An Experimental Study of Endogenous Discretionary Controls on Employee Effort

Discretionary controls are controls that can be applied at the ex post discretion of the superior rather than being supported by pre-committed enforceable contracts. This study examines employees' effort levels when a discretionary control is endogenously present (chosen by the superior) relative to when it is exogenously present (assigned by the experimenters). Results from our gift-exchange experiment regarding superiors' choice of a discretionary control run counter to prior research on superiors' choice to use pre-committed controls in two important ways. First, we find employee effort is unaffected by the superior's choice of a discretionary control relative to when it is exogenous. That is, the intentional choice of a discretionary control does not seem to be resented by the employee. Second, we find employee effort is lower when superiors choose not to have a discretionary control present relative to when it is exogenously unavailable. That is, we not only find no reward to forgoing a discretionary control, but rather a cost to not choosing a discretionary control. In sum, our results support the prevalence of discretionary controls in practice.
