Assessing the financial performance of airlines in the Asia-Pacific region

This research is aimed at analyzing the causality puzzle on the correlation between financial leverage and systematic risk (beta). Financial leverage and beta are usually considered as two proxies of risk derived from different domains: one ends at financial decision outcome, and the other points to market. Cross-sectionally, this result does not support the moderating-variable impact of size on the relation between financial leverage and systematic risk. On the other hand, however, the moderating-variable impact of industry and operating leverage (to some extent) on the relation between financial leverage and systematic risk were well documented. Inter-temporally, financial leverage is significantly and symmetrically related to beta, not moderated by size and operating leverage. This means that the two variables show bidirectional causality. This study contributes to the new insight that financial leverage and beta are the two variables with bidirectional causality, showing that in the long run, risks from fundamental (financial/micro-economy) and from market (macro-economy) are tightly linked to each other inter-temporally.

Disclosure plays an important role for information users. Voluntary disclosure is more meaningful for stakeholders in order to make appropriate decisions. The article researches the impact of firm characteristics on the voluntary disclosure of the top 50 listed firms in Forbes Vietnam (50 listed firms) from 2015 to 2019. It uses the ordinary least squares of time-series data to test the regression model. The signaling and agency theory is used to explain the relationship between firm characteristics on voluntary disclosure. The research results show three variables of firm characteristics that positively impact the voluntary disclosure of 50 listed firms, including firm size, growth rate of market share value to book value, and audit type, in which audit type has the strongest influence. Accordingly, the state agencies of Vietnam should encourage 50 listed firms to improve the Vietnamese listed firms’ voluntary disclosure and meet international economic integration.

Real earnings management comprises the intervention by managers intending to change business strategies or policies to achieve specific goals. The paper aims to examine trends and levels of real earnings management in the context of the COVID-19 pandemic in Vietnam. The study uses time series data, and the sample includes 1,800 observations from 2016 to 2021. The methods of the study are regression analyses of the real earnings management model. The results indicate that the COVID-19 pandemic positively and significantly affected real earnings management of companies listed on the Vietnamese stock exchange. The trends and levels of real earnings management in the context of the COVID-19 pandemic increase depending on the severity of the pandemic. In terms of applications, the study provides evidence that the quality of financial reporting is lower during the pandemic. Listed enterprises in Vietnam are using high financial leverage, leading to a higher vulnerability to shocks such as the pandemic. Therefore, the real earnings management technique mainly used by managers is operating cash flow adjustment by using income maximization strategies to increase the ability to borrow capital to maintain business operations. The study suggests that the choice of income maximization or income minimization strategy depends mainly on commitments with the capital provider (credit institutions), specific contexts, and economic factors.
