Understanding the impact of marketing-related investments on market-based assets is a fundamental issue for marketers. In this study we address the relationship between product-related investments and communication-related efforts, with respect to a basic intangible market-based asset: consumer-based dimensions of brand equity. We draw from a longitudinal study of pre-purchase brand attribute data derived from consumer panels, conducted within the context of the U.S. automotive market. Brand equity dimensions are statistically related to marketing investments and contextual factors of “region of origin” and “global brand reach,” employing a seemingly unrelated regression model. The results reveal a positive effect of communication-related investments, as measured by annual advertising expenditures, on all dimensions of brand equity except luxury image. Product-related investments, as indicated by a brand's innovativeness, positively affect brand image but negatively affect perceived economy. Region of origin and global brand reach have mixed effects on the consumer-based dimensions of brand equity.

This chapter measures financial integration in 10 industries over 4 different periods. We use two robust measures of integration: (i) the Pukthuanthong and Roll (2009)’s multi-factor R-square and (ii) the Volosovych (2011)’s integration index. Both measures, based on PCA, indicate that the difference between the level of integration over the period 2009–2012 (“Post-Lehman” era) and the level of integration over the period 1994–1998 (“Post-Liberalizations” era) is relatively high. In addition, the level of financial integration across international equity markets decreased during the late 1990s. This suggests that de jure integration does not necessarily improve de facto integration. Overall, our findings give rise to a “diversification benefits-insurance benefits trade-off.”

The purpose of this paper is to investigate the short- and long-run dynamic linkages between selected cryptocurrencies, several major world currencies and major equity indices. The results show that despite sharing some common characteristics, the cryptocurrencies do not reveal any short- and long-term stochastic trends with exchange rates and/or equity returns. The dynamics of each cryptocurrency with the Chinese Yuan appears to be more turbulent than that with the other exchange rates. Each cryptocurrency appears to follow its own trend in the global financial market and is independent of the exchange rates or the global stock markets, thus making them suitable for inclusion in global investment portfolios.

The cryptocurrencies examined are Bitcoin, Dash, Ethereum, Monero, Stellar and XRP. In addition, data were collected on major exchange rates with respect to the US dollar, namely, the euro, British pound, Japanese yen and Chinese Yuan. Finally, the following major stock market indices were selected: SP500, DAX, DJIA, CAC, FTSE, NIKKEI, Hang Seng and Shanghai. The study applied vector autoregressive (VAR) model and Engle’s (2002) dynamic conditional correlation generalized autoregressive conditional heteroskedasticity (DCC-GARCH) specification.

First, it was found that cryptocurrencies do not interact with each other because their correlations are weak and do not share a common long-run path; thus they are not cointegrated. Second, impulse response analysis from the VAR models indicate different reactions of each cryptocurrency to both exchange rate and equity shocks and that cryptocurrencies appear to be isolated from market-driven shocks. Third, the ups and downs in the cryptocurrencies’ dynamic conditional correlations (from the DCC-GARCH models) indicate that all cryptocurrencies were susceptible to speculative attacks and market events.

This paper examines the dynamic linkages among the most important cryptocurrencies with major exchange rates and equity markets and, to the best of the authors’ knowledge, is the first paper to do so. Thus, interested market agents would gain valuable insights as to whether this new form of asset might be used for conducting monetary policies and portfolio construction on a global setting.

The paper contributes to the scant literature on the dynamic linkages among major cryptocurrencies and global financial assets. In general, given the differential relationships of each crypto with the equity markets, one could infer that they represent a decent short-run investment vehicle within a well-diversified, global asset portfolio (as they may increase the returns and reduce the overall risk of the portfolio).

This chapter examines dynamic connectedness among emerging Asian equity markets as well as explores their linkages vis-à-vis other major global markets. We find that international equity markets are tightly integrated. Measuring connectedness based on a generalized Vector Autoregressive (VAR) model, more than half of all total forecast error variance in equity return and volatility shocks come from other markets as opposed to country own shocks. When examining the degree of connectedness over time, we find that international stock markets have become increasingly connected, with a gentle upward trend since the Asian financial crisis (AFC) but with a rapid burst during the global financial crisis (GFC). Despite the growing importance of Asian emerging markets in the world economy, we find that their influence on advanced economies are still relatively small, with no significant increase over time. During the past decade, advanced markets have been consistently net transmitters of shocks while emerging Asian markets act as net receivers. Based on the nature of equity shock spillovers, we also find that advanced countries are still tightly connected among themselves while intraregional connectedness within Asia remains strong. By investigating whether uncertainty plays an important role in explaining the degree of stock market connectedness, we find that economic policy uncertainty (EPU) from the US is an important source of financial shock spillover for the majority of international equity markets. In contrast, US financial market uncertainty as proxied by the VIX index drives equity market spillovers only among advanced economies.

This paper uniquely aims to triangulate the effects of the COVID-19 pandemic, government financial intervention (GFI) policies and power distance (PD) culture on returns of equity indices during the COVID-19 epidemic in the world's equity markets.

The research employs panel data regression analysis using 1,937 observations from 19 developed and 42 developing countries. The data employed contain daily registered COVID-19 cases, global equity market index prices, financial intervention policies introduced by governments and Hofstede's cultural dimension measure of PD.

The authors find that investors certainly react negatively to the number of confirmed COVID-19 cases reported, that GFI policies indeed reinforce investors' expectations of policymakers' dedication to stabilize the economy during the COVID-19 pandemic and that equity investors in high PD cultures overreact to GFI news, resulting in more positive stock returns. The authors discover a difference between developed and developing countries in terms of the effect of GFI policies and PD on equity returns.

Results suggest that investors react negatively to the daily registered COVID-19 cases. The authors find that financial intervention policies introduced by governments reinforce investors' outlooks of policymakers' commitment to stabilize local stock markets during the coronavirus pandemic. The results confirm that equity market investors in PD cultures overreact to financial intervention news, thus resulting in more positive stock returns.

The paper provides three original contributions. First, it helps us to understand the single effect of the COVID-19 and financial intervention policies introduced by governments on returns of the global equity market. Second, it examines the possibility of a two-way joint effect between the COVID-19 and financial intervention policies introduced by governments and the COVID-19 and differences in countries characterized by a PD culture concerning stock market returns. Third, it investigates the possibility of a three-way interaction effect between the COVID-19 contagion, financial intervention policies introduced by governments and culture on returns of equity markets.

The authors' findings are valuable to researchers, investors and policymakers. Culture and finance scholars can now observe the role of Brown et al.'s (1988) uncertain-information hypothesis with reference to the effect of the COVID-19 and financial interventions policies introduced by governments on returns of equity markets. This is because the authors' findings underline that since investors' uncertainty declines with daily registered numbers of COVID-19 cases, the introduction of GFI policies function as a neutralizing device to re-establish investors' expectations to equilibrium. Consequently, stock market returns follow a random walk that is free from the negative effect of the COVID-19. The authors' work is likely to advise equity investors and portfolio managers about the extent to which major exogenous economic events such the outbreak of global diseases, financial interventions policies introduced by governments and differences in countries' PD culture can individually and jointly influence the return of the world's equity markets. Investors and portfolio managers can employ the authors' results as a guideline to adjust their investment strategy based on their investment decision strategy during global pandemics. Policymakers aiming to introduce financial intervention policies to stabilize their stock market returns during global pandemics can benefit from our results. They can observe the full effect of such policies during the current COVID-19, and subsequently be better prepared to choose the most effective form of financial intervention policies when the next pandemic strikes, hopefully never.

The present research study aims to explore the impact of the most recent Israeli–Palestinian conflict, which unfolded in October 2023, on global equity markets, including a wide range of both emerging and developed markets (as per the Morgan Stanley Capital Investment country classification).

The market model of event study methodology, with an estimation window of 200 days and 28-day event window (including event day, i.e. October 7, 2023), has been employed to investigate the event’s impact on the stock markets of different countries, with 24 emerging countries and 23 developed countries. The daily closing prices of the prominent indices of all 47 countries have been analyzed to examine the impact of the conflict on emerging markets, developed markets and overall global equity markets. Additionally, cross-sectional regression analysis has been performed to investigate the possible explanations for abnormal returns.

The findings of the study suggest the heterogeneous impact of the selected event on different markets. Notably, emerging markets and the overall global equity landscape exhibited substantial negative responses on the event day, as reflected in average abnormal returns of −0.47% and −0.397%, respectively. In contrast, developed markets displayed resilience, with no significant negative impact observed on the day of the event. A closer examination of individual countries revealed diverse reactions, with Poland, Egypt, Greece, Denmark and Portugal standing out for their positive or resilient market responses. Poland, in particular, demonstrated significantly positive cumulative abnormal returns (CARs) of 7.16% in the short-term and 8.59% in the long-term event windows (−7, +7 and −7, +20, respectively), emphasizing its robust performance amid the geopolitical turmoil. The study also found that, during various event windows, specific variables had a significant impact on the CARs.

The study suggests diversification and monitoring of geopolitical risks are key strategies for investors to enhance portfolio resilience during the Israeli–Palestinian conflict. This study identifies countries such as Poland, Egypt, Greece, Denmark and Portugal with positive or resilient market reactions, providing practical insights for strategic investment decisions. Key takeaways include identifying resilient markets, leveraging opportunistic strategies and navigating market dynamics during geopolitical uncertainties.

As per the authors’ thorough investigation and review of the literature, the present study is the earliest attempt to explore the short-term and long-term impact of the 2023 Israeli–Palestinian conflict on equity markets worldwide using the event study approach and cross-sectional regression analysis.

This study aims to investigate the impact of FTX bankruptcy on the global stock markets, including both the developed and emerging markets, as per the Morgan Stanley Capital Investment (MSCI) country classification.

Using the daily closing prices for leading stock market indices of all 47 countries in the MSCI market classification, comprising 23 developed markets and 24 emerging markets, the event study methodology is used to examine the impact of the event on developed markets, emerging markets and overall global equity markets.

The study finds heterogeneous effects of the event on different countries. Results indicate that overall global equity markets experienced a statistically significant positive cumulative average abnormal returns of 15.8533% in the complete event window of 28 days from t − 7 to t + 20. The authors conclude that traditional global equity markets can be used as a hedge against potential financial risk posed by unfavorable events in the cryptocurrency markets and have safe haven properties.

The study emphasizes the global financial system’s interconnectedness and the potential of traditional equity markets to hedge risks in the cryptocurrency market. The findings are relevant for investors seeking portfolio diversification and mitigating their exposure to potential risks in the cryptocurrency market.

To the best of the authors’ knowledge, the present study is the earliest attempt to comprehensively examine the impact of the bankruptcy of the world’s fourth largest cryptocurrency exchange, FTX, on the global equity markets.

The purpose of this paper is to examine the international diversification benefits of Islamic bonds (Sukuk) for equity investors in conventional stock markets. The authors compare the diversification benefits of these securities with their conventional alternatives from advanced and emerging markets. Compared to conventional bonds, Sukuk are backed by tangible assets and carry both bond and stock-like features. Furthermore, the Sharia-based limitations limit the risk in these securities as a result of ethical investing rules. The regime-based model provides insight to possible segmentation (or integration) of these securities from global markets during different market states.

Risk spillover effects across conventional and Islamic stock and bond markets are examined using a Markov regime-switching GARCH model with dynamic conditional correlations (MS-DCC-GARCH). Weekly return series for conventional (advanced and emerging) and Islamic stock and bond indices are examined within a regime-dependent specification that takes into account low, high, and extreme volatility states. The DCC are then used to establish alternative diversified portfolios formed by supplementing conventional and Islamic equities with conventional and Islamic bonds one at a time.

Asymmetric shocks are observed from conventional stocks and bonds into Islamic bonds (Sukuk). Compared to emerging market bonds, Sukuk are found to display a different pattern in the transmission of global market shocks. The analysis of dynamic correlations suggests a low degree of association between Islamic bonds and global stock markets with episodes of negative correlations observed, particularly during market crisis periods. Portfolio performance analysis suggests that Islamic bonds provide valuable diversification benefits that are not possible to obtain from conventional bonds.

This study provides comprehensive analysis of volatility interactions and dynamic correlations across Islamic and conventional markets within a regime-based framework and provides insight to whether these securities could serve as safe havens or diversifiers for global investors. The findings have significant implications for global diversification strategies, particularly during market crisis periods.

This study investigates information flow of market constituents and global indices at multi-frequencies.

The study’s findings were obtained using the Improved Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (I-CEEMDAN)-based cluster analysis executed for Rényi effective transfer entropy (RETE).

The authors find that significant negative information flows among sustainability equities (SEs) and conventional equities (CEs) at most multi-frequencies, which exacerbates diversification benefits. The information flows are mostly bi-directional, highlighting the importance of stock markets' constituents and their global indices in portfolio construction.

The authors advocate that both SE and CE markets are mostly heterogeneous, revealing some levels of markets inefficiencies.

The empirical literature on CEs is replete with several dynamics, revealing their returns behaviour for diversification purposes, leaving very little to know about the returns behaviour of SE. Wherein, an avalanche of several initiatives on Corporate Social Responsibility (CSR) enjoin firms to operate socially responsible, but investors need to have a clear reason to remain sustainable into the foreseeable future period. Accordingly, the humble desire of investors is the formation of a well-diversified portfolio and would highly demand stocks to the extent that they form a reliable portfolio, especially, amid SEs and/or CEs.

本研究擬審查多頻率的及為市場成份的信息流和全球指數。

研究人員使用基於改良完全集合經驗模態分解自適應噪聲(Improved Complete Ensemble Empirical Mode Decomposition with Adaptive Noise)的聚類分析法,取得Rényi有效轉移熵,藉此得到研究結果。

我們發現、於大部份多頻率,在持續性股票和傳統股票間有顯著的負信息流動,這會增加多樣化的益處。這些信息流大部份是雙向的,這強調了股票市場成份及其全球指數在構建投資組合上的重要性。

我們認為持續性股票市場和傳統股票市場大多為異質市場,這顯示了市場的低效率,而且這低效率的程度頗大。

關於傳統股票的實證性文獻裡是充滿了變革動力的,這顯示了它們以多樣化為目的的回報行為。這使我們對關於持續性股票的回報行為、認識變得實在太少了。於此,大量的企業社會責任的新措施不斷提醒各公司、要本著企業社會責任的理念去營運;但投資者需清晰明白他們為何需在可見的將來保持可持續性。因此,他們卑微的願望是一個較好的多樣化投資組合得以形成,故此他們高度要求股票要有組成可靠投資組合的性質和能力,特別是在持續性股票和/或傳統股票當中。

This paper investigates the global financial integration of the Gulf Cooperation Council markets, which is important for financial economists, global investors and policymakers.

The first step is to estimate a benchmark one-factor model and multifactor models over the entire sample period to obtain the time-invariant global integration estimates for the Gulf Cooperation Council markets. Because the global integration of the Gulf Cooperation Council markets may be time varying, the second step is to use 24-month rolling regressions to estimate the time-varying integration estimates. To explicitly test for structural breaks in global integration, this study applies a supremum Wald test to endogenously search for structural breaks.

Empirically, consistent evidence suggests that the Gulf Cooperation Council markets are increasingly integrated with international equity markets at different levels of financial development and from different regions. However, compared to other emerging and frontier markets, the global integration of the Gulf Cooperation Council markets is still relatively low, suggesting that these markets still offer significant diversification benefits for global investors.

This study contributes to the literature by systematically investigating the global integration of the Gulf Cooperation Council markets with monthly data (to account for the gradual information diffusion in international equity markets) and a longer sample period (to more robustly identify the trend in the global integration).
