By lowering downstream inventories, QR may compromise retailer incentives to exert sales effort on a manufacturer's product and may lead instead to greater sales effort on a competing product. Manufacturer-initiated quick response can therefore back. re, leading to lower sales of the manufacturer's product and, in...

Prior theory has argued that quality certification is important in markets characterized by information asymmetry. However, there is limited understanding of the contingent factors that influence the efficacy of the quality signal. We focus on capability maturity model (CMM) certification, which is granted on the basis of a rigorous audit of software vendor's internal q...
