An analysis of dynamic risk in the Greater China equity markets

This study looks at the time-varying nature of systematic risk in the Greater China equity markets. The Shanghai and Shenzhen markets both have a low average systematic risk when measured against the world market. The short outbursts in systematic risk for these two markets seem to be directly related to policy shifts. The Hong Kong and Taiwan markets are more integrated with world markets and they show signs of large variations in systematic risk over time. Furthermore, conditional betas in the Shanghai and Shenzhen markets are stationary, while the Hong Kong and Taiwan betas are integrated of order one. In addition, long memory tests show that all four markets exhibit a long-run dependence in their conditional betas. While the two mainland China market betas are covariance stationary, the Hong Kong and Taiwan betas are not.     

Asset Price Bubbles: Existence,Persistence and Migration

Econometric tests are performed for the detection and migration of asset‐price bubbles in the housing, currency and stock markets of seven countries. This set of countries includes both developed and emerging economies that have good historical data on housing prices. Our empirical results suggest that this type of exuberant behaviour in prices occurs more frequently in the housing market than in the currency and stock markets. Additionally, we find significant evidence of bubble migration across markets within some of the studied countries.     

Testing contagion of the 1997–98 crisis in Asian stock markets with structural breaks and incubation periods

This study tests for the existence of financial contagion, using a method that allows an incubation period before contagion takes effect. We define contagion as an increase in cross-market linkages following shocks. With daily data on Asian stock markets during the 1997–98 crisis, we find significant upward shifts in the linkages between the Asian markets of both crisis and non-crisis countries. The upward shifts are maintained even after controlling for heteroskedasticity and common world and regional factors, providing strong evidence for financial contagion.     

基于金融周期视角下股票市场的联动效应研究

世界经济全球化已成为趋势,发达经济体的股市之间以及发达经济体与新兴经济体股市之间的联动性也在经济全球化的趋势中更加紧密。各国金融领域以及金融市场间的快速融合,不断形成统一规范的金融行为准则,也使得全球金融周期性特征越来越明显。文章选取世界五个主要股票市场指数为研究对象,按照已有研究对全球金融周期的划分,将该样本区间分成了繁荣期、衰退期和正常期三个阶段,然后基于这三个阶段分析了在不同金融周期五国股票市场指数收益率联动效应。基于实证研究结论,认为美国和欧洲股市联动性较强,与亚洲股市联动性相对较弱,且美国和中国股市之间联动性最弱,基本捕捉不到下尾相关。相关实证结论有利于国际投资者的投资组合管理,也有助于各国股票市场的风险规避。     

Why are currency crises contagious? A comparison of the Latin American Crisis of 1994–1995 and the Asian Crisis of 1997–1998

Why Are Currency Crises Contagious? A Comparison of the Latin American Crisis of 1994–1995 and the Asian Crisis of 1997–1998.—This paper analyzes three channels through which currency crises are transmitted between countries: contagion based on unsustainable economic fundamentals; contagion resulting from herding behaviour in financial markets; contagion induced by close trade integration. The presented model that links currency crises with these three types of contagion is employed to analyze the transmission of the Mexican crisis in 1994–1995 and the Thai crisis in 1997 to other emerging economies. The empirical results show that, first, the most important contagion channels were based on close financial and trade integration rather than on the weakness of macroeconomic fundamentals. Second, the vulnerability to capital flow reversals and weak financial sectors made countries particularly prone to a currency crisis, while external imbalances and currency misalignments were much less important.

Contagion in the stock markets: The Asian financial crisis revisited

This paper presents empirical evidence of herding contagion in the stock markets during the 1997 Asian financial crisis, above and beyond macroeconomic fundamental driven co-movements. We analyze the cross-country time-varying correlation coefficients among the stock prices for the countries of Thailand, Malaysia, Indonesia, Korea, and the Philippines, between crisis and tranquil periods. Macromodels are constructed and implemented to capture the pure contagion effects on the markets. After controlling for the economic fundamentals for the five countries, the paper finds strong evidence of herding contagion.     

High‐Frequency Contagion of Currency Crises in Asia*

Using daily data from the Asian currency crisis, the present paper examines high‐frequency contagion effects among six Asian countries. The ‘origin’ (of exchange rate depreciation, or decline in stock prices) and the ‘affected’ (currencies, or stock prices) in the daily spillover relationship were defined and identified. Indonesia is found to be the main origin country, affecting exchange rates of other countries. Contrary to conventional wisdom, evidence of high‐frequency crisis spillover from the Thai exchange rate to other currencies was weak at best. There exists a high‐frequency contagion in stock markets among East Asian countries. Contagion coefficients are positively correlated with trade indices, indicating that investors lower their financial assessment of a country that has trade linkage to a crisis origin country within days, if not hours, of a shock.

Global Financial Crises and Time‐Varying Volatility Comovement in World Equity Markets

This paper studies volatility comovement in world equity markets between 1994 and 2008. Global volatility factors are extracted from a panel of monthly volatility proxies relating to 25 developed and 20 emerging stock markets. A dynamic factor model (FM) is estimated using two‐year rolling‐window regressions. The FM's time‐varying variance shares of global factors map variations in volatility comovement over time and across countries. The results indicate that global volatility linkages are significantly stronger during financial crisis periods in Asia (1997‐1998), Brazil (1999), Russia (1998) and the United States (2000, 2007‐2008). Emerging markets are weakly synchronised with world volatility in comparison with developed markets. In particular, emerging market comovement is significantly lower than developed market comovement during the Asian and US sub‐prime crises. This suggests a degree of decoupling of emerging markets from the global drivers of volatility during these periods.     

The current global financial crisis: Do Asian stock markets show contagion or interdependence effects?

In the framework of the current global economic crisis, a pertinent question is whether the world economies are suffering from contagion or interdependence effects. With its origins in the US sub-prime mortgage market crisis starting at the end of 2007, when a loss of confidence by investors in the value of securitized mortgages resulted in a liquidity crisis, hard-hitting the banking system and rapidly spreading into the financial markets, the effects of the crisis were automatically reflected in the rest of the world economies. These effects become more severe as the rest of the world is facing economic and financial instability. Therefore, the American shock can be seen as the trigger that revealed the other economies’ own financial problems. The main finding of this paper shows that the US stock markets are not generating contagious effects into the Asian stock markets. However, strong evidence of volatility transmission derived from these economies’ interlinkages has been detected.     

Contagion and Global Financial Crises: Lessons from Nine Crisis Episodes

Episodes of extraordinary turbulence in global financial markets are examined during nine crises ranging from the Asian crisis in 1997–98 to the recent European debt crisis of 2010–13. After dating each crisis using a regime switching model, the analysis focuses on changes in the dependence structures of equity markets through correlation, coskewness and covolatility to address a range of hypotheses regarding contagion transmission. The results show that the great recession is a true global financial crisis. Finance linkages are more likely to result in crisis transmission than trade and emerging market crises transmit unexpectedly, particularly to developed markets.     

Real Exchange Rates, Valuation Effects and Growth in Emerging Markets

We compare the relationship between net capital inflows, real exchange rate movements and growth for twenty emerging markets and twelve developed countries over the period 1985–2004. In developed countries low real exchange rates are associated with faster growth, but in emerging markets depreciations depress growth, even outside crisis periods, and are closely correlated with declines or reversals in net capital inflows. To investigate valuation effects of currency movements, we construct debt-weighted real exchange rate indices for emerging markets, which are more closely correlated with growth than trade-weighted indices.     

German,US and Central and Eastern European Stock Market Integration

This paper examines the long-term linkages between seven Central and Eastern European (CEE) emerging stock markets and two developed stock markets, namely the German and the US markets. The stability of the long-run relationships is studied using recursive cointegration analysis. The results reveal that the financial linkages between the CEE markets and the world markets increased with the beginning of the EU accession process. Furthermore, the application of the Gonzalo and Granger (J Bus Econ Stat 13:27–35, 1995) methodology indicates that the examined stock markets are partially integrated, while there is also evidence that the emerging stock markets of Central and Eastern Europe except for Estonia together with the German and the US stock markets, have a significant common permanent component, which drives this system of stock exchanges in the long run. Finally, it is worthwhile to note that the global financial crisis of 2007–2009 caused a slowdown in the convergence process. In addition we find evidence that the Slovenian stock market exhibits a moderate increase in the transitory component and this may be attributed to the Slovenian full membership in the euro area.     

Cross‐border Mergers and Acquisitions and Financial Development: Evidence from Emerging Asia

This paper examines the relationship between cross‐border mergers and acquisitions (M&A) and financial development in emerging Asian economies. Bilateral cross‐border M&A data for nine emerging Asian economies covering 2000–2009 are analyzed with a sample selection model and a panel data model. The estimation results show that although the banking sector still plays a crucial role in facilitating cross‐border M&A, the role of equity markets has increased in importance because, in addition to cash, the issuance of common stock and the exchange of stocks have become popular forms of payment for M&A deals. Because of the relatively thin market, the primary corporate bond market plays a limited role in supporting cross‐border M&A, which is in contrast to the primary public bond market. However, for the secondary market, the corporate bond market is more effective in facilitating cross‐border M&A. The results also show that financial development in terms of stock and bond markets in their home countries tends to become more important when the target firms reside in more developed countries. In addition to financial development, the paper shows that most cross‐border M&A are invested in technology‐related and resource‐based industries while cheap labor industries are relatively less attractive.     

基于Copula-GARCH模型的原油市场和股票市场相关性研究

由于原油市场和股票市场之间的联动性日益增强,因此研究两个市场之间的关联特征,分析原油价格波动对股市的影响,有助于规避风险,保证经济持续平稳地增长.采用Copula-GARCH模型对WTI原油价格的收益率序列和NASDAQ股指的收益率序列进行实证分析.结果表明,GARCH(1,1)-t模型拟合两个序列的条件边缘分布效果最好,时变SJC Copula模型比常相关Copula模型能更好地刻画两个市场之间的相关关系.两个收益率序列之间存在正的相关关系,且相关关系具有时变性,相关结构具有一定的不对称性,上尾相关系数小于下尾相关系数,即两个市场同时出现价格极端下跌的可能性更大.这为中国金融市场风险管理,规避油价波动对股市的冲击提供一定的参考依据.     

Stock market uncertainty and uncovered equity parity deviation: Evidence from Asia

Recently, many empirical studies document that a country's stock market performance relative to the US and its local currency units per US dollar tend to move in opposite direction over the short run, also known as the uncovered equity parity (UEP) condition. However, those studies have applied only to advanced economies to date. This study conducted the same tests to a sample of 18 Asian economies. To one's surprise, we found that the UEP condition reverses its sign among Asian currencies. In addition, measures of stock market uncertainty are suggested as a potential driving force behind this UEP reversal for Asian economies. This surprising result suggests that there might be other mechanisms behind the joint dynamics of equity and currency returns than the portfolio rebalancing caused by incomplete foreign exchange risk hedging. The reasoning is that Asian foreign exchange (FX) markets are even more subject to incomplete foreign exchange risk hedging. Thus, one should expect even stronger UEP evidence from Asian currency markets if the portfolio rebalancing mechanism was the only force at play.     

基于在岸金融市场视角的日元国际化进程与启示

最近几年,日元国际化程度不见提高,反而不断被边缘化,成为国际经济活动中的非主流货币。为此,文章从微观角度研究日本国内金融市场对日元国际化进程的支持力度。研究发现,受国内经济长期衰退影响,日本股票市场表现不及其他发达市场;其债券市场发展不平衡,国债市场独大,公司债券市场萎靡,并且资本项目开放不完全限制了债券市场发展;其衍生品市场也缺乏国际竞争力。换言之,日本在岸金融市场发展直接制约了日元国际化进程。     

Efficiency,Cointegration and Contagion in Equity Markets: Evidence from China,Japan and South Korea*

This paper empirically examines whether three East Asian stock markets, namely, those of China, Japan and South Korea, are individually and/or jointly efficient, and whether contagion exists between the cointegrated markets. While individual market efficiency is examined through testing for the random walk hypothesis, joint market efficiency is examined through testing for cointegration and contagion. The present study finds that the hypothesis of individual market efficiency is strongly rejected for the Chinese stock market, but not for the Japanese and the South Korean stock markets. However, when testing for cointegration, market efficiency is strongly rejected for all these markets. We take a simple case of contagion and find that although there is a long‐term relationship among the three markets, the contagion hypothesis cannot be rejected only between Japanese and South Korean stock markets, indicating short‐run portfolio diversification benefits from these two markets.     

Proposal for a common currency among rich democracies

This paper proposes the creation of a common currency for the industrialized democracies, notably the United States, the European Union, and Japan. A common currency implies a common monetary policy; institutional arrangements for which are discussed. The rationale rests on the assumption that asymmetrical financial shocks will become more important than asymmetrical real shocks for these large, diversified economies, and that one of the growing sources of financial shocks will be changing expectations about exchange rate movements among national currencies. These financial shocks will in turn disturb real economies, such that flexible exchange rates among major currencies will increasingly become sources of shock more than shock absorbers. Such a common currency would also make it much easier for emerging markets to frame their monetary and exchange rate policies.     

Financial Liberalization and Stock Market Efficiency: Causality Analysis of Emerging Markets

This paper studies the long- and short-run relationship between financial liberalization and stock market efficiency. It expands the extant body of knowledge by investigating Granger causality relationship applying mean group, common correlated effect mean group and common correlated effect pooled estimator to balanced panel data for 27 emerging markets over the period 1996–2011. We find evidence of financial liberalization Granger causes stock market efficiency, which is consistent with liberalization leads to efficiency hypothesis. Subsequently, our work makes a fresh contribution to the literature by focusing on informational efficiency of stock markets rather than financial development. Furthermore, we find that a negative long-term relationship between financial liberalization and stock return autocorrelation coexists with a positive short-term relationship between the two. The findings that financial liberalization, which has a deteriorated effect on stock market efficiency in the short-run, but positive impact in the long-run, allow us to draw an analogy similar to the J-curve hypothesis.
