Abstract

Purpose

The purpose of this paper is to empirically investigate the effect of real credit ratings change on capital structure decisions.

Design/methodology/approach

The study uses three models to examine the impact of credit rating on capital structure decisions within the framework of credit rating-capital structure hypotheses (broad rating, notch rating and investment or speculative grade). These hypotheses are tested by multiple linear regression models.

Findings

The results demonstrate that firms issue less net debt relative to equity post a change in the broad credit ratings level (e.g. a change from A- to BBB+). The findings also show that firms are less concerned by notch ratings change as long the firms remain the same broad credit rating level. Moreover, the paper indicates that firms issue less net debt relative to equity after an upgrade to investment grade.

Research limitations/implications

The study covers the periods of 2009 to 2016; therefore, the research result may be affected by the period specific events such as the European debt crisis. Moreover, studying listed non-financial firms only in the Tadawul Stock Exchange has resulted in small sample which may not be adequate enough to reach concrete generalization. Despite the close proximity between the GCC countries, there could be jurisdictional difference due to country specific regulations, policies or financial development. Therefore, it will be interesting to conduct a cross country study on the GCC to see if the conclusions can be generalized to the region.

Originality/value

The paper contributes to the literature by testing previous researches on new context (Kingdom of Saudi Arabia, KSA) which lack sophisticated comparable studies to the one conducted on other regions of the world. The results highlight the importance of credit ratings for the decision makers who are required to make essential decisions in areas such as financing, structuring or operating firms and regulating markets. To the best of the authors’ knowledge, this is the first study of its kind that has been applied on the GCC region.

Abstract

Purpose

Over the last decade, investments in green energy companies have witnessed noticeable growth rates. However, the glacial pace of the world economic restoration due to COVID-19 pandemic placed a high degree of uncertainty over this market. Therefore, this study investigates the short- and long-term relationships between COVID-19 new cases and WilderHill New Energy Global Innovation Index (NEX) using daily data over the period from January 23, 2020 to February 1, 2023.

Design/methodology/approach

The authors utilize an autoregressive distributed lag bounds testing estimation technique.

Findings

The results show a significant positive impact of COVID-19 new cases on the returns of NEX index in the short run, whereas it has a significant negative impact in the long run. It is also found that the S&P Global Clean Energy Index has a significant positive impact on the returns of NEX index. Although oil has an influential effect on stock returns, the results show insignificant impact.

Practical implications

Governments have the chance to flip this trend by including investment in green energy in their economic growth stimulation policies. Governments should highlight the fundamental advantages of investing in this type of energy such as creating job vacancies while reducing emissions and promoting innovation.

Originality/value

First, as far as the authors are aware, the authors are the first to examine the effect of oil prices on clean energy stocks during COVID-19. Second, the authors contribute to studies on the relationship between oil prices and renewable energy. Third, the authors add to the emerging strand of literature on the impact of COVID-19 on various sectors of the economy. Fourth, the findings of the paper can add to the growing literature on sustainable development goals, in specific the papers related to energy sustainability.

Abstract

Purpose

This paper aims to investigate the determinants of capital structure for non-financial listed firms in the United Arab Emirates (UAE) for the period 2004-2010. The contradiction between the different capital structure theories, limited literature on UAE and its distinctive characteristic of tax-free environment were the motivation for this paper.

Design/methodology/approach

The authors used two panel data techniques to estimate the regression models, and a series of robustness checks.

Findings

The authors find that growth opportunities, size, profitability and liquidity are the main determinants of leverage. The results support the argument of the inadequacy of one capital structure theory, although the results are more inclined toward the pecking-order level.

Practical implications

The results provide a comprehensive overview of the capital structure in the UAE; this information will be of use to managers, shareholders and lenders.

Originality/value

The findings of this paper contribute to the debate of the dominance of capital structure theories. The results also add to the strand of literature on the capital structure of firms in the Middle East, as the authors provide a comprehensive investigation of the determinants of capital structure in UAE non-financial firms.
