We examine whether an incremental rolling incentive scheme (IRIS) can enhance innovation under performance based regulation (PBR). Under an IRIS, the firm is awarded for a full PBR term the incremental profit generated by a cost reduction regardless of when the cost reduction is implemented. An IRIS enhances incentives for innovation toward the end of a PBR plan and also ensures immediate implementation of achieved cost reductions. However, an IRIS can reduce incentives for innovation early in a PBR plan. On balance, an IRIS often reduces innovation when the regulated firm has limited ability to delay the implementation of achieved cost reductions. More generally, an IRIS can enhance innovation.
