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.     

Economic Integration in East Asia: An International Input‐Output Analysis

To establish economic and monetary union (EMU) in East Asia, deepening regional integration through international trade is important. The economic interdependence (one of the important criteria for regional integration) study, using macro data does not reflect the indirect effects generated by interactions between different production sectors and different countries. We use the international input‐output (IIO) framework to study the economic interdependence at both macro and production sector levels. We refine the existing methods to reflect exogenous country effect and size effect of the economy. Our study suggests that establishing EMU in East Asia appears to be somewhat premature. However, we can be more optimistic for regional integration at the production sector level in East Asia when including Japan, which will create a basis for EMU in the region.     

Trade and Financial Integration in East Asia: Effects on Co‐movements

In this paper we explore three important areas where deeper trade and financial integration in East Asia can influence: (1) business cycle co‐movements in the region, (2) the extent of risk sharing across countries and (3) price co‐movements across countries. We find evidence that trade integration enhances co‐movements of output but not of consumption across countries. Especially the fact that trade integration does not raise co‐movements of consumption as much as that of output is interpreted as trade integration does not improve the extent of risk sharing. Co‐movements of price arise most significantly as trade integration deepens, lowering the border effects and allowing better opportunities for resource reallocation across countries. In contrast, financial integration demonstrates much weaker evidence of enhancing co‐movements across countries. Deeper financial integration improves price co‐movements weakly but does not enhance output or consumption co‐movements at all. However, since the current level of financial integration in East Asia is quite low, our evidence is too early to firmly determine the role of financial integration.     

Real Output Co‐movements in East Asia: Any Evidence for a Monetary Union?

The East Asian region has experienced astonishing economic growth and integration over the past few decades. It is generally believed that a high degree of integration in the region would greatly shape the economic structure of each individual economy and has direct implications for the effectiveness of domestic stabilisation policy and policy coordination. This paper empirically examines the feasibility of forming a monetary union in East Asia by assessing the real output co‐movements among these economies. As suggested by the optimum currency area (OCA) theory that losing monetary independence would be the major cost for adopting a common currency, it would be less costly for the economies to form a monetary union if the business cycles are synchronised across countries. The cointegration test and the Vahid and Engle (1993 ) test for common business cycles are conducted to examine their long‐run relationship and short‐run interactions in real outputs, respectively. Our study found that some pair countries in the region share both the long‐run and short‐run synchronous movements of the real outputs. In particular, the short‐run common business cycles are found in some pairs of ASEAN economies consisting of Singapore, Thailand and Indonesia, and in the Northeast Asian region consisting of Hong Kong, Korea and Mainland China, as well as between Japan and Taiwan. These findings have important implications for the economies in terms of adjustment costs when considering the adoption of a monetary union.

AMU Deviation Indicators for Coordinated Exchange Rate Policies in East Asia and their Relationships with Effective Exchange Rates

After the Asian currency crisis in 1997, the monetary authorities of East Asian countries have been strengthening their regional monetary cooperation. In this paper, we propose a deviation measurement for coordinated exchange rate policies in East Asia to enhance the monetary authorities’ surveillance process for their regional monetary cooperation. We calculate an Asian Monetary Unit (AMU) as a weighted average of East Asian currencies following the method used to calculate the European Currency Unit (ECU). Also, we calculate AMU Deviation Indicators which show how much each of the East Asian currencies deviates from a hypothetical benchmark rate in terms of the AMU. Furthermore, we investigate relationships between the AMU Deviation Indicators and the effective exchange rates, which mean international price competitiveness in terms of international trade. We found strong relationships between the AMU Deviation Indicators and the effective exchange rates except for some currencies. The results suggest that monitoring the AMU Deviation Indicator will be useful for the monetary authorities’ surveillance in East Asia in order to stabilise their effective exchange rate or price competitiveness among the East Asian countries.     

Currency Prices, the Nominal Exchange Rate, and Security Prices in a Two‐Country Dynamic Monetary Equilibrium

This paper examines a continuous‐time two‐country dynamic monetary equilibrium in which countries with possibly heterogeneous tastes and endowments hold their own money for the purpose of transaction services formulated via money in the utility function. Given a price system, no‐arbitrage pricing results are provided for the price of each money and the nominal exchange rate. Characterizations are provided for equilibrium prices for general time‐additive preferences and non‐Markovian exogenous processes. Under a Markovian structure of model primitives, the currency prices are shown to solve a bivariate system of partial differential equations. Assuming that each country is endowed with heterogeneous separable power utility and the exogenous quantities all follow geometric Brownian motions, an equilibrium is shown to exist and additional characterization is provided. A further example of nonseparable Cobb–Douglas preferences is investigated. The additional features over the customary environment of homogeneous logarithmic preferences are emphasized.     

Exchange Rate Volatility and Intra‐Asia Trade: Evidence by Type of Goods

This paper examines the impact of intra‐Asia exchange rate volatility on intra‐Asia trade in primary goods, intermediate goods, equipment goods and consumption goods from 1980 to 2009. For Asia, the evidence shows that as intraregional exchange rate volatility increases, intraregional exports in these goods fall. This adverse impact is even more pronounced in the subregion of Association of Southeast Asian Nations (ASEAN)+5 comprising ASEAN member countries plus the People's Republic of China; Hong Kong, China; Japan; the Republic of Korea; and Taipei, China; and especially among intermediate and equipment exports. Again, the impact magnifies in an even smaller subgroup excluding the smaller ASEAN economies. These results underline the significant impact of exchange rate volatility on the region's production networks. For South Asia, however, exchange rate volatility appears to have a positive impact on exports. Still, caution is warranted given that South Asian economies trade relatively little with each other.     

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.     

A Political Economic Critique on the Theory of Optimum Currency Areas,and the Implications for East Asia

In recent years, dynamic debate has arisen as to the desirability and feasibility of creating a monetary union in East Asia. While the debate has relied heavily on the theory of optimum currency areas, this theory has weaknesses in explaining the actual formation of monetary unions. At this point, political economy analysis appears to demonstrate stronger explanatory power. This paper provides a systematic review of the main developments in the literature on optimum currency area theory and in the political economy literature on monetary union. In addition, it addresses the feasibility of an East Asian monetary union, by applying the findings in these two academic strands to the region. It finds that even though formation of an East Asian monetary union may be to some extent feasible from an economic perspective, the region’s political situation does not appear favourable for the creation of one.     

An Asian Currency Unit: Simulations for Its Effects on East Asia

An Asian currency unit (ACU) is necessary to deepen Asian financial markets and to convert national currencies into a single monetary policy. However, the experiences of the European Currency Unit and the European Exchange Rate Mechanism crisis in 1992–93 have indicated the danger of the so‐called gradual approach. This study evaluates the effects of welfare should the ACU indicator become a long‐term constraint of the People's Republic of China and Japan, the big two in East Asia. Our results indicate that the constraints of countries’ own baskets (e.g. real effective exchange rates) are still better before the launch of a true single currency. That is, pegging to an ACU indicator could hardly be sustained in the long‐run if East Asian countries have not reached a consensus about a regional monetary union.     

Synchronised Business Cycles in East Asia and Fluctuations in the Yen/Dollar Exchange Rate

Because many authors have proposed stimulating the ailing Japanese economy by monetary expansion and yen depreciation, we explore the repercussions of depreciating the yen against the dollar on the other East Asian economies – which largely peg to the dollar. Since 1980, economic integration among Japan's neighbours – China, Hong Kong, Indonesia, Korea, Malaysia, Philippines, Singapore and Thailand – has intensified and (except for China and Singapore) their business cycles have been highly synchronised. These cycles have been closely linked to fluctuations in the yen/dollar exchange rate – through changes in the export competitiveness, inflows of foreign direct investment and intra‐Asian income effects. We show that a major yen devaluation would have a negative impact on incomes in other East Asian economies and that it is not a sensible policy option for Japan.     

Financial Integration in East Asia: An Empirical Investigation

The central objective of this paper is to empirically evaluate the degree of linkages among East Asian equity and bond markets. Using data from the IMF’s Coordinated Portfolio Investment Survey (CPIS), we find that intra‐East Asian financial asset holdings of four East Asian countries – Japan, Korea, Hong Kong and Singapore – are larger than the levels predicted by the financial gravity model. However, our analysis suggests that this result is likely to be driven by intra‐regional trade linkages and reflect those linkages. Therefore, the salient implication for regional policymakers is that they should continue to promote intra‐regional financial integration. This paper also aims to analyse the impact of three different types of country‐specific risks – political, economic and financial risks – on investment from the four countries. This analysis yields a clear positive relationship between destination‐country risk, in particular political risk, and capital inflows.     

Designing EU–US Atlantic Monetary Relations: Exchange Rate Variability and Labour Markets

The variability of the euro seems to have a statistically significant and economically small, but non‐negligible, impact on labour markets in Euroland. Unemployment tends to increase and employment growth tends to fall whenever the effective exchange rate of the euro or the bilateral euro/dollar exchange rate becomes more variable. In the US a similar effect seems to be operating, but it is statistically less strong, especially concerning employment growth, which seems largely insulated from exchange rate variability. These results fit the general observation that US labour markets are more flexible and that the euro area is considerably more open than the US (exports of goods and services amount to close to 18 per cent of Euroland GDP versus only about 11 per cent for the US).     

Labour Migration and Economic Growth in East and South‐East Asia

East and South‐East Asia will face major demographic changes over the next few decades with many countries’ labour forces starting to decline, while others experience higher labour force growth as populations and/or participation rates increase. A well‐managed labour migration strategy presents itself as a mechanism for ameliorating the impending labour shortages in some East Asia–Pacific countries, while providing an opportunity for other countries with excess labour to provide migrant workers who will contribute to the development of the home country through greater remittance flows. This paper examines such migration policy options using a global dynamic economic simulation approach and finds that allowing migrants to respond to the major demographic changes occurring in Asia over the next 50 years would be beneficial to most economies in the region in terms of real incomes and real GDP over the 2007–50 period. Such a policy could deeply affect the net migration position of a country. Countries that were net recipients under current migration policies might become net senders under the more liberal policy regime.
