The purpose of this study is to investigate the impact of policy uncertainty on firm performance and to examine how the different cultural societies deal with the policy-induced uncertainty.

The authors use data of European non-financial firms to extend the growing literature on policy uncertainty, firm performance and national culture. The authors consider financial as well as market proxies to measure firm performance and use Hofstede's cultural dimensions as a proxy for national culture. The authors apply the generalized method of moments (GMM-system) regression technique on a dataset of 702 non-financial European firms, listed during the period 2002–2018.

The authors find overwhelming evidence that policy uncertainty reduces the performance of the European firms; however, cultural differences among different European countries moderate the impact of policy uncertainty on the financial as well as the market performance of the firms. The results of this study show that European cultures with high power distance, individualism, masculinity and indulgence efficiently deal with the economic policy uncertainty. While the European societies with high uncertainty avoidance fail to cope with policy-induced uncertainty. The results are robust to different regression models, alternate proxies of firm performance and endogeneity issues.

The authors argue that policy uncertainty increases information asymmetry and decreases firm performance, therefore, the policymakers shall be considerate of the consequences of the policy-induced uncertainty in the society and business arena that would not only adversely affect the firms but also the economy.

To the best of the authors' knowledge, this is the first study that investigates the role of national culture on the relationship between policy uncertainty and firm performance in the European context.

The purpose of this study is to investigate the moderating impact of corporate governance (CG) on the relationship between economic policy uncertainty (EPU) and the sustainable growth (SG) of Chinese firms.

The study collects data of 975 Chinese non-financial listed firms for the period from 2010 to 2017. The study measures SG using a comprehensive index based on nine financial indicators and applies industry and year fixed effects regression to investigate the direct and moderating impact of CG on the relationship between EPU and SG of Chinese firms.

The results of the study explain that EPU negatively affects SG, while concentrated ownership, board independence and board gender diversity (BGD) positively contribute to the SG of the Chinese firms. The results also explain that concentrated ownership and BGD reduce the negative impact of EPU on the SG of the Chinese firms.

The study considers only non-financial firms; therefore, the results of this study cannot be generalized for financial firms. Future research can be carried out while considering financial firms as a unit of analysis.

The investigation of the negative impact of policy uncertainty on SG is essential for the government and policymakers to devise policies to reduce uncertainty. The investigation of the moderating effect of CG enriches the literature on corporates’ response to policy uncertainty. It provides valuable insights for corporates regarding CG mechanisms to attain SG.

To the best of the authors’ knowledge, this is the first study that investigates the moderating impact of CG on the SG of Chinese firms using an index-based measurement of SG.

This paper examines the influence of investment opportunities on firm performance and evaluates corporate governance practices in the United Arab Emirates (UAE) to determine whether corporate governance quality moderates that influence.

A fixed-effects regression was employed to examine the influence of investment opportunities on firm performance and the role of corporate governance quality as a moderator for all listed firms on the Abu Dhabi Stock Exchange (ADX) and the Dubai Financial Market (DFM). We examined 501 firm-year observations for the period when the corporate governance code in the UAE was coming into force, from 2008 to 2012.

The regression results indicate that investment opportunities have a negative influence on firm performance. The corporate governance index used here shows that the level of corporate governance practiced in the UAE is weak. We also find that strong corporate governance ameliorates the negative influence of investment opportunities, which supports our hypotheses. The sub-indices of corporate governance that matter the most for moderating investment opportunities are board functioning and ethics.

The results of this paper reflect the need to examine corporate governance in the context of the external environment represented by investment opportunities in our study. The findings could raise awareness of the importance of strong corporate governance practices, not only to directly improve firm performance but also through its influence on external variables. Legislators, regulators and other interested parties could use these results to examine practices in the UAE following the implementation of the corporate governance code.

This study contributes to the literature by evaluating the role that corporate governance quality and its components could play in firm performance and indirectly moderating other external factors (such as investment opportunities).

The purpose of this paper is to investigate whether liquidity risk (i.e. the returns’ vulnerability to the unexpected changes in overall market liquidity) is a priced risk factor in China. Moreover, it investigates the potential role of a stock’s information quality in reducing its liquidity risk during the period of post-non-tradable shares reforms in China.

The authors collect data of all the A-share issuing firms listed either on the Shanghai Stock Exchange or Shenzhen Stock Exchange during the period 2006–2016. The authors perform two-stage cross-sectional regression testing. First, the authors perform firm-specific time-series regressions of excess returns over Fama–French’s three-factor model and a liquidity factor. Second, to test whether firm-specific liquidity risk is a priced risk factor, the authors apply Fama and MacBeth’s regressions.

Firm-level asset pricing tests provide substantial evidence for market pricing of liquidity risk in China. The authors find a significant negative association between information quality and liquidity risk. The authors also find that the reduction in liquidity risk induced by better information quality is substantial enough to reduce required returns. These findings are robust to alternative measures of liquidity risk and information quality.

The study underscores that a policy initiative to enhance the information environment can significantly reduce the market volatility in China.

To the best of authors’ knowledge, this is the first study that considers the Shanghai Stock Exchange as well as Shenzhen Stock Exchange to investigate market pricing of liquidity risk in China.

The purpose of this study is to explain the adjustment rate toward the target capital structure of Chinese nonfinancial listed firms and to investigate the impacts of the split-share reforms (2005–2006) on the capital structure adjustment rate.

The authors control for the unobserved heterogeneity and the fractional nature of the adjustment rate by applying an unbiased dynamic panel fractional estimator on the unbalanced panel data of 27,545 firm-year observations of Chinese nonfinancial firms listed during 1998–2015.

The authors find that Chinese firms adjust at an annual rate of 19–27% to reach their capital structure targets. The authors also find a positive impact of the split-share reforms on the adjustment rates of Chinese nonfinancial firms toward their target capital structure. Split-share reforms also helped Chinese firms to increase the use of equity financing in their capital structure.

The authors argue that the government should strengthen capital markets to enable easy access to more financing options so that Chinese firms can acquire cheaper external financing.

To the best of authors' knowledge, this is the first study that applies an unbiased dynamic panel fractional estimator on an extended data set of 27,545 firm-year observations of Chinese nonfinancial firms listed during 1998–2015.

This study aims to investigate the impact of managerial power distance on the corporate sustainability performance of Chinese firms and to explore the regulatory role of corporate digitalization in the Chinese capital market.

The study collects data from 2,632 A-share Chinese non-financial firms listed on Shanghai and Shenzhen stock exchanges during the period from 2010 to 2020. The authors apply different panel data regression techniques (fixed effects, GMM-System) to investigate the impact of managerial power distance on corporate sustainability performance and to explore the regulatory role of corporate digitalization in the Chinese capital market.

The results of the study show a positive relationship between high managerial power distance and the sustainability performance of Chinese non-financial firms. This positive relationship is particularly pronounced in Chinese state-owned enterprises (SOEs). The results also show that corporate digitalization increases the sustainability performance of Chinese firms. Further, corporate digitalization weakens the positive relationship between high-power distance and the sustainability performance of Chinese firms. These results are robust to alternate sustainability performance measures and various regression techniques.

To the best of the authors' knowledge, this is the first study that investigates the regulating impact of corporate digitalization on the relationship between managerial power distance and corporate sustainability performance in China.

The purpose of this study is to develop an Islamic Banking Index representing the Islamic banking model and to investigate its impact on the performance of Islamic and conventional banks. This study also analyzes the impact of Islamic financial development on bank performance.

The authors collected the data from 23 countries for the period from 2010 to 2018 and developed a composite Islamic Banking Index. The authors applied the generalized method of moments on 3,542 bank-year observations for both Islamic and conventional banks to analyze the impact of the Islamic Banking Index on bank performance. The results of the study are robust to time-fixed effects, country-level time-varying factors and endogeneity issues.

The authors found that Islamic Banking Index positively contributes to the return on assets (ROAit) of Islamic banks only. This impact becomes highly significant in countries with comparatively higher Islamic financial development. This finding suggests that the Islamic financial development in a country provides a supportive operating environment to Islamic banks and increases their performance. The authors also found that Islamic Banking Index positively contributes to the return on equity (ROEit) of both types of banks.

The authors argue that moving away from interest-based products and focusing more on diversified portfolios can boost the performance of both types of banks without increasing their risk levels.

To the best of the authors’ knowledge, this is the first study that develops a composite Islamic Banking Index based on differentiating factors of the Islamic banking model and investigates the impact of Islamic Banking Index and Islamic financial development on bank performance.

The purpose of this paper is to find out firm, industry, and country level determinants of capital structure of Pakistani listed non-financial firms.

The authors use a fixed effects panel data model over a 39 years (1972-2010) unbalanced panel data of Pakistani non-financial listed firms to determine the factors that influence capital structure of these firms.

The authors find that Pakistani firms prefer retained earnings to finance their business projects, and debt is easily available for experienced firms. Moreover, socio-economic collusive networks, poor corporate governance mechanism along with weak legal system provide these firms an opportunity to pass on their risk to the creditors (banks).

The data set does not contain factors characterizing inter-industry heterogeneity, therefore, the authors use mean industry leverage and mean industry profitability to explore if any relationship exists between leverage of firms, and their respective industry leverage/profitability.

Pakistani non-financial firms are highly leveraged increasing their probability to face financial distress in erratic economic conditions. As such, the policy makers need to develop capital markets of Pakistan to enable a resilient corporate capital structure. Further, erratic economic conditions of Pakistan create uncertain business environment yielding short-term opportunities and to finance them Pakistani firms use short-term debt as a main financing source. The policy makers need to improve corporate governance mechanism and strengthen legal system that will go a long way to develop Pakistani capital market on sound and sustainable footing.

This is the first study that uses an extended number of variables and discovers financial behavior of firms in a bank-based economy having limited financing options, and facing erratic economic conditions.

The purpose of this study is to explain the adjustment rate made to target capital structures by listed non-financial firms in Pakistan during the courses of their life cycles and to determine what factors influence their adjustment rates.

The study used multivariate analysis to classify 39 years (1972-2010) of unbalanced panel data from listed non-financial Pakistani firms in terms of their growth, maturity and decline stages. Further, it used a fixed-effects panel data model to determine the factors that influence capital structure and adjustment rates during the life-cycle stages of firms.

The study observed a low–high–low leverage pattern during the growth, maturity and decline stages of businesses in line with tradeoff theory. Furthermore, the study observed an adjustment rate for growing firms of between 49.3-37.9 per cent, for mature firms of between 35.5-17.5 per cent and for declining firms of between 22.2-15.1 per cent toward their respective leverage targets. Furthermore, it was found that growing firms have higher leverage adjustment rates because, by having more investment opportunities, these firms can alter their capital structures easily by changing the composition of their new issues.

Erratic economic conditions in Pakistan have created an uncertain business environment. Therefore, even mature Pakistani firms remain skeptical about the sustainability of positive trends among current economic indicators. Furthermore, to avoid uncertainty, Pakistani firms grab short-term opportunities by using quickly available short-term debt as a main financing source. Government should introduce long-term policies that will stabilize the business environment and strengthen the financial, as well as the judicial, institutions of the country so that these firms may benefit from long-term investment opportunities and access more options for raising external financing. The results of this study will also help policymakers for other Asian economies where the capital markets are underdeveloped and where firms have higher leverage ratios, such as Thailand, Indonesia and Malaysia.

This is the first study in Pakistan that has used a multivariate approach to classify firms into their different life-cycle stages and to discover the leverage adjustment rates of firms during those life-cycle stages.

Given the limited literature on depression as a contributing factor to compulsive social media use, the present research examines the role of perceived depressive mood (PDM) in developing compulsive social media use behavior. The authors also identify and hypothesize channels such as contingent self-esteem (CSE), social interaction anxiety (SIA) and fear of negative evaluation (FNE), which may explain how PDM affects compulsive social media use.

The research model was empirically tested with a survey of 367 Chinese university students using structural equation modeling by drawing on the escape and self-presentation lenses.

The findings indicate that PDM contributes to compulsive social media use behavior both directly and indirectly through CSE. Furthermore, the impact of CSE on compulsive social media use is mediated by the FNE, whereas SIA fails to mediate this effect.

The results can advance the authors’ knowledge of the role and process by which depressive mood impacts compulsive social media use. These findings may add insights into psychological treatment and help in, for example, developing counseling programs or coping strategies for depressed people to protect them from using social media excessively.

This research identifies the pathway mechanism between PDM and compulsive use of social media. It also increases the understanding of how CSE and social interaction deficiencies contribute to compulsive social media usage (CSMU).
