomic determinants.     

Firms’ heterogeneity,demand accumulating,and exchange rate pass-through

In this article, we study how the export behaviors of new and incumbent exporters differentially respond to exchange rate shocks. We establish a dynamic model, in which new exporters strategically charge a lower price than incumbent exporters to grow their customer base and increase future sales. The model predicts that new exporters adjust their prices more aggressively relative to their incumbent counterparts in response to exchange rate fluctuations. Using a transaction-level data set containing all Chinese exporters during the 2000–2009 period, we find supporting evidence for the model's predictions: new exporters adjust their price 1.5 times more than incumbent exporters. This, in turn, results in export quantities being less responsive to exchange rate shocks among new exporters. The result holds for a series of robustness checks. The findings imply that there are different degrees of exchange rate pass-through among new and incumbent exporters.     

出口退税政策对高耗能产品出口的控制效应研究——基于中国钢材出口经验证据

钢铁行业实施的是差别退税制度。文章通过建立PVAR(面板向量自回归)模型,使用脉冲响应函数分析方法,测度出口退税率的调整对高、中、低能耗钢材产品出口量及出口价格动态影响的异同,以此分析出口退税政策对高能耗产品出口的控制效应。实证结果表明:出口退税率的提高能刺激出口,高能耗产品的出口对出口退税率的变化最敏感。与出口退税率的影响相比,出口商品价格对出口量的影响要小得多,但同样地,高能耗产品的出口对出口商品价格变化最敏感。最后,出口退税政策的调整从总体上对出口商品价格的影响不大,但出口退税率上升将导致高能耗产品更有价格优势。     

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。     

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。     

Pricing to Market： Chinese Export Pricing to the USA after the Peg

In July 2005, the Chinese Government unpegged the RMB from the US dollar. As the RMB has followed a remarkably predictable appreciation over time, I examine the price of Chinese exports to the USA after unpegging the exchange rate. Results suggest that the Chinese industries with greater import market share were able to raise their prices after the removal of the pegged exchange rate regime; however, over time there is a significant deflationary trend. Chinese export prices tended to decrease under an unanticipated RMB appreciation; this effect was more pronounced for industries with more pricing flexibility. This suggests that Chinese exporters are consistently ＂pricing to market＂ and thus creating a significant foreign exchange policy implication. Specifically, a more flexible exchange rate regime will likely have little impact on the prices of Chinese exports to the USA but might increase the profit volatility of Chinese firms.
