High self esteem improves self confidence and decision making abilities could be positively affected by combination of self-esteem and self confidence. Furthermore, decision making needs emotional intelligence, intuition, contingent knowledge about organization, maturity and experience.
High self-esteem is associated with professional and organizational commitment. Managers who have professional commitment and organizational commitment will not have unethical behavior and decisions. Self-confidence is also one of the dimensions of self-esteem.
self-Confidence differs with over confidence. Overconfidence, , will have a negative impact on managers' decisions. In my opinion, what is best for managers to consider in their decisions is self-efficacy rather than confidence. Because, according to Bandura's theory, self-efficacy is one's belief in the attainment of goals. But self-confidence is a little different and does not indicate confidence. For example, I'm sure I will fail.
