摘要:This study analyzes the relationship between a CEOs leadership style and firm performance under conditions of perceived environmental uncertainty. It also seeks to determine whether the impact of the CEOs leadership on a firms subjective and objective performance is significantly different. This study considered the leadership styles of owner-managers and compared the effect of transformational and transactional leadership on both objective and subjective firm performance. Results supported the view that a transformational leadership style of a CEO who owns and operates a firm positively influences both the objective and subjective performance of the firm. Under uncertain conditions, the impact of the CEOs transformational leadership style on firm performance became greater. The CEOs transactional leadership style, contrastingly, was not found to significantly impact the firms objective performance. The impact of a CEOs transactional leadership style on the firms subjective performance was found to be greater in a context of high uncertainty.
