The Sources of Fluctuations Within and Across Countries

This paper reviews the evidence on the sources of business cycles within and across countries and the implications for the importance of borders in business cycles. A simple econometric model is presented and applied to within-U.S. and cross-country data in order to provide a framework for interpreting the literature. Using these estimates as a benchmark, data issues, alternative models, and still other approaches to quantifying sources of comovement are surveyed. Overall, the evidence suggests three general conclusions. First, common shocks are less important in international fluctuations than in within-country fluctuations. Second, region-specific shocks account for a larger share of variation in international data than in within-country data. Finally, industry-specific shocks, measured accurately, are a smaller source of variation internationally than within countries. The paper then argues that lowering economic borders among nations through pacts like EMU should make the sources of international fluctuations look somewhat more like the sources of within-country fluctuations, although the effects are uncertain.

Trade integration and business cycle co-movements: the case of Korea with other Asian countries

Abstract As Korea increases its trade within Asia, it is becoming more and more integrated with the other economies in the region. Theoretically, increased trade can lead business cycles across trading partners to be patterned in either direction, towards convergence or divergence. By using data for 12 Asian economies, this paper finds that intra-industry trade is the major channel by which the business cycle of Korea becomes synchronized with that of other Asian economies, although increased trade itself does not necessarily lead to close business cycle coherence.

A Currency Union in East Asia

This paper investigates prospects of a currency union in East Asia, focusing on trade and financial integration occurring in the region. We find, based on a dynamic factor model, regional common shocks have been quantitatively important for output variations in the Asian economies. We expect that continuing trade integration in the region will lead to further synchronization of business cycles, thereby encouraging East Asian countries to create a currency union in the region. In contrast to trade, however, financial liberalization in East Asia tends to lead to more global integration, rather than regional integration, of the financial systems, and thereby is not likely to develop favorable conditions for forming a regional currency union among East Asian countries.

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.

Economic Integration and Changes in the Business Cycle in East Asia: Is the Region Decoupling from the Rest of the World?*

Countries in East Asia (EA) have made a great deal of progress in integrating their economies since the early 1990s. There has been a sustained increase in intra-regional trade in EA. On finance, however, regional financial integration has been lagging behind trade integration and EA has reached out to global financial markets to effect deeper global integration. The purpose of this paper is to analyze the effects of intra-regional and extra-regional financial integration on changes in the pattern of EAs business cycle since 1990 to see whether there is any ground for decoupling of EA from the United States and the EU. On trade relations, the empirical results show that deepening trade integration contributes to more synchronized output movements among EA countries. There is also evidence that financial integration enhances more synchronization of output, but because its impact is not strong, the extra-regional integration does not necessarily dispute the prediction that EAs output movement has become more idiosyncratic than before, and therefore less closely tied with that of the United States.

Risk Sharing by Households within and Across Regions and Industries

Cochrane (1991) and Mace (1991) test if risk sharing across households is complete in the sense that household consumption moves one-for-one with aggregate consumption. In their studies the source of income risk is idiosyncratic, and agents can share risk across the entire economy. Using a sample of households from the Panel Study on Income Dynamics (PSID), we explore whether individuals diversify the risk associated within their industries and regions, as well as across industries and regions. We find that there is stronger evidence of within region and industry risk sharing than across region and industry risk sharing. In neither case, however, is the risk sharing complete.

Saving, Investment, and Current Account Surplus in Developing Asia

An integral part of global current account imbalances is the large and persistent current account surplus developing Asia has run since the 1997–1998 Asian crisis. A country’s current account surplus is, by definition, equal to its net saving. The central objective of this paper is to investigate the extent to which the saving and investment rate of Asian countries can be explained by the underlying fundamental determinants of saving and investment such as gross domestic product growth and demographic factors. Our empirical analysis yields two key findings. First, we find stronger evidence of oversaving than underinvestment in the region. Second, we find stronger evidence of overinvestment prior to the Asian crisis than underinvestment after the Asian crisis. This suggests that the key to rebalancing Asian growth toward domestic sources lies in promoting consumption rather than investment.

Can Trade with the People’s Republic of China be an Engine of Growth for Developing Asia?

The recession in the United States in the wake of the global financial crisis has had a pronounced negative impact on developing Asia’s exports and growth. As a result, developing Asian countries are increasingly looking to the People’s Republic of China (PRC) as a new source of demand and growth. The central objective of this paper is to empirically assess whether trade with the PRC can become an engine of growth for developing Asia. To do so, we examine the structure of PRC’s trade with developing Asia, in particular the relative shares of parts and components versus final goods in its imports from the region. Our most significant result is that the share of final goods in the PRC’s imports from East and Southeast Asia has been rising while the share of parts and components has been falling, suggesting that the PRC is becoming more of a consumer and less of an assembler. This provides ground for optimism about the prospects of trade with the PRC as a source of resilience against extra-regional demand shocks in the short run and an additional source of growth in the long run.

The Service Sector in Asia: Is It an Engine of Growth?

The underdeveloped service sector in Asia has the potential to become a new engine of economic growth for developing Asia, which has traditionally relied on export-oriented manufacturing to power its growth. The central objective of this paper is to empirically analyze the prospects for the service sector as a future engine of growth. Our analysis of 12 Asian economies indicates that the service sector already contributed substantially to the region’s growth in the past. Furthermore, somewhat surprisingly in light of the difficulty of achieving productivity gains in services, we also find that services labor productivity grew at a healthy pace in much of the region. Overall our analysis provides substantial cause for optimism about the role of the service sector as an engine of growth in Asia. However, some Asian countries where the service sector is currently struggling, such as the Republic of Korea and Thailand, will find it more challenging to develop the sector.

IMF bailouts and moral hazard

This paper empirically investigates the extent of investor moral hazard associated with IMF bailouts by analyzing the responses of sovereign bond spreads to the changes in the perceived probability of IMF bailouts of countries undergoing financial crisis. We do not find strong evidence that the extent of investor moral hazard changed after the non-bailout of Russia in August 1998 that signaled a modification to IMF intervention policy. In contrast, we find evidence that investor moral hazard is intensified for those countries that have stronger political connections to the IMF and that are thereby more likely to be bailed out by the IMF. This pattern prevailed even after the Russian crisis.
