This paper analyzes the evolution of volatility and cross-country comovement in output, consumption, and investment fluctuations using two distinct datasets. The results suggest that there has been a significant decline in the volatility of business cycle fluctuations and a slight increase in the degree of cyclical comovement among industrialized countries over time. However, for emerging market economies, financial globalization appears to have been associated, on average, with an increase in macroeconomic volatility as well as declines in the degree of comovement of output and consumption growth with their corresponding world aggregates.

This paper develops a direct, explicit model for the contribution of exchange rate fluctuations and examine how and to what extent international stock market volatility and cross-market correlations are influenced by exchange rate fluctuations. Evidence presented in this paper indicates that a higher foreign exchange rate variability contributes mostly to a higher local stock market volatility but to a lower volatility for the US stock market. The extent to which the stock market volatility is influenced by a foreign exchange variability is greater for local markets than for the US market, due to the fact that exchange rate changes are more strongly correlated with the local equity market returns than the US market returns. We also find that a higher exchange rate fluctuation contributes marginally to a lower US/local equity market correlation in most cases. While exchange rate fluctuations held a relatively large fraction of the variation in local stock market returns, there was no significant influence on the US/local market correlation.

This paper investigates the relationship between international capital liberalization and exchange rate volatility. While the effects of a capital controls liberalization on the transaction volume in the foreign exchange market are theoretically unambiguous, the effects on the volatility of exchange rate can have either sign. On one hand, the liberalization leads to increasing economy-wide and investor-specific uncertainty. On the other hand, the augiented number of participants in the market should reduce exchange rate fluctuations. The uncertainty effects should be dominant in the short run, while the increase in the number of traders in the longer run should make the market thicker and tend to reduce volatility. It is shown that, for a sample of countries which have liberalized capital controls in the last 15 years, structural breaks in the process generating exchange rate volatility have occurred very close to the time when liberalization measures were implemented. The results also suggest an increase in volatility after the structural breakpoint.

It is now abundantly clear that stock volatility is a contagious disease that spreads virulently from market to market around the world. Price changes in one market drive subsequent price changes in that market as well as in others. In Beast, Haugen makes a compelling case for the fact that even under normal conditions, fully 80 percent of stock volatility is price driven. Moreover, this volatility is far from benign. It acts to reduce the level of investment spending and constitutes a significant and permanent drag on economic growth. Price-driven volatility is unstable. Dramatic and unpredictable explosions in price-driven volatility can send stock markets in a downward spiral and cause significant disruptions in economic activity. Haugen argues that this indeed happened in 1929 and 1930. If volatility in Asian markets persists, it can easily become the source of the problem rather than merely a symptom.

The interrelationship between international stock markets is becoming a key issue in international portfolio managment and risk measurement. The dynamics of security returns and their risk characteristics have a crucial role in the financial market's therory. Recent empirical studies have tested market efficiency measuring the degree of integration of international financial markets. These studies have shown that international markets react quickly to news but they are volatile and difficult to predict and with a changing correlation structure of security returns among countries.In this paper we analyze the nature of the relationship between the major international stock markets in Canada, Japan, U.K. and the U.S., using the common trends and common cycles approach. We investigate the presence of co-movements trying to detect a long-term stationary component, the common trend, and a short term stationary cyclical component, among international stock markets. The implications on international portfolio management are alos discussed.

In the paper monthly realized moments for stock market returns for the US, the UK, Germany and Japan are employed to assess the linkages holding across moments and markets over the period 1973-2004. In the light of the theoretical framework proposed in the paper, the results point to a progressive integration of the four stock markets, leading to increasing comovements in prices, returns, volatility and correlation. Evidence of a positive and non spurious linkage between volatility and correlation, and a trend increase in correlation coefficients over time, is also found. All the above mentioned linkages seem to be particularly strong for the US and Europe, while the persistent stagnation of the economy and the weak fundamentals over the 1990s may have been the cause of the more idiosyncratic behavior of the Japanese stock market.

These papers utilize a variety of methods, including theoretical, empirical and qualitative to highlight a range of issues across the region. Several papers offer combinations of these different categories and among the empirical papers, there are a wide variety of datasets analyzed. While China does play a significant part in the analysis of five of the papers in this volume (this is to be expected given its importance in the region), a host of other countries are also considered. This ensures the volume is truly international in its scope. These papers each serve to contribute to the knowledge on a particular issue related to the financial markets within this region and for this volume, three main issues have been identified: integration, innovation and challenges.

Recent changes in technology, along with the opening up of many regions previously closed to investment, have led to explosive growth in the international movement of capital. Flows from foreign direct investment and debt and equity financing can bring countries substantial gains by augmenting local savings and by improving technology and incentives. Investing companies acquire market access, lower cost inputs, and opportunities for profitable introductions of production methods in the countries where they invest. But, as was underscored recently by the economic and financial crises in several Asian countries, capital flows can also bring risks. Although there is no simple explanation of the currency crisis in Asia, it is clear that fixed exchange rates and chronic deficits increased the likelihood of a breakdown. Similarly, during the 1970s, the United States and other industrial countries loaned OPEC surpluses to borrowers in Latin America. But when the U.S. Federal Reserve raised interest rates to control soaring inflation, the result was a widespread debt moratorium in Latin America as many countries throughout the region struggled to pay the high interest on their foreign loans. International Capital Flows contains recent work by eminent scholars and practitioners on the experience of capital flows to Latin America, Asia, and eastern Europe. These papers discuss the role of banks, equity markets, and foreign direct investment in international capital flows, and the risks that investors and others face with these transactions. By focusing on capital flows' productivity and determinants, and the policy issues they raise, this collection is a valuable resource for economists, policymakers, and financial market participants.

The degree of comovement across national stock markets has increased dramatically since the mid-1990s. This has overturned a stylized fact in the international portfolio diversification literature that diversifying across countries is more effective for risk reduction than diversifying across industries. We investigate if this rise in comovement is a permanent phenomenon driven by greater economic and financial integration, or a temporary effect associated with the recent stock market bubble. At the global level, our results point to the bubble. At a regional level, we find evidence of a significant rise in market integration within Europe, possibly a reflection of institutional changes such as the EMU.
