The Asian flu and Russian virus: the international transmission of crises in firm-level data

This paper examines how the Asian and Russian crises affected different types of firms around the world. It constructs a new data set of financial statistics, industry information, geographic data, and stock returns for over 10?000 companies in 46 countries. Results show that firms competing with exports from the crisis countries, or with direct sales exposure to the crisis countries, had significantly lower abnormal stock returns. Firms with higher debt ratios, however, did not experience lower abnormal returns. Country-specific effects, although important determinants of company stock returns, are generally less important than firm-specific characteristics. These results suggest that trade channels are important factors determining how crises are transmitted internationally.     

The Effect of 2008 Crisis on the Volatility Spillovers among Six Major Markets

The scope of this paper is to determine whether global stock markets function differently under conditions of economic crisis by measuring volatility spillovers between six major markets, namely the US, the UK, Germany, Spain, Turkey, and Greece. We examine the volatility spillover effects of the 2008 US financial crisis to these six major markets using daily stock returns from January 2003 to December 2014, before, during, and after the 2008 financial crisis. We combine the Diebold and Yilmaz methodology with the stochastic volatility model of Taylor implemented through the sequential Efficient Importance Sampling method of Richard and Zhang to obtain variance decompositions derived from an estimated vector autoregressive model. The empirical findings suggest that stock markets tend to show increased volatility spillovers during the crisis period, thus resulting in lesser diversification benefits for investors.     

Global Volatility and Forex Returns in East Asia*

During 2001–2010, increases in mature market volatility were associated with declines in forex returns for East Asian economies, consistent with an overall ‘flight to safety’ effect. Estimates from GARCH models suggest that a 10 percentage point increase in mature market equity volatility generated an exchange rate depreciation of up to 3/4 percent. This sensitivity rose during a more tranquil subsample for some countries, reflecting their greater integration with global financial markets. Long‐run forex volatility increased in Asian economies after 2008, reflecting the global reach of the financial crisis in mature markets. Unconditional standard deviations estimated from these models provide operational measures of ‘long‐term’ and ‘excess’ volatility in forex markets.

Did Investors Herd during the Financial Crisis? Evidence from the US Financial Industry

We examine the herding behavior of investors in the US financial industry, especially commercial banks, S&Ls, investment and insurance firms during global financial crisis of 2008 towards own sub‐sector and market consensus using augmented cross sectional absolute deviation of returns (CSAD) model. After distinguishing between fundamental and non‐fundamental information, we find a greater influence of global financial crisis on spurious herding for commercial and investment banks, and such herding increases in the down market and with conditional volatility of returns, but adverse herding is prevalent among investors during normal period in response to fundamental information. We also find that herding intensity on fundamental information is relatively high with market consensus for all financial institutions except insurance firms in high volatility regime, and intentional herding is only significant and limited to S&Ls and investment banks in high volatility regime. Our findings suggest limited spillover effects of herding when investors face non‐fundamental information.     

Industry and country factors in emerging market returns: Did the Asian crisis make a difference?

Should investors diversify across emerging stock markets or across industries to achieve improvements in their risk–return tradeoffs especially during financial crisis periods? We examine the issue using individual firm data from a selection of emerging markets and including the period of the 1997 Asian financial crisis. We find that country effects were the dominant force behind the low co-movements among emerging stock market returns. There is evidence of increased industry effects beginning at the time of the Asian financial crisis, but this may have been a temporary phenomenon associated with contagion effects during the crisis.     

COVID-19 and business renewal: Lessons and insights from the global airline industry

The emergence of the COVID-19 pandemic has adversely affected the fortunes of multiple companies around the globe. Accordingly, questions are increasingly being asked about how organizations can revitalize during and after a crisis. Yet, we have limited understanding of how organizations renew themselves during crises over time. We explore this question through the lens and examination of two South-Asian airlines: Pakistan International Airlines and Sri Lankan Airlines. The cases offer important insights into the reasons behind underperformance of state-controlled enterprises and renewal activities. We shed light on strategic renewal (SR) in the wake of increasing liberalization and deregulations in the global airline industry. To this end, we propose a four-stage approach towards renewing such underperforming organizations to respond effectively to black swan events and external shocks.     

Volatility spillover and hedging effectiveness among China and emerging Asian Islamic equity indexes

We study the volatility spillover between China and Asian Islamic stock markets. We use a sample of six Islamic MSCI indices from the Asian region, namely China, India, Malaysia, Indonesia, Korea and Thailand obtained from MSCI (Morgan Stanley Capital International). In this paper we analyze the importance of considering spillover effects between emerging Asian Islamic indexes based on the Bivariate VARMA-BEKK-AGARCH model of McAleer et al. (2009), which includes spillover and asymmetric effects. We compute after the effectiveness of portfolio diversification based on the conditional volatility of returns series. Results show a significant positive and negative return spillover from China to selected Asian Islamic stock market and bidirectional volatility spillovers between China, Korea and Thailand Islamic market showing evidence of short-term predictability on Islamic Chinese stock market movements. However there is no short term volatility persistence in India, Indonesia and Malaysia. GARCH results show no persistence in volatility spillover effect in long term from Chinese to Indian, Indonesian and Korean Islamic stock market. Our findings are beneficial for international portfolio diversification for policy makers and investors since the results of portfolio management and hedging effectiveness ratio are different to previous studies.     

Does High Service Quality Reduce Risk or Create Idiosyncratic Returns?

This article explores the impact of service quality on idiosyncratic returns, idiosyncratic risk (nonsystematic risk), and beta (systematic risk). Service quality was derived from the airline quality rating, and three dependent variables were calculated by the Fama–French four-factor model. The data includes 1,512 monthly records from 1997 to 2006, across 21 airlines. Multiple regression and vector autoregressive models were applied to test relationships among all, low-cost, and non-low-cost airlines. The study found that service quality has a positive impact on idiosyncratic returns in non-low-cost airlines; non-low-cost airlines are less affected by changes in the external environment.     

FX Market Returns and Their Relationship to Investor Fear

This note examines the relationship between changes in levels of investor fear (measured by the implied volatility index) and foreign exchange market returns. Our empirical results indicate a negative relationship between daily returns on high‐interest rate (investing) currencies and changes in the implied volatility index, while the association is positive for low‐interest rate (funding) currencies. That is, investing (funding) currencies tends to depreciate (appreciate) when investor fear increases. A sequential breakpoint test identifies a significant change in this relationship in the period following the 2008 collapse of Lehman Brothers, and another in 2012 following the resolution of the European sovereign debt crisis, which suggests that the relationship is linked to financial system liquidity. During the crisis period, currency returns are much more sensitive to changes in investor fear, and this is particularly so for funding currencies that are perceived to present a safe‐haven. The results have important implications for international finance, and those looking to speculate via the carry trade.     

The roles of news and volatility in stock market correlations during the global financial crisis

The global financial crisis has again brought the interdependencies of international financial markets to the fore, particularly during times of financial crises. This paper explores the relative roles of news and volatility in explaining the changes in correlations between national stock markets during the global financial crisis. Our results show that the majority of the correlations are more strongly explained by volatility rather than news. However as the global financial crisis evolves the relative role of news grows in importance.     

One country,two systems? The heavy-tailedness of Chinese A- and H- share markets

Chinese A- and H– share markets operate in different institutional environments (emerging/developing v.s. developed) and thus may have different tail risk properties. This paper focuses on the analysis of heavy-tailedness properties of these two markets using recently developed robust inference methods. The equality of tail indices of returns for A and H dual-listed companies cannot be rejected, and some A- and H– share returns may have infinite second moments. Their heavy-tailedness properties did not change significantly with respect to the 2008 financial crisis and the date when the corresponding company starts to be dual-listed.     

Are environmental social governance equity indices a better choice for investors? An Asian perspective

This article examines the risk and return profiles of stock indices composed of companies meeting environmental, social and governance (ESG) screening criteria [such as the Dow Jones Sustainability Indices (DJSI)] and conventional composite indices of eight Asian countries from 2002 to 2014. The results indicate that there are no significant differences in the returns or risk‐adjusted returns between the ESG indices and the composite indices within countries. The results do reveal that the market volatility of the ESG indices is higher than the market volatility of the conventional indices. Market betas of DJSI and ESG equity indices are significantly lower than betas of the composite equity indices. The overall results indicate that the performance of ESG equity indices of many Asian countries is similar to the performance of conventional indices, suggesting that investors can pursue socially responsible investing objectives without a material difference in portfolio performance from conventional investing.

The Breakdown of Idiosyncratic Volatility Into Expected and Unexpected Components and Its Effects on Stock Returns in Brazil

Based on studies of idiosyncratic volatility developed in the recent literature, this study analyzes its relation with expected returns through the breakdown of idiosyncratic volatility in the Brazilian stock market and presents evidence of the importance of expected idiosyncratic volatility for asset pricing. We study the impact of the expected and unexpected components of idiosyncratic volatility on the returns of shares listed on the BOVESPA between 2004 and 2011. The results show a strong positive and significant relation between expected idiosyncratic volatility and returns. This evidence is highlighted when we use unexpected idiosyncratic volatility to control for unexpected returns. Additional robustness tests, controlling for size and momentum effects, also have positive and significant coefficients, corroborating previous findings.     

The Effect of Sport Sponsorship Programs of Various Sport Events on Stock Price Behavior During a Sport Event

This paper examines sporting event's spillover effect to investor's behavior through event study analysis using the GARCH (p,q) model, focusing on the stock price effects of a sport sponsorship program during and after a sporting event. Studying stock price behavior during a sporting event is attempted for the first time in the marketing and sponsorship literature. First, we provide some summary points from the review of 40 research works and interpretive claims, based on a conceptual and theoretical framework. Second, we consider daily stock returns of 28 listed companies that have sponsored 15 major sports events during the period 2000–2009, in order to examine the effect of major sporting events on sponsors’ stock returns and volatility. The three research hypotheses are supported. Research results show that stock returns and volatility changed significantly during and after the sporting event compared to pre-event period. Results show that stock price effects caused by sports events’ sponsorship programs are firm-specific, as well as sporting event-specific. The findings of this study are of high value for promotion managers as it allows them to become more critically aware of the practical wisdom of sporting events.

Did corporate governance safeguard investor interest in the global financial crisis? Evidence from Hong Kong SAR

The global financial crisis of 2008 aroused renewed interest in the effectiveness of corporate governance mechanisms to safeguard investor interests. In this paper, we measure the effects of the crisis from 2008 to 2009 on the share performance of 976 companies listed on the Hong Kong Stock Exchange in the Hong Kong SAR and examine the link between share performance and corporate governance mechanisms. Our results present evidence that firms with a higher proportion of independent directors and a greater concentration of ownership had lower share performance, but lower price volatility, during the global financial crisis. These results suggest that no single corporate governance mechanism is fit for all economic environments and time frames. To strengthen investors' confidence, companies should enhance the efficiency and adaptability of their governance mechanisms in turbulent times.     

金融危机冲击下上市公司融资约束与融资决策的实证研究

以1998-2009年度制造业上市公司为样本,检验金融危机冲击下融资约束对上市公司融资决策的影响。实证研究结果表明:融资约束程度显著影响了上市公司外源融资能力,特别是外源权益资本的融资能力;同时,在金融危机冲击下融资约束严重的上市公司受到外源融资溢价及外源融资可获得性下降的影响,更倾向于内源融资和负债融资。可见,融资约束严重的上市公司在面临金融危机冲击时,具有较高的脆弱性。     

Assessing the Impact of Crude Oil Price and Investor Sentiment on Islamic Indices: Subprime Crisis

This article attempts to shed light on the impact of oil prices, investor sentiment, and conventional index on 11 Islamic indices, particularly during the subprime financial crisis and the oil crisis. Empirical evidence suggests that the Malaysian and Indonesian Islamic indices are very much affected by the oil volatility. Estimation results of the BEKK-GARCH model reveal that the pessimistic sentiment during the subprime crisis is transmitted to Islamic indices, suggesting the herding contagion. The authors' finding indicates that investors can use VIX investor sentiment as an indicator to predict Islamic returns volatility. In addition, the authors find that the oil shock has spilled into Islamic indices. The time-varying correlation indicates strong evidence of the contagion effect of crude oil and investor sentiment measure to Islamic indices during the oil shock and U.S. financial crisis period of 2008–2009.
