This study investigated the impact of the COVID-19 crisis on firm risk and performance in different country-level governance qualities in the MENA region. Analyzing a sample of 739 non-financial listed firms in 12 MENA countries for the period 2011–2020, we found that the COVID-19 crisis negatively impacted the performance of firms, especially low-performance firms, in most industries, and increased firm risk in general. Moreover, we found that national governance quality plays an important role in mitigating the negative impact of the COVID-19 crisis on firm operations. Specifically, national governance quality reduces the negative impact of the COVID-19 crisis on firm performance and the positive impact of the crisis on firm risk. The results are consistent with our contention that national governance quality contributes to creating a positive environment for businesses activities and reducing economic shocks.

Purpose: This paper aims to document the impact of corporate cash holdings on firm performance in Middle East and North African (MENA) emerging markets. The authors also examine how the quality of national governance shapes the interaction between corporate cash holdings and firm performance.Design/methodology/approach: The authors employ data from non-financial firms listed on the stock markets of twelve MENA countries between 2004 and 2018. The empirical model avoids the shortcomings of the prior literature by applying a dynamic framework to the relationship between cash holdings and firm performance.Findings: This research reports a significant positive relationship between corporate cash holdings and firm performance. The results appear to be more pronounced in countries with strong national governance and more developed institutional settings. The findings demonstrate that most benefits of corporate cash holdings can be achieved under strong institutional settings. The authors argue that the positive impact that national governance has on individual firms by reinforcing investors' protection and lowering agency problems increases the added value of cash holdings.Practical implications: The findings should encourage local authorities and policymakers to reinforce the law and instigate new regulations to strengthen the quality of national governance and restore the integrity of local markets.Originality/value: Prior studies have largely been silent on how national governance can shape the relationship between corporate cash holdings and firm performance. This paper draws attention to this issue within the context of MENA emerging markets. To the authors' best knowledge, this is the first study that explores the interaction between cash holdings, firm performance and national governance in MENA emerging markets.

This paper examines the effect of economic policy uncertainty (EPU) on firm-level investment and corporate financial leverage. The panel data of 1072 firms traded on the New York Stock Exchange (NYSE), New York Stock Exchange Market (NYSE MKT) (formerly known as American Stock Exchange—AMEX), or NASDAQ over the period 2012–2021 was analyzed using the fixed-effect model. The empirical results show that the financial leverage of a firm is negatively affected by EPU. Additionally, EPU depresses firms’ investment decisions and debt financing. Our results are robust when alternative measures of our main variables are used.

This research argues that national governance quality may moderate the relationship between COVID-19 and stock returns across markets. Building on the well-established relationship between COVID-19 shock and stock returns, we focus on how the quality of a country’s governance system affects the relationship between the COVID-19 crisis and stock returns. Using data from the World Governance Indicators, the World Bank, and the John Hopkins University Coronavirus Resource Centre (JHU-CRC) for 29 OECD markets from 23 January to 31 December 2020, our findings confirm this hypothesis. Our results suggest that, the estimated coefficient on the interaction term is negative (−0.004) and statistically different from zero at the 5% level of significance. This result can be inferred that the higher the national governance quality is, the weaker the effect of COVID-19 on stock returns will be. Specifically, the negative impact of COVID-19 on stock market returns was more pronounced in countries where the national governance quality index is lower. Our results also show a strong negative association between COVID-19 and stock market returns across the sample. The results are robust to changes in governance quality measures, estimation methods, and explanatory variables. The results have several policy implications such that better institutions may partially offset the adverse impact of the COVID-19 shock on stock market returns.
