Exchange Rate Pass-Through in a Competitive Model of Pricing-to-Market

This paper extends the Mussa and Rosen (1978) model of quality pricing under perfect competition. Exporters sell goods of different qualities to consumers who have heterogeneous preferences for quality. Production is subject to decreasing returns to scale and, therefore, supply and the toughness of competition react to cost changes brought about by exchange rate fluctuations. First, we predict that exchange rate shocks are imperfectly passed through into prices. Second, prices of low-quality goods are more sensitive to exchange rate shocks than prices of high-quality goods. Third, in response to an exchange rate appreciation, the composition of exports shifts toward higher quality and more expensive goods. We test these predictions using highly disaggregated price and quantity U.S. import data and find only weak empirical evidence in support of our theory.     

U.S. real exchange rate fluctuations and relative price fluctuations

Traditional theory attributes fluctuations in real exchange rates to changes in the relative price of nontraded goods. This paper studies the relation between the United States’ bilateral real exchange rate and the associated bilateral relative price of nontraded goods for five of its most important trade relationships. We find that this relation depends crucially on the choice of price series used to measure relative prices and on the choice of trade partner. The relation is stronger when we measure relative prices using producer prices rather than consumer prices. The relation is stronger the more important is the trade relationship between the United States and a trade partner. Even in cases where there is a strong relation between the real exchange rate and the relative price of nontraded goods, however, a large fraction of real exchange rate fluctuations is due to deviations from the law of one price for traded goods.     

中美双边汇率对美国消费价格传递效应的实证研究

人民币升值的价格传递效果是近年来的一个研究热点。已有学者利用人民币汇率变动与关国对我国进口价格指数等数据进行研究,得出了人民币汇率变动的价格传递极低的结论。本文选择美国与我国贸易品相关性较高的消费品价格指数,利用2005年7月至2008年10月之间的月度数据,采用Johsen＆Juselius协整检验、误差修正模型分析汇改以来人民币汇率升值期间中关双边名义汇率变动的价格传递效应。研究发现中关双边名义汇率波动对美国消费物价的影响是显著的,长短期传递系数分别为O．1871、0．1917,并在此研究中得到几点政策启示。     

The effect of low-wage import competition on U.S. inflationary pressure

The effect of import competition from low-wage countries on U.S. inflationary pressure is estimated using a new methodology that identifies the causal response of prices to comparative advantage-induced supply shocks in these nations. The results of a panel covering 325 manufacturing industries from 1997 to 2006 show that imports from nine low-wage countries are associated with strong downward pressure on prices. When these nations capture a 1% share of the U.S. sector, the sector's producer prices decrease by 2.35%. Because import competition also influences the skewness of the distribution of price changes, it is likely to have impacted U.S. equilibrium inflation.     

U.S. Monetary Regimes and Optimal Monetary Policy in the Euro Area

Monetary policy in the United States has been documented to have switched from reacting weakly to inflation fluctuations during the 1970s, to fighting inflation aggressively from the early 1980s onward. In this paper, I analyze the impact of the U.S. monetary policy regime switches on the Eurozone. I construct a New Keynesian two‐country model where foreign (U.S.) monetary policy switches regimes over time. I estimate the model for the U.S. and the Euro Area using quarterly data and find that the United States has switched between those two regimes, in line with existing evidence. I show that foreign regime switches affect home (Eurozone) inflation and output volatility and their responses to shocks, substantially, as long as the home central bank commits to a time‐invariant interest rate rule reacting to domestic conditions only. Optimal policy in the home country instead requires that the home central bank reacts strongly to domestic producer‐price inflation and to international variables, such as imported goods relative prices. In fact, I show that currency misalignments and relative prices play a crucial role in the transmission of foreign monetary policy regime switches internationally. Interestingly, I show that only marginal gains arise for the Euro Area when the European Central Bank (ECB) adjusts its policy according to the monetary regime in the United States. Thus, a simple time‐invariant monetary policy rule with a strong reaction to Producer Price Index (PPI) inflation and relative prices is enough to counteract the effects of monetary policy switches in the United States.     

Monetary union, price level convergence, and inflation: How close is Europe to the USA?

The pattern of price dispersion across European and US cities from 1990 to 2004 is documented. There is a striking decline in dispersion for traded goods prices in Europe, most of which took place prior to the launch of the euro. Dispersion in the euro area is now quite close to that of the USA. This evidence provides useful facts for future work assessing the importance of various developments in Europe: harmonization of tax rates, convergence of incomes and labor costs, liberalization of trade and factor markets, and increased coherence of monetary policy.     

Asset Prices,News Shocks,and the Trade Balance

We analyze the relationship between asset prices and the trade balance estimating a Bayesian VAR for a broad set of 38 industrialized and emerging market countries. To derive model‐based identifying restrictions, we model asset price shocks as news shocks about future productivity in a two‐country dynamic stochastic general equilibrium model. Such shocks are found to exert sizable effects on the trade balance. Moreover, the effects are highly heterogeneous across countries. For instance, following a news shock that implies on impact a 10% increase in domestic equity prices relative to the rest of the world, the U.S. trade balance will worsen by up to 1.0 percentage points, but much less so for most other economies. We find that this heterogeneity appears to be linked to the financial market depth and equity home bias of countries. Moreover, the channels via wealth effects and via the real exchange rate are important for understanding the heterogeneity in the transmission.     

The Age of the Dragon: The Effect of Imports from China on Firm‐Level Prices

We analyze the impact of increased import penetration from China on the dynamics of firm‐level output prices in Italy. Accounting for potential endogeneity biases we find a significant and negative causal relationship: a 0.1 percentage point higher Chinese import penetration restrains price growth by 0.17 percentage points per year. This relationship reflects a procompetitive effect induced by cheaper imports, and, thanks to the firm‐level dimension of our data, we show that it is driven by low‐productivity firms within less skill‐intensive sectors. Finally, we show that Chinese import competition also had a dampening effect on Italian overall inflation.     

Trade integration, competition, and the decline in exchange-rate pass-through

Over the past 20 years, U.S. import prices have become less responsive to the exchange rate. We propose that a significant portion of this decline is a result of increased trade integration. To illustrate this effect, we develop an open economy DGE model featuring demand curves with variable elasticities so that a firm's pricing decision depends on its competitors’ prices. As a result, a foreign exporter finds it optimal to vary its markup in response to shocks that change the exchange rate, insulating import prices from exchange rate movements. With increased trade integration, exporters have become more responsive to the prices of their competitors, explaining a sizeable portion of the observed decline in the sensitivity of U.S import prices to the exchange rate.     

Multiproduct firms and price-setting: Theory and evidence from U.S. producer prices

Using micro-data on U.S. producer prices, we establish three new facts about price setting by multi-product firms. First, firms selling more goods adjust prices more frequently but on average by smaller amounts. Moreover, their fraction of positive price changes is lower and the dispersion of price changes is higher. Second, price changes within firms are substantially synchronized, which plays a dominant role in explaining pricing dynamics. Third, firms selling more goods have greater within-firm synchronization of price changes. A model with trend inflation and firm-specific menu costs where firms are subject to idiosyncratic and aggregate shocks matches the empirical findings.     

Pass-Through of Exchange Rates and Competition between Floaters and Fixers

This paper studies how a rise in the share of U.S. imports from China, or any country with a fixed exchange rate, can explain a disproportionate fall in exchange rate pass-through to U.S. import prices. A theoretical model provides an explanation working through changes in markups, showing that a particular "local bias" condition is necessary and that free entry amplifies the effect. The model produces a structural equation for pass-through regressions including the China share; panel regressions over 1993–2006 indicate that the rising share of trade from China or other exchange rate fixers can explain as much as one-half of the observed decline in pass-through for the United States.     

The Impact of Renminbi Appreciation on Stock Prices in China

Since removal of the peg in July 2005, China has entered a new era of a managed floating exchange rate system. Although many observers have raised concerns about the impact of such a policy change on China's trade surplus, less attention has been paid to its effects on financial markets. This paper investigates the impact of recent renminbi appreciation on stock prices in China since removal of the peg, using threshold cointegration and momentum threshold error-correction model (M-TECM). The results clearly illustrate that no short-run causal relation exists, and an asymmetric causal relationship running from the renminbi/U. S. dollar exchange rate to Chinese Shanghai A-share stock prices in the long run is based on M-TECM. Policy and the broader implications of the findings are discussed.     

Sectoral Comovement,Monetary Policy Shocks,and Input–Output Structure

The comovement of output across the sector producing nondurables (i.e., nondurable goods and services) and the sector producing durables is well established in the monetary business cycle literature. However, standard sticky‐price models that incorporate sectoral heterogeneity in price stickiness (i.e., sticky nondurables prices and flexible durables prices) cannot generate this feature. We argue that an input–output (I–O) structure provides a solution to this problem. Here, we develop a two‐sector model with an I–O structure, which is calibrated to the U.S. economy. In the model, each sector’s output affects those of the others by acting as an intermediate input. This connection between the sectors provides a channel through which sectoral comovement is induced.     

Liquidity and the dynamic pattern of asset price adjustment: A global view

Global liquidity expansion has been very dynamic since 2001. Contrary to conventional wisdom, high money growth rates have not coincided with a concurrent rise in goods prices. At the same time, however, asset prices have increased sharply, significantly outpacing the subdued development in consumer prices. We investigate the interactions between money and goods and asset prices at the global level. Using aggregated data for major OECD countries, our VAR results support the view that different price elasticities on asset and goods markets explain the observed relative price change between asset classes and consumer goods.     

Relative Prices as Aggregate Supply Shocks with Trend Inflation

Ball and Mankiw (1995) use a static menu-cost model to explain the historical behavior of the first and higher moments of commodity price changes in U.S. producer prices. We show that when appropriately modified for a world of positive trend inflation and forward-looking behavior by firms, the menu-cost model predicts a much weaker (possibly zero) correlation between the mean and the skewness of price changes than that found in the data.     

International dimensions of optimal monetary policy

This paper provides a baseline general equilibrium model of optimal monetary policy among interdependent economies with monopolistic firms and nominal rigidities. An inward-looking policy of domestic price stabilization is not optimal when firms’ markups are exposed to currency fluctuations. Such a policy raises exchange rate volatility, leading foreign exporters to charge higher prices vis-à-vis increased uncertainty in the export market. As higher import prices reduce the purchasing power of domestic consumers, optimal monetary rules trade off a larger domestic output gap against lower consumer prices. Optimal rules in a world Nash equilibrium lead to less exchange rate volatility relative to both inward-looking rules and discretionary policies, even when the latter do not suffer from any inflationary (or deflationary) bias. Gains from international monetary cooperation are related in a non-monotonic way to the degree of exchange rate pass-through.     

The optimal currency basket under vertical trade

This paper explores the theory of optimal currency basket in a small open economy general equilibrium model with sticky prices. In contrast to existing literature, we focus on an economy with vertical trade, where the currencies in the basket may play different roles in invoicing trade flow. In a simple two-currency basket, one currency is used to invoice imported intermediate goods and is called “import currency”, while the other currency is used to invoice exported finished goods and is called “export currency”. We find that the optimal weights of the import currency and the export currency depends critically on the structure of vertical trade. Moreover, if a country decides to choose a single-currency peg, the choice of pegging currency also depends on how other competing economies respond to external exchange rate fluctuations.     

Understanding Post‐Euro Law‐of‐One‐Price Deviations

We put together a unique panel of thousands of good‐level prices before and after the euro to compare the determinants and understand the evolution of goods price dispersion across Europe over time. We find that tradeability and nontraded inputs play a significantly smaller role for cross‐country price dispersion after the adoption of the euro, and for Eurozone economies as compared to European Union ones. We then compare the distributions of law‐of‐one‐price (LOP) deviations over time to understand how the degree of integration across European economies changed after the euro. Our tests reveal that the distributions after the euro are typically significantly different from those before, consistent with a greater degree of integration. Utilizing our unique panel data set to trace the location of individual goods in the distribution of LOP deviations, we ask how the price advantage or disadvantage evident in these price distributions evolves over time, and whether goods characteristics play a role for the persistence of these LOP deviations. LOP deviations for these goods are highly correlated over 5‐ or 10‐ year horizons, and correlations remain significantly high over longer horizons. These correlations are greater for homogeneous as compared to differentiated goods and vary across countries. Finally, for most of these European economies and goods, price advantage is typically revealed to be more persistent than price disadvantage.     

Income shifting and U.S. international trade in goods statistics

Intrafirm trade represents greater than one-third of total U.S. international trade in goods. Since these are not arm’s-length transactions, trade policymakers have voiced concerns that income shifting may distort international trade in goods statistics through the manipulation of transfer prices. Using country-level data on intrafirm exports and imports, we estimate a path analysis that simultaneously tests how and to what extent tax-motivated transfer pricing and real investment decisions affect intrafirm trade in goods statistics. Contrary to speculation, we do not find an economically significant relation between transfer pricing and intrafirm trade in goods statistics. In contrast, we find that tax-motivated location decisions create a 21 (20) percent or $819.7 ($927.1) million difference in mean intrafirm exports (imports) between the U.S. and a low- and high-tax country. This study provides trade policymakers with relevant information about the extent to which real investment decisions and accounting manipulations affect intrafirm trade in goods statistics and contributes to the international trade and income shifting literatures.     

Exchange Rate Changes and Inflation in Post‐Crisis Asian Economies: Vector Autoregression Analysis of the Exchange Rate Pass‐Through

Macro‐economic consequences of large currency depreciations among the crisis‐hit Asian economies varied from one country to another. Inflation did not soar after the Asian currency crisis of 1997–98 in most crisis‐hit countries except Indonesia where high inflation followed a very large nominal depreciation of the rupiah. The high inflation meant a loss of price competitive advantage, a key for economic recovery from a crisis. This paper examines the pass‐through effects of exchange rate changes on the domestic prices in the East Asian economies using a vector autoregression analysis. The main results are as follows: (i) the degree of exchange rate pass‐through to import prices was quite high in the crisis‐hit economies; (ii) the pass‐through to Consumer Price Index (CPI) was generally low, with a notable exception of Indonesia; and (iii) in Indonesia, both the impulse response of monetary policy variables to exchange rate shocks and that of CPI to monetary policy shocks were positive, large, and statistically significant. Thus, Indonesia's accommodative monetary policy, coupled with the high degree of CPI responsiveness to exchange rate changes was an important factor in the inflation‐depreciation spiral in the wake of the currency crisis.
