Personal reputation has been argued to demonstrate important influences on work outcomes. However, substantive research on personal reputation is relatively scarce. This two-study investigation empirically supports and extends existing theory regarding the temporal development of personal reputation (i.e., antecedents and consequences), and thus contributes to a more informed understanding of both the construct and criterion-related validity of this important construct. Study 1 is conducted longitudinally, in order to assess the development of personal reputation over time, which is undertaken to demonstrate the effects of human capital and social effectiveness as antecedents of reputation. Study 2 complements and extends the first study by conducting a field investigation examining the effects of time, human capital, and social effectiveness as antecedents of personal reputation, while also exploring the reputation consequences of autonomy, power, and career success. Our findings suggest that human capital, time, and social effectiveness play a part in the development of a reputation. Furthermore, career success, power, and autonomy were shown to be outcomes of the reputation construct. Contributions and strengths of this investigation, limitations, and directions for future research are discussed.
