Incentive Contract Design and Employee-Initiated Innovation: Evidence from the Field*

This study examines how the design of incentive contracts for tasks defined as workers' official responsibilities (i.e., standard tasks) influences workers' propensity to engage in employee-initiated innovation (EII). EII corresponds to innovation activities that are not formally assigned to workers but are nonetheless encouraged and considered to be important for the company's success. Like other extra-role behaviors, EII is difficult to incentivize directly. Therefore, it is important to understand whether and how explicit incentive contracts designed for the workers' standard tasks may indirectly influence their EII activity. We use field data from a manufacturing company that uses a dedicated information system to track workers' EII idea submissions. We find theory-consistent evidence that, compared to workers receiving fixed pay, employees rewarded for their standard tasks with variable compensation contracts exhibit a lower propensity to engage in EII. This result is concentrated among ideas benefiting other constituents and activities beyond the proponents' standard task (i.e., broad-scope ideas). In contrast, we find no difference attributable to standard task incentive design in the proposal of innovation ideas narrowly focused on the proponent's standard task (i.e., narrow-scope ideas). Our findings suggest that variable pay narrows employees' conceptual focus around the standard task and hinders employee engagement in broad-scope innovation activities compared to fixed compensation contracts. We contribute to the literature on incentives for innovation by showing that standard task compensation contracts have spillover effects on EII behavior. We also contribute to the nascent literature on EII by showing that innovation types, defined based on their relation with the proponent's standard task, matter. Our results are relevant for practitioners in that managers relying on variable pay contracts to incentivize standard task performance should expect lower employee engagement in broad-scope EII.
