This study examines the relationship of auditor tenure and audit quality in four European countries, namely Germany, France, Italy and Spain, with the innovative GMM (Generalized Methods of Moments) model during the period from 2005 to 2013.
Two GMM methods are used with two alternative definitions of crisis – the main and the robustness method. The results agree regardless of the fact that some of the control variables are excluded in the robustness test.
The results support the finding that in Spain, there is an impact of auditors’ long-term tenure on discretionary accruals, affecting auditors’ quality and independence indirectly. In addition, the crisis affected Germany and France as far as the change in negative and positive values of GDP is concerned. In this respect, the crisis affected the above two countries when the years before and after the crisis are considered as a robustness check. The results contain important implications for accountant regulators and policy makers.

East African firms are experiencing economic growth and are attracting foreign investment in the form of equity capital and loans. However, there are concerns about whether the structure of the capital and managerial ownership of these firms can influence their growth. The study examined the relationship between capital structure and firm value in East African countries and how managerial ownership influences this relationship. Sixty-five (65) listed firms in East Africa were selected for the study. The study employed a GMM estimation technique. The evidence showed that leverage has a significantly negative impact on the value of firms in East Africa, suggesting that higher debt would result in a decrease of firm value. The implication of this result is that firms can increase their value by reducing their leverage level. Moreover, the study found that managerial ownership had an inverse and significant impact on the relationship between leverage and firm value. The conclusion is that leverage decreases the value of firms in East Africa. Another conclusion is that owner-managers can use debt capital more effectively to increase firm value than non-owner managers. The implication of this result is that firms managed by owners can borrow more for their operations because it would increase the value of the firms. This study is the first to examine how managerial ownership moderates the relationship between capital structure and the value of firms in East Africa, which has a unique political, social, cultural and economic environment.

The purpose of this paper is to empirically investigate the impact of capital structure decisions on firm performance in Jordan (2010–2018), as well as the extent to which firm size matters in the capital structure-performance relationship. The dependent variable was market share. The main independent variables were the book value of total debt ratios, and firm-specific factors such as firm size, firm age, firm growth, and market-to-book value of equity served as control variables. This study used a quantitative research method using panel data analysis of 830 firm-year observations. Random effects model was employed to analyze the capital structure-performance nexus. To infer correctly, the main analysis was re-examined using the generalized method of moment estimator to overcome possible endogeneity concerns. After controlling for endogeneity and firm heterogeneity, this study finds that the book value of capital structure has a significantly positive relation to a firm’s market share. Hence, every one unit increase in the book value of total debt ratios will increase market share by 4.77%. The firm size, sales growth, and market-to-book value of equity had a significantly positive association with market share. Hence, every one unit increase in firm size, growth and market-to-book equity ratio will increase a firm’s market share by 8.84%, 2.06%, and 2.15%, respectively, but surprisingly, firm age did not meaningfully contribute to operating performance. Another important finding was that the strength of a positive relationship between the book value of total debt ratios and market share depends on the size of a firm and is mostly higher for larger-sized firms. Hence, every one unit increased in the book value of total debt ratios for large firms will increase market share by 10.58%.
