Does Monetary Integration Reduce Exchange Rate Pass‐Through?

There are several theoretical arguments for why the adoption of a common currency (either a currency union or a currency board) may reduce the exchange rate pass‐through (ERPT) to domestic consumer prices. This paper examines a broad panel of 101 countries over the period 1976–2006, using two‐stage instrumental‐variable estimation techniques in order to resolve the potential endogeneity problem. The main result is that ERPT indeed tends to decline in countries participating in a common currency arrangement. In particular, there has been a strong reduction in pass‐through in the member countries of the European Monetary Union (EMU) since the launch of the euro. Currency boards do not appear to be different from currency unions – both reduce the pass‐through from depreciation to inflation. Furthermore, the negative impact of common currencies on ERPT is at work in both high‐income and low‐income countries. Finally, most of the reduction in pass‐through to consumer prices under common currency arrangements happens somewhere along the pricing chain between the border and the supermarket shelf.     

Export Performance,Invoice Currency and Heterogeneous Exchange Rate Pass‐through

Using comprehensive, shipment‐level merchandise trade data for a small, open economy, we examine heterogeneity in exporters' exchange rate pass‐through (ERPT) behaviour. We draw together two recent studies of ERPT, linking invoice currency decisions and firm performance to heterogeneity in ERPT. Like these studies, we find that the short‐run reaction of export unit values to exchange rate fluctuations is significantly related to both invoice currency choice and exporter characteristics when these are analysed separately. However, we then show that when the two factors are jointly accounted for, the role of exporter characteristics largely disappears. That is, some firm types are more inclined to invoice in the producer currency, while others use either the local or a vehicle currency. In the short run, this translates into differences in exchange rate pass‐through because of price rigidity in the invoice currency. Firm characteristics do not have an independent impact on pass‐through beyond their effect on currency composition. Differences across invoice currencies diminish over time, but do not disappear, as prices adjust to reflect bilateral exchange rate movements.     

Testing the asymmetric effects of exchange rate pass‐through in BRICS countries: Does the state of the economy matter?

This paper investigates not only the question of whether there is exchange rate pass‐through (ERPT) but also the extent to which the pass‐through is asymmetric or state‐dependent in the BRICS countries. Using monthly data from 1999:M1 to 2019:M12 and non‐linear smooth transition vector autoregressive (STVAR) model, our results provide evidence of period‐specific ERPT between the upper and lower regime periods, governed by the selected transition variables. The results further suggest that the pass‐through of exchange rate is higher when the economy is experiencing large appreciations and expansions as well as large depreciations and recessions. Theimplication for these findings is that ERPT is strongly affected by the state of the economy.     

Who Gains From Nominal Devaluation? An Empirical Assessment of Euro‐area Exports and Imports

In early 2013, rumours about the euro‐appreciation gained momentum, which may lead to decreases in exports and increases in imports of the member states. Therefore, we investigate the impact of changes in the nominal euro exchange rate vis‐à‐vis major currencies on export and import performance of nine different euro‐area countries. To disentangle the ‘true’ equilibrium elasticities Stein's unbiased risk estimate (SURE) system error correction models (SSECM) are estimated for nominal exchange rate changes versus the rest of the world or other major currencies. To differentiate between price level changes and changes of the nominal exchange rate, a country's export and import equation is estimated using separately the nominal rate and the relative price/unit labour cost as regressors. Results of Wald tests indicate that assuming both variables to have the same influence on exports and imports is misleading. Whether the relative price/unit labour costs elasticities are high or low depends crucially on which indicator is chosen, while the effect of nominal exchange rate changes can be estimated robustly for all countries in the sample. In particular, France and Spain are hit by a euro‐appreciation since their exports are highly exchange rate elastic. However, for France, this effect is at least partly offset by an also negative exchange rate elasticity of imports.     

人民币汇率变动的进口价格传递效应——基于企业类型的实证研究

汇率传递是汇率变动与其经济影响的中间环节。传递弹性在很大程度上决定了汇率变动经济影响的大小。利用分布滞后模型、协整、向量自回归等方法,研究本国企业和外资企业的进口价格对人民币汇率变动的传递效应,结果显示,外资企业进口价格的传递弹性明显大于本国企业,人民币升值对外资企业进口的促进作用较明显。由于外资企业进口的很大部分是用于加工贸易,其较高的传递弹性会在一定程度上抵消人民币升值对出口的负面影响。     

Retailers and Consumers: The Pass‐through of Import Price Changes

In this paper, we estimate pass‐through rates of import price changes to retail prices across retailers and consumers for apparel purchases in Germany for the period of 2000–07. We find that high‐price retailers do not pass through changes in the import price. Pass‐through rates for low‐price retailers are 53 per cent within three months. Consequently, pass‐through rates for low‐income households are 58 per cent, significantly larger than those for high‐income households. We then present one possible explanation for these observations in a theoretical model with endogenous vertical product differentiation due to bundling an ex ante homogeneous import goods with services. Following an import price change, retailers who sell a cheaper unbundled product change prices to a greater extent than retailers who sell a higher‐priced bundle of product and service.     

Exchange‐rate Misalignments in Duopoly: The Case of Airbus and Boeing

We examine the effect of exchange‐rate misalignments on competition in the market for large commercial aircraft. This market is a duopoly where players compete in dollar‐denominated prices while one of them, Airbus, incurs a large fraction of its costs in euro. We estimate price elasticities for big aircraft, and construct a simulation model to investigate how companies adjust their prices to deal with the effects of a temporary misalignment and how this affects profit margins and volumes. We conclude that, due to the duopolistic nature of the aircraft market, Airbus will pass only a small part of the exchange‐rate fluctuations on to customers. Moreover, due to features specific to the aircraft industry, such as customer switching costs and learning‐by‐doing, even a temporary departure of the exchange rate from its long‐run equilibrium level may have permanent effects on the industry.     

BRICS: How important is the exchange rate pass-through?

This paper analyses the exchange rate pass-through (ERPT) into domestic consumer prices in BRICS (Brazil, Russia, India, China and South Africa) countries from mid-1990s onwards by using three different econometric approaches (i.e., the single equation approach, the VAR approach and the time-varying parameter approach). It is also studied the role of macroeconomic determinants in ERPT. Our results suggest that (a) ERPT is higher for the emerging markets with mostly floating exchange rates (Brazil, Russia and South Africa) than for the other BRICS countries; (b) exchange rate explains, on average, around the 40% of the price variance for Brazil, Russia and South Africa; and (c) inflation volatility, exchange rate volatility and openness seem to be the key macroeconomic determinants in BRICS countries.     

Does US quantitative easing affect exchange rate pass‐through in China?

In this paper, we show theoretically and empirically that the US quantitative easing (QE ) policy results in lower exchange rate pass‐through into the destination prices of Chinese exporters. In addition, the more the exchange rate in the export destination appreciates than the Chinese yuan, the stronger this effect becomes. Our model combines various marginal effects of QE policy on the destinations of Chinese exporters and variable markups of export firms due to strategic complementarities. The model predicts that the impact of US QE policy on the pass‐through of Chinese exporters depends on its spillover on the exchange rate between China and the export destination of different firms. We provide strong support for the model predictions using Chinese firm‐product‐level data with information on export destinations. The baseline result and the heterogeneity we find in the response of exchange rate pass‐through of Chinese exporters to US QE policy remain robust to alternative measures of samples and controls.

Has exchange rate pass-through really declined? Evidence from Canada

Several empirical studies suggest that exchange rate pass-through has declined in recent years among industrialized countries. Results for Canada also indicate that import and consumer prices have become less responsive to exchange-rate movements in the 1990s. These findings are based on reduced-form regressions that are typically motivated by partial-equilibrium models of pricing. This paper uses instead a structural, general-equilibrium approach to test the premise that exchange rate pass-through has decreased in Canada. Our approach consists in estimating a dynamic stochastic general-equilibrium model for Canada over two sub-samples, which cover the periods before and after the adoption of inflation targeting by the Bank of Canada. We then use impulse-response analysis to assess the stability of exchange rate pass-through across the two sub-samples. Our results indicate that pass-through to Canadian import prices has been rather stable, while pass-through to Canadian consumer prices has declined in recent years. Counterfactual experiments reveal that the change in monetary policy regime is largely responsible for this decline.     

Foreign Exchange Reserves and Import Demand: Evidence from Latin America

This paper investigates the impact of foreign reserves, domestic real income and relative import prices on import demand for seven Latin American countries. We differentiate empirically between the short‐run and long‐run impact of reserves, income and prices on imports. The paper has three main results. First, we show that there exists a unique long‐run relationship among real imports, real income, relative import prices and real foreign exchange reserves for all seven countries. Second, we find that increases in foreign exchange reserves exert a significant positive effect on import demand in both the long run and the short run in all countries. However, the economic impact of foreign exchange reserves is rather small. Finally, we find that the long‐ and short‐run impact of real domestic income on import demand is positive as well, while the effect of relative prices is negative.     

Import Churning and Export Performance of Multi‐product Firms

This paper analyses the impact of churning in the imported varieties of capital and intermediate inputs on firm export scope and productivity. Using detailed data on imports and exports at the firm‐product‐market level, we document substantial churning in both imports and exports for Slovenian manufacturing firms in the period 1994–2008. On average, a firm changes about one‐quarter of imported and exported product‐markets every year, while gross churning in terms of added and dropped product‐markets is almost three times higher. A substantial share of this product churning is due to simultaneous imports and exports of firms in identical varieties within the same CN‐8 product code (so called pass‐on‐trade). We find that churning in imported varieties is far more important than reduction in tariffs or declines in import prices for firms’ productivity growth and increased export product scope. We also find gross churning has a bigger impact on firm productivity improvements by a factor of more than 10 in comparison with net churning. Both adding and dropping of imported input varieties thus seem to be of utmost importance for firms aiming to optimise their input mix towards their most valuable inputs. These effects are further enhanced when excluding simultaneous trade in identical varieties, suggesting that pass‐on‐trade has less favourable effects on firms’ long‐run performance than regular trade.     

Does Euro or Dollar Pegging Impact the Real Exchange Rate? The Case of Oil and Commodity Currencies

The aim of this paper is to investigate the equilibrium exchange rates for commodity and oil currencies as well as the discrepancies of their observed exchange rates to these equilibriums. To this end, first, we estimate a long‐term relationship between the real effective exchange rate and economic fundamentals, including the commodity terms of trade. The estimation relies on panel cointegration techniques and covers annual data from 1980 to 2007. Our results show that real exchange rates co‐move with commodity prices in the long run and respond to oil price somewhat less than to commodity prices. Second, we assess the degree of misalignment of these currencies, as the gap between their observed exchange rate and the estimated equilibrium exchange rate. We show that these misalignments are not significantly related to the exchange rate regimes adopted by the countries, either pegged or floating. However, for pegged currencies, the size of misalignments significantly depends on the anchor currency, either the euro or the dollar. A comparison of misalignments of pegged commodity and oil currencies across different periods confirms these results: during periods of dollar (euro) overvaluation, currencies pegged to the dollar (euro) tend to be overvalued; the reverse being true when the dollar (euro) is undervalued. Consequently, pegged currencies are often driven away from their equilibria by wild fluctuations in the key currencies, on which they are anchored.     

Towards adopting inflation targeting: The credibility and limitations of monetary policy under the fixed exchange system—the case of Jordan

In this paper, the interest rate pass‐through is examined within its intermediate lag of action to shed light on the credibility of monetary policy in Jordan, where the reputation of low inflation is imported through a fixed exchange rate system to the US dollar. We use time series methods which allow us to test for asymmetric adjustment. The results are compared to that of two inflation targeting countries at time proceeding building the credibility of price stability domestically: New Zealand and the UK. The empirical findings suggest that the interest rate pass‐through in Jordan is weak and slow. In addition, our results indicate the existence of non‐competitive pricing behaviour in the market. Comparing the results to the two inflation targeters, the study suggests that Jordan needs to move to a more resilient exchange rate arrangement.     

Price developments after a nominal shock: Benford's Law and psychological pricing after the euro introduction

Retail managers use psychological pricing to make the prices of goods appear to be just below a round number. The euro introduction in 2002, with its various exchange rates, distorted existing nominal price patterns while at the same time retaining real prices. We studied consumer prices before and after the introduction of the euro by using Benford's Law as a benchmark for price adjustments. Results indicate the usefulness of this benchmark for detecting irregularities in prices, and a clear trend towards psychological pricing after the nominal shock of the euro introduction. In addition, the tendency towards psychological prices results in different inflation rates in dependence of the price pattern.     

石油净进口大国利率与油价对净出口的影响

传统贸易理论在研究影响一国净出口因素时只考虑了汇率和收入水平,本文在此基础上加入了利率和油价因素,并以美、中、日三个石油净进口大国为例进行了实证分析,结果表明利率上升减少投资需求,降低国内物价水平,增强出口商品价格竞争力,使出口增加,进口减少;油价上涨,石油进口支出增加,一国进口总额增加。实证和理论分析结果基本相符,即净出口与利率呈正向关系,与油价呈负向关系。     

STOLPER–SAMUELSON REVISITED: TRADE AND DISTRIBUTION WITH OLIGOPOLISTIC PROFITS

This paper investigates the distributional impact of international trade when goods markets are oligopolistic and firms partially pass‐through changes in tariffs into prices and factor costs for differentiated products. Trade liberalization raises mark‐ups and profit shares in the export industry and lowers them in the import‐competing industry, while Stolper–Samuelson effects on real prices of primary factors are attenuated or possibly reversed. An extended model shows how ‘offshoring’ (trade in intermediate goods) can potentially increase mark‐ups for oligopolistic producers of final goods. The analysis illuminates why business interests generally support trade liberalization policies today, regardless of their countries' factor abundance.     

局部地区冲突冲击了中国石油进口吗

文章利用1992～2018年中国从80个国家石油进口的非平衡面板数据,实证考察出口国发生局部地区冲突对中国石油进口的影响,并对其异质性特征和可能的影响机制予以识别。研究表明,出口国局部地区冲突会给中国石油进口带来显著的负向冲击,该影响主要是局部地区冲突引起出口国石油产量下降所致。局部地区冲突不会通过国际油价和中国石油对外直接投资影响中国石油进口。石油资源禀赋和"一带一路"倡议能够在一定程度上对冲局部冲突对中国石油进口的负向影响。局部地区冲突对中国石油进口的冲击具有明显的阶段性特征,并且随着中国石油进口依存度的攀升逐渐增强。在当前国际油市深度调整的现实背景下,该研究为深刻认识一系列国际重大突发事件对中国石油进口的影响、保障中国石油进口安全提供了科学借鉴。
