Performance, Career Dynamics, and Span of Control
研究管理幅度受经营规模效应影响的理论，并引入企业对管理者能力的动态学习过程，利用单一企业数据验证了规模效应和学习共同决定管理幅度。
In this paper we focus on a classic idea concerning span of control, which is that a prime driver is the scale of operations effect. We extend the theory concerning the scale of operations effect by allowing firms’ beliefs concerning a manager’s ability to evolve over the manager’s career. We empirically investigate the resulting testable predictions using a unique single-firm data set that contains detailed information concerning the reporting relationships at the firm. Our empirical analysis supports the notion that the scale of operations effect and learning are both important determinants of a firm’s span of control.
