The Dollar Exposure of Japanese Companies

The bulk of Japanese exports and imports are denominated in U.S. dollars rather than Japan's local currency, the yen. The consequences of dollar invoicing depend importantly on the extent to which Japanese companies hedge their dollar exposures. If they fully hedge their dollar exposures, then the choice of invoicing currency will not influence the yen profits of Japanese companies. This paper examines the degree to which Japanese companies hedge by estimating their exposure to movements in the dollar. Using Japanese stock market data and an international version of the CAPM model I estimate the extent to which Japanese company returns are correlated with changes in the yen–dollar exchange rate. The results suggest many Japanese companies are indeed exposed to yen–dollar movements and that dollar appreciations generally are positively correlated with firm returns. Since over the period 1984 to 1995, the dollar depreciated by 36% relative to the yen, it follows that the values of Japanese companies fell as a consequence of their dollar exposure.J. Japan. Int.

The Role of Nominal Anchor Currencies in Exchange Rate Arrangements

This paper studies the evolution of exchange rate arrangements of almost all countries in the world over the period 1970–1996. It examines both officially reported and empirically observed exchange rate arrangements. Several findings are obtained. First, the relative economic size of countries under fixed exchange rate regimes has not declined as dramatically as the measure based on reported arrangements would indicate. Second, the U.S. dollar has been the most dominant, global anchor currency because many developing economies, particularly those in Asia, Latin America, and the Middle East, have attempted to stabilize their exchange rates to the dollar. Third, the reserve currency composition is determined by the constructed measure of the net currency-area size in addition to the own-economic size of the reserve currency country. Fourth, as a result of the transition to the final stage of EMU, the euro is expected to emerge as the world's second most dominant anchor currency. While the Japanese yen will continue to play a less significant role as nominal anchor, its role in East Asia is expected to rise gradually.J. Japan. Int. Econ.December 1998,12(4), pp. 334–387.

The Exchange Rate Policy of the Euro: A Matter of Size?

This paper analyzes how country size affects exchange rate policy and volatility. A hump shaped relation between exchange rate variability and the size of countries is generated in the theoretical model: exchange rate variability increases with country size for small countries but then decreases for large countries. The paper finds that this theoretical prediction holds well for bilateral exchange rates of the OECD countries in the period between 1980 and 1995 as well as for a subsample of European exchange rates with respect to the dollar. The results suggest that the dollar/euro volability may be lower than the present dollar/DM volatility.J. Japan. Int. Econ., Dec. 1998,12(4), pp. 455–482.

The Euro as a Reserve Currency

This paper presents historical and econometric evidence that the euro will come to rival the dollar as a reserve currency only slowly. The fact that it pays for central banks to hold their foreign reserves in a currency that is widely used in international transactions creates a network externality that gives the dollar an incumbency advantage. In addition, creating a market with sufficient stability to be attractive to international investors requires continuous liquidity management and periodic lender-of-last-resort operations by the issuing central bank. That the Maastricht Treaty assumes a strong separation between monetary policy and prudential regulation consequently bodes ill for the euro's prospects as a reserve currency.J. Japan. Int.

China's Exchange Rate Movements and Corporate Currency Invoicing Strategies

Since China introduced a new managed floating exchange rate regime in 2005, the persistent appreciation of the renminbi against the US dollar has led Chinese firms to reassess their choice of invoice currency among the dollar and other international alternatives to price their exports. The present paper performs a systematic invoice currency analysis by surveying the published literature, summarizing criteria for decision-making, and evaluating the choices available to Chinese exporters implementing currency invoicing strategies to maximize expected profits. This study finds that the euro could play an increasing role as the invoice currency of Chinese firms, although the US dollar will still play a dominant role. Chinese exporters might shift gradually from the dollar to the euro in the face of the falling dollar, balancing between the two by necessity.     

Optimal currency shares in international reserves: The impact of the euro and the prospects for the dollar

Foreign exchange reserve accumulation has risen dramatically in recent years. The introduction of the euro, greater liquidity in other major currencies, and the rising current account deficits and external debt of the United States have increased the pressure on central banks to diversify away from the US dollar. A major portfolio shift would significantly affect exchange rates and the status of the dollar as the dominant international currency. We develop a dynamic mean-variance optimization framework with portfolio rebalancing costs to estimate optimal portfolio weights among the main international currencies. Making various assumptions on expected currency returns and the variance–covariance structure, we assess how the euro has changed this allocation. We then perform simulations for the optimal currency allocations of four large emerging market countries (Brazil, Russia, India and China), adding constraints that reflect a central bank's desire to hold a sizable portion of its portfolio in the currencies of its peg, its foreign debt and its international trade. Our main results are: (i) The optimizer can match the large share of the US dollar in reserves, when the dollar is the reference (risk-free) currency. (ii) The optimum portfolios show a much lower weight for the euro than is observed. This suggests that the euro may already enjoy an enhanced role as an international reserve currency (“punching above its weight”). (iii) Growth in issuance of euro-denominated securities, a rise in euro zone trade with key emerging markets, and increased use of the euro as a currency peg, would all work towards raising the optimal euro shares, with the last factor being quantitatively the most important.

Invoicing currency and the optimal basket peg for East Asia: Analysis using a new open economy macroeconomic model

An important characteristic of trade in Asia is that the US dollar is the dominant invoicing currency. This fact might have a consequence on the region's choice of the currency regime. To investigate this possibility, I develop a three country “new open economy macroeconomics” model that consists of East Asia, Japan, and the US. Assuming that East Asia pegs its currency to a basket of the other two's currencies, the optimal basket weights are derived numerically. It is shown that the weights under a realistic invoicing pattern are drastically different from those in the textbook case of “producer currency pricing.” J. Japanese Int. Economies 20 (4) (2006) 569–589.     

What the euro means for the dollar and the international Monetary system

This article begins by analyzing the hirtorical importance of the introduction of the euro, the convergence criteria for membership in the European Monetary Union, the merits and defects of the euro as an international rival to the dollar, and the characteristics that have made past international currencies great. It goes on to consider the institutional gap in the world system arising from the absence of an official world currency and the threat to stability that arises in transition periods when a new international reserve asset or currency is phased in. It is argued that the introduction of the euro will involve diversification from the dollar that will require multilateral attention to the dollar-euro exchange rate.Distinguished Address presented at the Forty-Fifth International Atlantic Economic Conference, Rome, Italy, March 14–21, 1998.     

Purchasing Power Parity before and after the Adoption of the Euro

This paper examines the purchasing power parity (PPP) hypothesis for the post–Bretton Woods era including the period after the introduction of the euro. The study applies a new nonlinear unit root test to the bilateral real exchange rates (RERs) of both European and other industrial countries with the French franc and German mark (and the euro after 1998), as well as the US dollar as numeraire currencies. The results of the study provide stronger support for PPP than any earlier studies of bilateral PPP for industrial countries and suggest that (1) PPP tends to hold well within the European Union (EU) even before the adoption of the euro, (2) the evidence for PPP becomes more significant for both EU and non-EU countries when the sample period is extended to the euro era, and (3) convergence toward PPP between the EU countries, especially between the euro-area countries, tends to be nonlinear, while it is likely to be linear for the non-EU industrial countries.

The Euro and the Dollar, 1998

There is no immediate prospect for the euro to become an anchor currency outside Central Europe and the Mediterranean. Still, a successful euro could deepen European financial markets and attract more international investment to the euro area. The prospect of substantial portfolio shifts into the euro, however, does not justify forecasts that the new currency will appreciate against the dollar over an extended time horizon. Liability managers outside the euro area should also find the enhanced liquidity and improved diversification possibilities of euro-denominated debt attractive.     

The Euro and International Equity Flows

We use a new panel data set on bilateral gross cross-border equity flows between 14 countries. We fit a “gravity model” to these data and a strictly comparable set of data for manufactures trade between these countries. The results are strikingly similar, although the coefficient on the distance variable is lower for equity than for trade flows (but still highly significant). We use the results to throw some light on the likely consequences of unifying the European equity markets.J. Japan. Int. Econ.December 1998,12(4), pp. 406–423.

Should East Asia’s currencies be pegged to the yen? The role of invoice currency

Growing concern that a dollar peg exposes East Asian economies to fluctuations in the dollar–yen exchange rate has stimulated research on currency basket regimes as alternatives for these economies. However, existing studies have mostly ignored an important characteristic of East Asia, i.e., most of its international trade is invoiced in the U.S. dollars. This paper investigates how the preponderance of dollar invoicing affects optimal currency basket regimes for East Asian economies. I develop a three-country center-periphery sticky-price dynamic stochastic general equilibrium model for the analysis. The model is solved numerically by taking second-order approximations to the policy functions with the expected lifetime utility of households chosen as the welfare criterion. Contrary to the conjecture of existing literature, I show that predominance of dollar invoicing implies that the dollar should receive a smaller weight than suggested by bilateral trade shares between emerging markets in East Asia and the United States. The results hinge on the interaction of different degrees of pass-through implied by the choice of invoice currency and endogenous responses of monetary policies in the center countries.     

Fixed Exchange Rates and Disinflation in Emerging Markets: How Large Is the Effect?

We examine developing countries which have institutional quality ratings for the effects of exchange rate rigidity on inflation. The level of institutional development exerts no effect on the impact of currency regimes. However, the interaction of institutional quality and exchange rates has, in the most plausible specifications, a negative impact on inflation. This suggests that fixed exchange rates exert at most a contingent effect on inflation, and indicates that countries in Eastern Europe and Latin America contemplating currency pegs would be better off improving institutional quality prior to adopting the euro or dollar and expecting a large subsequent disinflationary effect.

The choice of an invoicing currency in international trade and the balance of trade impact of currency depreciation

Cross-country differences in the choice of an invoicing currency in international trade is one reason for cross-country differences in estimated exchange rate coefficients in short-run balance of trade equations. If exports are invoiced in domestic currency while imports are invoiced in a foreign currency, a depreciation will increase the domestic currency value of outstanding import contracts, and may cause the balance of trade to fall in the short run. Countries with different invoicing patterns will have different effects on the short-run trade balance following a depreciation. We explore a simple theory of invoicing currency choice, drawing inferences regarding the likely choices for 14 countries. This allows a classification of countries according to the expected short-run balance of trade effect of a currency depreciation. Empirical estimates support the hypothesized groupings based on suggested currency invoicing patterns.     

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。     

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.

Currency unions and trade: The special case of EMU

In this paper, the impact of the adoption of the euro on the commercial transactions of EMU countries is investigated. It seeks to disentangle the effects of eliminating exchange rate volatility — and those of other policy factors that promote integration — from the influence of the emergence of the European currency union. Since EMU is a relatively new phenomenon, a panel estimation of the gravity equation in a dynamic framework is used in order to capture effects like trade persistence. The main finding is that the adoption of the euro has had a positive but not an exorbitant impact on bilateral trade between European countries (ranging between 9 and 10 per cent). The impact is much lower than that shown in the recent literature on a larger and heterogeneous set of countries. One reason for this divergence seems to be that the euro was adopted after decades of integration policies had already worked through in Europe. JEL no. F4, F15, C230     

欧洲央行长期再融资操作政策研究

本文对欧洲央行实施的两轮3年期长期再融资操作政策进行了研究。与一般的量化宽松政策相比,二者虽然都是通过扩张央行的资产负债表缓解了市场流动性紧张,但在实施的前提条件、资产负债表的扩张方式、期限与规模的确定、实施主体的地位等诸多方面存在差异。研究发现该政策在一定程度上缓解了欧债危机的持续恶化,降低了融资成本,提振了市场信心;但对实体经济的刺激作用还有待观察,也未能帮助欧元区银行获取无风险套利。此外,市场对欧洲央行承诺效应的怀疑将在很大程度上影响该政策的操作效果,欧元区货币超发将引发"以邻为壑"效应,同时将干扰欧元区的物价稳定。基于上述风险,本文提出了相应的政策建议。     

The Euro as a Monetary Anchor in the CEECs

We study whether Central and Eastern European Countries (CEECs) have an incentive to use the euro as a monetary anchor. Adapting a cross-section estimation method initiated by Bayoumi and Eichengreen, we show that, compared to an optimum currency area standard, the CEECs have paid too much attention to the USD in the past and should prefer the euro to the dollar as a nominal anchor. Through a theoretical model that takes external constraints into account, we then show that the CEECs should also have an incentive to stabilize their currencies in real terms against a basket where the euro would be prominent.     

The Spillover Effect of Euro Area on Central and Southeastern European Economies: A Global VAR Approach

We use the global vector autoregression model to examine macroeconomic spillovers within the European Union over the period 2000-2014. We investigate how shocks originating in the euro area affect output and prices in the rest of Europe. We examine four different policy relevant shock scenarios: (i) increase in the euro area interest rate; (ii) increase in the euro area industrial production; (iii) decrease in the euro area consumer prices and (iv) decrease in global oil prices. In general, we find that these shocks have an effect of same (and expected) sign but of different size across the European Union. Our results suggest that the response of Central European countries to the euro area shocks is almost as strong as the response of the euro area countries itself. On the other hand, our results indicate that South East Europe is somewhat less sensitive to the euro area shocks and oil price shocks.
