美元汇率对美国进出口商品价格传递率的实证分析

本文实证分析了美元汇率按美国总进出口价格、分段进出口价格、分类商品进出口价格的传递率。实证结果表明,无论美元升值还是贬值,美国的进出口价格指数都会下降,而且美国出口价格的传递率比同期进口价格的传递率要小得多,升值期的传递率也比贬值期的传递率要小;美元升值比贬值对美国经常账户赤字的纠正更有利。因此,建议美国实行美元适度升值的政策,而且要结合其他政策才能改善其巨额经常账户赤字。     

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.     

Markups and export-pricing strategies

We analyze empirically export-price strategies across export destinations using detailed firm-product data. Most recent studies using disaggregated data to investigate why firms charge different prices for the same product on different markets focus on the cost component of prices and neglect the markup component. In this paper, we concentrate on the markup component and examine how variations in firms’ export prices may reflect price discrimination by comparing the markup of firms with different pricing strategies. We make use of detailed firm-level data for exporting firms in the Swedish food sector consisting of both manufacturing and intermediary trading firms. The paper documents the export-price variations within the two sub-sectors and explores how different price strategies correlate with markups. The results offer new information beyond the fact that exporters tend to have a higher markup. In particular, we find that firms in the food-processing sector with a greater ability to discriminate across markets mark their products up even more. This result points to the importance of underlying firm decisions in order to explain differences in export premiums across firms. In addition, the results reveal that markups are a complex function of firm and destination characteristics, and that the relationship between markups and pricing strategies in the manufacturing sector is not necessarily observed in other sectors of the supply chain.     

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.

COMMODITY PRICE SHOCKS AND THE AUSTRALIAN ECONOMY SINCE FEDERATION*

Australia has experienced frequent and large commodity export price shocks similar to commodity exporters in Asia, Africa, and Latin America, but this price volatility has had much more modest impact on economic performance. Why? This paper explores Australian terms of trade volatility since 1901. It identifies two major price shock episodes before the recent mining‐led boom and bust. It assesses their relative magnitude, their impact on de‐industrialisation and distribution during the booms, and the labour market and policy responses to the shocks. Australia has indeed responded differently to volatile commodity prices than have other commodity exporters.     

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.     

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。     

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.     

THE ECONOMICS OF IMPORT PARITY PRICING: A PEDAGOGICAL NOTE

This paper demonstrates that pricing to import parity is not necessarily prima facie evidence of the exercise of market power. It is shown that in the presence of imports both market structures, perfect competition and monopoly, can price to import parity. If markets can be segmented enabling the firm to discriminate between the export and domestic market it is shown that the imperfectly competitive firm can differentially price. Furthermore, as the number of domestic firms is increased, and if these firms are able to segment the market, the differential between domestic and foreign prices is reduced. The import parity price may or may not be charged in the domestic market. A measure of the exercise of market power is therefore the differential between export parity and the domestic price.     

How responsive is Chinese export supply to market signals?

This paper studies the behavior of Chinese exporters from the mid-1980s through 2001. Extensive quarterly data on values and quantities of major export products have been taken from Chinese customs statistics to form a panel data set and aggregate export unit price and volume indices. The data are used to estimate export supply price elasticities, including by industry groups. The overall results indicate an increase in the responsiveness of export supply to market price signals in more recent periods following reforms.     

The relative importance of foreign and domestic shocks to output and prices in Mexico and Colombia

The Relative Importance of Foreign and Domestic Shocks to Output and Prices in Mexico and Colombia. — This paper utilizes structural VARs to evaluate the relative importance of foreign and domestic sources of variation in output and prices in Mexico and Colombia. The real exchange rate and commodity export price have a large impact on both output and prices in Mexico, while in Colombia their effects are smaller. U. S. output and interest rates are found to play a significant role in determining output in Mexico and Colombia. For Mexico, external variables are found to be of much greater importance in the oil-exporting years after 1978 as compared to the 1960s.     

Core Import Price Inflation in the United States

The cross-section distribution of U.S. import prices exhibits some of the fat-tailed characteristics that are well documented for the cross-section distribution of U.S. consumer prices. This suggests that limited-influence estimators of core import price inflation might outperform headline or traditional measures of core import price inflation. We examine whether limited influence estimators of core import price inflation help forecast overall import price inflation. They do not. However, limited influence estimators of core import price inflation do seem to have some predictive power for headline consumer price inflation in the medium term.     

Commodity prices and the macroeconomy: An extended dependent economy approach

This paper proposes a straightforward model for analysing the impact of export commodity price fluctuations on open macroeconomies with particular reference to Australia and New Zealand, major commodity exporters in the Asian region. It extends the dependent economy approach, first by re-specifying goods and services production as either exportable, importable or non-tradable, and second by adding a monetary sector to highlight key linkages between commodity prices, the exchange rate, price level, national output and trade account. The framework sheds new light on the phenomenon of ‘commodity currencies’, how exchange rate movements shield national output from terms of trade shocks, the importance of economic openness in this process, and the significance for monetary and exchange rate policy of short term, versus sustained, commodity price movements.     

Relative export prices and firm size in imperfect markets

This paper contributes to the rising field in international trade and industrial organization. A vast sample of Italian micro data is used to study the behavior of relative export prices in imperfect markets. It is shown that relative export prices, the relation of prices a firm charges on export and domestic markets, are, in general, downward biased. Moreover, relative export prices depend negatively on firm size and market concentration, but positively on the average export share of the industry. This indicates that markets are segmented and firms are able to discriminate prices.     

An empirical analysis of the unit labor cost-product price relation in the U.S. economy

This article tests for cointegration between unit labor costs and the level of product prices in four sectors of the U.S. economy: the aggregate business sector, the nonfinancial corporate sector, durable manufacturing, and nondurable manufacturing. A finding of cointegration for most specifications supports the existence of long-run labor market equilibrium for producers and suggests estimation of error-correction models to examine the dynamic relationships. In every sector except nondurable manufacturing, error-correction model estimates indicate there is a mutual feedback relationship between unit labor costs and prices. Controlling for deviations from full employment, oil price shocks, and the Nixon wage and price controls, the results also provide evidence of significant nominal wage indexation in U.S. labor markets. Throughout the economy there appears to exist both effective neoclassical wage and price adjustment mechanisms to maintain labor market equilibrium and short-run rigidities which may contribute to deviations from full employment outcomes.     

Oil and gold price dynamics in a multivariate cointegration framework

This study delivers further insights into oil and gold price dynamics and their relation to U.S. prices and the dollar exchange rate. Previous studies have frequently analyzed this issue regarding the price either of gold or of oil; however, the role of both quantities has not been analyzed simultaneously in a broader context. To tackle this caveat, we use monthly data for the nominal effective dollar exchange rate, oil, gold and U.S. prices from 1976:01 to 2011:11. We carefully analyze the long-run as well as the short-run dynamics and the long-run impact in terms of shocks, applying a cointegrated VAR model. The main conclusion we reach is that although gold and oil are both important commodities, their economic impact in terms of their shocks differs significantly. In the long-run, both quantities seem to be positively related and shocks to the gold price drive the system. In addition, the gold-oil spread is positively related to U.S. consumer prices, which implies a stronger relationship of consumer prices to the former.     

Exchange rates and the trade balance: the case of Singapore 1970 to 1996

The purpose of this paper is to examine the relationship between the real trade balance and the real exchange rate for bilateral trade in merchandise goods between Singapore and the USA on a quarterly basis over the period 1970 to 1996 using the partial reduced form model of Rose and Yellen (1989). We also hope to shed further light on what has become known as the ‘Singapore export puzzle’: the observation that, despite periods of rapid nominal and real appreciation of the Singapore dollar, export growth in aggregate has remained buoyant.Our findings suggest that the real exchange rate does not have a significant impact on the real bilateral trade balance for Singapore and the USA, thus confirming previous work which finds a weak relationship between changes in the exchange rate and changes in export and import prices and volumes for Singapore. We also found little evidence of a J-curve effect. Although positive coefficients linking real exports with lagged values of the real exchange rate might be indicative of ‘small country’ pricing by exporters in U.S. dollars, it is not clear that this is masking J-curve effects from an initial rise in import values as the home currency depreciates.     

Regional Comparisons,Spatial Aggregation,and Asymmetry of Price Pass-Through in U.S. Gasoline Markets

Spot to retail price pass-through behavior of the U.S. gasoline market was investigated at the national and regional levels, using weekly wholesale and retail motor gasoline prices from January 2000 to the present. Asymmetric pass-through was found across all regions, with faster pass-through when prices are rising. Pass-through patterns, in terms of speed and time for completion, were found to vary from region to region. Spatial aggregation was investigated at the national level and the East Coast with the aggregated cumulative pass-through being greater than the volume-weighted regional pass-through when spot prices increase. These results are useful to the petroleum industry, consumers, and policy makers by providing a basis to estimate the retail price effects that result from a change in spot price.     

How Did the Dollar Peg Fail in Asia?

In this paper, we have constructed a theoretical model in which the Asian firm maximizes its profit, competing with the Japanese and the U.S. firms in their markets. The duopoly model is used to determine export prices and volumes in response to the exchange rate fluctuations vis-à-vis the Japanese yen and the U.S. dollar. Then, the optimal basket weight that would minimize the fluctuation of the growth rate of trade balance was derived. These are the novel features of our model. The export price equation and export volume equation are estimated for several Asian countries for the sample period from 1981 to 1996. Results are generally reasonable. The optimal currency weights for the yen and the U.S. dollar are derived and compared with actual weights that had been adopted before the currency crisis of 1997. For all countries in the sample, it is shown that the optimal weight of the yen is significantly higher than the actual weight.J. Japan. Int. Econ.,Dec. 1998,12(4), pp. 256–304.
