Studies of small and medium-sized enterprises have provided evidence that CEOs of such firms can have a dominating influence on firm activities. Drawing on upper echelons theory, we analyze the influence of CEO personality (CEO internal locus of control), CEO ownership and CEO education on the evaluation of middle manager performance. In line with our expectations, we find evidence for a direct effect of CEO ownership (negative) and CEO education (positive) on the use of objective performance evaluations and for a direct effect of the CEO's internal locus of control on the use of subjective performance evaluations. Moreover, we provide evidence for a moderating role of both CEO ownership and education with respect to the influence of the CEO's locus of control on the use of subjective evaluations. We use a sample of 247 small and medium-sized manufacturing firms to test our hypotheses.

Thesis (M.Com. (Accountancy))--University of the Witwatersrand, Faculty of Commerce, Law and Management, School of Accountancy, 2015 / Many studies considering the effects CEOs‟ characteristics have on the companies they run have been carried out in America. This study considers if organisational outcomes and strategic choices are partially predicted by managerial background characteristics as put forward by Hambrick and Mason (1984). It attempts to determine if the personality traits of CEOs of JSE listed companies (which result in them being classified as a narcissist) have an impact on the financial performance on the company for which they work. As identified by Chatterjee and Hambrick (2007), prior research has explored how executive‟s characteristics are manifested in organisational outcomes, however very little research addresses the narcissistic aspect of CEOs personalities. This study explored whether a relationship exists between CEO narcissism and strategic dynamism in a nonprobability, convenience sample.. A 5-item narcissism index was used as a proxy for narcissism and financial leverage, overhead efficiency and plant and equipment newness, were used to measure strategic dynamism. Multiple regression was used to analyse the data by applying CEO narcissism as the independent variable, strategic dynamism as the dependents variable whilst including control variables, including the CEO tenure, the age of the CEO, the age of the company, and indicator variable for the presence of a COO, the phase of the economy during which the CEO served his tenure and an indicator variable for which industry the company is operating in. The results of this study revealed that there is a viii correlation between the level of narcissism, captured using unobtrusive measures, of a JSE listed company‟s CEO and the level of strategic dynamism of that company. The results of the regression models suggest that whilst there is no observable relationship between narcissism and strategic dynamism, there is a relationship between narcissism and two of the components of strategic dynamism, financial leverage and plant and equipment newness. This research contributes further to the study of the effect of narcissistic CEO‟s on the companies for which they work and suggests that the personality traits of CEOs should be considered by company boards and shareholders when deciding to elect a person as CEO as well as by investors when deciding which companies to invest in.
